The closet is approximately 5 x 2.5 x 8; for the lights I was planning on just using 6 26w CFLs; and as for the filtering, I'm looking to do a DIY carbon filter. I'm also going to angle the passive intake at 90 degrees to keep light from escaping.

...and after more poking around on here I just noticed that a lot of this information is already in this post: http://boards.cannabis.com/1634834-post6.html. Blah. Well, any other input is definitely welcome. The more information the better.

Actually, here is a question I have that doesn't seem to be addressed there: is it possible for a fan to be *too* powerful for the dimensions of the area? I'm sorry if this is an incredibly stupid question, I just want to make sure.
