active or passive air intake

[JimWelderMan]

I want to install inline fans for my closet grow that is 2'wx4'wx8'h. I purchased 2 - 6in. inline fans but I've been reading that the air intake can just be a hole twice the size of the exhaust fan. Is this a good Idea? Because I was going to use one for intake and the other for exhaust.

Thanks:JWM

if you think about it for a sec, hot air expands, so id use the larger of the ports for exhaust. also if you live in a raised or stilt home, its good to vent the heat under the house, makes it impossible to detect grow room exhaust via flir camera
