Comment: Technology will be crucial to the success of vertical farms

Envirotec Magazine

Temperature and humidity at the JFC facilities are controlled by a separate HVAC system, but Christoph says: “The HVAC at JFC1 came with its own sensors, so we have replaced them with Vaisala’s. At JFC2 we will use the Vaisala sensors to check and validate the measurements being made by the HVAC system, and intervene if necessary.”
