My Diplocaulobium aratriferum is doing quite well. Recently had 18 flowers, just for one day, but was spectacular. Out of the maybe 100-200 flowers of the lifetime of the plant thus far, once I had two flowers come out from one leaf base/pseudobulb.
Here is a picture of the entire plant with 18 flowers:
Below is a blow up of a couple of flowers:
I grow it in a terrarium on the cool side (50-80F) under a 4-bank of T5HOs high up in the terrarium. It gets misted every day for a couple of minutes, and then fertilized once or twice a week with K-lite RO. It sits in a ~2" clay pot with mostly roots, a bit of cocohusk filler.
Leaves are not that great, but it sure flowers. So no complaints.
Sobrofio, in my opinion, cool growers do best in cooler temperatures but they don't like warmer temperatures above 80*F. You might be able to grow it in your environment. It does seem to like a lot of moisture. Thank you for sharing your plant tropterrarium. Excellent photography!
