I've noticed that due to the bad weather, it's raining a lot, and there's very high humidity in my greenhouse on the terrace. Is there a way to reduce it? I've heard that cat litter is supposed to help.
Hi, I wonder if the cat litter outside helps. I also think a dehumidifier doesn't make much sense. Are they autos or photos? As long as they're not in the flowering stage, I wouldn't care how high the humidity is outdoors.
