A few people suggested getting a RHP spanning the entire cage and setting it to 84 and this was what pro heat sent me so I was planning on sticking with that and wasn't sure if 2/3 is enough to do that but seems to be my only option they suggested if he was having issues with heat just place a tile under the cool hide. He's only 174 g so small and I know I can't use the entire cage because that will stress him a lot (it's an animal plastics t8). I did inform them of the divider.
