Awesome! So I would just stick the heating pads under the tubs like I do with the tanks and stack em? I am going to have a hatchling, a juvenile, and an adult sized tub. I was thinking of putting the adult on the bottom for now (after quarantine time, i just picked him up last night) and then putting the hatchling and juvy tubs on top of that. Could i just use a heating pad on the bottom of the adult tub and then have the other 2 tubs share a heating pad on the top of the adult tub? I was going to plug the pads into a power strip controlled by a dimmer.
Within the next couple months I will be building a rack but i am just trying to free up some space in the mean time.
