Extend your growing season with the Cedar Cold Frame 4x2 ft, designed with the same craftsmanship and durability as the renowned Alton Evolution Greenhouse range. Perfect for gardeners seeking premium quality, this cold frame combines beauty, functionality, and versatility to protect and nurture your plants year-round.

Optional Boarding Kit

You can also add the cedar paneling kit for your cold frame, this consists of a full set of boards for all around the cold frame, all made from quality western red cedar. They can give a cozier area for the plants as the wood insulates, as well as having an attractive appearance. They will reduce light to your plants. Luckily, when you add a boarding kit, it is fully flexible. You can just put some of the boards in and leave some sections with just glass in or you can remove the boards and just have all glass. The way that this works in practice is that the capping holds the glass in and also holds the boards in in a similar way (so to change to boards you need to remove the glass and insert the boards) which is done fairly easily by simply unscrewing the capping and swapping over.

If you are adding the boarding kit then you should choose the cedar capping model as you can't use aluminum capping with the boarding kit.
