Polytunnels are a good choice for many gardening enthusiasts because they are inexpensive and easy to construct. They can be used for a variety of purposes, including growing plants. Polytunnels can be used for vegetables, fruits, or herbs. Depending on the type, they may be warm or cold.
Costs of a polytunnel
Using a polytunnel to grow food is a great way to reduce your carbon footprint. It also helps you avoid the pollution problems of mainstream agriculture. Polytunnels purify the food that you grow and consume. However, the environmental costs of a polytunnel are more related to how you use it. Using a reputable polytunnel company is crucial to avoiding ecological problems.
Polythene tunnels come in green and white colors and are highly resistant to UV damage. These tunnels are commonly used for raising livestock, storing crops, or growing certain types of mushrooms. The cost of a polytunnel varies depending on the size and material used. A small, simple polytunnel can cost up to $60.
Commercially-sized polytunnels are 16 feet wide by eight feet high and thirty-six feet long. These are relatively expensive and can cost up to $3,500, although smaller versions are considerably cheaper.
Costs of a greenhouse
A polytunnel greenhouse costs significantly less than a traditional greenhouse. It is usually made from galvanised steel hoops and is much easier to transport. It also requires less site preparation, which means a lower initial outlay. Unlike a greenhouse, polytunnels only need to be replaced with polythene every seven to ten years.
There are two main types of polytunnels available: small and large. The smaller ones are ideal for growing plants that grow well in small spaces. Larger polytunnels are suitable for larger gardens and commercial enterprises. They can accommodate more plants and offer a wider range of growing conditions.
Polytunnels are inexpensive and are a great way to cover your garden. Even a basic 2.5m x 2m polytunnel (eightft x six feet) can cost less than PS50. The cheapest greenhouses, however, can cost you more than PS200.
Material used for a polytunnel
Polytunnels are used for growing vegetables and other plants in temperate climates. They are similar to greenhouses or cloches, but have the benefit of allowing harvesting and sowing machines to operate inside. In the UK, polytunnels have revolutionised strawberry production. Other crops can be grown in polytunnels, including soft fruits. The use of foggers can reduce the difference in temperature between the inside and the outside.
A polytunnel is usually made from PVC pipe. It is a durable material that will last a long time. For larger DIY greenhouses, you can also use reclaimed PVC pipe. A polytunnel may need hand pollination of some plants.
A polytunnel may be used for growing vegetables year-round or for a limited period of time. A smaller version may be used to try it out before investing in a more durable one. However, if you plan to use your polytunnel for a long time, it is better to spend more money. The price range of a polytunnel depends on the size and material used. A small-scale polytunnel may cost just $60 while a larger version may cost as much as $800.
Temperatures in a polytunnel
The temperature in a polytunnel can increase very quickly during the day. This is due to the fact that glass or polythene cannot reflect infrared rays, so the heat builds up inside. Thankfully, it is possible to reduce this difference with proper ventilation.
A polytunnel should have a minimum temperature of 26 degrees Celsius, but on a hot day, it can reach up to 30 degrees. This can be harmful for plant growth and could hinder photosynthesis. Overheating can even kill plants.
You can lower the temperature by using a net shade net over the windows and doors. Nets can provide up to 47% shade but still let in ample ventilation. You can also install a small heater inside a polytunnel, and monitor the temperature with a digital thermometer. Alternatively, you can use a misting system or other methods to keep the temperature comfortable.
Polytunnels are also less expensive than greenhouses, and they can be set up quickly and easily. Although a polytunnel is not as versatile as a greenhouse, you can grow many crops in a polytunnel.
