I also grow a Chiloschista; I do not find it to be finicky, but my humidity is really high, and it grows outside most of the time. Chicago, though?
My thoughts on *this* leafless orchid: inflorescence grows agonizingly slowly, and I'm totally stunned every time it blooms.
I have also heard that the FL ghost orchid (Polyrhiza?) is just not a good choice for home culture...unless you have a shack in the Everglades.
