Well there's water crystals in there, and I just put a jar of water in there. Humidity is at 20%... With the heat pad I could keep the humidity at 40+ but the heat pad got way too hot. The CHE is perfect heat wise. But now the humidity sucks. Havent lost any females. Lost 3 of my 10 males, and about 5 nymphs. I've only had this colony for a week...I worry that if I don't figure this stuff out ASAP, I'm gonna lose em all. geez, I fix one problem, then another one develops. I live in Michigan for crying out loud. The humidity here is always high. Wtf?
