I am running two growlab80l and I am currently using 2 X Vortex 4" Centrifugal 172cfm and 2 X Clip Air Fan 6". I figure I am clearing the tent every 42secs. They sit nice and sturdy right on top of the tents no problem! My temps with no ac in socal is around 76/79. Vortex makes some good ish!
Good Luck

so you think i just need a centrifugal fan that i can just place on the top exhaust vent hole and attach a freshmaker carbon scrubber? i havent run my lights in there to se what the temps skyrocket to. the freshmakers are suited for upto 950cfm or something what cfm centrifugal would you recommend for my space? with 400w of cfl and no air cooled hoods it gets hot in there really quick. im confused as to what fan will really suit my purposes. lemme explain:
growlab60 2x2x5'3
400w cfl
6" duct booster intake as well as passives
technically the growlab60 should only needs a fan with 100cfm rating to move air by the 5x rule..
however, ive added the booster intake and obviously the exhaust fan, whichever i end up getting, will not pull air and push it through the freshmaker as rated with no static pressure. thus im stuck as to what rating of centrifugal fan i should purchase... any suggestions anyone?
i seem to have made some good choices with the tent and lighting and intakes just need my exhaust problem to be fixed before i can make any of the magic happen!!!
soooo... ima pull a kiss-ass
and ask rollitup for all your guys' help!!
