So I was looking around all the websites I can find for pvc, hdpe, and any other type of sheets that would work to make a good terrarium. They're massively expensive if you want a large terrarium. So naturally my head goes to a wooden enclosure. I know that wood isn't sufficient for heat and humidity reasons, but hear me out.

If if I were to make a terrarium out of a nice wood like oak, walnut or cherry, then seal it with a Thompsons water seal or similar, let it sit and cure obviously, and then coat it with DeckCover, it seems like it would work. if you've never seen DeckCover it's pretty cool. The solid colors are an opaque, solid, thick paint-like coating.

It's made for outdoor temps and humidity obviously, and the whole project would cost ~$275 instead of ~$700. Of course my chief concern is whether or not it is safe for my boa, who seems to want to climb and have more space. Her 48x24x12 just seems small for her.

Ive talked to several very nice people who have offered to build custom terrariums for me (shout out to AKA Dave on this site). It just seems to be costing an arm and a leg for pvc or similar.

Thoughts on safety of the snake? If it's meant to be outside, surely it can handle 75 degrees and 80% humidity for years to come. But will the coating harm the snake? Idk. So many decisions when it comes to my pets homes.
