Hello all, I'm a little stumped on this one. Ill be running a 400 watt hps cool tube in a 4x4x6.5 tent. Would it be better to run filter to light tube to fan and exhaust or seperate the light and filter and run an intake line up to the light and use a seperate fan/filter setup. This way I would have to buy 2 inline fans. One for the light and another for the filter. Will the room stay cool enough with it all hooked together?? Seems more efficiant this way. And what size fan or fans should I get. The temp outside the room will stay around 70-75. Thanx all. PS-I can run an intake line from my central AC if I had to. There's a floor vent right next to the tent.
