ok, i only have a basic knowledge of growing, but heres what i know: you want atleaste 75-150w of output on for each plant, you germinate between wet paper towels, transplant them to 100 percent organic sterilized potting soil, and water for a couple of weeks, keeping them on a strict lighting schedule of 18 hours of light a day, and when they show sex, the females will have little hairs where the branches go out from the main stock. the males will have little balls that are pollen sacks. kill the males. then switch the females to 12 hours of light a day, untill 75 percent of the hairs on the buds are brown/orange. then you quit giving it fertilizer, just water for 2 weeks. then you take the plants, cut them at the base of the stock, then cut off all the leaves, leaving only stem and bud. hang it in a dry space to dry.

o and for ferts, during the veg stage (before they show gender) keep em on a (12-0-0) fertilizer, then when they show sex and you kill the males give them a (0-12-12).

as far as the harvest goes, you should get about 1/2 a gram per watt of light.

o and you should keep fans blowing on the plants to simulate wind, increasing stock strength, and to keep it cool, because the lights produce a lot of heat. hope that helps.
