Recently bought a BP normal from a local breeder, have it set up and wanted to ask a few questions. First I've read here in the care sheets that the humidity in the terrarium should be 50-60% and up to 70% during shedding. Breeder said 80% was ideal, I thought this was a bit high and might be harmful so i figured I would ask you all what ideal humidity should be.
Also I'm having issues keeping a temperature gradient in the enclosure. The overall temperature of the enclosure is 88 degrees but it can get up to 91 in the summer afternoons. I have two heat lamps but usually only one is on at a time and neither are facing downward toward the floor. Care sheet recommended a basking area but then also on the forums i've read that BP's don't bask that much and prefer their hides.
Solid (my BP's name) seems to be doing fine in the two weeks i've had him. He's fed twice for me no issues. Bowel movements, drinks his water and is very active when its dark, active when held, has never nipped at me. Perfect behavior I think; i just want to make sure i'm giving him what he needs.
