Final results of high-pressure misting research in Canadian bell pepper

LetsGrow.com and MJ-Tech have concluded their two-year research on optimizing greenhouse climate control using high-pressure misting and data-driven growing techniques. The final phase of this research, conducted in a 16-hectare bell pepper greenhouse in Canada, highlights the impact of misting, ventilation adjustments, and screening strategies on crop performance. This study marks the third and final installment in the whitepaper series on this topic.

Part 3 of the whitepaper series on greenhouse climate optimization

Optimizing photosynthesis through climate control adjustments
The research was a collaboration between LetsGrow.com, a leader in Data-Driven Growing, and MJ-Tech, a specialist in high-pressure fogging systems. LetsGrow.com provided expertise in analyzing climate data and optimizing greenhouse conditions using advanced analytics, while MJ-Tech contributed its high-quality fogging systems to regulate humidity and temperature efficiently.

This study investigated how high- pressure misting and intelligent climate control impact greenhouse conditions. It evaluated the effects of misting on plant temperature, ventilation and energy screen usage while also exploring how intelligent climate control can optimize climate management and enhance crop productivity.

Key findings:

Lower plant temperatures: misting reduced plant temperatures by an average of 0.8°C to 1.2°C, creating a more favorable environment for growth.
Controlled ventilation: misting influenced ventilation strategies, reducing wind vent positions by an average of 13.1%, helping to maintain optimal climate conditions.
Seasonal screen adjustments: energy screen usage was optimized, particularly during warmer months, improving insulation and light exposure for photosynthesis.
Higher fruit weight: The average fruit weight in the misting zone was consistently higher compared to the non-misting zone, with increases observed up to 15% in certain periods. On average, misting increased fruit weight by 3.5%.

Future steps for greenhouse horticulture
The results demonstrate that combining misting technology from MJ-Tech with Intelligent Algorithms from Hoogendoorn Growth Management and data-driven climate control from LetsGrow.com significantly improves greenhouse conditions. This research provides valuable insights for growers looking to optimize their climate strategies to improve crop health and increase efficiency.
