heavy, your gonna get like 2-3 ounces per plant.

u need your light cycle to be on 18/6 for veg, then after like 1-2 month (depending on what size u want), turn in into 12/12 for flowering

u need also good lights, no cheap normal home light. metal halide is best for veg and hps for flowering. bulbs can be ok too.

a fan helps a lot to make the air circulate. ferts need to be used after like 2 weeks. well that an overall but good luck.
