Bulbophyllum treschii care- anything special to keep it happy and blooming?

[Fishkeeper]

Does B. treschii require a winter rest, or any other prompting, to re-bloom? I'd love one in my 12x12x20 terrarium, even if it is a tad on the large size as terrarium inhabitants. For something that blooms like that, I can make room! And it sounds like it'll grow reasonably well in a (ventilated) terrarium. The question is whether it'll bloom for me. I could probably shorten the light period an hour or so in winter, without bothering the rest of the plants? But the whole setup is auto-misted, and will include things that do not want a drier winter, so I can't water it less.

Also, how big are these? I have a rough size estimate from pics online, but I don't have exact numbers. Does anyone have one they could measure, from leaftip to bulb base?
