How Green Light Affects Plant Growth
In LED horticultural lighting, red and blue wavelengths
were thought to be the only part of the spectrum
that drove photosynthesis because chlorophylls are
receptive to those colors. New research now reveals
that previously dismissed green light can also drive
plant growth. Fluence Bioengineering’s chief innovation
scientist Dung Duong explains the new data.

T
he current state of the LED
horticultural lighting industry would
lead some to believe the world only
exists in shades of red and blue. Thanks
to narrow readings of research done by
Dr. K.J. McRee and Dr. Katsumi Inada,
a general consensus in the industry is
visible ranges of red and blue light are
the only wavelengths of light needed
to induce photosynthesis.
