So I just got my 4x8 tent and anew 600watt. I already had a older 600watt laying around. But I was wander can I run a 4in inline fan with carbon filter in a tent that size?
I went on amazon I got 2 240 cfm booster fans there like 29 $ each but those work even 1 of those with your 4 inch would work just fine. Check this out on AMZN: LEDwholesalers GYO2402 6-Inch 240 CFM Air Duct Inline Hydroponic Booster ... http://amzn.com/B003YFADW8
A 4 inch fan like 250cfm is enough if you have cooled reflector and fresh air intake, if you dont have reflector i recommend you at least 400cfm out and 100cfm in .
Or what if I duct separately from the lights? I'll hook up the 4in inline to the filter and vent it out the side. I'll get to duck boasters and place one at the exit vent and the other at the begging vent
