Cold Vermont Morning

Chilliest morning yet…7:30am, upper teens outside, 34 degrees in the greenhouse.  No sign of frost inside the greenhouse.  I feel like I can project at this early stage in my greenhouse experience, how the orientation can affect the light and heat in the greenhouse.  I feel I can imagine how it would be warmer in there if it were oriented East/West.  I’m thinking now that since this house is North/South, I should plant my winter crop earlier than October 2nd next fall.  We shall see.
