Long story short we are going out of town for a week over Christmas and I want to make it as easy as possible for our pet sitter to care for our hatchling. I worry mostly that he might turn off the MVB and forget to turn on the CHE at night, or think he did and not realize because there's no indication. I was considering getting a heat mat to stay on at all times so he only has to turn the day light on and off. Is a heat mat okay for babies? There would be approx 1.5in of coir and he never burrows in the area I'd put it. It's a 55gal wide tank with 7/8ths enclosed at the top.
