ditto... i think that you are gonna have some kinda major heat problems man..
cfls put off more heat/watt than HID systems.. you may have to put a fan off the 'light board' blowing across the CFL's to keep heat from building there... they are gonna be close to the tops.. i assume.. and that means the heat is gonna be closer than if you had a 250w HPS. and the HPS would have way better light penetration.. but it you are set on the CFL's just vent the board somehow and you should be fine in my opinion..

mainegrown Reviewed by mainegrown on . New Cab and Lighting Question...Redtails, DutchPimp, Bones and others chime in please Hey folks, For Christmas, I received a new cabinet. Its a utility cabinet that fits in the garage without standing out. It 72" high, 48" wide, and 22" deep and all white inside and out. Today I bought some additional CFLs and a fixture to put in it along with some T8's with fixtures. The idea is to mount the T8's vertically on each side with the CFL's mounting on a hanging platform from up above. The T8's are Phillips high color rendering, 48 inches long, 32 watts, 6500K bulbs X 4 Rating: 5
