you should really consider a fan, theres a lot to be said for moving air through the grow room, so a fan does two jobs really...provides fresh air and controlls temps.

deffinatly money well spent

on my first grow i got about 1 dry ounce per plant(6 plants) with a 400whps, and thats with beginners mistakes like bad soil, irregular watering etc.
babystarbud Reviewed by babystarbud on . closet grow/ possible with no ventilation? ive succesfully grown with cfls in a closet before, but id like to upgrade to a 400watt or so, hps light. do any of you guys think that a closet with plastic on the walls, could withstand a 400w hps without ventilation? ( i would be opening the door for fresh air every hour or two, and have fans running inside ofcourse) i'd be happy for any feedback or advice:smokin: Rating: 5
