My CFL experience: I was using a 95w CFL for seedlings and it was fine...it was in a hydrofarms reflector hood Temps wer about 75. My plan was to put a total of three 125w CFL's in for vegging and switch to 3 x 150w for flowering. When I put all three 125's in the closet and it got hot as hell and even with a Vortex exhaust and a Dayton intake fan and the temps are still pushing 90 degrees! So I am bagging the ultra high output CFL's and I just ordered a cool tube for a 400w HID and a Hydro Hut. I don't think all the ducting I had to do to make the closet work helped matters but hopefully a switch to the hut/cooltube will be better.

I have seen some amazing grows on this site with several smaller (23w - 65w)cfl's and I figured more is better but my experience is that with the big bulbs comes big bulb heat. The 95w was fairly cool and I know I've seen a couple people using 105w and not complaining about heat, but the 125's were pretty toasty and I can only guess what the 150's are like!
