Oregano, Dill, Basil, Sage and other herbs are all easy to grow. Mint will take over the whole yard if you let it. Fresh mint and celantro are incredible in salads and oriental dishes, and tomatoes are a must for any garden, inside or out. But it all comes down to a truly motivational herb that is your friend and mine, a great healer and teacher to those that know it well. Most people think of gardens as a seasonal, yearly project, but it's actually less time consuming and more rewarding to keep the garden going year round. If one were to attempt to grow year round, indoor gardening techniques will be needed at least during winter to keep the garden producing. You will have herb fresh at all times, there is no worry of mass storage thru the winter and spring, it requires less space, and once established, requires only minimal attention every week to keep it producing at optimal levels. GENETICS AND THE PLANT It's very important to start with good genetics. You should attempt to find seeds from local gardeners that are acclimated and bred for local climate and best floral characteristics. Potency, aroma, fast growth, early maturation, resistance to fungus and pests. All of these factors are considered by the seasoned gardener and you will benefit enormously if you can find a friend to get you started on the journey that never ends... Attempt to find an Indica/Sativa hybrid if possible, as this will have the best high and good characteristics for indoor growth as well. Indica plants have a heavy, stony high that is tiresome, and sativas' are hard to grow indoors due to high light requirements, so a hybrid of this type can be bread that will have the energetic, cerebral high of the sativa and the early maturation tendencies of the Indica plant. The Indica plant is easily recognized by its extremely broad leaves that are very rounded on the sides. The Sativa has very narrow, finger-like leaves. A hybrid will have qualities of both and have leaves that are a cross of these two types, thinner than an Indica, but much broader than a Sativa. It is possible to recognize a good hybrid by the leaves once you know what to look for. Look for seeds that are dark brown or light grey. Some may have dark lines inset into these colors, like tiger stripes. INDOORS & OUTDOORS - CONSTANT HARVEST STRATEGY One of the best solutions to energy vs. output for most home gardeners is to use outdoor light for flowering and use continuous light indoors for germination and vegetative growth. This will take advantage of the natural light/dark cycle and cut your energy use in half compared to the same operation indoors. A small greenhouse can be built of Filon fiberglass sheets that is innocuous and looks much like a storage shed or tool shed so it's not likely to raise suspicions. In winter, indoor space is used to start new seedlings or cuttings to be placed outside in the spring, using natural sunlight to ripen the plants. This routine will provide at least 3 outdoor harvests per year. If more space is available to constantly be starting indoors and flowering 2nd harvest plants outdoors, harvests are possible every 30 days in many areas, with a small indoor harvest in the winter as a possibility as well. The basic strategy of year round production is to understand the plant has two growth cycles. At germination the plant enters into a vegetative state and will be able to use all the continuous light you can give it. This means there is no dark cycle required. The plant will photosynthesis constantly and grow faster than it would outdoors with long evenings. Photosynthesis stops during dark periods and the plant uses sugars produced to build during the evening. This is not a requirement and the plant will grow faster at this stage with continuous photosynthesis (constant light). Once the plant is 12-18" tall, weather permitting, it can be forced to start flowering by placing it outside. Moving the plants to 12-13 hour light periods (moving it outside) with uninterrupted darkness will force the plant to flower. It will ripen and be 2-3' when ready to harvest. When a plant is moved from continuous indoor light to a 10-14 hour day outside, it will start to flower in anticipation of oncoming winter. Vegetative starts moved outside in spring will be ripe by May 30. Vegetative starts moved outside on May 30 will be ripe by July 30. Starts moved outside Aug 1 are picked by Oct. 1st and so on. Operations are moved indoors and a winter crop is planted for seed in anticipation of planting outdoors the next summer, or just for some extra winter stash. PLANTING INDOORS A small indoor space should be found that can be used to germinate seeds; these vegetative starts are placed outside to mature in the spring after last freezes are over. The space can be a closet, a section of a bedroom, a basement area, an attic or unused bathroom. Some people devote entire bedrooms to growing. The space must be light leak proofed, so that no suspicious light is seen from outside the house. This could invite fuzz or rip-offs. The space should be vented. Opening the door of a closet can be enough ventilation if the space is not lit by big lights that generate a lot of heat. Separate exhaust and incoming air vents are best. One at the top of the room to exhaust air into the attic or out the roof, and one to bring in air from an outside wall or under-floor crawl space. Use fans from old computer cabinets, available from electronic liquidators for $5-10 each. Line the walls with aluminum foil, dull side out to diffuse the light and prevent hot-spots, or paint the walls bright white to reflect light. Aluminized mylar, 1 mil thick is about $20 for 25 feet of a 4' wide roll is best. Mirrors are not good to use, since the glass eats light. Line the floor with plastic in case of water spills, etc. Set up a voltage interrupt socket and be sure the electrical wiring will handle the lamps your going to use. A shelf above the main grow area can be used to clone cuttings and germinate seedlings. It will allow you to double the area of your grow space and is an invaluable storage area for plant food, spray bottles and other gardening supplies. Hang a light proof curtain to separate this shelf from the main area when used for flowering. This will allow constant lights on the shelf and dark periods in the main grow area. Velcro can be used to keep the curtain in place and ties can be used to roll it up when tending the garden. A 6" square containers will allow for 4 plants per square foot. You may also gauge by the size of your growing tray (for passive hydroponics); I like kitty litter boxes. ($.80 each, on sale.) Planted 4 per square foot, a 12 sq. ft. closet will be enough space for 48 plants if you have all floor space available. Now you need light. A couple of shop lights will be fine if you just want to start plants inside and then take them outside to grow in a small greenhouse. Shop light fixtures waste some light, so some growers mount 4 lamps on a piece of plywood, with individual reflectors made of curved aluminum sheet bent into a U shape to focus all the light downward. This is for advanced gardeners that have run out of other projects in the garden and I recommend just using the shop light fixtures as is, at least to start with. They can be purchased with bulbs for about $10 each, or without bulbs for around $8. Try to find them on sale. Use one Cool White and one Warm Light type bulb in each to get the best light spectrum possible for plant growth. Do not use expensive Grow Lamp type bulbs, as they do not put out as much light, and therefor do not work as well in most situations (go figure). SHELF GROWING Shelf gardening with fluorescents may be the trend of the future, since the materials are so inexpensive, and easy to obtain. Fluorescent lamps are great for shelf gardening. In this system, many shelves can be placed, one above the other, and fluorescent lamps are used on each shelf. Some shelves have 24 hour lighting, some have 12 hour lighting (for flowering). Two areas are best, perhaps with one other devoted to cloning and germination of seed. Shelf gardening assumes your going to keep all plants 3' or shorter at maturity, so all shelves are 3-4 feet apart. Less light is necessary when you have plants that are this short and forced to mature early. One drawback to a shelf garden like this is that it is very time consuming to adjust the lamp height every day, and it is impossible to take a vacation for even a week with no tending of the garden. This applies mostly to the vegetative stage, when plants are growing as much as an inch per day. Lamps on the flowering shelves are not adjusted nearly as often. An alternative is to use fluorescent lamps for cloning, germination and early seedling growth, then switch over to HPS for growth and flowering. This may be the best solution for the average home grower, since it will allow you to go on vacation if you don't have new starts to attend to. Start new plants when you get home, and position the HPS such that it won't need adjustment for several weeks. Most HPS installations will not require lamp height adjustment. Just attach the lamp to the underside of shelf or ceiling as high as possible, and if you want to get a few plants closer to it, put them on a box or table to get them closer to the lamp. A shelf is all that is necessary with this type of setup, preferably at least 18" wide, up to about 24" maximum. This area must be painted a very bright white, or covered with aluminum foil, dull side out to reflect light back to the plants. Paint the shelf white too. Or, use aluminized mylar, space blanket, or any silvery surface material. Do not use mirrors, as the glass soaks up light. Hang the lamps from chains and make sure you can adjust them with hooks or some other type of mechanism so the lamps can be kept as close to the plants as possible at all times. If the lamps are too far from the plants, the plants will grow long, spindly stems trying to reach the lamp, and will not produce as much bud at maturity as a normal plant. This is due to internode length being much longer. This is the length of stem between each set of leaves. If it is shorter, there can be more internodes, thus more branches, thus a plant that provides more buds in less space at harvest time. Shelf gardening is sometimes referred to as Sea of Green, because many plants are grown close together, creating a green canopy of tops that are grown and matured quickly, and the next crop is started and growing concurrently in a separate area of continuous light. Clones are raised in a constant light shelf, until they start to grow well vegetatively, then placed on a 12 hour per day shelf to flower. Of course, sunlight is free, and the wise grower understands the meaning of the word: subterfuge. LIGHT Indoors, 2000 lumens per sq. ft. is about as low as you want to go indoors. If you get under this mark, plant growth will certainly not go as fast as possible, and internode/stem length will increase. Also, light distance to plants will be much more critical. Daily adjustments to the lamps will be necessary, meaning you get no vacations. 2500 lumens psf should be a good target, and 3000 is optimal if your going to inject or enrich CO2 levels (more on that later). High Intensity Discharge lamps are the best solution for most indoor growers. HID lamps come in 3 basic flavors: High Pressure Sodium (HPS), Metal Halide (MH) and Mercury Vapor. Metal Halide is an improved spectrum, higher intensity Mercury Vapor design. HPS is a yellowish sort of light, maybe a bit pink or orange. Same as some street lamps. HPS lamps can be used to grow a crop from start to finish. Tests show that the HPS crop will mature 1 week later than a similar crop under MH, but it will be a bigger yield, so it's better to wait the extra week. The easiest HID to buy, and least expensive initially are the florescent and mercury vapor lamps. MV will put out about 8000 lumens per 175 watts, and 150 watts of HPS will go about 15k lumens, so HPS is almost twice as efficient. But the color spectrum from HPS lamp output is not as good. HPS is high in reds, which works well for flowering, while the Metal Halide is rich in blues, needed for the best vegetative growth. Unfortunately, MV lamps provide the worst spectrum for plant growth, but are very inexpensive to purchase. 400 watt HPS will output around 45k lumens. For every 500 watts of continuous use, you use about $20 a month in electricity, so it is evident that a lamp taking half the power to output the same lumens (or twice the lumens at the same power level) will pay for itself in a year or so, and from then on, continuous savings will be reaped. This is a simple initial cost vs. operating costs calculation, and does not take into account the faster growth and increased yield the HPS lamp will give you, due to more light being available. If this is factored into the calculation the HPS lamp will pay for itself with the first crop, when compared to MV or fluorescent lamps, since it is easily twice as efficient and grows flowers faster and bigger. Lamp Type Watts Lumens per bulb Total efficiency Fluorescent Bulb 40 3000 400 watts = 30k lumens Mercury Vapor 175 8000 400 watts = 20k lumens Metal Halide 400 36000 400 watts = 36k lumens High P. Sodium 400 45000 400 watts = 45k lumens Notice the Mercury Vapor lamps are less efficient than the fluorescent, and can not be positioned as close to the plants, so the plants will not be able to use as much of the MV light. The light distribution is not as good either. MV lamps use more wattage for a given lumen output, but are easier to hang than ten 40 watt florescent bulbs. There is a new type of HPS lamp called Son Agro, and it is available in a 250, 1000, and 400 watt range. I think the 400 is actually 430 watts; they have added 30 watts of blue to this bulb. It is a very bright lamp (53k lumens) and is made for greenhouse use. These bulbs can be purchased to replace normal HPS bulbs, so they are an option if you already own a HPS lamp. The beauty of this bulb is that you do not give up most of the advantages of MH lamps, such as minimal internode spacing and early maturation, like most HPS users do, and you have all advantages of a HPS lamp. One bulb does it all. Internodal length of plants grown with the Son Agro are the shortest ever seen with any type of lamp. Plants grown under this lamp are incredibly bushy, compact and grow very fast. Son Agro bulbs however, do not last as long as normal HPS bulbs. There is something like a 25% difference in bulb life. Metal Halide (MH) is another option, and is available in both a 36k and 40k lumen bulbs for the 400 watt size. The Super Bulb (40k) is about $10-15 more, and provides an extra 4000 lumens. I think the Super Bulb may last longer; if so, that makes it the way to go. Halide light is more blue and better than straight HPS for vegetative growth, but is much less efficient than HPS. It is possible to purchase conversion bulbs for a MH lamp that convert it to HPS, but the cost of the conversion bulb is more expensive than the color corrected Son Agro bulb, so I would recommend just buying the Son Agro HPS. Even though it costs more initially, you get more for your energy dollar later, and it's much easier to hang than 10 fluorescent tubes. If you have a MH 36k lumen lamp burning at 400 watts and a 53k lumen HPS burning at 430 watts, which is better efficiency wise? Which will provide a better yield? Obviously, the Son Agro HPS, but of course, the initial cost is higher. Actually, the ballast will add about 10% to these wattage numbers. I think the Son Agro bulb will prove much better than the MH for any purpose. The MH bulb does not last as long, but is cheaper. Compare $36 for a 400 watt MH bulb vs. $40 for the HPS bulb. Add $15 for the Son Agro HPS. The HPS bulb life is twice as long. 10k hours vs. 21k hours. The Son Agro is 16k hours or so. Still, longer bulb life and more light add up to more for your energy dollar long term. I tried to find lamps that were not so expensive. While MV is cheap, it's not very efficient and costs a lot to operate several lamps. It is more difficult to hang several lamps. Horizontal mounting of any HID is a good idea, as this will boost by 30% the amount of light that actually reaches the plants. HPS is much less expensive to operate, but only comes in the 70 watt size at the home improvement stores. This size is not very efficient, but blows away MV in efficiency, so they might be an alternative to MV for very small operations, like 9 sq. feet or less. Over 9 sqr. feet, you need more light than one of these can provide, so you go to 2. 70 watt HPS lamps cost about $40 each, complete. Two lamps would be 140 watts putting out about 12k lumens, so it's better than MV, but a 150 watt HPS puts out about 18k lumens, the bulb life is longer, bulbs are cheaper and the lamp more efficient to operate. The biggest problem is that the mid size lamps like the 150 and 250 watt HPS are almost as expensive to buy as the larger 400's. Heat buildup in the room is a factor with HID lamps, and just how much light the plants can use is determined by temperature, CO2 levels, nutrient availability, PH, and other factors. Too big of a lamp for a space will make constant venting necessary, and then there is no way to enrich CO2, since it's getting blown out of the room right away. Other issues come up, in that the bulb cost on the 70 watt HPS is $24, the 150 is only $30, and the 400 is only $40. So you will spend more to replace two 70 watt bulbs than you will to replace one 400 watt HPS. Go figure. Add that up with the lower resale value on the 70's (practically nothing) and the fact that they are being modified and are not suited to this application, and it becomes evident that $189 for a 250 HPS lamp, or $219 for a 400, might just be worth the price. Here is the breakdown on prices (from memory): Type Complete Cost Bulb Cost Bulb Life Lumens HPS 400 $219 $40 18k hours 50k MH 400 $175 $37 10k hours 36k Son Agro400 $235 $55 15k hours 53k Super MH400 $190 $45 ?? 40k MH 250 $149 $32 ?? 21k HPS 250 $165 $36 ?? 27k HPS agro250 $180 $53 ?? 30k MH 150 $139 $25 ?? 14k HPS 175 $150 $30 ?? 17k SEA OF GREEN Sea of Green is the theory of harvesting lots of small plants, matured early to get the fastest production of fruit available. Instead of growing a few plants for a longer period of time, in the same space many smaller plants are grown that mature faster and in less time. Thus, less time is required between crops. This is important to you when the electricity bill comes each month. One crop can be started while another is maturing, and a continuous harvest, year round can be maintained. 9 plants per square foot will be a good start for seedlings, and perhaps even maturity. 4 plants per square foot will allow plenty of room for each plant to grow a large top area, but will not allow for much bottom branching. This is OK since indoors, these bottom branches are always shaded anyway, and will not grow very well unless given additional light and space. Cut these bottom branches and use the cuttings to start new plants. This creates more air flow around the plants and helps avoid fungus and humidity problems. The plants, if started at the same time, should create what is called a "green canopy" that traps most of the light at the top level of the plants. Little light will penetrate below this level, since the plants are so close together. The gardener is attempting to concentrate on the top of the plant, and use the light and space to the best advantage, in as little time as possible. Use of nylon poultry fence or similar chicken wire laid out over the green canopy will support the plants as they start to droop under the weight of heavy fruiting tops. Stakes can be used too, but are not as easy to install for plants in the middle and back of the room, where reach is more difficult. It's easy to want big plants, since they will produce more yield per plant, but it's usually better with limited space to grow smaller plants that mature faster and pack into smaller spaces. This is called Sea of Green, and was developed in Holland. Instead of fitting 4 large plants in that small room, fit 12 small ones on a shelf above 12 other small plants. These plants take only 3-4 months to mature, and harvesting takes place constantly, since there is both a vegetative and flowering area devoted to each, with harvests every 45-60 days. It's not the size of the plant, but the maturity and quality of the product that counts, and it's a sure bet you can fit many smaller plants into a small space with less wasted area than 4 large ones. You can also grow them twice as fast, so harvests take place twice as often. The key here is to get good at picking early flowering plants, and to propagate only those that are of the best quality. Get good at cloning, and your monocrop will be incredible. It's good to avoid "topping" your plants if you want them to grow as fast as possible. It's better just to grow 2 or 4 times more plants, since they will produce more, faster, in the same space. Sea of Green entails growing to harvest the main cola (top) of the plant. Bottom branches are trimmed to increase air flow under the "blanket" of growing tops. Use these cuttings for clones, as they are the easiest part of the plant to root. It's also the fastest part of the plant to regenerate after flowering has occurred. Don't pre-force plants so you can discard males early. This takes a lot of time. Just cover one branch per plant with black paper (light tight, breaths air) to force pre-flowers and differentiate early. How many plants to grow indoors per square foot? You will have to experiment, and I would venture the optimum is somewhere between 1 and 9 per squ. foot. If you subdivide one square foot, 4" square containers would allow 9 plants per square foot. This is about the size of a half-gallon milk carton, cut tall for deep root growth. GERMINATION Germinate seeds in sterile soil (for planting outdoors) or a hydroponic medium of vermiculite. Use a Jiffy cube #7 to germinate seeds in, or make your own from gauze netting and vermiculite. Keep them moist at all times. When the seed sprouts, place the jiffy cube in bigger container or directly into a hydroponic medium. Make sure the medium is kept moist at all times, but not wet. A cut-down milk carton with holes in the bottom, set in a tray with an 1" of water should wick water to the seeds thru the vermiculite. You can germinate seeds in a paper towel. But be very careful, it's easy to ruin roots if they dry out, or are planted too late. Always transplant as little as possible by germinating in the same container you intend to grow the plant in for a significant period of time. 5-55-17 plant food such as Peter's Professional will stimulate root growth of the germinating seed and the new seedlings. Use a very dilute solution, in distilled water, about 1/3 normal strength, and keep temperatures between 72-80 degrees. No light is necessary and may slow germination. Place seedlings in the light once they sprout. Plan on transplanting only once or twice before harvest. Use the biggest containers possible for the space and number of seedlings you plan to start. Plants will suffer if continuously transplanted and delay harvesting. You will suffer too, from too much work! Cut holes in the bottom of containers and fill the last few inches at the top with vermiculite only, to start seeds or accept seedling transplants. Vermiculite will tend to wash to the bottom of the container when watered from the top, so this will help with that problem as well. Since vermiculite holds water well, wicks water well, but does not hold too much water, roots always have lots of oxygen, even if they are sitting in a try full of water. A hydrogen peroxide based plant food is used to get extra oxygen to the plants when the pans are kept continuously full. The water can be allowed to recede each time after watering, before new solution is added. This allows the plants roots to dry somewhat, and make sure they are getting enough oxygen. Use SuperSoil brand potting soil, as it is excellent and sterilized. If you insist on using dirt from the yard, sterilize it in the microwave or oven until it gets steamy. Sterilize the containers as well with a bleach solution, especially if they have been used a previous season for another plant. VEGETATIVE GROWTH Once sprouted, the plant starts vegetative growth. This means the plant will be photosynthesizing as much as possible to grow tall and start many grow tips at each pair of leaves. Since most plants have a vegetative stage where they are growing as fast as possible after the plant first germinates from seed, it is possible to grow these plants with no dark period, and increase the speed at which they grow by 15-30&. Plants can be grown vegetatively indefinitely. It is up to the gardener to decide when to force the plant to flower. A plant can grow from 12" to 12' before being forced to flower, so there is a lot of latitude here for each gardener to manage the garden based on goals and space available. A solution of 20-20-20 with trace minerals is used for both hydroponic and soil gardening when growing continuously under lights. Miracle Grow Patio food is good for this. A high P plant food such as Peter's 5-50-17 food is used for blooming and fruiting plants with 12 hour days. Epsom salts should be used in the solution for magnesium and sulfur minerals. Keep lights on continuously for sprouts, since they require no darkness period like older plants; trying to fruit before winter comes. You will not need a timer unless you want to keep the lamps off during a certain time each day. Try to light the plants for 18 or more hours, or continuously at this point. Later, if you want to mature the plants indoors, you will need to cut back light to 12-13 hours with strict, regular uninterrupted darkness to get fruiting plants to produce. Bend the plants stem back and forth to force it to be very thick and strong. Spindly stems can not support heavy flowering growth. An internal oscillating fan will also reduce humidity on the leave's stomata and improve the stem strength as well. HYDROPONIC VEGATATIVE SOLUTION, per gallon: Miracle Grow Patio (contains trace elements) 1/2 teaspoon Epsom salts 1 teaspoon Lime (if not added to medium) 1 teaspoon Human Urine 1/4 cup Oxygen Plus Plant Food (OPTIONAL) 1 teaspoon This mixture will insure your plants are getting all major and minor nutrients in solution, and will also be treating your plants with oxygen for good root growth, and potassium nitrate for good burning qualities. Another good GROWTH PHASE mix is 1/4 tsp Peter's 20/20/20 fertilizer per gallon of water, with trace elements and oxygen added. FLOWERING The the plant will be induced to fruit or flower with dark cycles of 11-12 hours that simulate the oncoming winter in the fall as the days grow shorter. As a consequence, it works out well indoors to have two separate areas; one that is used for the initial vegetative state and one that is used for flowering and fruiting. There is no other requirement other than to keep the dark cycle for flowering very dark with no light interruptions, as this can stall flowering by days or weeks. Once a plant is big enough to mature (18"-18 feet), dark periods are required for most plants to flower and bear fruit. This will require putting the lamp on a timer, to create regular and strict dark periods of uninterrupted light. Give flowering plants high P plant food and keep them on a strict light regimen of 12 hours, with no light, or no more than a full moon during the dark cycle. 13 hours light, 11 dark may increase flower size while still allowing the plant to go into the flowering mode. Use less light, longer dark periods to speed maturity toward the end of the flowering cycle. Two shelves can be used, one identical to the other, if strictly indoor gardening is desired. One shelf's lights are set for 12-13 hours, and one is lit continuously. Plants are started in continuous light, and are moved to the other shelf to flower to maturity after several weeks. This flowering shelf should be bigger than the "starting" or "vegetative" shelf, so that it can accommodate larger plants. Or, some plants can be taken outside if there is not enough space on the flowering shelf for all of them near harvesting. A light tight curtain can be made from vinyl, or other opaque material, with a reflective material on the other side to reflect light back to the plants. This curtain can be tied with cord when rolled up to work on the garden, and can be velcroed down in place to make sure no light leaks in or out. If the shelf is placed up high, it will not be very noticeable, and will fit in any room. Visitors will never notice it unless you point it out to them, since it is above eye level, and no light is being emitted from it. Flowering plants like very high P level foods, such as 5-50-17, but 10-20-10 should be adequate. Nutrients should be provided with each watering when first flowering. Trace elements are necessary too; try to find foods that include these, so you don't have to use a separate trace element food too. HYDROPONIC FLOWERING SOLUTION, per gallon: 1/2 strength high P plant food, such as 4-12-6, or 5-50-17, etc. 1 tspn epsom salts 1 tspn lime (if not part of the medium) 1 tspn Oxygen Plus Plant Food (Optional) 1/2 tspn Trace Element food I cannot stress enough that during the FLOWERING PHASE, the dark period should not be violated by normal light. It delays flower development due to hormones in the plant that react to light. If you must work on the plants during this time, allow only as much light as a VERY pale moon can provide for less than 5 minutes. Keep pruning to a minimum during the entire FLOWERING PHASE. Bring the dark period down to 10 or 8 hours to hasten maturity after flowering for 4-6 weeks. A green light can be used to work on the garden during the dark period with no negative reactions from the plants. These are sold as nursery safety lights, but any green bulb should be OK. Flowering plants should not be sprayed often as this will promote mold and rot. Keep humidity levels down indoors when flowering, as this is the most delicate time for the plants in this regard. HYDROPONICS Most growers report that a hydroponic system will grow plants faster than a soil medium, given the same genetics and environmental conditions otherwise. This may be due to closer attention and more control of nutrients, and more access to oxygen. The plants can breath easier, and therefor, take less time to grow. One report has it that plants started in soil matured after the hydroponic plants started 2 weeks later! Fast growth allows for earlier maturation and shorter total growing time per crop. Also, with soil mixtures, plant growth tends to slow when the plants become root-bound. Hydroponics provides even, rapid growth with no pauses for transplant shock and eliminates the labor/materials of repotting. By far the easiest hydroponic systems to use are the wick and reservoir systems. These are referred to as Passive Hydroponic methods, because they require no water distribution system on an active scale (pump, drain, flow meter and path). The basis of these systems is that water will wick to where you want it if the medium and conditions are correct. The wick system is more involved since the wicks must be cut and placed in the pots, correct holes must be cut in the pots, and a spacer must be created to place the plants up above the water reservoir below. This can be as simple as two buckets, one fit inside the other, or a kiddie pool with bricks in it that the pots rest on, elevating them out of the nutrient solution. I find the wick setup to be more work than the reservoir system. Initial setup is a pain with wicks, and the plants sit higher in the room, taking up precious vertical space. The base the pot sits on may not be very stable compared to a reservoir system, and a knocked over plant will never be the same as an untouched plant, due to stress and shock in recovery. The reservoir system needs only a good medium suited to the task, and a pan to sit a pot in. The other minor factor is an airpump is used to aerate the water, but may be optional. The pots are filled with lava/ vermiculite mix of 4 to 1. This medium will store water, but has excellent drainage and air storage capacity as well. It is also reusable to the extent it can be recaptured from harvested plants. Use small size lava, 3/8" pea size, and rinse the dust off it first. Wet vermiculite (dangerous dry, wear a mask) and mix into pots. Square pots hold more than round. Vermiculite will settle to bottom after repeated watering from the top, so only water from the top occasionally to leach, and put more vermiculite on the top than the bottom. The pan is filled with 1 1/2 - 3 inches of water and allowed to recede between waterings. Every two weeks the plants are watered with no nutrients from the top to leach out mineral deposits. If you go away, reservoirs made of 2 liter soda bottles inverted into a container to fit, and hosed over to the pans with a water level mark and position similar to a pet watering dispenser can be made to keep the plants watered for 2-3 weeks at least. An alternative to air pumping might just be to use the H2O2 (oxygen Plus plant food) instead. Or perhaps both for best results. It may be that only the shake-up aeration is really needed, so this will be a good experiment for the benefit of future generations. Grow some plants with shaken nutrient solution, some with aeration in the pan, some with H2O2, and some with combinations of all 3 together. One really great hydroponic medium is floral foam. Stick lots of holes into it to open it up a little, and start plants/clones in it, moving the cube of foam to lava/perlite later for larger growth stages. Foam rubber, or most types of porous foam, as well as rockwool will be good for this as well. I prefer the floral foam, as it is inert, and adds no PH factors. It's also pretty cheap if you buy the generic brands. Hydroponics should be used indoors or in greenhouses to speed the growth of plants, so you have more bud in less time. Hydroponics allows you to water the plants daily, and this will speed growth. The main difference between hydroponics and soil growing is that the hydroponic soil or "meduim"is made to dry quickly, and drain well so that there are no over-watering problems associated with continuous watering. Also, hydroponically grown plants do not derive nutrients from soil, but from the solution used to water the plants. Plant food is administered with most waterings, and allows the gardener to strictly control what nutrients are available to the plants at the different stages of plant growth. Passive hydroponics is easy with a reservoir system. Only a pot filled with the correct low-moisture medium and a water tray to sit it in are needed. No pumps, hoses or other apparatus is required. The pot is placed in the pan, and watered from the top or directly into the pan. Holes in the bottom and side near the bottom of the pot allows water into the pot, and is wicked up to the roots by the vermiculite. A pot filled with lava and vermiculate should be moist at the top after water is added to the pan. Kitty litter pans can be purchased at five and dime stores on sale for as little as $1 each, and make great water pans. 12-16 cut-down paper milk cartons will fit in each pan. A small closet can easily hold a hundred plants at a time when starting, and can hold 40-50 for harvesting. Hydroponic medium will act as a soil, but be sterile, and inert, with few if any nutrients of its own, usable by the plants. A great medium is 3/8" lava mixed with vermiculite. Vermiculite is a PH neutral substance made of mica that is mined from the earth. It is sterile and will not pass on germs, fugus and pests to the plants, so it is much safer than planting in soil, unless you use the best sterilized plant soils available. Mix lava with vermiculite 4-1 for a medium that holds water well, but gets a lot of oxygen to the roots. Wash the lava rock repeatedly to get most of the dust out of it, before using it. Mix some domite lime, or seashell lime, one tablespoon per gallon of medium to provide nitrogen and minerals for the plants. Plants do not grow well and suffer from lack of oxygen in many potting soils. If you plant in soil, use Super Soil brand potting mix, as many potting soil brands are mostly wood and do not provide many nutrients for the plants. Planting can be made easier with hydroponic mediums that require little setup such as rockwool. Rockwool cubes can be reused several times, and are premade to use for hydroponics. There are disadvantages to rockwool that I won't go into here. Some advantages of rockwool are that it is impossible to over water and there is no transplanting. Just place the plant's cube on top of a larger rockwool cube and enjoy your extra leisure time. I find it best to save money by not buying rockwool and spending time planting in soil or hydroponic mediums such as vermiculite/lava mix. Pearlite is nice, since it is so light. Pearlite can be used instead of or in addition to lava, which must be rinsed and is much heavier. Watering can be automated to some degree with simple and cheap apparatus, so take advantage of this when possible. Hydroponics will hasten growing time, so it takes less time to harvest after planting. It makes sense to use simple passive hydroponic techniques when possible. Hydroponics will not be desirable if your growing outdoors, unless you have a greenhouse. CAUTION: it is necessary keep close watch of plants to be sure they are never allowed to dry too much when growing hydroponically, or roots will be damaged. If you will not be able to tend to the garden every day, be sure the pans are filled enough to last until next time you return, or you can lose your crop easily. Plants in soil are much easier to care for in this respect, since moisture storage crystals can be added to the soil to buffer water for long periods between watering. If you need to, it is possible to automatically regulate the water level in hydroponic pans by toilet bowl float in a master reservoir, or using a gurgle bottle that holds water and adds it as the level recedes, like a pet watering bottle used for dogs and cats. Also, a pump can be put on a timer to add water to the pans. If your watering every day hydroponically, you may be able to water twice a day if you increase ventilation and make sure the plants don't build up too much humidity. You can water more often (and thus pump the plant more often) if you have slightly warmer temperatures, less water retention in your medium, and better drainage, or all of the above. What counts is that your watering more often, but still allowing the medium to dry between waterings. Change the solution every month if your circulating it with a pump, but the reservoir system does away with this problem. Just rinse the medium once a month or so to prevent salts build up. Change plant foods often to avoid deficiencies in the plants. I recommend using 2 different plant foods for each phase of growth, or 4 foods total, to lessen chances of any type of deficiency. Change the solution more often if you notice the PH is going down quickly (too acid). Due to cationic exchange, solution will tend to get too acid over time, and this will cause nutrients to become unavailable to the plants. Check PH every time you water. Watch out for alga and higher humidities in hydroponics when pumping plants. A layer of gravel at the top of the pot may help, since it will dry very quickly. Make sure your not over-watering soil potted plants, by allowing them to fully dry out after each pump. One way to pump a reservoir hydroponic plant when your at home, is to water it more often from the top, and not allow too much to stand in the pan. That way, the planting medium dries in a day or even an afternoon, and you can water every day, or more than once a day, completely drenching the plant, increasing nutrient intake, while allowing the plant to dry each time. Be careful! If you forget to fill the pan and your gone more than a day, your plants could die. Obviously, this works out better when the plants are indoors, or close to the house in a yard or greenhouse. RECYCLING Use pots made from squarish containers such as paper milk cartons, plastic water jugs, etc. More plants will fit in less space and have more rooting area if square containers are used. This makes your garden a recycling center, and saves you tons of money. PLANTING OUTDOORS Outdoors, it's a good idea to use soil if you don't have a green house, since hydroponics will be less reliable outside in the open air, due mostly to evaporation. Exposure is all important when locating a site for a greenhouse or outdoor plot. In the winter, you need to know where the sun shines for the longest period in your yard, and privacy and other factors will enter in as well. Try to find an innocuous spot that gets full winter sun from mid morning to mid afternoon, at least from 10-4, preferably 8-5. This will be really asking for a lot if you live north of 30 degrees latitude since days are short in winter. Since most gardeners will not want to use the greenhouse in the middle of the winter, you can still use winter sun as an indicator of good spring and fall lighting exposures. Usually the south side of a hill gets the most sun. Also, large areas open to the sun on the north side of the property will get good southern exposures. East and West exposures can be good if they get the full morning/afternoon sun and mid-day sun as well. Disguise your greenhouse as a tool shed, or similar structure, by using only one wall and a roof of Filon, and using a similar colored material for the rest of the shed. Try to make it appear as if it has always been there, with plants and trees that grow around it and mask it from view while allowing sun to reach it. Filon (corrugated fiberglass) sheets can be used outside to cover young plants grown together in a garden. Buy the clear greenhouse sheets, and opaque them with white wash (made from lime) or epoxy resin tinted white and painted on. This will pass more sun than white Filon, and still hide the plants. Epoxy resin will preserve the Filon for many more seasons than it would otherwise last. Dig a big hole, don't depend on the plant to be able to penetrate the clay and rubble unless your sure of the quality of topsoil in the area. Grassy fields would have good top soil, but your back yard may not. This alone can make the difference between an average 5' tall plant, and a 10' monster by harvest time. You may want to keep outdoor plants in pots so they can be easily moved. A big hole will allow the pot to be place in it, thus reducing the height of the plant. SOIL GROWING Use Super Soil brand in CA, as this is the only known soil on the West Coast that is guaranteed to be good. Many other brands are mostly wood products and have very few nutrients, are too moist, etc. Add vermiculite, pearlite or sand to Super Soil to increase it's drainage and aeration. Use P4 water crystals in the soil to give the plants a few days worth of emergency water reserves. This substance swells up with water and holds it like a sponge, so that roots will have a reserve if harsh drought makes constant watering necessary. Go real easy on this stuff though, it tends to sink to the bottom of the pot and suffocate bottom roots (new growth roots) and stunts the plant. Use in extreme moderation, let it swell up for at least 45 mins, preferably and hour before mixing with other soil. Plant size in soil is directly related to pot size. If you want the plant to grow bigger, put it in a bigger pot. Usually, 1/2 gallon per foot of plant is sufficient. A six foot plant would require a minimum of a 3 gallon pot. Remember, square containers have more volume in a square space (like a closet). SUBTREFUGE Its interesting that pot plants really do blend in with other plants to the point that they are unidentifiable by all but the most observant. I remember a relative of the family on a visit to Texas showed me his corn in the garden and I was standing 12" from several pot plants before I recognized them for what they were. Plants started outdoors late in the season never get very big and never attract the least bit of attention when placed next to plants of similar or taller stature. Even tall plant grown among several trees will be almost invisible in their camouflage. Outdoors the object is to control access to an area, and not to arouse suspicion. Tucking them here and there, never in a recognizable pattern. Space them out, and fit them in to the existing landscape such that they get full sun, but they're hidden or blend in. Visit the plants at night on full moons, and if your visible to neighbors, appear to be pruning a tree, mowing the lawn, or doing something in the yard that looks makes you invisible. Dig a hole and put a potted plant in it. The plant's height will be reduced by at least a foot, maybe 2 or 3 feet if it's a big hole. Make sure your plants are out of sight, take a different route to get to them if they are not in a secure part of your property, and cover the trail to make it look as if there is no trail. Make cut backs in the trail, so that people on the main trail will tend to miss the cut-back to the grow area. Don't park on the main road, always find a place to park that will not arouse suspicion by people that pass on the road. Have a safe house in the area if you are not planting close to home. Always have a good reason for being in the area and have the necessary items to make your claim believable, (i.e., a fishing pole if you claim your fishing). Briar and poison oak patches are perfect if you know how to cut through Poison Oak to be washed away before an allergic reaction takes place. Try to plant under trees, next to bushes and keep only a few plants in any one spot. Train or top the plants to grow sideways, or do something to prevent the classic christmas tree look of most plants left to grow untrained. Tying the top down to the ground will make the plants branches grow up toward the sun, and increase yield, given a long enough growing season. Plants can be grown under trees if the sun comes in at an angle and lights the area for several hours every day. Plants should get at least 5 hours of direct sun every day, and 5 more hours of indirect light. Some growers top the plant when it is 12" high, and grow the 2 tops horizontally along a trellis. The plant will never be over 3 feet tall, and never arouses suspicion from neighbors. This type of plant can even be grown outdoors in full view if you don't arouse suspicion by your being in the area (like your own back yard, or land near your home). PLANT FOOD AND NUTRIENTS Plant foods have 3 main ingredients that will be the mainstay of the garden, Nitrogen, Phosphorus, and Potassium. These 3 ingredients are usually listed on the front label of the plant food in the order of N-P-K. A 20-20-20 plant food has a Nitrogen level of 20%. Secondary nutrients are Calcium, Sulphur and Magnesium. In trace quantities, boron, copper, molybenum, zink, iron, and manganese. Depending on stage of growth, different nutrients are needed at different times. For rooting and germination, levels of high P nutrients with less N/K are needed. Vegetative growth needs lots of N, and human urine is one of the better sources, (mix 8 ounces to 1 gallon water), although it is not a complete fertilizer unto itself. 20-20-20 with trace elements should do it; I like Miracle Grow Patio food. Watch for calcium, magnesium, sulfur and iron levels too. These are important. One tablespoon of dolomite or hydrated lime is used per gallon of growing medium when a hydroponic medium is first brought on-line, to provide nitrogen, calcium and magnesium. Epsom salts are used to enhance magnesium and sulphur levels in solution. Tobacco grown with potassium nitrate burns better. Plant foods with PN (P2N3) are foods such as Rapid Grow and Miracle Grow. This is an excellent fertilizer for vegetative growth, or through the flowering cycle as well, when pumping the plant. Consider however, potassium nitrate is also known as Salt Peter, and is used to make men have less sexual desire or impotent, such as in mental institutions. So if certain plants are destined for cooking, you might use Fish Emulsion or some other totally organic fertilizer on these plants, at least in the last weeks of flowering. "Pumping" is when you use more waterings to make the plants grow faster. This is dangerous if you proceed in a reckless manner, due to potential over-watering problems. You must go slowly and watch the plants daily and even hourly at first to be sure your not over-watering the plants. Use weaker plant food mixtures than normal, maybe 25%, and be sure your leaching once a month and running straight water through the plants at least every other time you water. Use of light strength Oxygen Plus plant food (or Food Grade Hydrogen Peroxide) allows the roots to breath better and prevents problems with over-watering. Check soil to be sure there are no PH anomalies that might be due to Hydrogen Peroxide in the solution. (One experienced grower told me he would not use H2O2 (HP) due to possible PH problems. This should not be a problem if your checking PH and correcting for it in watering solutions. Until further experience verifies use of HP as not a problem, we will consider it an optional measure if your worried about over-watering problems.) Be sure your medium has good drainage. At this point, if your watering soil based plants once a week, you can water every 3-5 days instead if you plant them in a medium with better drainage. Pearlite or lava rock will greatly increase the drainage of the medium and make watering necessary more often. This will pump the plants; they will tend to grow faster because of the enhanced oxygen to the roots. Make sure the plant medium is almost dry before watering again, as the plant grows faster this way. An alternative is to use a standard plant food mixture (stronger) once every 3 waterings. The nutrients are suspended in the medium and stored in the soil for later use. The nutrients are washed out by 2 straight waterings afterward and there is no salts build up in the soil. Stop all plant food 2 weeks before harvesting, so that the plants don't taste like plant food. WARNING: Do not over-fertilize. It will kill your plants. Always read the instructions for the fertilizer being used. Use 1/4 strength if adding to the water for all feedings and 1/2 strength for hydroponics. Use as recommended if adding to water 1 out of 3 times you water in soil. Novice growers tend to over-fertilize their plants. PH AND FERTILIZERS PH can make or break your nutrient solution. 6.7-6.2 is best to ensure there is no nutrient lock-up occurring. Hydroponics requires the solution to be PH corrected for the medium before exposing to the plants. Vinegar can make the PH go down, and potash can take it up when it gets too acid. Buy a PH meter for $10 and use it in soil, water, and hydroponic medium to make sure your not going alkaline or acid over time. Most neutral mediums can use a little vinegar to make them just this side of 7 ph to 6.5 or so. Most fertilizers cause a ph change in the soil. Adding fertilizer to the soil almost always results in a more acidic ph. As time goes on, the amount of salts produced by the breakdown of fertilizers in the soil causes the soil to become increasingly acidic and eventually the concentration of these salts in the soil will stunt the plant and cause browning out of the foliage. Also, as the plant gets older its roots become less effective in bringing food to the leaves. To avoid the accumulation of these salts in your soil and to ensure that your plant is getting all of the food it needs you can begin leaf feeding your plant at the age of about 1.5 months. Dissolve the fertilizer in worm water and spray the mixture directly onto the foliage. The leaves absorb the fertilizer into their veins. If you want to continue to put fertilizer into the soil as well as leaf feeding, be sure not to overdose your plants. FOLAIR FEEDING Foliar feeding seems to be one of the easiest ways of increasing yield, growth speed, and quality in a well vented space, with or without elevated CO2 levels. Just prepare a tea of worm castings, fish emulsion, bat guano, or most any other plant food right for the job and feed in vegetative and early flowering stages. It is not recommended for late flowering, or you will be eating the sprayed-on material later. Stop foliar feeding 2-3 weeks before harvesting. Wash off the leaves with straight water every week to prevent clogging the stomata of the leaves. Feed daily or every other day. Best times of day to Foliar feed are 7-10Am and after 5 in the evening. This is because the stomata on the underside of the leaves are open then. Also, the best temperature is about 72 degrees, and over 80, they may not be open at all. So find the cooler part of the day if it's hot, and the warmer part of the day if it's cold out. You may need to spray at 2AM if that's the coolest time available. The sprayer used should atomize the solution to a very fine mist; find your best sprayer and use it for this. Make sure the PH is between 7 and 6.2. Use baking soda to make the solution higher PH, and vinegar to make the solution lower PH. It's better to spray more often and use less, than to drench the plants infrequently. Use a wetting agent to prevent the water from beading up, and thereby burning the leaves as they act as small prisms.Make sure you don't spray a hot bulb; better yet, spray only when the bulb has cooled. Perhaps the best foliar feeding includes using seltzer water and plant food at the same time. This way, CO2 and nutrients are feed directly to the leaves in the same spray. Foliar feeding is recognized in most of the literature as being a good way to get nutrients to the plant later when nutrient lockup problems could start to reduce intake from the roots. It is important to wash leaves that are harvested before they are dried since they will have nitrate salts on them. NOTE: One grower who reviewed this document comments: "Fish emulsion smells. Bat guano could be highly unsanitary. Stick to the Rapid-Gro, MgSO4, hydroponic trace element solution. Nitrate salts (The "N" in NPK) are unhealthy to smoke. Personally, I never foliar feed." CO2 Elevating carbon dioxide levels can increase growth speed a great deal, perhaps even double it. It seems that the plant evolved in primordial times when natural CO2 levels were many times what they are today. The plant uses CO2 for photosynthesis to create sugars it uses to build plant tissues. Elevating the CO2 level will increase the plants ability to manufacture these sugars and plant growth rate is enhanced considerably. CO2 can be a pain to manufacture safely, cheaply, and/or conveniently, and is expensive to set up if you use a CO2 tank system. There are other factors that can help increase yield and growth time that are much less hassle. CO2 is most usable for flowering, as this is when the plant is most dense and has the hardest time circulating air around it’s leaves. If your strictly growing vegetatively indoors, (transferring your plants outdoors to flower), then CO2 will not be a major concern unless you have a sealed greenhouse and wish to increase yield and decrease flowering time. The basic system looks like this: 20 lb tank $100 Regulator $159 Timer or controller $10-125 Fill up $15-20 -------------------------------- Worst case = $395 for CO2 tank setup synced to a exhaust fan with a thermostat. CO2 is cheaply produced by burning Natural Gas. However, heat and Carbon Monoxide must be vented to the outside air. CO2 can be obtained by buying or leasing cylinders from local welding supply houses. If asked, you can say you have an old mig welder at home and need to patch up the lawnmower (trailer, car, etc.) For a small closet, one tank could last 2 months, but it depends on how much is released, how often the room is vented, hours of light cycle, room leaks, enrichment levels and dispersion methods. It is generally viewed as good to have a small constant flow over the plants at all times the lights are on, dispersed directly over the plants during the time exhaust fans are off. Opportunities exist to conserve CO2, but this can cost money. When the light is off you don't need CO2, so during flowering, you will use half as much if you have the CO2 solenoid setup to your light timer. When the fan is on for venting, CO2 is shut off as well. This may be up to half the time the light is on, so this will affect the plants exposure times and amount of gas actually dispensed. Environmentally, using bottled gas is better, since manufacturing it adds to greenhouse effect, and bottled CO2 is captured as part of the manufacturing process of many materials, and then recycled. Fermenting, CO2 generators, and baking soda and vinegar methods all generate new CO2 and add to greenhouse effect. Other alternatives are CO2 generation from fermentation and generators. A simple CO2 generator would be a propane heater. This will work well, as long as the gases can be vented to the grow area, and a fan is used to keep the hot CO2 (that will rise) circulating and available below at the plants level. Fire and exhaust venting of the heat are issues as well. A room that must be vented 50% of the time to rid the environment of heat from a lamp and heater will not receive as much CO2 as a room that can be kept unvented for hours at a time. Fermentation or vinegar over baking soda will work if you don't have many vent cycles, but if you have enough heat to make constant or regular venting necessary, these methods become impractical. Just pour the vinegar on baking soda and close the door, (you lose your CO2 as soon as the vent comes on). This method leaves a great deal to be desired, since it is not easy to regulate automatically, and requires daily attention.It is possible however, to create CO2 by fermentation, let the wine turn to vinegar, and pour this on baking soda. It's the most cost-effective setup for most closet growers, for whom $400 in CO2 equipment is a bit much to swallow. In fermentation, yeast is constantly killing itself, and takes a lot of space to do right. You need a big bin that you can constantly keep adding water to, so that the alcohol levels will not rise high enough to kill the yeast. Sugar is used quickly this way, and a 10 pound sack will run $3.50 or so and last about 2-3 weeks. This is also difficult to gauge what is happening as far as amounts actually released. A tube out the top going into a jar of water will bubble and demonstrate the amount of CO2 being produced. Try sodium bicarbonate mixed with vinegar, 1 tsp: ~30cc- this will gush up all frothy as it releases CO2. do it just before you close the door on your plants. a MUCH cheaper way to provide CO2 is 2 Oz sugar in 2 liters[3 pint~] of water in a bottle [sterilized 1st with bleach and water, then rinsed], plus a few cc urine[!] or if you insist, yeast nutrient from a home brewing supplier. Add a brewing yeast, shake up and keep at 25 deg celsius[~70 F] . over next 2 weeks or so it will brew up about 1/2 Oz CO2 for every Oz sugar used. Keep a few going at once, starting a new one every 3 days or so. With added CO2 growth is phenomenal!!! I personally measured 38cm growth in 8 days under a 250watt HPS bulb[tubular clear, Horizontal mount]. A good container is a 1 gallon plastic milk jug, with a pin-hole in the cap. Also, the air-lock from a piece of clear tube running into a jar filled with water will keep microbes out and demonstrate the fermentation is working. A variation is to spray soda water on the plants twice a day. This is not recommended by some authorities, and receives great raves by people who seem to feel it has enhanced their crop. It stands to reason this would work for only a small unvented closet, but may be right for some situations. It could get expensive with a lot of plants to spray. Use seltzer, not club soda, since it contains less sodium that could clog the plants stomata. Wash your plants with straight water after 2 or 3 seltzer sprays. It's a lot of work, and you can't automate it, but maybe that's good! Remember, being with the plants is a beautiful experience, and brings you closer to your spiritual self and the earth. Seltzer is available at most grocery stores (I get it at Lucky's @ .79 for a 2 litter bottle). Club soda will work if seltzer water is not available; but it has twice as much sodium in it. A very diluted solution of Miracle Grow can be sprayed on the plant at the same time. CAUTION: Don't spray too close to a hot bulb! Spray downward only, or turn off the lamp first. Wash leaves with clear water before harvesting leaf for cooking, since nitrates are not healthy to be smoking or injesting. VENTING You have to vent a lot with a HID lamp, less so for fluorescents. Also, humidity build up requires that you vent at least a few times per day. For a room with a hot lamp that builds up heat quickly, the best vent would be one that cleared the room in 3 minutes, then would go for 27 minutes before venting again, or similarly, vent 3 minutes, shut off 12 minutes, etc. The trick is to find a timer that will do this sort of thing. Not easy to find and not cheap. Once you need to regulate CO2 on and off inversely with the fan, your looking at a $100 climate controller. Alternatives are a thermostat that turns on a fan when a certain temperature is reached, and turns it off when the temp recedes 4 degrees. But it is a bitch to coordinate CO2 release with this one, since you don't know when the fan goes on. $39 for this thermostat, but to sync it to CO2 with a voltage sensing relay is $100 for the ready-made switch, so then the environment controller at $100 is cheaper. All you really want is a fan that clears the air in a few minutes, a temperature switch that turns on and off the fan, and an inverse switch that turns off and on the CO2. If you can vent the room really quick and the heat does not build up too quickly, the CO2 could be run in a slow, continuous fashion, and would build up in-between the occasional quick exhaust cycles. Two timers synced can be used, but the only ones cheaply available are the 30 min interval, 48 trips per 24 hours. So I could have a fan run 30 mins on, then 30 mins off. I could also sync it to the light so that I don't vent when the lamp is off. I can sync this to an identical timer that will turn on CO2 during the time that the fan is not on, and vise versa. It would be difficult to sync them closer that 5-10 mins, but at least there would be a possible inexpensive solution. $20 for two of these timers. Fans are expensive to buy for venting, but I just go down to the local electronic parts liquidators and they have muffin fans for $5-10, so that’s a real savings over the $50-70 these fans cost new at the indoor garden stores. A good vent fan will keep the humidity and temperature down, and distribute CO2 to your plants from new incoming air. Even though CO2 enrichment can mean 30-100% yield increases, the hassle, expense, space, danger, and time involved can make constant or near constant venting a desirable alternative to enrichment. As long as the plant has the opportunity to take in new CO2 at all times, from air that is over 200 ppm CO2, the plants will have the required nutrients for photosynthesis. Most closets will need new CO2 coming in every two or three hours, minimum. Internal air movement is very necessary as well. An oscillating fan should be used to circulate air within the growroom, to help circulate CO2. It will also keep the humidity down, allowing the air to absorb more moisture, and reduce risk of fungus. A wall mount oscillating fan will not take valuable floor space. The best grow rooms have the most internal air circulation. TEMPERATURE Proper temperature is one highly variable factor. Most books state optimum grow temperature to be 70-80 degrees, but many list extenuating circumstances that allow temperatures to go higher. Assuming genetics is not a factor, plants seem to be able to absorb more light at higher temps, perhaps up to 90 degrees. High light and CO2 levels could make this go as high as 95 degrees for increased growth speed.* An optimum of 95 degrees is new data that assumes very-high light, CO2 enrichment of 1500 ppm and good regular venting to keep humidity down. It is not clear if these temperature will reduce potency in flowers. It may be a good idea to reduce temperatures once flowering has started, to preserve potency, even if it does reduce growth speed. But higher temperatures will make plants grow vegetatively much faster, by exciting the plants metabolism, assuming the required levels of CO2 and light are available, and humidity is not allowed to get too high. With normal levels of CO2, in a well vented space, 90 degrees would seem to be the absolute max, while 85 may be closer to optimum, even with a great deal of light available. Do not let the room temperature get over 35 C (95 F) as this hurts growth. Optimal temperature is 27-30 C (80-86 F) if you have strong light with no CO2 enrichment. Less than 21 C (70 F) is too cold for good growth. Low temperatures at night are OK down to about 60 degrees outdoors, then start to effect the growth in a big way. Mid 50's will cause mild shock and 40's will kill your plants with repeated exposure. Keep your plants warm, especially the roots. Elevate pots if you think the ground is sucking the heat out of the roots. This is an issue if you have a slab or other type of cold floor. As temperature goes up, so does the ability of the air to hold water, thus reducing humidity, so a higher average temperature should reduce risk of fungus. Contrary to many reports, high humidity is not good for plants except during germination and rooting. Lower humidity levels help the plant transpire CO2 and reduce risk of molds during flowering. Studies indicate the potency of buds goes down as the temperature goes up, so it is important to see that the plants do not get too hot during flowering cycles. * D. Gold: CO2, Temperature and Humidity, 1991 Edited by E. Rosenthal. PESTS You really have to watch pests, or all your efforts could result in little or nothing in return. Mites and Aphids are the worst; whiteflies, caterpillar and fungi are the ones to watch out for long term. Pyrethrum bombs can start you with a clean slate in the room, and then homemade or commercial soap sprays will do most of the rest. When bringing in plants from outside, pyrethrum every broad leaf top and bottom and the soil too. Then watch them closely for a week or two, and soap down any remaining bug life you find from eggs being hatched. This should do the trick for a month or two, long enough it won't be an issue before harvesting. Fungus is another obstacle in the path of a successful growing season. When the flowers are roughly half developed they become susceptible to a fungus or bud rot. It appears that growing conditions for the fungus are best when temperatures are between 60 and 80 degrees and the humidity is high. The fungus is very destructive and spreads quickly. It is a spore type of fungus that travels to other buds via the wind so it is impossible to prevent or stop if weather conditions permit it to grow. If things should go badly and the fungus starts to attack your plants, you must remove it immediately or it will spread to other areas of the plant or plants. Some growers will remove just the section of the bud that is infected whereas other growers will remove the entire branch. Removal of the entire branch better insures that the fungus is totally re- moved, and also enables the grower to sample the crop a few weeks ahead of time. Fungi can wipe your crop quick, so invest in some SAFE fungicide (Safer makes a good product) and spray down the plants just before flowering if you think fungus may be a problem. Don't spray the plants if you have never had problems with fungus before. Keep humidity down, circulate air like crazy in the grow space and keep unquarantined outdoor plants out of the indoor space. Don`t wait until after flowering, since it's not a good idea to apply the fungicide directly to flowers. Instead, flowers must be cut off when they are infected. Most fungicides are very nasty, and you won't want to injest them, so it is necessary to use one that is safe for vegetables. Safer makes a suitable product that is available at most nurseries. Use soap solution like Safer to get rid of most aphid problems. Use some tobacco juice and chili pepper powder added to this for mites. Dr. Bronnars Soap can be used with some dish detergent in a spray bottle if you want to save money. TRANSPLANTING There will be little or no shock if you are quick and tender in your handling of the plants. Make sure you only need to transplant twice, or better yet, once if possible, through the entire growth cycle. Transplanting slows you down. It takes time, is tricky, and threatens the plants. Start in as large a container as possible, square is best. 16 ounce paper or plastic cups work OK, and 2 litter soda bottles cut down may be big enough for the first harvest when growing hydroponically. One-gallon plastic milk or water containers (squarish) will work too, if you want to work around the handle (really not a problem if you don't mind cutting them up when you transplant later for second harvest). Or start seeds and rooted cuttings in 1/4 gallon paper milk containers, cut and washed in hot, sudsy water to get rid of bacteria in the old milk. It's better to have less seedlings than it is to have many seedlings that need constant transplanting. These larger containers take only a little more space, and allow you to transplant only one time before harvesting the first crop. Transplant into a half-gallon milk carton (cut high for deep roots) before forcing flower growth. To regenerate this plant after harvesting, transplant it into a larger pot after it goes into vegetative growth once again, 5 gallon paint buckets work pretty well if you can spare the space, and a 2-3 gallon container would make this plant’s 2nd harvest better than the first, given enough vegetative regrowth first. One more tip: A Russian study showed that seedlings with at least 4" of soil to grow the tap root were more likely to go female. The source I'm quoting says "This may be why some farmers get female/male ratios as great as 80%/20%." EARLY SEXING It's possible to tell the sex of a plant early, and thus move male plants out of the main growing area sooner by covering a plant's lower branch for 12 hours a day while it's in a constant light vegetative state. Use a black paper bag or equivalent to allow for air flow while keeping out light. Be sure to set up a regular cycle for these covered branches. If light is allowed to reach them during the dark period, they may not indicate early at all. Use a magnifying glass to look at the early flowers sex type. A male plant will have a small club (playing card) looking preflower with a small stem under it. A female flower is usually a single or double pistil, white and wispy. REGENERATION It is possible to harvest plants and then rejuvenate them vegetatively for a 2nd and even 3rd harvest. A second harvest can be realized in as little as 6-8 weeks. Harvested plants come inside for rejuvenation under continuous light. It will take 7-14 days to see signs of new growth when regenerating a plant. As stated before, and in contrast to normal growth patterns, lower branches will be the first to sprout new vegetative growth. Just make sure when harvesting, you leave most healthy fan leaves and a few lower branches of the plant, or even just a few grow tips will do. Since the plants stalk, and roots are already formed, the plant can produce a second, even third harvest of buds in a little more than half the time of the original harvest. Allow the plant to grow a little vegetatively, then take outside again to reflower. Or keep inside for vegetative cuttings. You now have two or three generations of plants growing, and will need more space outside. But you will now be harvesting twice as often. HARVESTING AND DRYING Harvesting is the reaping of the bounty, and is the most enjoyable time you will spend with your garden. Plants are harvested when the flowers are ripe. Generally, ripeness is defined as when the white pistils start to turn brown, orange, etc. and start to withdraw back into the false seed pod. The seed pods swell with resins usually reserved for seed production, and we have ripe sinse buds with red and golden hairs. It is interesting that the time of harvest controls the "high" of the buds. If harvested "early" with only a few of the pistils turned color, the buds will have a more pure THC content and will have less THC that has turned to CBD and CBN's. The lessor psychoactive substances will create the bouquet of the pot, and control the amount of stoneyness and stupidness associated with the high. A pure THC content is very cerebral, while high THC, high CBD, CBN content will make the plants more of a stupid, or hazy buzz. Buds taken later, when fully ripened will normally have these higher CBN, CBD levels and may not be what you prefer once you try different samples picked at different times. Don't listen to the experts, decide yourself based on what you come to like yourself. Do not cure pot in the sun, it reduces potency. Slow cure hanging buds upside down in a ventilated space. That is all that is needed to have great sensi. Drying in a paper bag works too. If your in a hurry, it's OK to dry a small amount in-between paper sheets in a microwave oven. Go slow and check it, don't burn it. It will be harsh smoking this way though. CLONING Cloning preserves the character of your favorite plant. Cloning can make a ocean of green out of a single plant, so it is a powerful tool for growing large crops, and will fill a closet quickly with your favorite genetics. When you find the plant you want to be your "buddy" for the rest of your life, you can keep that plant's genetic character alive for decades and pass it on to your children's children. Propagate and share it with others, to keep a copy, should your own line dye out. Cloning will open you to the risk of a fungus or pest wiping out the whole crop, so it's important to pick plants that exhibit great resistance to fungus and pests. Pick the plant you feel will be the most reliable to reproduce in large scale, based on health, growth rate, resistance to pests, and potency. The quality of the high, and the type of buzz you get will be a very important determining factor. Take cuttings for clones before you move plants from vegetative grow area to the flowering area. Low branches are cut to increase air circulation under the green canopy. Rooted clones are moved to the vegetative growth area, and new clones are started in the cloning area using the low branch cuttings. Each cycle of growth will take from 6-8 weeks, so you can constantly be growing in 3 stages, and harvesting every 6-8 weeks. If a plant is harvested, you can sample it, and decide if you want to clone it. Pick your favorite 2 or 3 distinctly different types of plants to clone, based on trying the harvested plants. The plants you want to clone can be regenerated by putting them in constant light. In a few weeks, you will have many vegetative cuttings available for cloning and preserving your favorite plants. After two months, any marijuana plant can be cloned. Flowering plants can be cloned, but the procedure may take considerably longer. Its best to wait, and regenerate vegetatively plants that have been harvested. A single regenerated/harvested plant can generate hundreds of cuttings. Cut young growth tips from a vegetative stage, mature plant (bottom branches are best) 3-5 inches long with a stem diameter 1/5-1/10 inch. Cut with a sterile razor blade or X-Acto knife (flamed) and immerse the cut end of the clone into a tub of distilled water mixed with 1/4 tspn Peters 5-50-17 per gallon. Next, cut the bottom .2 inch off the end while it is submerged, using a diagonal cut. Remove the clone from the tub and dip into a liquid cloning solution following instructions on the label. Dust with fungicide and place in cloning tray or medium. Flowering plants can be cloned too, but may take longer, and may not have as high a success rate. Cloning goes quickest with the liquid rooting solutions, in a warmed, aerated tray, with subdued lighting and high humidity. In a closet, you can make space above the grow area so that the heat of the lamp warms the tray (passive collecting) and spare the expense and hassle of the aquarium heater ($24) or agricultural heating pad w/ thermostat (pricey). A double 4" fluorescent lamp will be perfect. Leave lamps on for 24 hours a day. Cuttings should root in 2-3 weeks. I found only one liquid rooting hormone solution that was not over $10. (Olivia's Gel was $12 for a 1.6 ounce bottle. Geez, what is this stuff, gold?) I found some dipNgrow for $9, considered myself lucky, and got a tray and clear cover for $4. A clear tray cover or greenhouse encloser is needed to brincover ($4) made for rooting at an indoor gardening supply house. You must keep humidity very high for the clones. It's also possible to directly place a dipped cutting in a moist block of rockwool, floral foam with holes punched, or vermiculite in a cup; be sure to root cuttings in a constantly moist medium. Jiffy peat cubes are not recommended, as published reports indicate results were not good for rooting clones. Place starter cubes in tray of solution. Check twice a day to be sure cubes are moist, not drenched, and not dry. After about 2-3 weeks, rootlets will appear at the bottom of the pods. Transplant at this point to growing area, taking care not to disturb any exposed roots. One grower writes us: I have had virtually all attempted clones root with the following scheme: 0. Prep cutting by removing large leaves on tip to be cut, allow to heal. 1. While holding underwater, take final diagonal cut on stem to be rooted. 2. Dip in Rootone, then spear stem about 2" deep in 16 oz. cups of 1/2 vermiculite, 1/2 perlite, which are kept in a stryrofoam cooler. 3. Spray cuttings with a VERY mild complete fert. soln. 4. Cover top of cooler with Saran Wrap, then punch holes for ventilation. 5. Keep cooler in relatively mild temps, low light, and spray cuttings daily. 6. Cuttings should root in about 3 weeks. Cloning is not as easy as starting from seed. With seeds, you can have 18" tall plants in 6 weeks or less. With clones, it may take 6 weeks for the plant to sprout roots and new growth. Seeds are easily twice as fast if you have empty indoor space being wasted that needs to be put to use quickly. Always breed a few buds for seeds, even if you expect to be cloning most of the time, you could get wiped out, and have nothing but your seeds left to start over. BREEDING It is possible to breed and select cuttings from plants that grow, flower, and mature faster. Some plants will naturally be better than others in this regard, and it is easy to select not only the most potent plants to clone or breed, but the fastest growing/flowering plants as well. Find your fastest growth plant, and breed it with your "best high" male for fast flowering, potent strains. Clone your fastest, best high plant for the quickest monocrop garden possible. Over time, it will save you a lot of waiting around for your plants to mature. When a male is starting to flower (several weeks before the females) it should be removed from the females so it does not pollinate them. It is taken to a separate area. Any place that gets just a few hours of light per day will be adequate, including close to a window in a separate room in the house. Put newspaper under it to catch the pollen as the flowers drop it a few days later. Keep a male alive indefinitely by bending it's top severely and putting it in mild shock that delays it's maturity. Save pollen in an air tight bag in the freezer. It will be good for about a month. It may be several more weeks before the females are ready to pollinate. Turn off all fans. Use a paper bag to pollinate a branch of a female plant. Use different pollen from two males on separate branches. Wrap the bag around the branch and seal it at the opening to the branch. Shake the branch vigorously. Wet the paper bag after a few minutes with a sprayer and then carefully remove it. One pollinated branch can create hundreds of seeds. It should not be necessary to pollinate one branch of each female you wish to cross with a particular female. SINSEMILLIA When the female plant is not allowed to pollinate, it grows full of resin that was intended to make seeds. False seed pods swell with THC laden resin and the pistils turn red and orange and withdraw into the pods. Then the plant is harvested. Seeds are not part of the bud when the flowers mature. This is called Sinsemillia, and simply means "no seeds". SINSE SEEDS It is possible to cross your favorite two female plants to create a new strain of seeds that will produce all female plants. Preferably, these two plants will be different types of plants, not from the same mother's seeds. This will create the best offspring, since it will not lead to inbreeding. It is easier to gauge the quality of female plants than male plants, since the smoke is more potent and easier to judge it's finer qualities. Plants from seeds created in this fashion will be all female plants since there will be no chance of male chromosomes from female parents. Use Gibberellic Acid on one branch of a female plant to induce male flowers. Gibberellic Acid is sold by nursery supply houses for plant breeding and hybridizing. When the male flowers form, pollinate the flowers of your other target female plant you have selected. Just pollinate one branch unless you want lots of seeds! One branch can easily create 100 seeds or more. Once the branch has male flowers, cut the branch and root it in water, with newspaper under it to catch the male pollen when it drops. Use a rooting solution similar to the above cloning solution. To pollinate a branch, use a paper bag over the branch and seal it, then shake it around to pollinate the female flowers. Spray the bag wet to make the pollen stick to the inside of the bag and then take it off the branch. It is also possible to pollinate the flowers of the plant you create the male flowers on, crossing it with itself. This is used to preserve a special plants characteristics. Cloning will also preserve the plants characteristics, but will not allow you to store seeds for use later. ODORS AND NEGATIVE IONS Negative ion generators have been used for years now to cut down on odors in a grow room, but reports are coming in that a negative ion generator will increase growth speed and yield. No true evidence to support this, however it does make sense, due to the fact that people and animals seem to be altered in a positive way by negative ions in the air, so plants may "feel" better too. Try putting one in the grow room. You may notice the buds don't have as much scent when picked, but that may be desirable in some cases. A negative ion generator can be purchased for $15 to $100 depending on the type and power involved. Some have reversed cycles that collect the dust to a charged plate. It is also possible to use grounded aluminum foil on the wall and shelf where the ionizer sits, to collect these particles. Just wipe the foil clean once a month. It should be grounded to an electrical outlets ground wire. If you don't cover the wall and shelf with paper or foil, the wall will turn dark with dust taken from the air, and you will have to repaint that wall later. OXYGEN O2 to the roots is a big concern, since the plant requires this for nutrients to be available, and to rid itself of toxins, etc. One of the easiest things to do is use food grade hydrogen peroxide in the water to increase the availability of oxygen in the water. H2O2 has an extra oxygen atom that will easily break away and can be used by the plant. Oxygen Plus is a plant food that contains 25% hydrogen peroxide and is perfect for this use. Using a planting medium that allows for plenty of aeration is also really important. Be sure you have good drainage by using Perlite, sand, or gravel in your mix and at the bottom of pots. Don’t use a medium that holds too much water, or you may significantly reduce the oxygen available to the plant. More on that in the section on hydroponics. Aerating the water before watering is also a good idea. In the case of soil potted plants, use an airpump to aerate the water overnight before watering your plants, or put the water in a container with a cap and shake it up real good before giving to the plants. SAFETY AND PRIVACY It has been reported utility companies can tell your bill is way off from the same time last year, and police are even finding growers this way, so more than 500 watts in the family home running constantly will show up as a regular monthly increase in electricity use. You can claim space heaters, more people living on the premises, too many television sets, and late hours, if they happen mention it to you (innocently). If the police knock and ask you about it, don't let them in, and move your plants to another location during the wee hours in a vehicle not your own. Upon moving into a new place, it may be desirable to immediately establish high electricity use, so that your electrical use history won't reveal your activities in the future... DISTILLED WATER Some growers report purified or distilled water helps their plants grow faster. Perhaps due to sodium and heavy metals found in hard water that are not present in purified water. Hard water tends to build up alkaline salt deposits in soil that lockup trace minerals, and cause iron, copper and zinc deficiencies. There are several types of purified water, but many are not free of minerals that could be causing salt buildup over an extended period of time. Tap water comes in two flavors. Hot and cold. The cold pipe has less calcium and sodium buildup in it, and should be freer of sediment once the water has been turned on and allowed to flow for 30 seconds. Hot water will have rust, lead deposits, and bough-que sodium and calcium, so much so, you will see it easily. Use only the amount of hot water needed to make the water the correct temperature (70-80 F). Tap water filtered through a carbon (charcoal) filter will be free of chlorine and most large particles, but will still contain dissolved solids such as sodium and heavy metals (lead, arsenic, nickel, etc.). Purified bottled water will be either Reverse Osmosis or some form of carbon/sediment filtered water. When purchasing water at a store, unless it says RO or Distilled, don't bother buying it. It could still have the same dissolved solids and heavy metals your tap water has. Reverse Osmosis filters will drastically reduce the amount of dissolved solids in the tap water. When installed and maintained, it will reduce the heavy metals and salts to minuscule levels, which are then probably safe to drink. While (RO) systems can provide sodium free water, it is not as good as distilled water. If filters and membrane are not changed at least once a year, the system will be drastically reduced in effectiveness. RO systems are expensive initially, but since a large garden alone can take up to 10 gallons of water a week, it will pay for itself in a year or two, compared to buying bottled water. It pays to shop around for these systems, prices vary widely. Distilled water is produced through boiling and steam run-off. It isolates the O2 to its pure form. It contains no pollutants, heavy metals, dissolved solids or chlorine that can react and build up in soils. It is expensive to purchase, but the bottles can be used as plant containers (get the squarish, tall styled plastic bottles) so the expense can be justified for a period of time. Purchasing a distiller is an option. It will have to be maintained (emptied of salts) on a regular basis, and carbon filter changed, but it is a good item to consider if you believe your water to be very hard. Very hard water is very hard on an RO system and a distiller may be the best option if you desire drinking water as well. Drinking distilled water will help your body flush toxins and reduced problems with kidney stones. An alternative to using distilled water is to run the water thorough a sediment/charcoal filter combination to reduce dissolved solids and chlorine, and use a vinegar mix to lower PH in the water and prevent alkalinity buildup. This should make mineral available to the plants, even if salts begin to build up from the wet/dry regimen over an extended time. BIRTH CONTROL PILLS A solution of one pill to one gallon of water has been reported to cause increased growth speed in tomato plants. It is possible this will help herb plants too. One treatment administered before flowering and one administered a few weeks before harvesting might help the plant mature faster. One grower told a story of the same type of plants, one administered the estrogen grew to 20 feet, while the other was 7 feet. This may be purely anecdotal, but it may work. Try it and report back to us on results. SEED AND BUD STORAGE Use a seal-a-meal to hermetically seal the bag with no air inside. Freeze or refrigerate, and bud and seed can be kept for years this way. REVIEW: 1) Light - lots of it, but not too close or you burn leaves. 2) CO2 - if you can stand the hassle; or ferment in an unvented closet. 3) Vent - More air the better. Both in and out of the room and internal. 4) Oxygen - Use H2O2 in solution, and aerate water by shaking and air pump, use Pearlite or lava for increased drainage and oxygen storage. 5) Hydroponics - This will increase both yield and speed of growth over soil. 6) Temperature - The hotter the better if you have enough light and CO2; 70 up to 95 degrees with lots of light and CO2. 7) Nutrients - Make sure your giving the plant what it needs when it needs it. Watch for deficiencies. 8) PH - 6.7 - 6.2 is ideal. Make sure you check the soil/nutrients; match up. 9) Pests - Don't let all the above effort go to waste. Be vigilant. 10) Sea of Green - grow more plants, smaller, faster, with less wasted light and space, using both indoor light, and forcing/ flowering outside where possible. 11) Transplanting - Make sure you only have to transplant 2 times or less through the growth cycle, and do it early. 12) Grow smaller plants on shelves, increasing square footage growing space by 2 or 3 times. 13) Harvest often and sooner with fast maturing clones. 14) Negative ions are good, and make the plants feel better. 15) Purified (RO only) or distilled water may solve chlorine problems and make nutrients more available to the plant. This will insure pollutants and heavy metals are not in the water. 16) Security - make sure your plants are not detected. Don't admit cops into the yard or house without a warrant. A final comment: Good results can be had even in what appear to be rather marginal situations. (i.e.: a four inch pot in a room with a skylight.) With the minimum of: well drained medium, good light with ventilation, regular application of a complete fertilizer, pest control, and avoidance of detection, anyone can take a viable seed to maturity. One need not have a lot of money, or even know-how to grow good plants.
