 Yes, I was thinking of using rigid foam pieces that can be fit into the 
windows as described in the book I have.  The idea of having greenhouses 
inside greenhouses - i.e., row covers or mini-greenhouses that cover the bed 
or specific plants - is one that an innovative farmer nearby has used 
successfully in his hoop house to grow greens through the winter.  The 
greenhouse will have a brick floor and black water drums to store thermal 
mass; I'm wondering if anyone has found a better material to store the water 
in, for example rectangular so there's not as much heat loss between the 
barrels?  Can the soil also act as a significant thermal mass if the 
container is deep enough?

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
