a 12V isn't hard at all to wire lol, and you can buy 250mm pc fans! its awesome, they are almost completely silent and huge, what more can you ask for in a small grow room...
you never mentioned how close your lights are, with CFL's they need to be about 1-2 inches away from the plant, anything past that your losing lum's, i know this from experience.
looks like the temps got to 100's today, i lowered them down to 80, the exhaust fan was out of place. the plant looks like it took no damage, no drooping or anything, prolly just shocked it a little.
looks nice man, congrats and good job of the CFL's, im growing 1 plant with 5 CFL's and am almost done flowering, thing looks good, Cfl's do the trick :D
I even take the clippings from my plant and put it back into the soil, wont hurt anything, just make sure you know whats in it, No seeds.. and NO bugs...
