After moving the humidity gauge to the warmer side it now reads 80% .. This has dropped from the 99% this morning.. The substrate is moist on the side that the plexi-glass covers(cool side) and really pretty dry on her warm side.. No pools of water or anything like that on either side. I did have a homemade humidifier hooked up, but when I seen that 99% I turned it off.. Like I said, looks like the humidity is coming down some, I'll watch it and make sure it doesn't drop to low, say below 70% during her shed though.. Ambient temp at close to center of the tank or maybe 2/3 towards warm side is right at 80..
