i'm looking at a soler and palau fan that is rated at 250cfm with 6" intake/exhaust. most of the carbon filters i'm looking at are rated at 450cfm and i know that it can filter a room UP TO that size but does that matter at all having a lower rated fan. my grow space is 112cub. ft so i feel as if though the combination should work if the rating difference doesn't matter.
