Thanks for the reply. I can see this being a great way to go for a dedicated farm, which this post is proporting to do, but I am not sure I would want a high tunnel in my yard. I am on the wild-yard side of things and have wildflowers planted along one edge of my property, a milkweed garden, etc. I like to be able to see things growing and am not sure how I would feel about the visual block. I guess you could make one with more long-term transparent sides, but that would cost more $$.
As it is, we often have too large of yeilds when our four 4x8 raised beds really get going. Our issue isn't yeilds, it's the narrow width of peek yeild along with a combination of what we grow (not shelf stable) and storage systems (the whole pick early, store so it won't ripen, and ripen on demand system).
