I may try it on top of the hide that is under the RHP. The UTH and RHP are directly over each other. I will try both on the hide or under the substrate and see which keeps the temps best. I have a temp gun so I can keep an eye on it.

I plan to use one thermostat per cage unless that just will not work. I will be setting up a second cage soon (will have its own thermostat) so looking for what works best.

Is there no one else out there that has both belly heat and a RHP?
