Neal, I've only started growing orchids the last few months, so haven't had to worry about winter yet. Most of mine I think will be OK in the southwest window where they are now. I do have some humidity trays and will use a fogger part of the time in the winter to add more humidity. I turn the heat down to about 55-60 at night and then up to around 70 during the day in the winter. The 3 cyms I have will stay outside as long as I can get by with it, them may have to move them down to the basement at nights. I'm very much at the bottom of the earning curve right now. Just glad to have some in bloom.
