I'm going to try and setup a grow box for a friend but I can't find a way to lower the heat. I'm using 3 cfl's, I think their equivalent to 125w's and I don't want to add an exhaust fan. I will probably put a few battery powered fan's in it or small fan's. Can I maybe cut 2 holes at each end of it will that cool it down?

Do you have a fan in there at all? The stems need movement / stimulation to strengthen .

just do computer fans dude.Dont forget to check the box the fans come in,on the back it will say there voltage rating.Look for one that say 120VAC on the back.This way u can just wire it to a normal house plug,otherwise if the voltage is different ull need a DC converter to lower the voltage that powers them

P.S. i got mine at radio shack for $14 ea.

Dont forget exhuast as much as u intake.

And if u go the battery powered route with the fans,and the battery craps out and the fan dies so will ur plants probably too.So i personal i dont think thats worth the risk

-good luck

Alright thanks man, thats what I was think with the fan's.
