Attaching moss I used the glue method. I rather tie in any situation except for the hard to tie angles and such of certain intricate woods. Attaching moss to the core was a mistake, as it would be covered up later with other woods. Glue also initial moss adjusts slower I've seen.
This is what pretty much killed it. The emmersed part of the tree needed humidity i could not provide. If the emmersed part couldn't survive a 8hr sleep night and dries out then its a bust. I figure despite the messy startup, if i had the emmersed buces all over, it would be decently worthy of anything. I know now I could've purchased a monsoon or something else.
