I decided to add in some cork bark tunnels but I had already roughed up some of the expanding foam behind where the tunnels will sit, so should I seal the entire back first and then add in the tunnels and expanding foam around them or should I just expanding foam around the tunnels as is? Also there are some spots on the back that the expanding foam didn’t completely cover the glass, should I fill those with foam or just fill it with the silicone and coco fiber? I was planning on doing a bit more expanding foam anyways around the cork bark on the walls and some more where the large branches come from the wall and then around the pots as well.
There are two pots on the bottom left that won’t be expanding foamed in, they are just there to wedge in the tunnel piece so it stayed still

Rough up and seal the bits where the tunnels will sit as you don’t want unsealed expending foam inside of the tunnels, it’s produces fumes very toxic to animals and humans. Once those bits are sealed you can fix the tunnels in place with more expanding foam around them and also cover any gaps still remaining. Once you finish foaming around everything you can rough up and seal the rest.
