So we have decided to go ahead and use the 2600 filter, ambient room temperature is right at 77 degrees.

plants have another few weeks on veg so no strong odors as of yet..

ventilation is filter-->fan-->hood-->attic all lined up with no 90 degree bends, two 45 degree bends at the most.

Air exchange seems to be keeping up with the 600w.

:question: but my question remains, will a 440cfm fan pulling on a filter only rated at 94cfm cause odor problems or stress the fan too much? :question:

Any input is greatly appreciated!
