That's the guy, and there are others too. I came to this because I grow in a closet as I have no other space to grow in. I had problems in my last grow with bud rot as there is no ventilation besides keeping the closet door open.
Without circulation it's problematic at night when the door is closed. I want to use a dehumidifier for my next flowering phase but as the closet is small I'm sure it will reduce my humidity to 0% which is why I'm trying to figure out if it's okay, or find some other solution.
