Ok I will attach a picture when I get home U have a temperature gun to measure the surface temp. I had to set my thermostat to 100 in order to get a surface temp of like 86 degrees in my hot spot but I am scared my snake will get burnt it it moves the substrate. and I also a digital thermometer and hydrometer and that only read like 79 degrees.on my hot side. when I use the heat lamp it gets the temp up but it j screw my humidity.
