A friend in Mich. had a small greenhouse wood frame 2 layers of plastic sealed with batten strips with a hair dryer inside that did not heat to inflate it , as a back up a small propane heater out of a camper .
Hahaha, well I suppose as the President it would only be appropriate for you to be there :P I'll definitely try to get up there if I can. I have been to Marlow's Orchids, and I'd love to visit Bloomfield Orchids some time. Are you referring to private greenhouses or nurseries? Do I have to be a member to attend? Or can I register at the meeting?
