Urdedpal,
I was thinking about using this idea, but I need some advice.
I want to try a first time cabnet grow, I live in central florida, and its coming up on winter time. Wold it be better to blow cool air from my room IN under the door, or out from inside the closet? keeping in mind it will be pretty cool in my room. will have a couple CFLs on for veg, and will get a 400w HPS for bloom time.
Also, how much will the HPS heat up the closet, and should I blow air over it?

EDIT: only 1-3 plants about 2'x3'x5'

Thanks
JD
