Grow LED

Horticultural LED systems and the spectral science they have made possible have already revealed some amazing effects, including: using light alone to create bigger yields per plant; producing more marketable crops overall; and changing the wavelength of light to change the flavor of foods. For these reasons and others, including the ones detailed below, LEDs are on their way to replacing legacy lighting systems in many new and newly renovated growing operations.

For dual chips Red & Blue COB grow LED, 30W / 50W /100W are available, providing our customers more solutions based on different designs and applications, for customized services, please kindly contact our sales for support.

Blue Light

The most important blue wavelengths are from 439 to 469 nm. This part of the spectrum is also known as cool light. These wavelengths encourage vegetative growth through strong root growth and intense photosynthesis. Blue light is often used alone during the early phases of plant growth, such as starting seedlings, when flowering is not desired.

Red Light

The longer wavelengths of light are red in color. The most important wavelengths in the red spectrum are from 640 to 680 nm. These wavelengths encourage stem growth, flowering and fruit production, and chlorophyll production. The red wavelengths are known as warm light, and they are naturally more prevalent in sunlight during the shorter days of fall and winter.

Far Red Light

Although the 730nm wavelength is outside the photosynthetically active range, it has the strongest action on the far-red absorbing form of phytochrome, converting it back to the red-absorbing form. Plants requiring relatively low values of the phytochrome photoequilibrium to drive the flower cycle. The 730nm wavelength can be used at the end of each light cycle to promote flowering in short-day plants such as Cannabis.
