Extend your growing season. This handcrafted cedar cold frame is built in our Woodward, Oklahoma shop from vertical 1x6 cedar siding with a sloped, hinged twin-wall polycarbonate lid.

- Designed to sit directly on our 33-inch Tall Raised Garden Bed — same 48 × 18 in footprint, made to go hand in hand.
- Solid stained cedar, built to match our greenhouses
- Hinged lid for easy access
- Bayliss MK7 Triple Spring automatic vent opener included as standard
- Ships flat-pack: four wall panels plus lid; assembles in about 15 minutes with a drill
- Assembly instructions included
Set it with the slope facing south and grow more months of the year.
