Thank you both,
I like the solar gain on the heating bill concept, might be easier to sell to my husband as well!
Sand, I was just googling NC orchid shows and saw that one, I was hoping to find one closer , Ashville's out there!
I'll keep looking though. We have a couple of options, to add a greenhouse on to our screened porch, or to add a
lean-to type greenhouse off the garage. I didn't realize that squirrels like orchids, that would drive me crazy! If I
had Ursula's collection, I'de be out there with a gun!
