Well, since March it's looking like the greenhouse temp might be lower - more like 55F. Almost everything will be happy except for the Vandaceous family and the warmer paphs. I wish I could curb my desire but I like almost all orchids. I may be able to achieve a warm spot by playing with the heating vents. Really, just wish they'd get to work on the greenhouse. This was supposed to have been started 3 months ago and it's been delay after delay. I do have to say that my collection is looking very good under the house eves. They are getting very bright shade except for sun about an hour before sundown. My small Phal. collection is inside and I guess will remain there unless I can find a warm corner of the gh.
