Cold Frames & Winter Growing
Wed · Sep 30 · 9–11 AM · Umbrello Hay Field, Lincoln, MA
A cold frame is a box with a clear lid, and it is the cheapest way to push a growing season weeks further at both ends. We look at how they work, what makes a good one, and why the old designs settled where they did.
We design first, then build — working through the details so the result is something you can copy at home without a plan from us.
