24 x 54 x 96 closet with 291 cfm fan in ceiling in a newly remodeled grow room due to replacing my HPS hooded light to an LED system. With my old system I had some cardboard above the light to help hold in the humidity so it wouldn't suck straight up to the filter but with this LED light you can't put anything above the light so my humidity sucks straight up to the point where I can have them on full blast and it doesn't really make much difference from the humidity outside of the closet. if I shut the exhaust fan off for 10 minutes at a time the humidity does get up where it needs to be.Do you think I could get a timer to shut the fan off every 15 minutes or so?will that still supply enough air to grow healthy plants? I only need this extra humidity during the first two weeks I could close the intake vent size to slow down the air flow too IDK
