With our cold frames, you're not just buying a product but investing in the ideal environment for your plants to thrive year-round. Our commitment to quality ensures that you receive a durable and cost-effective solution for your gardening needs. Whether you're a seasoned gardener or a green-thumbed beginner, our mini greenhouses create the perfect conditions for a diverse range of fruits and vegetables, regardless of the season.
A cold frame is a transparent enclosure designed to harness sunlight and create a microclimate for plants. Bigger than a cloche, but smaller than a mini greenhouse, a cold frame extends the growing season by shielding plants from harsh weather conditions. Its versatility allows you to control temperature and humidity, providing an optimal environment for seed germination, hardening off seedlings, and nurturing robust plants throughout the year.
Cold frame gardening can help you increase your yields and explore more plant varieties, including tender plants like eggplants and chilies. Our standalone cold frames offer ample space and protection for young crops to grow, providing 33 cm of clearance at the front and 44 cm at the rear. This makes them perfect for nurturing young plants and overwintering hardy vegetables, ensuring they thrive in various weather conditions.
Maximize the potential of your cold frame by choosing the best cold frame plants. Shield alpines from excessive rain, preserving their delicate beauty. Extend the life cycle of young annuals by overwintering them. Elevate your summer harvest by cultivating heat-loving crops like eggplants, tomatoes, and chillies, utilizing the box's warmth to boost yields. Harden off tender young plants and vegetables gradually, transitioning them from indoor environments to harsher outdoor conditions over 2-3 weeks. Gain a head start on the growing season by planting early crops like spinach, radishes, or peas, taking advantage of the protective environment the cold frame offers
The most important aspect of hardening off seedlings in a cold frame is ensuring the plants can gradually acclimate to colder conditions. This typically takes 2-3 weeks, allowing the plants to adjust to temperature variations, increased sunlight, and potential wind exposure. If particularly cold temperatures are expected overnight, throw old blankets over the growhouse.
Temperature Monitoring
Regularly check and adjust the internal temperature of your cold frame to ensure it aligns with your plants' specific needs. Use a thermometer to maintain optimal growing conditions.
Ventilation
Proper airflow is key. Avoid overheating by strategically opening the cold frame on warmer days. Conversely, secure it during colder nights to retain warmth. This balance promotes a healthy environment for your plants.
Watering Strategy
Be mindful of watering frequency. Coldframes can limit natural rainfall, so a consistent watering schedule is essential. However, proper drainage should be ensured to prevent waterlogging and root issues.
Seasonal Adaptation
Tailor your cold frame gardening approach to each season. Use the frame to start seeds in spring, protect plants from summer heat, extend the growing season in autumn, and provide winter shelter for cold-tolerant crops. Adapting to seasonal nuances maximizes the benefits of your growhouse.
Our cold frame covers are crafted from high-grade aluminium and twin-wall polycarbonate sheets, which ensure long-life protection and insulation for your plants.
Our professional garden greenhouse cold frame has a polycarbonate cover and walls. This lightweight, hard-wearing material has excellent properties that meet the requirements of growing both tender and half-hardy plants:
The polycarbonate panels provide thermal insulation, maintaining a stable and warm environment for plants during colder months, ensuring their growth and survival.
The polycarbonate material effectively filters harmful UV rays, protecting the plants from potential sun damage while still allowing them to thrive under natural light.
The 16-mm-thick twin-walled polycarbonate panels allow optimal light transmission. This ensures that plants receive adequate sunlight for photosynthesis, promoting healthy growth.
The aluminium used in our cold frames boasts exceptional durability, providing a sturdy foundation for long-lasting structures. Its corrosion-resistant properties make it an ideal choice for metal cold frames, ensuring longevity in various weather conditions. Crafted with precision, our aluminium cold frames offer robust support while maintaining a sleek and lightweight design for ease of use.

Homemade cold frames are a big hit with amateur gardeners. Making your own garden frame is the ideal way to start gardening under cover, and has its advantages. On the other hand, DIY cold frames are often made of wood or glass, materials that don't offer the best properties for practical long-term use.
As well as being easy to assemble, our polycarbonate mini greenhouse will ensure that your vegetable garden grows and is protected for years to come. Our models are delivered in kit form with all the components you need for self assembly, so you're guaranteed to save time!
