There are some things you will need to do to help keep your polytunnel well ventilated. Among them are increasing the temperature and controlling humidity. You will also need to avoid snow from accumulating on the roof or on the sides of the structure.
Side vents are not necessary
When considering purchasing a polytunnel, you should ask yourself if it requires side ventilation. While most polytunnels are designed without side vents, you may need them if you live in an area with windy weather.
If you are not sure if your polytunnel needs ventilation, you should check with your local council. They will have regulations regarding the type and size of polytunnels that are allowed.
You will also want to consider the location of your polytunnel. Ideally, the structure should face north. In summer, this can help reduce the overheating of the polytunnel. This will help keep your plants happy and healthy. However, you should be aware that this type of design makes your polytunnel vulnerable to pests and mildews.
You can add a polythene blind to your polytunnel to give you more control over ventilation. This type of blind can be rolled down when it is too hot or too cold. It can be used on both the inside and outside of the tunnel.
Controlling humidity is an important aspect in growing plants in polytunnels. Having proper control of humidity can help grow crops faster, make it easier to water them, and reduce hazards associated with excess humidity.
The best way to keep humidity in your polytunnel is to properly ventilate the area. This will allow air to circulate throughout the space and provide fresh air. This will also help prevent secondary condensation.
To humidify your polytunnel, you should spray water manually. This is especially important for plastic polytunnels. You should also be careful to avoid causing any problems with algae. The presence of algae in the polytunnel can reduce the amount of light that is transmitted through the tunnel.
Aside from water, you should make sure that your polytunnel is properly vented. This will not only help in keeping the environment fresh, but it can also protect your crops from diseases.
Another way to increase the moisture in your polytunnel is by using a fan. These devices will increase the ventilation of the polytunnel and will reduce the heat in the room.
Preventing snow from accumulating on the roof and sides
There are many ways to prevent snow from accumulating on the roof and sides of your polytunnel. For one thing, there is the obvious: you need to keep it clean. This will help you retain heat and light, two things that plants need to grow.
You can also prevent it from freezing by covering the top of your polytunnel with horticultural fleece. This will help protect your crops from frost. It can be difficult to cover the entire polytunnel, however. If you are not comfortable doing this, consider buying row covers or cloches to protect individual plants.
Another way to prevent snow from accumulating on the polytunnel is to have a rainwater collection system installed. Then you can collect water, which can be used to water your crops. It is also a good idea to have a gutter system that leads directly to the water tank. This will help you avoid fungal problems.
As a result, your polytunnel is a lot less likely to be blown away by strong winds. But even if your polytunnel is not affected by the weather, there may still be some damage. If you have a heavy storm, you should be sure to clear out the polytunnel. You can use a broom or window cleaning brush to make this job easier.
Increasing the temperature
Polytunnels are structures that are used for growing crops. These can be used for both longer-term and shorter-term use. They are commonly found in horticultural production. They protect crops from intense heat and wind, and they can also extend the growing season.
Using polytunnels to grow crops can be an inexpensive option. They are available in sizes ranging from 30 to 90 feet. Depending on the construction, they can cost from $150 to $400.
In addition to protecting crops from weather, polytunnels can help extend the growing season. When temperatures rise, you can use ventilation fans to help cool off your plants. They can also be used to reduce the risk of disease and mold. If you are planning to plant vegetables in polytunnels, you will need to ensure that they are insulated properly.
Overcrowding can also cause problems. If your polytunnel is crowded, it will be harder to keep air flow and humidity levels balanced. This can also lead to diseases and other problems.
