Wooden cold frames come in two main designs; glazed to the ground and those with solid wooden sides.
Providing your budget will stretch to it, a wooden cold frame with solid sides is better suited to the British climate. The wooden sides absorb heat during the day and then radiate it at night, helping to keep nighttime the temperatures up in both the early and late growing season. They tend to be so effective that with a bit of carefully planning you could eat home grown lettuce most of the year round
If you don’t intend to start your growing season quite so early or extend it quite so late, then the cheaper fully glazed cold frames are an excellent buy, and they look pretty good too.
With two tough polycarbonate, fully adjustable "lights" and ample growing space within it makes the perfect compliment to any garden.
But don’t just believe us, this is by far our most popular product. Its combination of good looks, keen price and functional design make it a real winner.
