Okay cool!
So when I get that thermometer, I put it directly inside the tank?
The substrate layer was evenly spread out when I put her in the tank for the first time. She's now managed to push it over so it's not as thick over the heating pad. I JUST took the picture a few posts above so that's how thick the substrate is currently.
For the day time, I have a 75 watt Zoo Med Repti Basking Spot Lamp bulb & for the night time, I put on a 75 watt Zilla Night Black Heat Incandescent Bulb.
