the library, too, but it’s
too late for that now). I thought about it. And I looked around some
more. I spent enough time looking around that Jenny gave up on me, and
frost overtook the garden, but I hadn’t given up.
I didn’t find one design that had everything I wanted, but I found two
that were close:
Deluxe Four-Season Cold Frame – from Mother Earth News
Frame Poject (pdf) from Garden Gate Magazine
“Mother’s” cold frame is well-insulated, and the article explains the
lessons of experience behind its design, but the how-to instructions
were not specific enough for me. That’s what led me to the Garden Gate
design – I think I can build it from the materials list and picture
they provided. And I can always add extra insulation or a buried
extension later – so it will be more like Mother’s design, eventually.
I’ve gathered (almost) all the parts for my cold frame (with a couple
of splinters to show for it), but the most important part is still
missing: the clear top. I’m looking for a local source for structured
polycarbonate sheeting, but haven’t found it yet.
