The breeder I got him from gave me a red heat lamp and an UTH pad and said the UTH was "thermostat controlled" and said that meant it regulated itself. I wasn't given any kind of thermostat or regulation method for either source but it's still my fault for being ignorant. I'm going to get a thermostat today for precise control. Right now the hot side has stayed at 87, fluctuating to 88 once in a while, but I'm still getting a thermostat.
