Ok so next question, where would the temperature probe be best placed?
I currently have a temp probe measuring air temperature on the warm side, and a second temp probe measuring air temp on the cool side. But now I wonder if I should be measuring substrate temperature instead? I do have a thermostat on the heat pad, but the actual temperature the snakes will be sitting on would differ from the heat registered directly from the heat pad, so that isn't an accurate way of measuring substrate temperature.
