So I was searching through the threads and didn't really find anything. Most plans that I have seen for racks call for using melamine coated wood. The problem that I have with this is that melamine is the same stuff that was making people sick in the hurrican katrina trailors. From what I have been told, it is made from formaldihyde. Anywho, what I need is atleast 11 large containers and 6 smaller ones. I am thinking maybe 41qt unless that isn't large enough for a full grown red tail. And the 6 will be used to house African house snakes, corns, and hognoses. Here's a list of questions that I have What is the best material to use? What size tubs would be big enough for full grown red tails, corns, and BRBs? Belly heat or back heat? And does anyone know of any plans out there that can fit all of that into one rack?
