The Sun Shelf lights utilise both the red, blue, and full spectrum light frequencies, to create an optimised growing experience for plants and a more desirable light colour for people.
You can change both the light intensity setting and the timer setting of the pair of grow lights. If using the grow shelf, one can easily adjust the height of the grow shelf unit. The closer to the light, the plant is the more light your plant will receive.
