I use this thing. I just run it 5% less then what I want. My runoff dumps into the same bucket and I just toss it into the yard every 2 or 3 days. But the dehumidifier pretty much keeps the room around where I want it. Sometimes it never stops running though. I'll turn it down to 40 when everything is in flowerJP! How the hell do you control the humidity in there? Obviously the defoliation helps. I got two dehumidifiers, but won't control inside the tent. I gotta unzip the tent and blow the air directly in.
