To deal with that I have a large (300 gallons) tub of water as a heat sink; also, the greenhouse is attached to the south side of the house. In any case, it only goes down to freezing but not below, except near the glass. For you I would think a greater concern would too little light for growth, bad for geophytes but no problem for summer-growering winter-bloomers like camellia and cymbidium. A fair number of the species I describe fall into this category. I hope that helps, and I'll be interested in further thoughts.

My unheated greenhouse manages to keep itself frost-free but if the sun does come out, the temperature may go up only a degree or two.
