Thanks for the reply, Dot! I think I'll appreciate these gorgeous orchids vicariously though the photographs of others. I don't want to be buying orchids only to watch them die due to my neglect. There is no way I could provide humidity levels that high.
my humidity isn't that high (under lights in apartment), and they do okay. another grower in our club had a plant from my compot and his plant died, and he grows in a basement greenhouse with ultrasonic foggers. he may have tried to grow it too wet, when I think it is a wet/airy grower. it all boils down to which set of conditions best matches allowing some moisture for a while and then drying a bit, then moist again. just a balancing act, and with flowers like that it's worth a try!
