Lol. Just make sure you put the UTH outside the glass. I just helped someone and the UTH was stuck on the floor on the inside of the enclosure.

Make sure you can control the heat source. If you use a basic heat mat pick up a dimmer from home depot (i believe Lutron makes them) or a thermostat. If your room temps stay steady you wont have to fiddle with it too much. Once you get it dialed in dont mess with it too much (til the seasons change) because the snake will nestle down into the substrate to get the comfortable temp they desire. So if they dug down in the substrate and they're content, if you jack up the temps again they have to adjust again. ot too much of a big deal though.

Make sure you place the warm side hide over the uth.
