 Carbon Filter Issue | |
I have two 85 cfm fans on the the intake and the exhaust of the grow box...I have not actually hooked up the carbon filter to the exhaust yet because theres no smell. I think the cfms will drop about half or more when i add the filter so that leaves me with about 35 to 40 cfms maybe.. The cfm calculator says that i need at least 40 cfms to exchange the air once every min.. I think that i should be good on this but not for sure....Tell me what u think if you want. Thanks |
