The UTH should only have at most 1/4 inch of substrate over it. This keeps the UTH at a temp that will not harm your snake if the substrate is moved and laid on directly. Having a thick substrate you will need to keep the UTH at a high temperature so the heat can reach the top of the substrate.

Yes, you can use the lamp too. On my 40 gallon in a cold room I have a uth, che, and heat bulb.

I questioned your post because it did not seem as if you wanted to do things correctly and instead choose to do things half way which is not safe for your snake. You should have done a bit more research here and we could have helped you get things right the first time, saving you time and money.

I use Herpstat and love them.
I got the hydroform thermostat, but I'm confused, you said to put the probe between the UTH and the tank bottom on the outside?? O__o On the outside of the tank? I was gonna have it between the carpet and the substrate.

Also I want to keep using the lamp, my room temp is usually in the low or mid 70's
