Forest Large Timber Cold Frame
The Forest Large Timber Cold Frame is an excellent way to help young plants transition from the warmth of a greenhouse to outdoor growing conditions. Designed to protect delicate seedlings and tender plants, it provides a sheltered environment that gradually acclimatises them before they are planted directly into your garden. By reducing exposure to sudden temperature changes, this cold frame helps minimise transplant shock and encourages stronger, healthier growth.
Its generous internal space offers plenty of room for trays, pots and young plants, making it ideal for keen gardeners looking to extend the growing season or harden off plants before planting outside.
Designed for Healthy Plant Growth
The cold frame features durable acrylic glazing, which provides excellent light transmission while offering a safer alternative to traditional glass. This allows sunlight and warmth to reach your plants while helping to maintain a protected growing environment.
Two independently opening lids make accessing your plants simple and convenient. Each lid includes a support prop, allowing you to control ventilation without fully opening the frame, making it easier to regulate temperature and airflow throughout the day.
For even better insulation and to help suppress weeds, Forest recommends placing a weed control membrane inside the base before adding compost or soil.
Built to Last
Manufactured from high-quality PEFC certified mixed softwood, this cold frame has been pressure treated to protect against rot and decay. It comes complete with a 15 Year Anti-Rot Guarantee, ensuring years of reliable outdoor performance with minimal maintenance.
Delivered flat packed with clear instructions and fixings included, the Forest Large Timber Cold Frame is straightforward to assemble and quickly ready for use.
If you're growing fruit, vegetables or herbs, it is recommended to line the base with a suitable membrane before adding soil.
