What is plant grow lights?

Plants growth rely on sunlight to absorb nutrition, so they need to obtain nutrition of growth and development by utilizing sunlight energy for photosynthesis. Therefore, photosynthesis is the key to plant survival. Led grow lights are special lamps with specific spectrum wavelength to replace sunlight with light emitted by Led lamp (bead), they are specially designed to promote photosynthesis and create suitable environment for plants growth and development.

Photosynthesis

Wave Bands influence on plants

315 ~ 400nm :Grow light wave band range from 315 to 400nm absorbing Chlorophyll less which will affect light Periodic effect and prevent stem growth.

400 ~ 520nm (Blue):Its largest absorption ratio of chlorophyll and carotenoid which affect photosynthesis greatly.

520 ~ 610nm (Green):Green wave band plant light with low absorption ratio of chlorophyll.

610 ~ 720nm (Red):Its low absorption ratio of chlorophyll with obvious influence on photosynthesis and light periodic effect.

720 ~ 1000nm  :This wave band with low absorption ratio to stimulate cell extension and affect plants bloom and budding.

Wave Bands function to plants

Red wave band light 610-680nm function to plants:

1. Red wave band light is the main element to photosynthesis and it combines with blue light under certain conditions can bring about best photosynthesis effect.

2.Red wave band light affects photosynthesis efficiency mostly when light is dim.

3. Red wave band light control light periodic effect and blossom rhythm to affect bloom date.

4.Red wave band light is mainly helpful for plants carbohydrates making and make plants become taller and leaves growth.

Blue wave band light 420-470nm function to plants

1.Blue wave band light with weak affect to photosynthesis than Red wave band light under dim light circumstances.

2.Blue wave band light affect plants growth much at first stage and help plants to build strong roots system.

3.Blue wave band light inhibit plants stem and leaves growth, but can make plants become strong in width.

4.Chlorophyll a/b with high absorption ratio during blue wave band light 420-470nm,which is mainly helpful for Plant proteins and amino acids synthesis.

5.Appropriate blue wave band light can make plants grow evenly and healthfully to promote plants output quality.

Purple wave band light 360-420nm function to plants

1. Purple wave band light is the central wave band area of plant phototaxis, which can affect the morphology of plants.

2.Purple wave band light inhibit plant stem and leaf growth.

3.Purple wave band light can stimulate the anthocyanins of plants and promote the coloring of plant fruits / petals or leaves for quality improvement.

Infrared wave band light 730-750nm function to plants

Emersoneffect:Biologist Robert Emerson found that photosynthesis efficiency of green plants is more higher than wave band light 660nm when they are shining by both Red wave band light(660nm) and infrared wave band light than only be shining with 660nm.
