I live in Southern California and alot of african tortoise owners keep their torts outside. I think those people live more inland where the temp stays warmer at night. I live near the water and the humidity is higher and the climate is cooler, even dropping to the 60's at night mid summer. I need plans on an area my torts can stay warm at night in. I'm not really interested in dimensions, just more interested in building materials and heating elements. Also looking for something that is not going to catch on fire.
Thanks
