Kris, I have been thinking about this a little myself. I wonder about 
using some fome insulation that would swing down at night in an effort 
to hold on to a little solar gain? -Jeff

The floor will be insulated underneath (it can't be at ground level due to tree roots), and we'll do everything we can for thermal mass - water containers in front supporting the beds, and a brick paver walkway - but I'm still concerned about how cold-hardy it's going to be here in Michigan (it will only have solar heating).  At a minimum, I'd like to be able to start seeds in it in March (as opposed to in my living room)...  I would love to hear of others' experiences with small greenhouses in cold climates, and what diy modifications they might have tried to prevent the plants inside from freezing.  I'll be glad to share whatever I learn from my experiences.
