Yeah, that is a good idea too, I'm sorta trying it now with valsnaria. I heard the moss works well on mesh, but then I heard it takes 2 lifetimes to fill in decently, I'm sure it depends on the plant and its care, but whatever moss balls they sell in Petsmarco hardly, if ever grow at all, at least thats what the girl that works there with the braces on told me. I'm pretty sure if I had asked her age, she would've giggled, then lifted her lil' open hand up 3 times saying" I'm this many!" so I think she knows what she's talking about
