not knowing your strain and a ton of other variables makes any answer wrong. If you can fit a 1000 in there or even better 2 600's and ventilate+circulate the air allot, depending on how tall you veg and how you train... anywhere from .5 oz to 2 oz per plant. maybe more or less. LOL

If you are really concerned about higher yield you can move to hydro later...
copobo Reviewed by copobo on . Medical grow question... Hi guys, I'm considering a grow to cover my personal medicinal needs and wanted to get some advice before setting out. I would've posted this in the "grow" section but I've noticed that the responses in that forum aren't always that great for these types of "yield" questions. Anyway, I'm caregiver for my girlfriend as well, and a friend of hers may possibly be giving me caregiver status as well. So, I'll have 6-9 plants flowering at once and I can build a space anywhere from 9 sq ft - Rating: 5
