0405pess01 Red LEDs to Grow Lettuce betterThis is pretty neat- using red LEDS to grow lettuce is 60% more efficient than fluorescent light when growing vegetables hydroponically. The red LED technology produces 7000 heads of lettuce per day all year round in a 10-floor building on just 1000 square meters of space. The lettuce matures more than three times as fast under the LEDs than outdoors. The Metaefficient site also has a lot of other interesting products that are just, better. Maybe when we’re all done with our POV projects we’ll grow plants.
