Encourage Farms in Japan operates a high tech semi closed ModulAIR greenhouse developed by Van der Hoeven for year round lettuce production. The greenhouse combines advanced climate control with an automated Mobile Gutter System, creating a stable and efficient growing environment.

The ModulAIR concept provides precise control over temperature, humidity, airflow and CO₂, while enabling efficient use of energy and CO₂. The Mobile Gutter System automates crop movement and makes efficient use of the available growing area.

By integrating climate control and automated cultivation, the greenhouse supports consistent lettuce production throughout the year while reducing dependence on changing outdoor conditions.
