There is a culture sheet available for this species from
Orchid Culture -- Charles and Margaret Baker
I can't tell you much about it other than that, but I do feel your pain. I just went through this with coelogyne usitana and finally managed to contact someone who had grown it in their home who had some wonderful advice for me. I suggest, if you see people posting pics on this, or other forums saying that they grow this species in their home, that you contact them directly if you can.
Good luck!
