Are you dreaming of growing vegetables so massive they break records? With a Keder Greenhouse, you can turn that ambition into reality. Let’s explore how to achieve these extraordinary results.
Why a Keder Greenhouse?
A Keder Greenhouse is engineered for peak growing performance. Its unique cladding system provides superior insulation, light diffusion, and exceptional durability, ensuring a stable environment where plants can thrive. This innovative design evenly distributes light and warmth while protecting crops from extreme weather and pests - key factors for growing record-breaking vegetables.
Proven in some of the harshest environments, including the Shetland and Orkney Islands, as well as the Falkland Islands, Keder greenhouses have demonstrated their resilience against winds exceeding 120 MPH and heavy rain, sleet, and snow. Trusted by commercial growers and expert horticulturalists across the UK, Keder Greenhouses set the standard for robust, storm-proof structures.
Steps to Grow Record-Breaking Vegetables
Choose the Right Seeds
Select high-quality seeds bred for size, such as Atlantic Giant pumpkins or Big Zac tomatoes. Platforms like GiantVegSeeds.com offer seeds from UK and world record lines.
Prepare the Soil
Start with nutrient-rich, well-draining soil. Enrich it with compost and manure to ensure your plants have the foundation they need for vigorous growth.
Control the Environment
Leverage the automated roof vents in your Keder Greenhouse to maintain ideal temperature and humidity levels. This controlled environment promotes consistent growth and reduces stress on your plants.
Feed Regularly
Use premium fertilisers tailored to large vegetable production. Organic options, such as fish emulsion or seaweed extract, are excellent choices to support robust growth.
Prune and Support
Regular pruning encourages plants to focus energy on producing larger vegetables. For heavy crops, use supports like trellises, cages, or slings to prevent damage.
Pest and Disease Management
Although Keder Greenhouses reduce the risk of pests and diseases, routine checks and organic treatments are essential for maintaining plant health.
