... Putting the oak frame up took many weeks of cutting and fitting and cutting some more. We wanted it to be able to withstand any snowload.
...The first winter we covered it in plastic sheeting, which we stretched out and tacked on in the middle of a blizzard.
...The plastic was not very durable.
..We replaced it with polycarbonate panels.
..The next step was build the growing boxes. It got pretty warm in there on a sunny winter day.
..We watered the soil in preparation for planting by piling it with snow that would melt on sunny days.
..Our first crops included kale and carrots.
...Then tomatoes, but their foliage flourished much better than their fruit.
+...the new kale on Oct 19.
...O.K. We're going to let the greenhouse cool off and have a rest for a few months.
