Best method to cover foam background?

Is it best to use dry or moist cocofiber?

There will be lots of thick horizontal branches running from side to side, which is why the egg crate is in the plans for support. I don't trust silicone to hold them up by itself, and if I can find a way to make them removable it would be even better!

If mixing with Titebond III would use it dry (have not tried wet to see if will work). EcoEarth does come in a loose form dry bag, or mix a brick and let dry out. To make branches removable can use hot glue to adhere small plastic covered (to prevent oxidation and glass damage) magnets to branches and hold them in place with another magnet outside enclosure .
