You guys are great! I appreciate everyone's reply and willingness to help. To answer a couple of questions, I am using a temp gun and I have the uth side by side covering about 1/3 of the floor area (I have them stuck to the bottom with the tank on half inch risers for air flow). I do not have a humidity box but I can surely make one. I would have to move his water dish to the middle for it to fit. I will post a pic of his set up as it is right now if I can figure out how to attach one. Lol. Thank you again, everyone. 😁
