already on it. just two days ago i bought a UTH and a thermometer + humidity tracker. I just started spraying the cage today because the humidity in my room is constantly terrible. currently, it's at 75 degrees on the hot side, which i know is waaaay too cold, but i'm working on it getting it higher, and the humidity is at 53%.
the UTH is on the right side of the 20 gallon tank, below the water bowl. then there's a red heating lamp on the left side.
i only have one hide on the left side under the red lamp, and i know it's recommended to have one on each side. i'm planning to buy a second one asap.
and then, for substrate, i have aspen wood shavings, which i'm going to change to newspaper later this evening.
