I just wanted to make sure that I am thinking correctly when it comes to the temperatures that we need to maintain in our cages. Am I correct in saying that the temperatures that we are looking to maintain are the temperatures at the bottom of the cage and not the ambient temperature? I am asking because I can get the temperatures on the substrate where they should be, but the ambient temperatures are always about 10 degree's cooler. Am I thinking correctly, or do I need to get me ambient temps closer to the belly heat temps?
