Grow box too hot. Need help

Hey guys. I have a dilema. Im growing in an 18x18x24 box, lst of course, and i have one exhaust fan at the top of it and one fan blowing on the plants. It seems really hot in there and i was wondering if all you seasoned growers could help me out a bit. By the way, im using three 200w cfls.

try to cut vent holes in the bottom of the box. my temps were around 95 - 100 in my grow box. then i cut holes the size of the top of a party cup (one on each side of the box) and my temp dropped to a solid 80 degrees. but im not using anything that high for a single CFL. my highest W CFLs are 26 watts. and i have 3 of em in there and 7 15 watt CFLs

Hope that helps man.

Trying to control heat in small boxes is hell ..ive fryed 4 plants this summer...run lights at night open box up...more and better fans..good luck

Use both fans side by side at the top for exhaust and use a passive intake. The more air going out the more heat goes with it.

Thanks a bunch guys. Im thinking ill cut some holes for intake and see what that gets me.
