My new grow closet (lotta work went into it). Without the vortex fan on is running a temp of 87 degrees and a hummidity of 24%. If I I turn the vortex fan on (reverse flow/negative pressure) I can get the closet temps down to 80-81 degrees and 28-31% hummidity. I have the option of cutting vent panel holes down into the basement. The cooler basement air could then be drawn by the vortex up thru the closet and out by the vent system into the attic and out. It would be a crap shoot how much lower the temps would be, but I would be getting cooler air from the basement as well as more humid air. Any ideas ???????????
