Reliable & Powerful

Experienced cannabis master growers know plants perceive and adapt to their environmental surroundings throughout their life cycle. GrowRay’s full-spectrum LED lights have been proven to increase indoor cannabis cultivation efficiency and yields. Research in the cannabis industry points to more data reinforcing the benefits that full-spectrum commercial LED lighting provides in commercial grow operations.

The integration of a GrowRay commercial LED lighting system enables you to use far less electricity than a traditional HPS light and has data-backed evidence supporting full-spectrum lighting as the best option when it comes to lighting that mimics the intensity and spectrum of natural light from the sun.
