The top of the enclosure is a wire mesh, with a hood on top. The DHP's are set up on top of the mesh projecting down into the enclosure, and the hood goes over the top of the DHP's to keep them contained.
The surface of the objects are warming up pretty well (the tops of the caves, a log, some rocks, the substrate). It just seems like the inside of the caves aren't really warming up at all. I rearranged my humidity box (currently a plastic tupperware with spagnum moss in it) and it seems to get up to 83F at best on the inside.
I've been using both a temp gun and a Zoomed hydrometer/thermometer combo for testing the insides of the hides. I also have other sensors hooked up to a herpstat 4 measuring the overall ambient temperature and adjusting the DHP's.What are you using to take temperatures inside the hides?
