A greenhouse is designed to provide a controlled environment where your plants can thrive year-round. However, maintaining optimal temperatures can be a challenge, especially during colder months. If your greenhouse is getting too cold, it’s important to take action quickly to protect your plants. Here are some effective strategies to correct cold temperatures in your greenhouse.
How to Correct Cold Temperature in Your Greenhouse
1. Insulate Your Greenhouse
One of the easiest ways to retain heat in your greenhouse is to improve insulation. Consider the following:
- Add bubble wrap: Cover windows and walls with horticultural bubble wrap to reduce heat loss.
- Seal gaps: Check for drafts and seal any cracks or gaps with weatherstripping or caulk.
- Use thermal screens: Install thermal curtains or screens to retain heat at night.
2. Install a Heater
Heating systems can be a reliable way to combat cold temperatures. Options include:
- Electric heaters: Ideal for small to medium-sized greenhouses.
- Propane or gas heaters: A cost-effective option for larger spaces.
- Soil heating cables: Keep roots warm by running heating cables under the soil.
3. Use Heat-Absorbing Materials
Materials that absorb and release heat can help maintain stable temperatures. Try:
- Water barrels: Place large barrels of water around the greenhouse. They absorb heat during the day and release it at night.
- Stone or concrete flooring: These materials retain warmth and can help moderate nighttime temperatures.
4. Improve Ventilation Control
Good ventilation is essential, but excessive airflow can contribute to heat loss in winter. To balance ventilation:
- Close vents at night: Prevent warm air from escaping after sundown.
- Use automatic vent openers: These devices can help manage airflow based on the temperature.
5. Use Thermal Blankets for Plants
For particularly sensitive plants, consider additional layers of protection:
- Fleece or thermal covers: Drape lightweight covers over plants at night.
- Cold frames within the greenhouse: Create an extra layer of protection for plants by using mini cold frames or cloches.
6. Monitor and Adjust Regularly
Keep an eye on your greenhouse environment to ensure it stays within the optimal temperature range for your plants:
- Thermometers: Place thermometers at different levels to monitor temperature variations.
- Hygrometers: Keep an eye on humidity levels, as high humidity can make the air feel colder.
