Building a wooden terrarium cabinet

Funny you put this post up. I'm thinking of using an old wood and glass display case. I'm gonna use some kind of sealant to make it waterproof. When I get going on it I'll let you know if it holds out.

 

You might want to read about plywood aquariums. There are lots of good info. I make water catch trays in the grow tents with plywood and lumbers. First, I used elastomeric paint (frequently used for roof). It lasted 4 years or so, but the paint started to peel. Now I'm trying Dry-lok, but I'm using plastic sheets (the ones used for vapor barriers) on it, so the wood doesn't touch water much. It would definitely better with the kind of paint which plywood aquarium people use.
