First, I can't figure out what kind of thermometer and hygrometer to get. I just know it has to be probed. Is this one okay, or is there a better one on Amazon?
Also, my snake has a Zoo Med repti-therm under tank heater on one side of his tank, and even with the thermostat cranked up it just barely seems to heat the inside glass of the tank. My substrate is only about half an inch thick there. How warm is it supposed to be? Should I tape it tight to the tank instead of just using the sticky side it came with?
Edit: I already have a therm/hygro but was informed it was not the right kind.
