We report on the application of flashing amber (596 nm) light-emitting diodes (LEDs), supplemental to high pressure sodium lamps, for the cultivation of green sprouts, such as wheatgrass, barley grass, and leafy radish. The flashing light was found to significantly affect metabolism, thus conditioning the nutritional quality of the sprouts. In particular, it causes stressful conditions for the plants and within a short growth period can promote the synthesis of antioxidative compounds, such as
