My room is starting to get really hot, and I'm currently trying to set up a tank so that I can bring in a BP! But I'm a bit concerned about the indoor temperature right now. We don't have air conditioning but I can kind of just live with it especially since I'm not really around during the day very much. I figure that when it gets too hot, I can turn the UTH off. Even the instructions say to turn off the UTH when the room temperature gets above 80F.

...But when that happens, what do you do in order to create an actual gradient of temperature in the glass tank?

Thanks!
