CANNABIS GROW GUIDE
Section 1: Choosing a space to grow
Choosing a space to grow indoors is just as important as choosing the proper space outdoors. Your garden should be located in an out of the way place (not the bedroom). Basements, attics, and closets are all great places. Once you have a few possibilities in mind make sure the have access to electrical outlets. Plan ahead for anything that might require a repairman to visit your house. If your garden is located in the same room as the furnace, and the furnace explodes, your in big trouble. Once the permanent garden location has been selected it is time to prepare it. (For the rest of this document I will assume you have chosen a closet as the grow space) Paint the walls flat white. Do not use tin foil because it can actually focus light like little laser beams and burn holes through the leaves. Next, cover the floor of the closet with plastic. This will help stop water damage to the floor.
Section 2: Containers
Your plants will need to be grown in some kind of cannabis or container. Large plastic pots (like the ones bushes come in) work best. Fill the bottom inch with large gravel to help drainage. And the rest with high quality potting soil with some sand mixed in. Buckets can also be used but drill drainage holes in the bottom. If your containers previously held other plants then they must be sterilized with bleach or alcohol.
Section 3: Ligthing
Since there is no sun in your closet you will have to provide a sun loving plant like cannabis with alot of artificial light. There are three options available to the grower: flourescent lights are cheap, efficient, and don't put out much heat. Metal halide, or MH bulbs, are more expensive but put out much more light than flourescents. They also put out more heat so ventilation is needed. MH bulbs also require a separate ballst in order to work. High Pressure Sodium lamps, or HPS, put out as much light as MH lamps but with a little less heat. Ventilation and a separate ballast are also required.
Flourescent lights are the cheapest light to use. They run at about $2 a tube. They produce little heat so ventilation may not be needed unless the space is very small. The light spectrum put out by these lights is suitable for all stages of growing. Because flourescents disperse light over a large area, they need to be kept within three inches of the tops for the plants to receive enough light. This means you will have to mount the lights in a way that the can be raised everyday.
Metal Halide Lights
Metal halide lamps put out the most light. They also produce alot of heat. A strong fan is needed to keep room tempertures down. MH lamps put out light mostly in the blue spectrum. Blue light is used best by the plant during vegative growth. MH lights can also be used for flowering with no adverse effects. A separate ballast is required for these lights to work. They come in sizes from 40 to 1000W. One 1000W lamp will provide enough light in a closet to grow four plants.
High Pressure Sodium Lights
High pressure sodium lamps put out almost as much light as MH and with less heat. Good ventilation is still required though. HPS lamps produce light in mostly the red and orange end of the spectrum. The plants uses this light best when flowering. HPS lamps can also be used for vegative growth with little slow down in foliage production. HPS lamps require a separate ballast for operation.
Some growers switch between MH and HPS depending on what stage the plants are in. MH is used in vegative growth and then the light is swithched over to HPS once flowering begins. Most growers use flourescents to start seedlings and root clones. The flourescents are weaker than the MH and HPS lamps and therefore do not stress them too much. Choose whatever light is best suited for your situation. If your are growing in your attic go with MH or HPS. If your growing in the closet like us, then use flourecents. (For
