We all know plants need light to grow and be healthy. Indoor plants often suffer from too little sun and can benefit from artificial light. Most lighting options today feature LEDs due to their long life and low energy use.
What is LED Grow Light?
LED grow lights are energy-efficient lights used by indoor and greenhouse farmers and Cannabis growers too. Used as either a sole light source (indoor) or supplementary (greenhouses), LEDs help plants grow using full-spectrum lighting at a lower cost than traditional HPS lamps (1).
Many growers take advantage of LED lights to help scale plant production due to their full light spectrum capabilities, low heat waste and maintenance, and extended lifespan. And given a plant’s physiology and morphology are strongly affected by specific spectrums, LED grow lights can efficiently promote growth in crops (2) at specific times in the growth cycle. With the ability to closely monitor quality, energy output can be easily evaluated for scaling crop production.
What is Grow Light Spectrum?
Grow light spectrum refers to the electromagnetic wavelengths of light produced by a light source to promote plant growth. For photosynthesis, plants use light in the PAR (photosynthetic active radiation) region of wavelengths (400nm-700nm) measured in nanometers (nm).
Nanometers are a universal unit of measurement but also used to measure spectrum of light – humans can only detect visible light spectrum wavelengths (380-740nm). Plants, on the other hand, detect wavelengths including our visible light and beyond, to include UV and Far Red spectrums.
It’s important to note light spectrums affect plant growth differently depending on things like environmental conditions, crop species, etc. Typically, chlorophyll, the molecule in plants responsible for converting light energy into chemical energy, absorbs most light in blue and red light spectrums for photosynthesis. Both red and blue light are found in the peaks of the PAR range.
What is a Full-Spectrum LED Grow Light?
A full-spectrum LED grow light is simply a marketing term that implies that your grow light closely resembles light from the sun. This marketing term comes from the concept of “full-spectrum light,” which in recent years has been used to refer to electromagnetic radiation from the UV to infrared wavebands.
The History of the Full-Spectrum LED Grow Light
The full-spectrum LED grow light is the newest evolution of an already confusing term. Originally, full-spectrum light described the only real full-spectrum light source, the sun.
Over time, the term began to take on other characteristics of sunlight. The commercial lighting industry began using the name “full-spectrum” to sell lights that produced a Color Rendering Index (CRI) over 90. Humans perceive colors more accurately under light sources with a CRI over 90, much like how we see colors in our natural world under daylight. This was a beneficial feature for human environments such as offices, outdoor spaces, and others.
Grow lights, although artificial, try to mimic the sun as naturally as possible. In doing this, you typically have a varied light spectrum available for your grow lights. Besides the color spectrum, it’s also possible to have control over the color temperature and the luminous efficacy with grow lights.
There are two good-quality full spectrum led grow lights for your indoor plants.

Conclusion
There’s a great deal of information and science to take on board as we understand the way plants interact with different light spectrums. Optimizing yield production and consistent quality of plants we’ve learned are attributed to light spectrums used together – much like natural sunlight.
We’re constantly developing our knowledge and research of how light spectrums on specific crops and strains work best – and at which time during a plant’s light cycle. Our LED grow lighting systems are designed and developed using detailed scientific research to give growers the control of using the ideal light spectrum for optimizing the yield, quality, and variability of their plants.
