I am wanting to build a rack. A need to make a rack that can hold both juv. and adult tubs. How would I go about doing that? Is it even possible because I haven't found anything that would work and be able to run off of one thermostat. I was wanting something simple so that my hatchling, my adult, and the inbetween bps will all fit in one rack.

So any ideas or anyone know where I can find any plans?
