Prof. Samuel Fitzgerald, Ph.D.Climate control in greenhouses is directly related to plant health and production capacity. Plants require specific environmental conditions to maximize their photosynthetic performance. Hence, the temperature, humidity, amount of CO2, and the quality of light must all be controlled closely. This eliminates problems in growth while utilizing the resources in your greenhouse most effectively.
Temperature Regulation
- Maintain species-specific ranges like 22-27°C for tomatoes
- Prevent heat stress above 35°C that halts photosynthesis
- Avoid chilling damage below 10°C for tropical plants
- Use thermal screens and heaters strategically
Humidity Management
- Keep 50-70% RH for most crops
- Prevent mold with proper air circulation
- Use dehumidifiers when exceeding 80% RH
- Maintain vapor pressure deficit balance
CO2 Optimization
- Enrich to 800-1200 ppm during daylight
- Coordinate with light intensity increases
- Monitor for proper stomatal conductance
- Balance enrichment with ventilation needs
Proper climate management prevents multiple stress factors in plants. Adequate management of temperature causes blossom drop in tomatoes. Extremes in moisture will cause the spread of fungal diseases. If the level of CO2 is uneven, the efficiency of photosynthesis is decreased. Your plants will show visible distress when conditions are not within proper limits.
Automatized systems continuously provide optimal conditions. Each item of the climate parameters is monitored by sensors that are in constant operation. Controllers control ventilation, warming, and misting instantly. Climate automation yields increases of up to 40%. The control of resources increases significantly with succession and refinement.
Overcome seasonal limitations and supercharge your productivity with climate control year-round. Costs of energy will drop when controlled efficiency systems are implemented. The quality of crops will improve tenfold. Your greenhouse will feel like a predictable production environment.
