Using only the light wavelengths plants need, specific LED lighting saves energy for greenhouse food crops

HollandTradeNews | October 25, 2010 | Since recently, the Netherlands have the world’s highest penetration of LED lights. LED lights use up to 90% less energy than normal bulbs, which makes them highly attractive for energy-intensive and cost-competitive industries such as greenhouse growers. Interestingly, the light that is needed for growing green plants is ideally red and blue. LED technology allows you to produce only those colours, again saving energy because you don’t have to produce green or white light. We visited a grower of cresses (micro vegetables), who has recently installed a multilayered LED systems, which saves him money and space.
