The other stuff is from petco, is comes in a brick, you add water to it in a bucket and its supposed to help hold moister. I added it the second day because everything was evaporating so quickly I was having a hard time keeping it humid.
Ok, I'll pick up another hide soon. I'm currently using a small under tank heat pad dealy that came with the tank. I bought a dimmer for it so I could control the heat. I leave it at ~50% power. I have a thermometer probe in the substrate under the hide. I also use a 50 watt black bulb.
