Food security is major challenge globally due to growing populations and high levels of urbanization. Quality, quantity and location of food production are becoming increasingly important. Certhon has developed a multi-layer growing system and production growth chambers in which crop cultivation takes place in a fully controlled climate, without natural sunlight. The system integrates i.e. cooling and heating installations, irrigation, LED lighting and the possibility to cultivate on multiple levels, ventilation systems, internal transportation, and a turnkey ICT system. As climate conditions can be fitted exactly for specific crops, these growing systems improve product quality and increase productivity.
