Im trying to exhuast a 2'x2'x4' Space with 2 65w cfl and 3 26w cfl, i have one 4" inline fan at 80cfm, im doing a DIY Carbon filter which fan an what cfm would be best for my filter and do i put the filter on the inside of the box and then route a dryer house out of the closet?
With perhaps another 80cfm fan? Need two fans; intake and exhaust. The exhaust is where you hook up your filter, on the outside of the grow box. Hope this helps.
A little, but when i hook up the carbon filter do i do it at the end of my dryer hose leading out the closet or somewhere else?
He'd probably be better off just running a passive intake on a box that size. CFLs aren't going to be a big heat problem, as far as venting to the rest of the house. You will just be able to vent out of the box to the room it's in. And yeah, have it at the end of your hose, pulling air.
