Money on my end isn't the issue, he just doesn't want the bill to be high as we've gotten notices on our electricity usage.
The substrate on the warm side is at 92F and the cool side is at 78F. I have 2 thermometers, one on each side but they are on the glass about 4inches above the substrate. Should they be reading these temperatures as well though or only the substrate? I just read in another threat that some keep their warm side well over 90 as long as it's not over 100. But they also say that snakes will move if they get too warm and have temperature options to choose from.
