I currently have 2 cages set up with Ultratherm heat pads purchased through Reptile Basics. I’m using them with the Reptile Basics pvc cages and a Herpstat 2 (redline). My ambient room temps this time of year are between 72-75F, so this is working fine for my corn snake. If I was using this for a bp, I’d use a RHP instead as that would boost ambient temps in the cage as well as provide a hot spot.
