Ok I've found something else to stress myself out over.. lol
I've realised how much the temperatures vary in my small herp room. I have the space heater set to 83 degrees. I used my temp gun to measure temps on the floor on one side of the room (the heater is kind of in the middle) and it read 75 degrees. If I read a shelf up higher it ranges up to 82 degrees (the ceiling measures 84)
If I have a thermostat for a rack, how do I set it so that it doesn't freeze the bottom snakes, or cook the top ones? I can't afford a thermostat for each level at this point..
I'm stressing out because my dumerils with a RI is on the floor level.. I have two UTHs on her, but parts of the tub could be only 75 degrees.. not sure what I should do.
