I have some big heat issues! Here's the set up: 3 x 2.5 x 5 box, 250w hps w/reflector, 75f ambient temps 50% rh ambient. Inside the box 103f 16% rh (no plants). I have a stanley blower moded from the rear sucking air out through 4" pvc and pushing out through 6" ducting conected to 4" ducting about 5 feet down the line, then a small peice of carbon filter conected to that (doesn't restrict much air flow), then 5 more feet until it's outside. Even if I have the diy carbon fiter inside the box off or on the temps are above 100f, even 3' away from the light. there is 5, 2" passive intake holes at the bottom and a small fan blowing up at the light. HELP!
How much does the temp drop when using a cool tube? How in the hell is it so hot in there?
Any help and/or ideas would be appreciated. I'm confused, expecially when I read posts about people's lights not being very hot.
