Was wondering if anyone knows how many cfm’s I will need for a 4’x8’x80" grow tent
For future reference:
4 x 8 x 6.5 = 208 cubic feet
208\5 = 41.6
So somewhere around 40 - 45 cfm will clear the tent in 5 minutes…

My tent is this size and I use (2) 8" Infinity fans. One for intake, one for exhaust. Works like a dream.

I have a 6" infinity in mine. My grow area is cooler so it works. If it needs extra help, I have Hurricane fan to feed air in.

Totally agree with this. To add to it, things like bends in the ducting, flex pipe, filters, silencers, etc slow air flow so you might want a little more to compensate for that.

if you want a easy way, go to hydrobuilders site look up the tent size it tells you suggested lighting cfm plant number etc.
Good knowledge, thanks everyone
