Well first of all don't get frustrated, get busy! The main thing you have to realize is that you will have to continuously tweak your enclosures for accuracy and proper functioning. The humidity is easy bc in tubs it will generally run higher so just add more holes to the tub. If it gets too low then tweak your substrate and add a bit more or mist or both. The ultra therm mats function in a way that the heat waves are generated to almost pulsating type of distribution. So if you measure the mat at one point it will be different at another point. That is kind of a safety feature of the ultra therms for the reptile. If there is too much of a variance then that's when you have to tweak your thermostat. Stay in peace and not in pieces. Lol.![]()
