That sounds awesome. What zone are you in? We’re 5-6 here.
I have a lot better luck with lettuce this way than when I try to plant it in the spring anyway.
This year I have 3’x 28’ under cover, but I didn't get it planted as soon as I would have liked in the fall.
Winter wheat will grow at 35 degrees and above IIRC, and I don't remember for sure on the other stuff. But they make varieties of lettuce than are better for winter weather than others. They sometimes have names like “Arctic” somewhere on the package.
