Good question Ross, I do not know!
I have had it for 6 weeks and during that time alot of buds have come. I grow it in my orchid cabinet, mounted on epiweb, spraying it every morning and sometimes in the evening. Relative humidity is 70-95%. it has started growimg also so it seams to like the conditions.

Reason I ask is it seems like New Guinea stuff seems to prefer wet rather than dry (on the average). I'm always on the hunt for wet-growing minis for my orchidarium.
