Protect your plants from frost, harsh weather and pests with this traditionally designed cold frame. Use directly on soil or on a firm surface. Adjustable bars either side of the lid hold it securely open.
Our Verdict
The best of both worlds, a solid oak frame with twin walled polycarbonate glazing on all sides. Perfect for keeping the cold frame warm. The roof light is adjustable as you’d expect, allowing fine control over temperature and gradual hardening off.
Hawthorns make a great range of cold frames; they are great looking, robust and highly functional. Being made from solid pressure treated wood they will last without the need to repeatedly apply preservatives. The solid wooden frame also acts like a radiator, storing heat during the day and releasing it slowly at night, keeping your precious seedlings warm.
