Ok, so I got myself some digital thermometers that also do humidity... the stupid things don't probe for the humidity though only the humidity were the display is at... I'll have to bring one back or something... ANYWAYS...

I'm currently cooling down my warm side, it was to hot, so here are the questions.

I use astroturf like stuff for the substrate and when measuring temps I want to measure belly temp correct? On the side with UTH the temp difference on the surface of the substrate and under it is VERY different. For example, I WAS using an uncontrolled UTH. Under the substrate(carpet) the temp was 113. On the surface of the carpet though, the temp was 94.

I would assume that I would measure the surface and not under it since the snake won't be going under it? What would be a good way to hide the probe wire(s) since I'll be measure the carpet surface?
