Color variations of the LED grow lights are directly related to their intended purpose – numerous studies have demonstrated that certain colors influence plant growth by affecting root and flower formation (blue and red light spectra), which means that the majority of plant species will complete a normal growth cycle if exposed to both blue and red grow lights. Adding more hues to the spectrum, such as green, far-red, and deep-blue, assists in this process by providing plants with more information about their surroundings, resulting in higher-quality plants overall (quicker growth, more secondary metabolite accumulation etc). Full spectrum is a spectrum that comprises all colors and closely mimics sunshine. If the light contains a large percentage of green, it will seem white to the human eye. While this is not a necessary component for plant development, it does make working around the lights simpler and allows for visual examination of the plants.
