These Kind LED grow lights use only about half the electricity as HPS lights, and produce much more yield per watt. Many studies have even show an increase in oil production and quality, closer inter-nodal spacing, and denser fruits and flowers. Also, because these Kind LED grow lights produce less heat, they do not need to be air-cooled like HPS lights, therefore eliminating the need for additional fans, which also makes them run quieter. Kind LED lights run cool, so cool in fact that no additional temperature control equipment is needed besides the internal circulation fans. Lower light temperatures lead to a much more easily maintained ideal grow environment in which your plants would thrive. Because the individual diodes of a Kind LED light are set to a specific color and in a specific proportion, we are able to emit the exact spectrum that a developing plant would need to thrive, with little to no waste. The 12 band complete spectrum is designed to perfectly match the growth needs of your plants. Kind LED Growers will be able to simplify their grow rooms, save on electrical consumption, keep their rooms cooler, and perhaps most importantly, experience a marked increase in the quality of their fruits, flowers, and vegetables.
