Cold air from crawlspace???

T5's put off just as much heat as HIDs (actually more)...it's just spread across a larger area. He's still gonna have to cool that air somehow no matter what lights he's using. Attics commonly get up to 120f in summer, so you're gonna need some kind of active cooling to get that space down to a usable temp.

Do you already have an insulated room built in there? It's gonna be mandatory to have any chance at controlling the temps.

damn your absolutely right, i just bought 4 2' 4 bulbs to put in my closet to vg with and they warm that thing up, i have been under the impression that they dont give off any heat..

Ain't that the damn truth.

I just keep reminding myself that debt isn't as bad as prison

and living well below your means= more money=no debt

Best way is to build a super insulated room within the attic and stick a window AC into the side of it. Also get a good attic vent so that the AC exhaust and fresh air venting through the light will not make the attic crazy hot.
