Humidity!

So I hear in flowering 40-50 percent humidity is good, but then I hear 35-45, and now I'm seeing that budding does best around 50-60 percent. Can we get a few people here with some experimenting with this?

Haven't "experimented"......try to keep mine 35-40........always afraid of higher moisture, especially when buds forming. I've always read that 40% humidity is max for flowering....never read about gains due to higher levels of moisture........

I have been researching how to lower humidity in a closet since mine runs in the 70’s when lights are out. Appears there’s no simple answer. Dehumidifiers raise the temp in the closet by 10 to 20 degrees I read, so that won’t work. I’ve decided I’m just going to have to take my chances. I’m not drilling exhaust holes in the walls and ceilings like has been suggested.

Here are some vpd charts using leaf temperature subtracted from room temperature to tell you which one to use to dial in your grow. I run my dehumidifier in the lung room. For 3 tents.

This is very helpful my only question is when you say leaf temp do you just mean the temp at leaf level inside the tent for me that is far from the room temp even with LED and a 6 inch inline fan I see temps near 84 on some days.
