Why Full Spectrum?

Spectrum King LED Grow Lights are designed to mimic natural outdoor sunlight. Why change what Mother Nature has already perfected over millions of years? Sunlight includes many spectrums, both visible and ones we cannot see; even traditional HPS lights put out a high band of nano-meter wavelengths (color spectrums) which is why it has been successful in the agriculture application today. LED grow lights that provide only 2, 3, 4 even 8 colors will never come close to reproducing the effects of sunlight.

Spectrum King LED Grow lights consistently produce spectrums from 380-779nm. This means that not only virtually every visible color is present in the light, but also ones you can’t see. The Spectrum King Series 300 and Series 400 LED Grow Lights truly mimic sunlight and traditional HPS lamps with matching intensities of over 100,000Lux.

We all know that blue and red are the wavelengths that dominate the “active photosynthesis” portion of the spectrum, so you might think that providing these colors alone might circumvent the rules of nature. But there is a problem: Productive plants need to photo-respirate. When plants become heated (by intense yellow light) the stomata on the leaf surfaces open up and allow photo-respiration to occur. When photo-respiration takes place the plants go into “work out” mode and want to consume nutrients just like humans want to drink water. Traditional LED arrays only carry the spectrums that activate after the photo-respiration period takes place. This is the reason traditional LED lights sometimes finish cycles with immature plants that produce low yields. By supplying plants with only limited “beneficial” spectrums (pink light) from traditional LED arrays, you are essentially putting them into a permanent chill mode. Although this may produce healthy plants, they will not yield as much as plants under Spectrum King LED Grow Lights.
