i have small rocks over a small portion of the tank on the cool side and the rest is covered in reptibark. sitting on the gravel is a plastic branch that she sits on to bask, her basking lamp is directly above it by about 6 inches. during the day i have a 65 watt day bulb in it and at night a 50 watt moonlight bulb which puts out warmth but barely any light. i consider the hottest part in her tank is where i have a reptile heating pad under the tank and once in awhile shell lay on the bark on top of it, not too much. also on the hot side i have a half log hide. on the cool side there are the small stones, her water dish, and some larger stones that she'll lay on normally after she drinks water. i'm checking temps with one thermometer hygrometer combo on the hot side and a regular thermometer on the cool side. on the hot side her temp is basically always 88 degrees and on the cool side it varies from 80-82 degrees Fahrenheit.
