Does it experience at least a 10 degree F temperature drop between night and day?

How about seasonal variations in temperatures?

Philip, just for clarification, who are you asking? My Bulbos get temp variation just because that is how I keep my greenhouse. Whether the temp has anything to do with flowering with Bulbos, I'm not the one to know... sorry

Asking Paul.

The temperature variation is what prompts Bulbos to spike.
