What's your source and what color? I'd recommend rinsing anyway to get rid
of the really fine stuff. If you get colored, the red can have a tremendous
amount of coloring, clay, fine silt depending on the provider. It's similiar
to sponge rock but retains less water. I use it for all vandas, aerides,
ascocendas, ascofinetias, rhynchostylis, vandafinetias, brassovola, etc; you
get the idea. In a mix; I haven't tried that yet. Let me know if you do and
what are your results! Thanks.

Anybody out there use pumice in potting mix? Wondering if it has to be
rinsed?
