Growing time gained by greenhouse?
This is our first spring/year with a greenhouse. It is 15x33' and we put 3 barrels filled with water for heat retention. We are located in CT.
Can anyone wager a guess on how much time we've added to the growing season in both spring and fall? I know we were able to overwinter broccoli & spinach (which froze & re-coperated).
I know there are many variables-I was hoping for your best guessimate?
