Tips for Creating a Polytunnel

A polytunnel is a structure that creates a controlled environment for the plants or crops within and this can help to extend the growing season. It will also protect crops from harsh weather conditions.

You have to choose the right location for the polytunnel and this has to be determined based on the sunlight the location received throughout the day. There should be sufficient sunlight and it is best if the polytunnel is facing the south or south east so that maximum sun exposure can be maintained. To prevent waterlogging, the area should have a good drainage system. Low lying areas should be avoided when selecting the location as cold air can accumulate in these areas leading to differences of temperature in the tunnel. Once you have chosen a location, you have to determine the size of the polytunnel. This will depend on the types of plants you plan to grow here and any long term growing or gardening goals. Think about the available space in the location. You will have a lot of versatility with a large sized polytunnel but this also comes with more maintenance. You will need to have more resources for a larger polytunnel as well. Therefore, you need to have the right balance between functionality and size.

Choose quality construction materials to ensure

The durability of the polytunnel. Some of the materials you can use are aluminium or galvanised steel frames. These will resist rust and corrosion. To shield the polytunnel against the elements, you can use PVC or HDPE covers. Choosing quality materials will also improve the structural integrity of the polytunnel. There has to be proper ventilation so that temperature and humidity can be regulated inside the polytunnel. This can be accommodated by installing side roll up curtains or adjustable vents. In warm weather, these vents will prevent overheating. It will also reduce condensation that can lead to the growth of fungal diseases. You will be able to maintain a healthy growing environment for the plants with proper ventilation.

You need to manage the temperature inside the polytunnel carefully.

You can have a thermometer installed inside so that any variations in temperature can be monitored. In colder months, you can use thermal covers to increase insulation. You can also use shade cloth on hot days to prevent overheating of plants. To ensure a consistent level of moisture inside the polytunnel, you need to have a good irrigation system. This can be soaker hoses or drip irrigation where water will be directed to the roots of the plants. This will minimise water wastage. You need to have a timer so that you can ensure the right amount of moisture is maintained within. The soil has to be prepared carefully inside the polytunnel. You can determine the pH of the soil and its nutrient level from a soil test and you can use organic matter to improve its fertility.
