Perhaps WNeptune can
tell me some of the types you grow in your "cool room"? How many
months a year does your cool room have a winter low of 45 - 50F? This
low temperature will probably affect the bloom time of some of the
winter blooming orchids. I found that I have to bring the cymbidium
sinensis into the house once I see the spike - I just can't wait to
see the flowers!

Most of the plants I have in the cool house are Australian natives, many of
which will grow down to 34F. I also have Lycastes (about 35), a LARGE
Dendrochilum formosanum, several L anceps, Den nobiles, several Sarcochilus,
Sarcoglottis, and a number of Onc intergenerics. I wouldn't want you to think
these just limp along-most of these have received AOS awards, including
cultural awards.
I would guess the temperature in this room is at 45F at night for about 4-5
months of the year.
Currently I do not have any cymbidiums, but I would not hesitate to have
standards, and miniatures in this room. I have had no experience with the
Chinese cymbidiums.
