The Importance of Polytunnel Covers

 


For those tending smaller garden plots, standard polytunnel covers will suffice, while larger commercial operations require enhanced protection and ideal micro-climate solutions of heavy-duty covers. Standard covers are typically clear or opaque and are well-suited for small polytunnels and larger domestic garden purposes. These covers are ideal for those with limited space wishing to extend the growing season and shield their plants or crops from frost, pests, moderate weather conditions and the luxury of being in a sheltered environment. Their clear transparency allows ample sunlight to be spread, providing a basic level of insulation. Their cost-effectiveness and ease of installation make them a more than popular choice for keen, casual or new gardeners on their green-fingered gardening enjoyment.

 

Heavy-Duty Covers for Commercial Polytunnels

At the business end of the cultivation spectrum, commercial growers require high-grade polytunnel covers that can withstand the harshness of intensive farming and commercial environments. The demands placed on commercial polytunnels are substantial as they must endure prolonged exposure to an open-air environment, deal with harsh weather patterns, provide a stable environment for a variety of crops, and resist the wear and tear of working operations. Heavy-duty covers are manufactured with these needs and cultivation requirements in mind. They are thicker, stronger, and more durable often incorporating double and triple layers that provide quality insulation and can protect against harmful UV rays. With warranties extending up to 8 to 10 years, these durable covers cost more but are a long-term investment, reducing the need for regular replacement, reducing repairs, and offering a reliable year-round growing environment.

 

Specially Manufactured Covers

The technology behind manufactured heavy-duty polytunnel covers also includes options to combat specific challenges and requirements such as fungus and mould growth, anti-fog, anti-drip and thermic covers, for example, prevent condensation from accumulating and dripping onto plants, which can lead to mould and other diseases. For growers in warmer climates, UV-stabilized covers protect sensitive crops from the potentially damaging effects of intense sunlight and UV rays, while for cooler regions of the UK, thermic covers have better insulation properties to retain heat, crucial for certain crops and energy efficiency, ensuring valuable cost savings.

The choice of cover colour is not just an aesthetic one, they serve functional purposes by influencing the microclimate within the polytunnel. Clear covers are excellent for maximum sunlight penetration, while green, mixed or darker covers reduce light for crops that prefer lower light levels. The colour of the cover is specifically tailored to allow optimal light and temperature requirements of the crop, contributing to healthy and abundant growth.

 

Cover Solutions for Niche Markets

For niche market producers, polytunnels and their covers must cater to various crop types that may require unique and individual conditions. Heavy-duty covers can include added features such as fitted netting or shading for protection, or be part of a broader manual or automated system that includes controlled ventilation, temperature, and irrigation systems to feed and protect valuable crops.

Selecting the right types of polytunnel covers is a decision that impacts the productivity and efficiency of all horticultural and agricultural operations. While many of the standard covers meet the demands of most small-scale domestic gardeners, heavy-duty covers are indispensable for commercial, niche, and selective growers. Robust, durable covers not only protect against harsh environmental factors but also enhance the growing and protection conditions, ultimately contributing to the success and profitability of all types of cultivation operations. For businesses aiming to cultivate a wider range of crops on a commercial scale, investing in the right heavy-duty polytunnel covers is a necessity. Specialist covers can also offer many other useful options to farmers and growers alike.
