Optimal Greenhouse Temperature for Year-Round Growing. Maintaining the ideal temperature in a greenhouse is crucial for promoting healthy plant growth and maximizing yield. The optimal temperature can vary based on the types of plants grown and the local climate, but generally, there are recommended temperature ranges that can help ensure a productive greenhouse environment throughout the year.

General Temperature Guidelines

  1. Daytime Temperatures:
    • Optimal Range: 70-80°F (21-27°C)
    • This range encourages photosynthesis and healthy growth. Higher temperatures can cause stress and inhibit growth, while lower temperatures may slow down plant development.
  2. Nighttime Temperatures:
    • Optimal Range: 60-65°F (16-18°C)
    • Cooler nighttime temperatures help plants recover from the heat of the day and reduce the risk of overheating. However, temperatures should not drop too low, as this can slow growth and increase the risk of disease.

Seasonal Adjustments

  1. Winter:
    • Daytime: Aim for 65-70°F (18-21°C)
    • Nighttime: Maintain around 50-55°F (10-13°C)
    • During winter, maintaining these temperatures can be challenging. Using supplemental heating systems, such as propane or electric heaters, can help achieve the necessary warmth.
  2. Summer:
    • Daytime: Keep temperatures between 75-85°F (24-29°C)
    • Nighttime: Aim for 65-70°F (18-21°C)
    • In the summer, overheating can be a significant issue. Utilizing shade cloths, ventilation systems, and evaporative cooling can help manage high temperatures.

Humidity and Ventilation

Maintaining proper humidity levels is also crucial. Ideal relative humidity for most greenhouse plants ranges between 50-70%. Good ventilation helps control both temperature and humidity, preventing mold and mildew growth. Using fans, vents, and louvers ensures adequate air circulation.

Specialized Considerations

Different plants may have specific temperature requirements. For example:

  • Tropical plants: Prefer temperatures closer to the higher end of the general ranges.
  • Cool-season crops: Such as lettuce and spinach, thrive at the lower end of the temperature spectrum.

Monitoring and Automation

Investing in a reliable thermostat and monitoring system can help maintain the ideal greenhouse environment. Automated systems for heating, cooling, and ventilation can adjust conditions dynamically, ensuring optimal growth conditions with minimal manual intervention.


Consistently maintaining the recommended temperature ranges in a greenhouse ensures healthy, robust plant growth year-round. Adjusting for seasonal variations and using appropriate climate control measures can help achieve this goal, leading to a productive and thriving greenhouse environment.
