The United Nations predicts that the world's population will grow by 2.3 billion people by 2050, and that 68% of us will live in cities. Worryingly, 80% of the land that is suitable for growing food is already in use. This is driving the emergence of city farming, which involves growing plants indoors in multilayer stacks with no access to natural daylight at all.
With no natural daylight, the right artificial lighting is essential. The use of these pioneering LEDs offers a significant advantage over traditional horticultural lamps, producing light in very pure colours and spectral levels that increase harvests and regulate quality. Using LEDs and optimised lighting, 'recipes' have a big role to play in modern horticulture: improving yields, cutting energy consumption, allowing us to enjoy our favourite produce year-round and increasing nutritional value.
