My friend had plant sat them for me (she also keeps orchids) and she told me she had them in, what she calls, a humidity chamber. She placed them in ziploc bags when she brought them back and they have lived there since. They seem happy and are growing, but I would love them outside of the bags. I mean, since being in the bags, 2 of them have bloomed. I may try plantings of them in an open loose media and see what happens.
