Oh no, not potting soil, I do usually use shredded coconut husk, but this past time I purchased some type of substrate for lizzards and snakes that is a bit different. Little Atreyu seems to like it though

As for the thermostat issue, would the unit below (ESU electronic temperature controller) work well with a UTH ? I am short on cash right now or I would spring for the Spyder Herpstat, but this seems like it will do the job without me having to constantly adjust it (like I would have to do with a rheostat).
