If your room temps are in the 70's I'd be careful crunning Hps lights in that Cab. they get pretty hot.

I can't toally tell from the picture but that comop fan looks pretty tiny.

I would suggest (im no expert) a bigger just to be safe. More air movment never hurts.

kdspecial Reviewed by kdspecial on . My Grow Box Setup! ~Pics~ Hey everyone, Completely Stoned has been gone for a good long wqhile but now I am BACK! And with a new grow to log for you guys! It's 2 1/2' x 2 1/2' x 4' and its all painted white inside. There's a computer fan in the back panel of the box and a small desk fan blowing over the ceiling to keep the hot air out and blowing on the bulbs. There WILL BE another small fan at the bottom blowing up towards the computer fan to keep the plants air fresh. I'll use some Co2 cans and put it in there every Rating: 5
