yes i have a thermostat, but its useless in this case because the room tempreture its 33C and it will get hotter here so the UTH will always be off anyways, too much heat in malta during summer. The problem is that all The vivarium will be 33 or more, the maximum tempreture that it gets in malta is 40Degrees Celcius, i currently don't afford and aircondition but im gonna install one soon, so i will have to let it run the whole day for my snake? cause electricity is very expensive here so other solutions might be better.
