I have read conflicting opinions on heat for a leopard tortoise... is this correct?? I have a brightsun uv/heat bulb 32 degrees celcius, on for 12-13 hours a day off at night,,, I ahve a ceramic on a thermostate 26 celcius (80f) , this stays on at night,, Is that too hot for night heat?? Then I am confused about the humidity,,, some people say 80 percent some say 50 percent.....
