I am planning to move soon from the San Francisco Bay area to either
Northern California or Southern Oregon, about 2500 Elev. The
temperatures there in winter are going to be about 20 degrees lower
than here. My question is, What is the approximate cost to heat a 10 X
12 greenhouse to a 50 degree minimum in winter? If any of you folks
live in those areas l would love to get more info from you. Thanks to
all, Ernie
