Philips Lighting promotes city farming

“City farm vegetables are fresh, nutritious and safe, grown in a responsible way”

Why are LEDs extremely suitable for city farms:

With LED lighting it is possible to provide exactly the wavelengths which are useful for growth and development of the crop. Contrary to the sun, traditional assimilation lighting and TL lighting, LED only omits one color of light. No energy is wasted with light spectra that are not used or less used by the plant. This means that LEDs provide exactly the colors which the plant needs for photosynthesis. Plants mainly need blue and red light for photosynthesis and far-red, a color not even visible to the human eye but visible to the plant.

A city farm is a closed room where plants are grown in several layers to make best use of space. As there is no influence from outside, in the farm room the conditions can be kept constant and hygienic, so people can enjoy safe vegetables all year round, independent of seasons and weather. The city farm is designed to minimize the use of valuable natural resources: it requires only 20% of water, space and energy compared to traditional ways of growing.
