What’s the Best Light Spectrum for Flowering Plants


Ways Yi   2020-11-9


Plants can't grow without light. In general, flowering plants grow based on full spectrum of visible light, but not all the wavelengths is the same important. The right spectrum, light intensity and light duration work together to stimulate flowering, growth and reproduction.


The visible spectrum consists of red, orange, yellow, green, blue, indigo, and purple light.

The yellow and green wavelengths have little effect on plant growth, while the colors at both ends of the spectrum have the greatest effect on plant growth and flowering. As the plant energy is derived from photosynthesis, plants need absorption wavelengths in the 400-700 nanometers (nm) range. Different plants require different wavelengths, so they absorb different amounts of wavelength. A lot of red and blue light is absorbed, while green and yellow light is reflected, so the leaves look green. Because of this, the manufacturer like LONG SUN optoelectronics that product LED grow lights focus on the blue and red parts of the spectrum.


Longsun® - a 12 years experienced grow light manufacturer in China, focusing on lighting OEM & ODM service. They just launched out a new grow light with balanced full spectrum including 3000K, 5000K, deep red 660nm, IR 760nm which optimized and complete plant development for all growth stages from seed to flower.


So, how does these different light work on plants?

Warm White Light (3000K)

Boosts plants blooms, makes flower bigger and vivid.


Blue Light (450nm, 5000K)

Promotes plants germination. Increase the growth rate of plants.


Red Light (660nm)

Yields more leavers and crops when combined with blue light


IR Light (760nm)

Speeds up the Phytochrome conversion, allows the plant to produce a greater yield.
