Polytunnel Temperature Control

Polytunnel Temperature Control

If you are growing plants in a polytunnel, you may be wondering how to control the temperature. A polytunnel can get much hotter than the outside temperature, and this can affect the growth of your crops. However, the right ventilation can help control the temperature and humidity of a polytunnel. Proper ventilation can keep it from becoming too humid or too hot, which will help your crops flourish.

Plants to grow in a polytunnel

If you have a polytunnel, you can grow fruits and vegetables even in colder climates. You can even extend the growing season when it’s too cold outside. They’re cheaper and easier to build than greenhouses, and they’re easily insulated. You can also use an irrigation system to grow crops in a polytunnel.

Polytunnels are typically elongated structures made of plastic or metallic frames. They can be built in different shapes to create microclimates for different kinds of vegetation. This will allow you to grow plants and crops that wouldn’t normally grow in your climate. They’ll also protect your crops from animals and pests.

Polytunnels come in green and white. They are durable and resistant to ultraviolet damage. They’re usually used for livestock, storage, or for growing some types of mushrooms. Prices for polytunnels vary depending on size and construction. Simpler versions can cost as low as $60.

Cost of building a polytunnel

Temperature control is a critical consideration for successful crop production. If temperatures are too high or too low, it can damage crops. Luckily, polytunnels can help maintain temperatures. They are more affordable than greenhouses, as they cost less per square meter. This means they can be used for almost any type of crop, and they’re much quicker to build than permanent structures.

However, polytunnels are not cheap and you’ll need to invest a bit of money to get a good quality one. While it’s tempting to buy a cheap model, you might not get the durability you need. To get the best value for your money, look for a high quality one from a reputable manufacturer.

Insulating properties of polythene

If you are considering installing a polytunnel to grow your own vegetables, you need to consider a number of factors, including its size, construction, and insulating properties. You should also make sure that you have a flat surface to construct the polytunnel on. Unlike greenhouses, however, polytunnels can be built on slopes or uneven ground. Moreover, they are easily adaptable and can be extended or covered with new polythene if needed.

Polytunnels can create a micro climate and prolong the growing season for crops. These polytunnels are usually constructed from double-layer polythene reinforced with nylon mesh. The reinforced polythene provides more insulation than regular polythene. However, this type of polytunnel may cost a bit more than the regular type. Also, they are not a good choice for those who are looking for a light-filled polytunnel.

Heating systems

Choosing the best heating systems for your polytunnel can be tricky, but there are plenty of options available to suit a variety of requirements. For example, you can choose an electric heater which is far safer than paraffin heaters, and it will not pollute the environment. However, this heating option requires a separate electricity supply, which can be expensive. Moreover, it will only be as green as the electricity that powers it.

You can also install a gutter system that will collect rainwater in your polytunnel and lead it directly into a water tank. These gutter systems will collect water and provide irrigation for your plants. You can also install a system on the sides of your polytunnel, which will help retain soil moisture.


Good airflow is the key to controlling the temperature of your polytunnel. A side vent or roof vent can help by generating a breeze that can lower the temperature. This is particularly useful in hotter months when temperatures are higher. Good ventilation is also crucial to avoiding common plant diseases. Knowing when to open or close your polytunnel doors is an essential part of successful plant growth.

The right ventilation for your polytunnel is crucial to the health of your crops. A polytunnel that is properly ventilated allows the air to circulate throughout the entire growing area, promoting a healthy environment for your plants. If you’re concerned about the temperature inside your polytunnel, try to keep the windows open to allow a little fresh air into the growing space.
