I'm using a 150W CHE (on a 600W pulse proportional thermostat) and have two digital thermometers, the probes are just outside of the hides, but it seems as if people put the probes inside the hides? I'm getting a temp gun in a few days, will that be able to measure the temps inside the hides? Also, what materials are safe for covering a screen top on a glass (Exo Terra) vivarium as i need to rise the hot and cold side temps by around 3 and 9 degrees respectively (temps are currently 77.5F and 81.1F). I'm getting my BP in 5 days so want everything to be correct before he gets here. Thanks.
