I got Jump Start UL-listed seedling heating mats plus their thermostats. The combo is unfortunately kinda pricey, but I didn't want a heating cable that can't even come near itself without posing a fire risk.
I put the heating mat on one side so there's a temperature gradient. Also, since I put felt pads on my THA, there's an air gap.
