1. Cypress Mulch with a little Coconut Husk.
2. Currently using my thermometer with probe, not a stick on. Bought a faulty thermostat, returning it and buying a new one after work tomorrow.
3. Was using my thermostat that suddenly went out. So I'm manually using my thermometer with a probe.
4. Probe is currently under bedding. I read that the cool side usually takes on room temp, and it's quite hot in Wisconsin today. My room is about 83º.
**Have two thermometers with probes measuring both sides.
**Warm side is currently at 89º now.
**While I'm gone at work, I have someone checking on the temps so he is safe from getting too cool or too hot.
