They said they've had success treating it like a deciduous Dendrobium and recommended an average diurnal temperature difference between day and night, and brighter light during the winter. For my conditions, it'll approach 80 during mid-day but will ease down to about 60-65 at night with higher relative humidity.
So I'm keeping it with my Den. unicum and hoping for the best- the Coelogyne is pretty established with 40ish bulbs, so hopefully it has the resilience to put up with the occasional guesswork.
With my plants I never feel comfortable with one or two sources of information- I have to read everything available and then synthesize the data. This plant is throwing a wrench into the works
I can't wait to see it bloom.
