What bark and moss for phals?

[Andi]

I need to do some repotting and would like to know what bark is recommended and what bark to avoid.

Also, I'm going to experiment. I'm into aquariums with live plants. I would like to try mounting a phal or two to a piece of wood for wicking water from the tank up. Again, I know not all woods are phal friendly. What to avoid, what may work and what type of moss would be good to include in the mounting?

Wouldn't you know I was unable to find the pic I had showing the concept.
