Hi everyone. I've been reading grow guides and past posts on the subject but haven't quite had all my questions answered. I hope somewhere here can help. The closet I plan to use is fairly large. Not having the exact measurements, I'd say 7 feet tall, 5 feet wide, and 5 feet deep. I figure I can probably grow (to flowering-after killing off any males) 2-3 plants comfortably in there without them running out of room. Would a 400 watt hps be overkill for just 3 plants? Too much heat for just a closet? I've read something about using one type of lighting for veg. growth and 1 type for flowering. If so, which is it? Also, I'm concerned about how to properly ventilate the closet. Someone mentioned getting a bathroom fan kit. I do rent the townhouse I live in so I am concerned with making any sort of "permanent" changes to the place and pissing off the landlord. Security isn't a problem, as he's never been here once in the two years I've lived here but I would like to get my security deposit back once I do move. I don't think I could even hook something like that up if I tried. I'd probably electrocute myself. So, does anyone have any "non-technical" ideas? I've thought about taking a few inches off the bottom of the door (I could replace it later for $20) and keeping a fan behind it, constantly blowing out air. Would that work? I think I even read somewhere that during dark periods, leaving the door open to bring in fresh air and carbon dioxide works, as well. Thoughts? Sorry for all the questions. I just so want my plants to turn out as best they can. Jeez, I'm this worried about them and I haven't even received my seed order yet! Thanks to anyone who can enlighten me here. This is by FAR the best grow forum I've been to!
