Fresh Venture Farms in Ontario, Canada, has raised bell pepper production by an average of 16% over four years through targeted water quality improvements. Growers credit cavitating ultrasonic transmitters and nanobubble technology for healthier roots and higher outputs, projecting 35+ kilograms per square meter by 2025. This approach cuts costs and supports full water recycling in greenhouse operations.
Targeted Technologies Transform Irrigation Water
For over four years, Fresh Venture Farms has partnered with Ultramins to deploy USAF™ DT-100 cavitating ultrasonic transmitters, suspended under orange buoys in water ponds and silos. Last year, the farm added nanobubble technology and routine hydrogen peroxide applications to its daily supply. No other disinfection methods enter the system. These tools generate cavitation—microscopic bubbles that implode to disrupt pathogens—combined with nanobubbles that enhance oxygen delivery and peroxide stability in water.
Cost Savings and Pathogen Elimination Drive Gains
Hydrogen peroxide use has dropped more than 50%, saving $0.10 to $0.15 per square meter annually, according to Florian Locher, a key figure at the farm. Synthetic agents vanished entirely as root quality improved, slashing costs per square meter by 40 to 50%. Return on investment came in under six months. DNA sequencing from A&L Laboratories confirmed the transmitters eradicated Fusarium and Pythium in water samples, enabling 100% recycling without contamination risks.
Root Health Sustains Season-Long Production
Photos from the farm show robust, healthy roots persisting through the full growing cycle, a stark contrast to earlier issues. Locher started with transmitters in the main pond despite initial skepticism, then expanded to two for silos and five for daily water. "It streamlines irrigation, increases performance, and makes growing easier," he says. "I practically don't have to worry about my irrigation water anymore." Clean water underpins closed-loop systems common in modern greenhouses, where pathogens like Fusarium threaten yields by rotting roots.
Scalable Model for Sustainable Horticulture
Bell pepper propagation faces mounting pressure from water scarcity and disease in controlled environments. Fresh Venture Farms demonstrates how ultrasonic cavitation and nanobubbles address these without chemicals, offering a blueprint for propagators. Locher calls investment in USAF™ DT-100 units a "no-brainer," urging others to adopt them via Ultramins. As greenhouses push for efficiency amid climate challenges, such water treatments promise reliable pathogen control and resource savings at scale.
