im using a reptitherm uth, connected with a thermometer/probe. its a large one, much larger than then bin, so most of it isn't under the bin but is just laying there. i stick the probe on the outside of the bin right on the UTH itself. i figured that would be a better way to be sure of the temperature.

also, i have a ceramic heat emitter to control the rooms ambient temperature, it doesnt have a temperature gauge so i just use the digital thermometer and it seems to be working out pretty fine. btw, the digital thermometer i have shows the highs and lows.

after seeing him curled up next to the small plastic circular container im starting to think maybe its actually slightly too big. and a smaller one would probably be better. but im sure my heat preparations could use a little adjusting.

most of the time its about 79 degrees ambient.
