Sorry for the late reply! And I've read that you're supposed to put the probe where you said to put it but wouldn't that be inefficient? Wouldn't you want to put it where the snake is most likely to be? I'm not so much questioning you as more as I'm just curious. And the humidity ranges between 50-70 depending on time of day. I keep moist towels on top to regulate it since it is a glass tank. And second question is if I do move the probe to where you recommend, how much do I need to concern myself with the ambient? Because I know ball pythons don't bask necessarily, they get most of their heat from belly heat. But I also understand that the ambient temp cant be like 70 degrees on the hot side either. Thanks for the reply again!
