You can also add the cedar panelling 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 cosier area for
the plants as the wood insulates, as well as having an attractive appearance. They will, of course, 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 (see right) 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.
