I have my female in a 35 gal tank with 2 identical hides at either end. On the hot side I have a UTH, and a 75W infrared bulb. Her water dish is big enough for her to soak in, and its pretty much in the middle but closer to the cool side. I also have 2 digital thermometers with the probs on the hot side, and the cool side, covered by fake plants. Lastly, there's a hygrometer in the middle of the tank. (Sorry about the picture quality, the only camera I have is my phone.)
