Korean farmers are using LED lighting to help their crops cope with the lack of sunlight. LED lights give the crop the extra light and help improve the results. Solid colored, usually red and blue, LEDs are the best solution especially for indoor gardening. Blue lights are best for the vegetative growth period, while red lights are better for the flowering phase.
LED lights create only one tenth of the energy costs barely create heat, and in most cases work better than the sun.
Famers that were interviewed by Korean newspaper Arirang told their LED lit harvests were 44% larger than the average of 37 Kg of bell pepper per 3.3 m2, and stems where 23% shorter. This means an easier work for the farmers.
LED grow lights present a nice alternative to regular indoor growlights.
