well i got like a 3x4 or 3x5 and bout 7 feet high space so if I can keep the stank down I'm probably just going to end up growing 3-4, figure I might as well if that can bump it up to the mh/hps and guarantee it. I'm thinkin about making a 6 foot box that could slide on in the corner of my closet. I got a ac unit/fan, ceiling fan, and a couple small ones so I think I could keep the temp/air flow pretty decent. by fold out closet I mean it doesnt have a door that opens and closes, has two halves that split in two and fold up at the side.
