Question about humidity and temps

[monster]

Im not going to get into heat matt debates because I tend to bend the rules abit when it comes to size and coverage, but the one thing I can agree on is you should pick one source of heating and have it comeing from one direction. I would have to agree you don't want heat comeing from underneath him and from above. Could be a little to much for him. IMO you shouldn't have heat comeing from underneath at all, they burrow to cool down not to get warm. And even if the the matt is on one side underneath it will somewhat warm up all the substrate.

It can be used on the bottom, that was the method for the person who first bred horned frog. I don't even think they burrow to stay cool or warm but somewhere in between when whether isn't ideal above. But whatever way used it should provided a thermal gradient and should be controlled by a thermostat. Personally I don't like heat mats when high temperatures are needed, they're more of a background heat source or night time IMO as they don't do much to air temperature. Heat mat on the side is great if only little heat is required though.
