• Minimizing temperature and humidity differences within growing racks
• Achieving airflow above 0.5 m/s over leafy greens
• Reducing stagnant air between growing racks

Stagnant air between racks

Whole-room airflow alone could not reach deep into multiple rows of crops. Heat and humid air remained around the leaves, creating location-dependent temperature, humidity and growth differences.

Insufficient airflow above leafy greens

Consistent airflow supports transpiration and heat removal. Low velocity allowed air to stagnate above the crops, so achieving at least 0.5 m/s directly above the vegetables was a key requirement.

Risk of tip burn

Persistent stagnation can contribute to damaged leaf tips. Poor airflow inside the racks prevented heat and moisture removal, making uniform crop-level airflow essential for stable growing conditions.

Direct airflow between growing racks

Placing ducts close to the crops delivered air deep inside the racks, rather than relying on whole-room supply, reducing stagnant zones above the leaves.

Designed for airflow above 0.5 m/s

The target was at least 0.5 m/s at crop level. Gentle, uniform airflow passed over the plants instead of a strong one-directional draft, helping reduce temperature and humidity variation and tip-burn risks.

Reducing temperature, humidity and tip-burn risks

FlowSox displaced stagnant air above the crops, removing heat and moisture and reducing differences between racks and risks associated with insufficient airflow.

Airflow above 0.5 m/s at crop level

Airflow above 0.5 m/s directly over the vegetables enabled more precise growing-environment management than supplying air to the whole room.

More consistent temperature and humidity

Continuous removal of heat and moisture above the crops reduced differences between rack locations and stabilized the growing environment.

Improved tip-burn conditions

Consistent crop-level airflow helped address tip burn associated with stagnation, removing heat and moisture and supporting more uniform growth.
