What is a plant growth light?

Plants need light for nutrient uptake. They use the energy of light for photosynthesis to obtain the necessary nutrients for growth and development.Therefore, photosynthesis is the key to the survival of plants.LED plant life lamp is a kind of special lamp with specific spectral wavelength designed to replace sunlight with the light emitted by LED light emitting elements, specially promote plant photosynthesis and create a suitable light environment for plant growth and development..

Effects of different spectra on plants

280 ~ 315nm : The effects on morphology and physiological processes are minimal
315 ~ 400nm :Chlorophyll absorption less, affect photoperiod effect, prevent stem elongation
400 ~ 520nm (Blue):The absorption ratio of chlorophyll and carotenoid was the largest and had the greatest influence on photosynthesis
520 ~ 610nm (Green):The absorption of pigment is not many

610 ~ 720nm (Red):Chlorophyll absorption rate is low, which has significant effect on photosynthesis and photoperiod effect

720 ~ 1000nm :Low absorption, stimulating cell elongation, affecting flowering and seed germination

>1000nm : : Convert to heat

Light quality:Effect of red light 610-680nm

1. Red light is the main force of photosynthesis, and it works best under certain blue light conditions.
2. In low light environment, red light has the highest photosynthetic efficiency for plants
3. Red light controls photoperiod and flowering rhythm Pr/Pfr -- affects flowering;
4. Red light mainly helps plants produce carbohydrates that make them grow taller and bigger.

Light quality:Effect of blue light 420-470nm

1. In low light environment, blue light has less effect on photosynthesis than red light.
2. Blue light plays an important role in the early stage of plant growth and helps to establish a developed root system.
3. Blue light inhibits the growth of the main stem and leaf, but increases the thickness of the main stem.
4.Chlorophyll a/b has a strong absorption peak in the blue light region, which mainly helps plants to synthesize proteins and amino acids.
5. Proper blue light makes plants grow more evenly and healthily, improving the quality of their output.

Light quality:Effect of green light 500-570nm

1. Green light has a certain effect of promoting plant photosynthesis;
2. In strong light environment (in combination with other light quality), green light plays a more important role;
3. Green light can penetrate the canopy and increase overall photosynthesis;
4. Green light can be neutralized by red and blue spectrum to reduce visual "light pollution", and the visual effect is good when light is mixed.

Light quality:Effect of UV light 360-420nm

1. Purple light is the central region of plant phototaxis and can affect plant morphogenesis;
2. Purple light inhibits the growth of main stem and leaf of plants (inhibits apophysis);
3. The purple light can stimulate the anthocyanin of plants, and promote the coloring of fruits/petals or leaves to improve the quality.

Light quality:Effect of IR light 730-750nm

1. Emerson effect(double light gain effect)
In 1957, biologist Robert Emerson discovered that the photosynthetic efficiency of green plants was much higher when red light (wavelength 660nm) and infrared light (wavelength >700nm) were irradiated together than when green plants were irradiated separately at 660nm.
2. Shade avoidance by plants
Infrared light is also the sensitive spectrum of phototaxis of plants. Under the irradiation of infrared light, plants feel that there are objects blocking the light at a high place and inhibiting their growth. They will strive to grow higher and promote the rapid growth of plants..
