Today, more than half of the world’s population lives in cities. In 2050, two-thirds of all people will live in conurbations. Traditional agriculture will not be able to cope with supplying the mega-cities with healthy food.
One possible solution is urban farming – fruits and vegetables grown in the city in “farmscrapers”, i.e. high-rise greenhouses. Special LED lighting systems with a special color spectrum provide ideal growing conditions regardless of the weather outside.
Advances in LED technology were the decisive factor for the development of such “indoor farms”. The energy-efficient light-emitting diodes hardly lose any heat and can replace the sunlight which is indispensable for plant growth. For photosynthesis and therefore biomass production, plants only use certain components of the natural light spectrum – mainly red and blue. Compared with conventional lighting solutions for plant cultivation, LEDs increase energy efficiency considerably and can therefore promote the breakthrough of vegetable and fruit cultivation in large cities around the globe.
