What is spectrum? How important are they to plants growth？
Although natural light may appear white to us, it is actually composed of many different colors. When passing light through a prism, or when we see a rainbow, we can see the "true face" of the sun's rays. When the light is refracted to its various parts, we can see all the colors that make up the light.
 
Over the years, we have learned that plants actually make "decisions" on how to grow based on the spectrum they receive. Different spectra can change the way in which plants germinates, grows, and even blooms. Although there are not many options to change the spectrum of sunlight when growing outdoors, since many users now use plant growth lights, we can almost completely control the spectrum when growing plants indoors!

Why can  plants respond to the spectrum?

When grown outdoors in the sun, the received spectrum actually provides the plants plant with a lot of information about what is happening in the world around it. In spring and summer, more blue spectrum reaches the surface.
In summer, the plant responds to this bright direct light (with a lot of blue light components), suggesting that it has many large leaves and short stems that grow non-nutritively. The plant tries to spread as much as it can and increase the quality of its leaves.

Blue light-Plant growth lamps with a higher proportion of blue light are often used in the plant growth stage because they tend to make plants plants short and strong, and have large healthy leaves.
As autumn approached, the sun began to drop in the sky. As a result, more light reaching the plant falls within the red spectrum. More light in the red part of the spectrum indicates that the plant is about to end summer and it is time to adapt before winter. When a plants plant is exposed to a higher proportion of red light, it will respond by growing longer stems and leaving more space between the leaves, and grow as high as possible to the best condition to start Sprout and pollinate by wind!

Yellow/red light-grow lights with a lot of red are often used during the flowering period to encourage plants to grow taller (stretch) and help promote budding. Under red light, plants may enter the flowering period faster than under blue light.

By tracking the ratio of colors in the spectrum, plants plants can "understand" what is happening around them, thereby helping the plant grow in the best way!

If you want to make plants dwarf and grow more leafy, it is recommended to use plant growth lights with more blue spectrum components. Switch the plant to the flowering period, you can switch the light to the part of the plants that likes more red and orange during the flowering period.
 

How much influence does spectrum have on plant growth?

The plants plant needs bright light, at least some red and blue, for it to grow normally. Although it is certainly not essential for healthy plant growth, it is considered a good form of choosing light of the appropriate spectrum to encourage your desire to grow during the nutrient and flowering period of the plants plant.
However, remember that different strains will be affected differently by the spectrum. Some plants are barely affected, while others may react more strongly. It is important to remember that the changes caused by the spectrum are relatively small (for example, stems tend to grow longer), and many other factors will drive some of the same changes.
 
On the other hand, if a plant is provided with a lot of yellow light, it tends to last very short because it gets so much light that it has enough blue and does not need to be high. Since almost all grow lights emit a spectrum suitable for healthy plants growth, in many respects, the amount of light has a much greater impact on plants than the spectrum.
 
The best way to increase yield is to make your plants more "simple"In other words, giving plants more light than simply changing the spectrum can give you a greater yield return. Therefore, if it is possible for your plants to get more light (the highest), even if you add light in the "wrong" spectrum, this will increase your yield. Even bright white fluorescent lamps immersed in the green spectrum can promote plant growth, if you don't care about energy consumption.

What is the "best" spectrum for growing plants?

This is a big problem because each spectrum has its own unique influence, and some spectrums are more useful for plants growth than others. Through research and discovery, our plant growth engineers have found that they are relatively suitable for plants cultivation. The spectrum.
 
Our plants grow lights use this kind of spectrum. After our customers’ evaluations, our planting lights can increase the yield while ensuring and improving the quality of plants. It is an excellent full-spectrum LED plants planting light. .
