Im back with another question, i tried to search but it was hard to understand. where should I place my acu-rite thermometer, the one from wal-mart with indoor/outdoor/humidty. I think some said to put the unit on the cold side, and run the wire probe under the substrate to the warm side of the tank. Should I put the unit on the cold side, against a wall (inside tank) or just lay it on the substrate? And should I put the probe on top of the substrate(right next to the hide box? inside the hidebox?). or have it stuck to the glass(under all the substrate, reptibark) right above the UTH? Here is a picture of the setup but I have changed it around a bit. the lamp is in the middle of the tank and so is the water bowl, and I have another hide box on the left side (cool side) of the tank.
