no not under the glass thats silly thats not right at all and if you peel off the heatpad it usually ruins it. yes you make sure the snake is not getting down on the glass of course but theyre not sand boas lol. no need for the attitude that guy, has im not here for that. a couple inches of substrate on the warm side so they wont touch the glass has always workeds for me..if not change it. what i do works just fine and always has or id say nothing. a constant 32c on the warm side and 26c on the cool side. happy snake..never skipped a meal and always a perfect shed.
It’s always heat pad then probe then glass. You sandwich the probe between the heat pad and the bottom of the enclosure.
