Quick introduction: Indoor Farming


© Fraunhofer IKTS

Despite the use of modern and energy-efficient LED technology, the exposure of phototrophic organisms such as plants and algae generates a considerable thermal load, which in turn has to be dissipated via air-conditioning technology at great energy expense. The IKTS solution is the use of pulse-width modulated lighting, in which the photon uptake processes in phototrophic organisms and the photon emission of the lighting technology are synchronized. This means that less energy is required to provide the light. As a result, the requirements for climate control in the culture room are reduced accordingly. The IKTS has test stands in which a wide range of light qualities and quantities can be generated. Both substrate-bound and hydroponic systems are available for the cultivation of phototrophic organisms.
