What promotes blooming?

I like the idea of barometric pressure and will need to test- I had been
thinking it was something having to do with lightning

I can tell you for a fact that several of my Zephyranthes, Habranthus,
Crinum and Rhodophialas can tell the difference between natural rain and
anything I can come up with.  I have tried hose water, sprinklers, (both
city water) and rainwater from a barrel.  Depending on the bulb some of the
more "easy" ones respond to quantity, a few more to quality (rainwater) but
most of them stubbornly wait for the real thing- rainwater from the sky.

Size, age, temperature and timing definitely come into play  but I still
think some bulbs have other triggers.
