I only add humidity when RH is less than 30%
Temps here have been getting cooler and Rh has been dropping out the bottom. Temps in the tent have maintained 75-80f / 23-26c but Rh has dropped to 35-40% and I believe I can see the top of the coco drying out faster. Any reason for me to add humidity? I could put a cool mist humidifier in the tent if needed but with an extraction fan running not sure how much it would help.
