Precision Greenhouse Ventilation Solutions
Achieving the perfect greenhouse climate requires a balance of temperature, humidity, and airflow. Whether managing a high tunnel or a large gutter-connect operation, these ventilation systems provide the precision needed to protect crops and maximize yield.
Built for Growers Who Can't Afford Surprises
ZoningStrategy
Use multiple zones (Low, Medium, and High fans) to prevent rapid temperature spikes or drops. Gradual adjustments are critical in cold weather to maintain a steady environment.
Humidity Compensation
Automatically trigger vents or exhaust fans when humidity reaches a specific setpoint to help prevent bud rot and mold.
Structure Protection
Optional anemometers (wind sensors) and rain sensors automatically close vents during high winds or heavy rain to protect the structure and the crops.
Temperature Difs
Use a "Dif" strategy to briefly change setpoints at specific times, such as daybreak, to effectively dump excess humidity.
Controller Comparison
From simple manual overrides to fully automatic touchscreen interfaces, these controllers manage the environment so operators can focus on their business.
