So I'm 99% done building my enclosure, all that's left is to head up to the local park, find some branches, and treat them before putting them in. Will attach a picture below.
The problem is, there's a 0.8cm (~5/16 in) gap between the two panes of glass. The panes have a 2" overlay if that makes any difference. Should I be worried about that? I guess I could cut a really thin strip of PVC (Probably ~0.5cm) and attach it between the panes if so with double sided tape.
