Lockhartia oerstedii

[Keysguy]

Just picked up a couple of borderline experimentation plants to see if I can get them to grow in the Keys in my shadehouse.

Lockhartia oerstedii and a primary hybrid (weberbaueri x impostor) masdevallia.

Both are in sphagnum for now but they can't survive in that once I take them south. I'm thinking both mounted on a cedar shingle with just a touch of sphagnum around the roots. Will keep them mostly well shaded and under a mister that will soak them good once every morning. Then whatever Mother Nature wants to provide for water as well which will be a lot in summer and not so much over the winter (such as that is).

Not much info available out there on oerstedii culture so does this make sense or am I asking for trouble? Any better suggestions?
