I'm not sure. They're mostly exoterra, and I've got the little dual temp/hygro probe ones, one of the analogue hygros, and the fogger is run off a zoomed thermo/hygro unit with an auto shutoff. Only use that for humidity, have a separate unit for heat.
On the bright side of things, at some point yesterday she lost part of her head shed and at least one of the eyecaps. So hopefuly the other will come off over the next few days.
Sorry I'm such a noob about this, I'm quite good at fish and aquatic life (turtles, watersnakes, etc) keeping, just never had a ball before.
