Barb and Gena work on building the cold frame. We struggled with using pressure treated wood, but due to expense, time and ease, we finally weakened. Our other options were concrete or untreated wood. One was very expensive; the other would rot too quickly. To protect the vegetables, the inside of the planting area is lined with black plastic (reused) and then insulation. None of the chemicals used to treat the wood should find their way into the vegetable growing areas.
Once again, tradeoffs! Avoiding the negatives of our culture is an ongoing challenge -- a challenge we fail to meet all too often, despite our commitment to living lightly on the earth. The market place offers such a vast array of choices. Although it's not easy to shrug our shoulders and go for the modern solution, we do submit to the ease of doing so (or need?) on occasion.
