Risks of high humidity
Some of the main issues associated with high humidity in greenhouses include:
- Increased Risk of Diseases
High humidity creates a great environment for the growth and spread of fungal diseases, such as powdery mildew and botrytis. These diseases can damage or even destroy crops, leading to significant economic losses.
- Reduced Photosynthesis
Excessive humidity can limit photosynthesis, the process by which plants convert light energy into energy (glucose). When humidity levels are too high, it can limit the plant’s ability to take in carbon dioxide, which is essential for photosynthesis. This will decrease your production.
- Limitation of Air Circulation
High humidity will contribute to a limitation air circulation within the greenhouse. With limited air circulation the heat and moisture, can creat “hot spots” where temperatures become excessively high. This will stress plants and cause uneven growth.
- Increased Pest Activity
Some pests, such as aphids and spider mites, thrive in high humidity conditions. High humidity can lead to an increase in pest populations, which will damage plants resulting in the use of chemical pesticides.
- Quality Issues
High humidity can affect the quality of harvested crops. For example, it can lead to issues like cracked fruit, reduced flavor, and post-harvest decay in certain crops.
- Energy Costs
Maintaining high humidity levels often requires additional energy to dehumidify the air or maintain proper temperature control. This can increase energy costs for greenhouse operations.
How the high humidity can be solved?
To address high humidity in greenhouses, the are different options:
1. Reduce humidity with ventilation
Adequate ventilation systems are crucial to maintaining the airflow and humidity control within the greenhouse. Exhaust fans, roof vents, and side vents help remove excess moisture.
2. Reduce humidity with dehumidification
In certain situations, ventilation alone might not effectively control humidity levels. This is where dehumidifiers come into play, actively extracting excess moisture from the air. Multiple systems are available, each with its unique advantages.
At Horti Future, we provide expert advice on selecting the most suitable dehumidification system for your greenhouse. We understand that different scenarios call for different solutions.
When it comes to forced dehumidification, we have in-depth knowledge of the various systems, enabling us to guide you in choosing the one that aligns best with your specific needs. Our aim is to help you achieve precise humidity control within your greenhouse, ensuring optimal conditions for your crops’ growth and health.
3. Reduce humidity with temperature control
Maintaining the right temperature can help manage humidity levels. Cooling systems, screening systems, and heating systems can be used to regulate temperature and humidity.
