Well, Indy's response was very professional and knowledgeable.. wish i could be like that :P Just wanted to comment on your hopes for yield... If you could put 30 plants under a 400 watt light you still wouldnt get 2 lbs.. anyone that tells you they did is lying. I get an average of 2.5 ounces of dried and cured buds from each of my 12 plants, and this only occurs now because there is almost 3000 watts of hps light on them. The right strain grown properly could yield as much as 4 oz's per plant but that will never happen under a 400 watt light. More light, more yield! :rastasmoke:

Good luck
