I have 65 Bulbophyllums and all of them except 8 are mounted with sphagnum moss. In your bio you don't mention where you live or if you grow outdoors or indoors. A lot of what you do will depend on your environment, I am in south Florida and they love the heat and humidity and get watered everyday. What to pot them in or mount them on or what media you use will really depend on what you want, they can be done either way. I posted pictures of my bulbo setup in http://www.rv-orchidworks.com/orchid...bophylium.html so check it out for some possibilities.
