What Are the Disadvantages of Polytunnels?

What Are The Disadvantages Of Polytunnels

Polytunnels are a great option for home gardeners who want to grow more than just a few vegetables. They are cheaper and easier to install than greenhouses, and they offer protection from harsh weather. However, there are a few drawbacks to using polytunnels. These include:

Less expensive than a greenhouse

When it comes to the cost of building a greenhouse, the amount you’ll spend can vary considerably. The materials you choose and the labor required for building them will all have an impact on the cost. A concrete slab, for instance, will cost around $6 per square foot, and gravel costs around $1 per square foot. The cost of installing an irrigation system and installing a sink can add up to another $15 per square foot.

Another option, which is less expensive than a greenhouse, is a hoop house. A hoop house is a smaller greenhouse, typically made of polyethylene or plastic film. These structures require less maintenance than a greenhouse and are often easier to set up and use than a traditional greenhouse. In addition to being more affordable, a hoop house can be attached to your home, making it easier to install plumbing and electricity than on a separate plot in your yard.

Easy to install

If you’re thinking about installing a polytunnel, there are many options available. The Superdome polytunnel, for example, has many benefits, including a longer growing season and bigger crops. It is easy to install, comes with a stainless steel frame and cover, and is made of UV stable polythene. It measures 118 x 31 x 28 inches.

Easy-Build polytunnels come with aluminium doors and base rails, making it easy to fit them yourself. You can cut the components to fit and then fasten them together with steel brackets. This method eliminates mistakes and requires no carpentry skills. Doors, which open inwards or outwards, can be fitted to the polytunnel with door hardware.

Protection from harsh weather

Polytunnels are a great way to protect your crops from harsh weather. These structures provide protection from cold, damp and sunny conditions. Polytunnels are also ideal for bare-root fruit trees and shrubs. Some types of plants require special care during the winter, such as apricots and melons.

Polytunnels are available in several materials, including wood and aluminum. Wood is a good material because it is durable and long-lasting and won’t corrode. However, aluminum frames are prone to bending and breaking more easily in harsh weather. Wooden structures are also a good option because they can be long-lasting, but need to be protected from the elements.


Polytunnels are structures used to grow plants on the ground, in planters, or in pots. Originally developed during World War II, these structures have become popular for commercial and recreational purposes. Polytunnels are a great way to grow your crops without worrying about the harsh weather conditions of the outside world. These structures are made of sturdy framework covered in polythene plastic and can be attached to a home or stand alone.

Gardening enthusiasts, growers, and professionals all benefit from the versatility of polytunnels. Whether it is for growing vegetables or herbs, polytunnels are a great choice for greenhouse and garden use. A high-quality, professional polytunnel can ensure your crops remain healthy and productive.

Drought proneness

There are several ways to reduce the drought proneness of polytunnels. The first way is to improve soil health. This can be achieved by mulching and collecting rainwater. In addition, you can add more organic matter to the soil. This will make the polytunnel more drought-resistant. This is an excellent way to save money on water and improve soil quality.

The second method is to protect your polytunnel from strong winds. You should avoid placing it in areas that are prone to flooding. However, you can make it less vulnerable to strong winds by using existing barriers to block out the wind or by planting windbreak trees and shrubs nearby. However, you should do this before you start experiencing problems with the wind.

No rainwater harvesting

The first thing you need to do is work out if rainwater harvesting is suitable for your polytunnel. Fortunately, rainwater harvesting is quite simple if you have the right accessories. If you want to take advantage of the rainwater that falls on your polytunnel, you need robust gutters. These gutters will catch the water and ensure that you receive nutrient-rich water.

A water butt is the most common container for collecting rainwater. Place this at the end of the gutter. This way, any rainwater that falls will be directed into it. This will collect water that you can then use for hydrating your crops. However, it’s important not to overwater the plants because they can drown. You can use adjustable fittings to avoid overwatering. Another option is to connect a drip/spray irrigation system to an outside tap or a well.
