I'm going to me raising some dubias for my ever growing T collection, but have some questions about heating first. I was thinking about getting Repti-therm heating mat and attaching that to a light dimmer (and have a thermometer to check the temps) and then control it that way, would that work? What's a good number to order? I was thinking about getting a bunch of little nymphs and then some juvies and some adults, as most of my Ts are under 2" (I have 27 of them).
