I'm sorry, I meant 70 on the cool side and 90 on the warm side. I am using a Fluker's thermometer. It looks like a speedometer (not digital, it has a little needle in it). I would be able to raise or lower the temperatures on the warm side by the amount of bedding, but I don't know any ways to change the cool side temp w/out getting another heater. I, unfortunately, am lacking a humidistat, but I mist the walls 1-2 times a day and have a humidity box, which Olaf occasionaly stays in. I'm not sure if humidity would change anything, but if it does, there's the information.
