New Cold Frame at Clean Slate Farm

New test cold frame at Clean Slate Farm.

 

For years I’ve read about cold frames and wondered how well they extend the growing season. Well, the other day I decided to find out. While reading Eliot Coleman’s “Four Seasons Harvest” I got the idea to poke around the wood pile and see what I could use on the cheap to build a cold frame. That’s it you see in the photo above. It aint’t pretty but it’ll do for experimentation!

I made it mostly from old 2×8 and 2×6 lumber left over from when we tore the horse stall apart to rebuild it. Hinges were purchased very inexpensively and the cover, though it turned out to be a mistake, was made from heavy mil plastic used normally to seal off French doors from winter time cold. Hey, it was an experiment and though not well designed it showed cold frames are a viable way to grow cold hardy plants even in zone 5.
