Polytunnel Temperature

Temperature control in polytunnels is a key consideration for successful growing. The temperature inside the polytunnel depends on a number of factors, including the amount of carbon dioxide, sunlight, and water absorbed by the plants. The temperature will fluctuate depending on the climate, but you can reduce the temperature by using ventilation fans and adjusting watering schedules accordingly.

Adding thermal mass to a polytunnel

Adding thermal mass to your polytunnel will help regulate temperature, keeping your polytunnel warmer in the winter and cooler at night. It can also help prevent temperature extremes. Thermal mass materials absorb the sun’s heat and release it slowly at night. Some of the best materials for thermal mass are clay, bricks, and wood.

Another great way to add thermal mass to your polytunnel is to use water. Water has a high thermal mass, so placing a container of water inside the polytunnel will keep it warmer at night. If you’re growing exotic plants, though, a single polytunnel cover may not be enough to provide enough warmth. Adding thermal mass is a good way to extend the growing season and boost productivity.

Another great way to add thermal mass to a polytunnal is by using rainwater. In some cases, you can even use rainwater to water your plants. This will not only prevent frost, but will also help the water warm up gradually. Adding thermal mass to your polytunnel will help to stabilise the temperature, allowing you to make the best use of the sun’s energy.


Ventilation is an important part of managing the temperature of your polytunnel. It allows air to circulate and reduces the stress placed on plants. Good air circulation helps to control disease. Proper ventilation is essential for growing healthy, successful crops. Proper ventilation also allows the tunnel to cool down significantly at night.

It’s also important to know when to open the polytunnel doors to increase air circulation. Lack of ventilation can cause overheating, causing the plants to die. Proper ventilation also allows fresh air to enter, reducing temperature and humidity. Proper ventilation also helps to prevent common plant diseases.

Ventilation is essential to growing healthy plants, as plants are sensitive to humidity. Proper humidity control can be achieved using simple methods. You can also use humidifiers to boost humidity levels. In low-humidity climates, plants will not grow as well as they should. If you are unsure of the right humidity level for your particular crops, use a humidity-control device to ensure that you get the most out of your polytunnel.

Low eave heights

Low eave heights for polystunnel temperature are important for maintaining the temperature of plants. This is because a polytunnel allows the soil to warm up slowly. This helps the plants to grow more easily. In addition, the polytunnel keeps the air moving, which is important for plant survival. A polytunnel can be fitted with ventilation fans to maintain the required temperature. In addition, you should adjust your watering schedule according to the temperature.

High temperature is a major constraint to plant production in many regions of the world. The design of poly-tunnels influences interior temperatures, which influences the growth of plants, the length of stems, the biomass of leaves, and the nutrient uptake. To study this, researchers examined five poly-tunnels. They tested the interior temperature of a rose hybrida called ‘Peach Avalanche’, and found that lower-eave height poly-tunnels were warmer than higher-eave height poly-tunnes.

The STANDARD21 FOOT unit is the smallest unit available and the most economical. Its structure is made of large-diameter Z35 tubing and built on swagged foundation tubing. Its unclustered design and cost-effectiveness make it a favourite of thousands of growers throughout Europe. In addition, the tunnel can be fitted with any combination of vents and doors.
