The larger snake (35") is in a 40 gallon breeder terrarium, the smaller snake (26") is in a 20 gallon terrarium. They are both heated by their own UTH and an overhead CHE. The CHE in the larger tank is 100 watts and the CHE in the smaller tank is 60 watts. I have digital instruments in the front corners of each enclosure measuring both humidity and temperature on the warm side and the cool side. The thermometer on the warm side of both enclosures is right on the floor of the enclosure while the thermometer on the cool side of both enclosures is about 1 and 1/2 inches off of the floor of the enclosure perched on top of crushed coconut substrate. I also use an infrared heat thermometer to spot check the heat in different parts of the enclosures. But I was worried that I was missing something important concerning the ambient temperature which is so often referred to in posts. Do I need to get two more thermometers??
