How do I design a "light recipe" for a plant?
It is precisely because of the plant's "recognition" and "preference" of light that it provides theoretical guidance for artificial light cultivation plants.

About the spectrum
In the seven-color light, the photosynthesis of the plant is mainly regulated by red and blue light, which affects the yield.
This is because when plants perceive more red light through a "catch antenna," they release a hormone that prevents chlorophyll from breaking down. This allows plants to convert light energy into more chemical energy, allowing them to grow stronger. In addition, plants also need red light exposure to normal flowering and results.
The plant's blue light receptor triggers a hormonal reaction when it perceives higher levels of blue light, slowing the growth of the stems and leaves, so blue light can help plant stems grow stronger.
About light strength and light cycles
In addition to the composition of the spectrum, plant growth requires appropriate light intensity and light cycle.
Within a certain range of light intensity, the photosynthesis rate of plants accelerates with the increase of light intensity, but does not simply increase the intensity of light. For each plant or every stage of development, excessive light strength on the one hand leads to light suppression phenomenon, affecting yield and quality, on the other hand, also waste a lot of electricity, increase investment costs.

Design "light recipes" for plants
After fully understanding the demand for light formulations in different plants and different growth stages of the same plant, the researchers designed the "light recipe" and used LED "core light" technology to balance the relationship between yield, quality and energy consumption, and designed AN LED plant light that can meet the energy needs of plant photosynthesis and suitable for its growth and development, while saving energy and cost in production, to achieve artificial light instead of sunlight to help plants grow healthily.
LED plant lamps with suitable light formulations not only ensure the efficient use of plant photosynthesis, but also special light formulations can regulate plant behavior like condiments, making vegetables more delicious and nutritious, flowers more vivid, fruit sweeter and more nutritious.
Controlled "Sun"

Young leafy vegetables grown under LED plant lamps
LED plant lamps are powerful because they are energy efficient and have a long service life, while the heat output is low and can be closer to plants, making them ideal for indoor farming. Compared with the sun, LED plant lamp's greatest advantage is its controllability.
We know that the sun is a source of energy for all things to grow, but it is not foolproof.
The rotation of the earth causes the sun's position to change and the rainy weather to "disappear", which means that plants cannot always sunbathe. In addition, sunlight is shared by everything and does not favour any kind of plant, only plants to adapt to it.
The emergence of artificial light, especially the birth of LED plant lights, everything is different.
Unlike the instability of the sun, LED plant lamps do not change intensity with day or night, summer or winter, rainy or sunny days, providing stable and consistent light for plants.

LED plant lamps allow growers to "control" light
In addition, as mentioned above, we can precisely design and tailor the light formulations of our plants. For example, to different crops to shine different light, tomatoes like purple light on more purple light, blueberries prefer red light on more red light Seedlings grow more robust; this period of red light easy to cause plants to grow thin, then control the amount of red light;
LED plant lamps give farmers access to the "sunshine" they need anytime, anywhere, providing them with something they can't have in the sun, which is "control."
