Polytunnel Greenhouses

A polytunnel greenhouse is a type of greenhouse made of polythene (a type of plastic) and designed to create a controlled environment for growing plants. It protects plants from frost and extreme weather, allowing you to grow crops earlier in spring and later into autumn. It also shields plants from pests and diseases, and allows you to control the climate for your plants.

We have a wide variety of designs, including different sizes and shapes, to suit your needs. We have compact models for a small garden and larger greenhouses for extensive growing! Don’t know where to start? Our beginner’s guide to greenhouse growing can help.

Benefits of Polytunnel Greenhouses

One of the main advantages of having a polytunnel greenhouse is that you can grow your plants and garden all year long. Polytunnels allow you to extend the growing season and grow a variety of plants even during the colder months by keeping them warmer and shielding them from harsh weather.

They guard against pests, diseases, and extreme weather conditions, giving your plants a better chance to flourish. They are also versatile and cost-effective. Polytunnels are generally more affordable and easier to set up than traditional greenhouses. And you can grow just about anything, from vegetables and herbs to nurturing flowers and fruit trees.

Optimal Growing Conditions

Our polytunnel greenhouses are designed to provide the perfect conditions for growing your plants. Whatever you are passionate about, they can create optimal conditions, leading to healthier plants and higher yields.

Ample Sunlight

The transparent polythene cover of a polytunnel greenhouse allows plenty of sunlight to reach your plants. This helps plants photosynthesize effectively, promoting strong growth and vibrant blooms.

Controlled Humidity

Humidity levels can be easily managed inside a polytunnel. The greenhouse's structure and design help retain moisture, reducing the need for frequent watering. This creates a stable environment that prevents plants from drying out or becoming waterlogged.

Temperature Regulation

Polytunnels trap heat, keeping the temperature inside warmer than the outside environment. This is especially useful during cooler months. Polytunnels allow you to extend the growing season and cultivate plants that require a stable, warm climate.

Protection from Pests and Diseases

The polythene cover acts as a barrier against pests, such as insects and animals. It helps reduce the risk of diseases by keeping harmful elements away from your plants, creating a cleaner, safer environment for healthy plant development.

Protection from Harsh Weather

Polytunnels shield plants from harsh weather conditions, such as heavy rain, strong winds, and frost. They prevent these elements from directly impacting your plants, reducing the risk of waterlogging, minimising the effects of strong winds, and trapping heat to keep your plants warm and protected from frost.

FAQs

Is a polytunnel better than a greenhouse?

Both greenhouses and polytunnels are great options depending on an individual's needs. Greenhouses are considered more aesthetically pleasing and ideal for a more permanent setup but are more costly.

Polytunnels, on the other hand, are more affordable and more practical for many gardens. They are a flexible option for extending the growing season and protecting plants from the elements, and are lightweight enough to be moved when the time comes, making them perfect for renters!
