Cold Frame Greenhouses

Wooden and Polycarbonate Cold Frames with Openable Lids from £39

Our cold frames give seedlings and young plants a low, sheltered spot to harden off and grow on, with wooden and polycarbonate-glazed designs that hold warmth and keep frost off. Most feature an openable or lift-up lid for easy access and ventilation, and several include tiered shelves for extra growing space. Prices start from £39.

About Cold Frame Greenhouses

A cold frame is the traditional way to protect seedlings, harden off young plants, and extend the season at ground level, without the footprint of a full greenhouse. Polycarbonate glazing holds heat while letting light through, and the openable lid lets you vent on warm days or close up against frost overnight. For taller growing spaces, see our Mini Greenhouses collection, and for permanent structures our Heavy Duty Greenhouses range.
