I would like to run a 400 watt hps without the cool tube. My closet is like 7 to 8 sqf. I was going to by to inline 6" booster fans each 230 cfm. One I'm going to put facing in the closet sucking air from my bedroom which is normally pretty cold with my window unit ac on. Then one in the ceiling sucking hot air our to the attic. Would this keep temps low enough. Thanks for any input
