I'd say most of those would do fine in a viv. The Bulbophyllum package would most probably all be viv suitable. I wouldn't put the Vanilla in a viv. Most of those need to get very large before they will bloom. I'm not familiar with the Dendrobium in a viv, but it's relatively easy to grow outside of one. I'm not at all familiar with Podochilus, so I can't make a comment on that. Andy's has one of the largest selections of plants, and they're great to work with. If you have any questions, I'd give them a call.
