YMX-06 heavy-duty cold frame on a raised bed
Heavy-duty

Built tougher for Canadian wind and snow

YMX-06 uses a heavier frame and sturdier hardware for gardeners who want a more permanent season-extension solution on their 4×8 beds.

When properly anchored, it becomes a long-term cold frame station for your most productive bed.

FAQ

Will it handle wind and snow?

Panels are UV-stabilized PC and the frame is aluminum. Keep the lid closed in storms and clear heavy snow promptly.

How do I anchor it?

Use the included hardware; for windy sites, add garden stakes or fasten to a wooden raised bed frame.

What’s the difference between 4 mm and 6 mm?

6 mm insulates better and resists impact; 4 mm is lighter and more compact.
