How to Choose LED Grow Lights

What type of LED is best for growing cannabis plants?

The original LED grow lights are often known as “blurples” because they focused on providing plants exactly what we thought they needed, since photosynthesis peaks in the red and blue wavelengths of light. Because they offered such a specific set of wavelengths, these types of lights are also called targeted or narrowband lights. 

Since then, we have come to understand that plants benefit from a broader spectrum of color. While high-quality and properly balanced narrowband light can still get the job done, a full- or broad-spectrum of light will produce healthier plants overall.
