No I was advised to adjust temp by raising or lowering his lamp so that the temp is where it is at full power rather than trust a thermostat that could possibly malfunction, I do have a thermostat in my BP tank as the set up is different and I’m not able to adjust the lamp heights, but I run the lamps only in the day on timers on both and just the pads and ceramic heaters at night so both tanks cool down at night as it would in there natural habitat no?? Both have heat pads under a hide that reads 85-86 in the boa hide at night, the BP tank has a covered top and holds heat better so the warm side stays around 85 overnight and her hide doesn’t drop below 90 These temperatures I got from a temp gun.
