Differences between a greenhouse and a polytunnel
A polytunnel is similar to a greenhouse but has different features. For example, it can be equipped with gutter systems and foggers, which help reduce temperature during hotter days. It also features a domed shape, which can be useful for growing crops that need a warm environment.
Polytunnels are much more cost-effective than greenhouses, particularly if you’re growing a large number of plants. They can be constructed of inexpensive polythene covers compared to glass or metal frames of greenhouses. A polytunnel can also last for 10 years or more if it’s in a sheltered location. In addition, polytunnels can be built on rough ground with little difficulty.
A polytunnel is easier to erect than a greenhouse because it doesn’t need a flat base. A greenhouse, on the other hand, needs to be positioned on a level surface. Levelling the ground can be time-consuming, but a polytunnel can be set up quickly by two people. The polytunnel can also be moved around easily, although it’s important to secure it properly.
A polytunnel also offers better air circulation than a greenhouse. It can help to prevent damp and prevent soil diseases. In addition to this, a polytunnel can be placed facing the north or south to keep out direct sunlight. Moreover, the polytunnel has doors at both ends, which help in air circulation. The two types are similar in their purpose, but have different advantages.
Costs of building a greenhouse and a polytunnel
If you want to grow your own vegetables and fruits, you might want to build a greenhouse or polytunnel. Although these structures are very effective, they do require a lot of space and energy. However, if you’re a hobby farmer or gardener, you can save money by building smaller structures. A polytunnel costs less than a greenhouse, and you don’t need planning permission to build a domestic one.
The cost of a polytunnel or greenhouse will depend on the materials and the size of the structure. Larger greenhouses can cost over $3,500, but smaller polytunnels are cheaper. A polytunnel, like a greenhouse, needs a cover that can be changed periodically. A polytunnel, however, can last for years, while a greenhouse requires a new cover every couple of years.
The cost of building a greenhouse can run as high as USD 15746, and a polytunnel can be as cheap as $50-4,000. If you’re building a polytunnel, you can use a premade greenhouse that costs $25-$35 per square foot. If your land is not completely flat, you’ll need to use an excavator. The cost of excavating land with a slight slope can be between $3 and $6 per square foot. However, it can cost up to $15 per square foot if you’re working on very hilly land with lots of trees and vegetation.
The polythene covering will let 90 percent of natural light through. It also helps diffuse light, so plants won’t shade each other. The air inside a polytunnel will also be warmer than outside air, and the temperature will not fluctuate as much.
Costs of building a polytunnel
There are several factors that need to be considered before you build a polytunnel. First, you must prepare the site for it. A level ground is essential. You must ensure that the ground is free of rocks or other obstructions. The polytunnel must be protected from the wind and weather.
The material used to construct the tunnel is very important. A polythene tunnel, which is typically green or white, is extremely resistant to UV damage. It is commonly used to grow certain plants and livestock and to store goods. The costs of polytunnels vary, depending on the materials used. For a simple structure, it can cost around $60.
Another important consideration is the location. You should place your polytunnel in a zone where the weather is milder. This will allow you to grow a wide variety of plants that you could never grow outdoors. Also, the polytunnel should be close to the tool shed and kitchen.
It is also essential to consider the size of your polytunnel. The larger the polytunnel, the more it will cost. It can range from ten to fourteen feet in width, and between 12 and eighty feet in length. Commercial polytunnels tend to be larger and cost more than domestic ones. Make sure to find a reputable company to construct your polytunnel. Although you don’t have to spend a fortune, buying quality parts and accessories is a good idea.
