If it were me @minitiger Id go with the cooler temps & lower r/h. My flower room pretty much always is around those temps/rh except for winter.
But I kinda have the opposite problem ambient rh% is always high pretty much. So Im trying to keep fungi out of the flower room.
90f does seem like a lot, but I did read a post on here about how we should have higher temps for running led comparative to hid.
Im not sure what the “right” answer is, but my gut would be to go with what you have. Is it possible to more humidifiers into your space?
Edit just read in your thread, you already have FIVE fecking humidifiers.
