Alrighty so I've got two BCIs, (Only a couple months old but I want something to fit them as adults) and a sub adult BP. Instead of having three separate tanks taking up tons of space, I want to build (With the help of my wonderfully helpful daddy ) a snake condo, so to speak. I was thinking each area would be 1x2x4 approx.

So here's my question. dad's a carpenter, and has lots of wood, but aside from cedar and pine, which I know are no nos, what woods can or can't I use? Also, how would you suggest treating the wood so that the heat and humidity doesn't cause the cage to grow lovely healthy mold?

Also, glass or plexiglass for the doors? I've got access to both.
