If by surface temps you mean down ok the substrate, that’s what I’ve been measuring. I have the thermometer probe on the ground level. I checked the hot hide temp on there inside before he came and it was around 91 (had it set at 92 first) so turned it down one notch to have it set at 90.
The only thing I’m wondering is if it gets a lot warmer inside of his hide because it’s plastic (the cool one) Thanks for your reply!
