Thanks for your answer Ray.
They don't? So they don't need any kind of "stress factor" such as a temperature drop/dry season or similar to bloom?
The Paph. villosum has six fans and has never bloomed which was one of the reasons its former owner traded it to me. The Paph. helenae also has six fans, but has never bloomed, the gratrixianum has four and has never bloomed. I figured these guys might need something more to bloom but that is not the case then.
I'll try shading them then and leave them outdoors so they can enjoy the colder temperatures and the moving air.
