There are technologies based on the use of both natural and artificial light, and ones without access to sunlight, using only artificial light sources for the plant growth. The technologies used here include LED lamps, compact fluorescent lamps, metal halide lamps and fluorescent bulbs. Studies are conducted on the effects that different colors of light from LED lamps have on the quality and growth rate of plants. Their results allow us to conclude that certain crop growing systems utilizing lighting from LED lamps in urban vertical farms provide yields several times greater than in traditional farm with a comparable cultivation area. One phenomenon accompanying the use of artificial light is the possible occurrence of the light pollution effect.
