I've reprogrammed the thermostat to keep the warm side at 88F with a basking tempatures of 92F.
At night the warm side stays between 75-80F the temp drops because I don't have UVA/UVB on at night.

Should I buy a heating mat for night?
I don't know what to do about the cold side, people have told me the cool side doesn't matter and the snake will regulate itself if the hot side is proper.
