Should be good to go in my opinion.i.was.thinking.the.light.track.would.help.cool.so.i.could.just.use.the.4inch.right?
Clearing a room Of cfm and cooling lights are different. A real grower knows this. Step off son your giving bad info.Your area is only 44 cubic feet. So any fan 4" and up will move more than enough air. Even if the company lies about their total CFM, A 170 CFM fan should be able to do at LEAST 44 CFM I imagine. Changing the air once per minute is more than enough.
If you have the mover and no other use for it...although it's not completely necessary like Warlock mentioned, I'd say fuck it and use it if you have it anyway. You will still get a more even coverage by using it rather than not.
I run a 600w HID in a 2x4x5 tent and use a air-cooled hood with a 6" 400 CFM inline fan.2x4x51/2closet.with..600hps..how.big.of.a.fan.should.i.use?
