Hello, I posted about this earlier, but I am wondering even more now.
I am planning on creating a rack for 3-4 snakes, currently, I have 2 ball pythons.

How do you set up the belly heat? What tools/materials are needed?
Could I use regular wood for the shelves? Does it have to be melamine? Or could I buy those plastic dressers that come with the already-there plastic containers needed for the snakes?
