i see several views but no responses. I guess i didnt actually state the question. Do you think a 250w hps would be a bit warm for a sealed cabinet that size with regular ventilation holes in the bottom and a 7 inch fan blowing out the top? Our house stays about 70 degrees and is almost constantly air conditioned. Its hot as hell in texas. If i need more, does anyone know of a system that has air passages built into the reflector for a 250w, or should I make the ol Bake-o-round cool tube?
