Title basically says it all. What would be the best method of keeping a Leopard tortoise warm at night in an open air enclosure? And could you keep him warm while he's enclosed in a hide with a top to it? Thanks.
The only way to do it is to burn lots of electricity over the tortoise. This constant desiccating electric heat will contribute to pyramiding.
Use a closed chamber instead. Then you only have to use a small amount of electricity to heat the inside of the chamber, and it will stay warm.
What if you did overtop heating but with very moist substrate. The evaporation will keep surface humidity ok?
I use MVBs and closing the enclosure could cook the poor guy. I guess there is no perfect solution but closed chamber with proper UVB/heat seems ideal.
