I've recently acquired a bunch of new bulbos from a friend, and I've got plants in semi-hydro, sphagnum, bark mix, esoteric combinations, mounted, and who knows what else. I mist all my bulbos heavily every morning and water weekly more or less, depending on the season. I'm going to repot about 40 plants, and all these different mixes drive me crazy. As much as possible, I like to keep things simple and standardized. Apparently Frank Smith grows in sphagnum. My local friend and bulbo expert Jo Levy uses a bark mix. I'd love to hear from you guys as to your recommendation for a good mix for bulbos.
