Polytunnels are fantastic for extending the growing season and providing a controlled environment for your plants or livestock. However, regulating the temperature within your polytunnel is key to maintaining healthy crops and comfortable conditions. Here’s a guide to managing polytunnel temperatures effectively, with tips on positioning, tools, and winter strategies.
What Temperature Should Your Polytunnel Be?
The ideal temperature for your polytunnel depends on what you’re growing or housing. Most plants thrive in a range of 20-25°C during the day and no lower than 10°C at night. Monitoring the temperature regularly is crucial to avoid extremes that could damage crops.
For accurate monitoring, consider using a digital thermometer or a temperature and humidity meter. These tools will give you a clear idea of what’s happening inside your polytunnel, allowing you to make adjustments as needed.
How to Position Your Polytunnel for Optimum Sun/Temperature
Positioning your polytunnel correctly can make a significant difference to its temperature regulation. Here are some tips:
- Orientation: In cooler climates, position the polytunnel with its length running east to west to maximise sunlight exposure. In warmer climates, a north-to-south orientation may help avoid overheating.
- Avoid Shade: Place your polytunnel away from large trees or buildings that could block sunlight, especially during the winter months.
- Wind Protection: While you want sun exposure, shielding your polytunnel from harsh winds can prevent heat loss and damage. A natural windbreak, such as a hedge, or a purpose-built shelter works well.
What Can You Use to Automate the Temperature of Your Polytunnel?
Automation can save you time and ensure consistent conditions inside your polytunnel. Here are some tools to consider:
- Side Vent Kit: Our Side Vent Kit is perfect for improving ventilation. It allows you to regulate airflow easily, reducing the risk of overheating during the summer months.
- Polytunnel Fans: A Garden Greenhouse Polytunnel Fan or a Polytunnel Extraction Fan helps circulate air, preventing hotspots and maintaining an even temperature.
- Heating Mats: For consistent root zone temperatures, especially in cooler months, try the BioGreen Sahara Heating Mat.
- Heaters: Our Elite Plus Fan Heater (2.7kW), Levant Plus Electric Heater (1.8kW), and Shilton Gas Heaters are excellent options for maintaining warmth during colder periods.
How to Manage Your Polytunnel Temperature in Winter
Winter brings challenges, but with the right preparation, your polytunnel can continue to thrive:
- Insulation: Add bubble wrap or thermal fleece to the interior to retain heat. Make sure it’s securely attached but doesn’t block ventilation.
- Heating: Use a reliable heater like the Shilton Gas Heater or Levant Plus Electric Heater to keep temperatures above freezing. For more targeted warmth, the BioGreen Sahara Heating Mat is a great option.
- Ventilation: Even in winter, good airflow is essential. Use the Side Vent Kit or a fan to reduce condensation and prevent mould.
