Hey guys, just got a new pvc enclosure from All Reptiles in Toronto and also a RHP by pro-products. But im having trouble with my setup at the moment. I was told to hot glue the Herpstat probe onto the closest wall to the RHP about 3-4 inches up. My enclosure is 4x2x1 feet. In the third picture, you can see the herpstat probe coming out of the right vent and glued down.

The issue I am having is this: the Herpstat probe is only reading 81. I left the RHP on for 3-4 hours yesterday, and the temps rose from 70-81 (on the herpstat). I had my Herpstat set to 90 but for some reason or another, the probe was in the wrong spot and the RHP kept on heating, trying to reach 90 F. I resorted to moving my thermometer probe around (i dont have a heat gun) to check temps in different spots. It was 84 on the ground just above the substrate, and I put a branch right underneath it and put the thermometer probe on top of the branch, and it read 89 after another hour.

The problem is my Herpstat probe placement.. The RHP was actually hot to the touch. As in I would put my hand on it and after 5-10 seconds I actually had to take it off because it was burning me. (I dont think this is normal? because the Pro-Products guarantees that their products cant burn snakes) I think the reason it was so hot is because the Herpstat was telling it to go to 90 F, but the probe was placed in a cooler spot where it could only reach 81. Please let me know where a better place to put the Herpstat probe would be so that I can get a better control of my heating device.
