Thanks for the link! I have to figure out what sizes to make my tubs now, and how exactly to use flexwatt. My dad is pretty handy with electrical stuff. Together we could figure it out I'm sure.
You said I could get some premade racks online? I'm sure three tubs would be fine. Even if I don't use one or two of them. It would be a whole lot easier then making my own. So if I got them over the internet with flexwatt wired and everything, all I'd have to do is install my thermomiter, hygrometer and thermostat? Sweet!
