Josh, I agree for the most part, but the cage is not wide enough IMO to have that ambient temp at 77 for a BCC. Now if we were talking 8,' 6' or even 4' wide I'd say no worries as there would be some "in between" areas. I provide a night drop that low, but this situation is with a Hydrofarm stat, and the warm side is barley adequate with lower 80's on the hot side I think overall temps are low for a young BCC.
The Herpstat could regulate things much better. But for now, the choice between 77 and low 80 degrees seems narrow to me.
I guess the snake will be the judge, however once you go down the regure road with a BCC, it gets dicey.
