Closet curiosity

i use an air cooled hps lamp so most of my heat gets ducted out with 4in tubing.

 

a pair of 140 mm computer fans running at 9V ontop of the closet should do it

 

i vent mine into the adjoining roomnext to the closet, i cut a hole in each wall ,, [ the closet wall, and the rooms wall] these can easily be patched. when you move. a normal 6'' fan draws the heat out of the room, and blows it all into the adjoining room.

this in combination with the fan you have in the room for circulation,, will create a positive air flow movement,, it will draw air in,, and it will push air out at the same time..

if you look in my grow journal below,,, youll see a good picture of this fan setup i got....its the gray fan on the right side of the pic.
