How do LED plant lights feed your indoor plants?
Everyone will plant more or less plants in their homes, which can be played in their spare time and beautify the environment. Not everyone has the time and energy to take care of plants. Led plant growth lamp is a special kind of lamp. According to the growth law of plants, it must need sunlight. LED plant growth lamp is a kind of lamp that uses the principle of sunlight to replace sunlight to provide the environment for plant growth and development.
What we need to know is that the growth rate of plants depends entirely on the intensity of light, that is, the amount of light radiant energy absorbed by the surface of the plant, not the number of light sources. Many people ask, what is the meaning of the interior lighting of the greenhouse, how to do it, and which light source should be used?
The significance of the lighting inside the greenhouse is to extend enough light intensity in a day. It is mainly used for the seedlings of vegetables, roses and even chrysanthemums grown in late autumn and winter. Greenhouse lighting has a great influence on the growth period and the quality of seedlings. Usually, for tomatoes, the light starts after two cotyledons are grown on the plant seedlings. Continuous light for 12 days can reduce the seedling preparation period by 6-8 days. But more than 24 hours of light will cause plant growth disorder.
The most suitable light time is 8 hours a day. On cloudy days and low light intensity, artificial lighting is a must. At least 8 hours of light per day should be given to the crops at night, and the time of light per day is fixed. However, the lack of night rest can also cause plant growth disorders and reduce production.

Led plant growth lamp is a special kind of lamp, according to the law of plant growth, it must require sunlight, and led plant growth lamp is a kind of lamp that uses the principle of sunlight to replace sunlight to provide the environment for plant growth and development.
After the application test led, the wavelength of the plant light is very suitable for the growth, flowering and fruiting of plants. Generally, indoor plants and flowers will grow worse and worse with time. The main reason is the lack of light irradiation. The LED light of the spectrum required by plants can not only promote their growth, but also prolong the flowering period and improve the quality of the flowers. The application of this high-efficiency light source system to agricultural production such as greenhouses and greenhouse facilities, on the other hand, can also make Solanum fruits and vegetables in greenhouses are put on the market in advance before and after the Spring Festival in winter, so as to achieve the purpose of off-season cultivation.
1. As a supplementary lighting, it can be used to enhance the lighting at any time of the day, which can extend the effective lighting time.
2. Whether it is at dusk or at night, it can effectively extend and scientifically control the light required by plants.
3. In greenhouses and plant laboratories, it can completely replace natural light and promote the growth of plants.
4. Completely solve the situation of eating food in the seedling stage, and arrange the time according to the delivery date of the seedlings.
The significance of the interior lighting of the greenhouse
What we need to know is that the growth rate of plants depends on the intensity of light, that is, the amount of light radiant energy absorbed by the plant surface, not the number of light sources. Many people ask what is the meaning of the interior lighting of the greenhouse, how to do it, and which light source should be used?
The significance of the interior lighting of the greenhouse is to extend enough light intensity throughout the day. It is mainly used to grow vegetables, rose and even chrysanthemum seedlings in late autumn and winter. Greenhouse lighting has a huge impact on the growth period and the quality of seedlings. Usually, for tomatoes, light starts after the plant seedlings grow two cotyledons. Continuous light for 12 days can reduce the seedling preparation period by 6-8 days. But more than 24 hours of light will cause plant growth disorders. The most suitable light time is 8 hours a day. On cloudy days and low light intensity, artificial lighting is a must. At least 8 hours of light per day should be given to the crops at night, and the time of day light should be fixed. However, the lack of night rest time can also cause plant growth disorders and reduce production.
Plant light fill light
LED plant light is a special light with a specific spectrum wavelength designed to replace sunlight with light emitted by LED light-emitting elements, specifically to promote photosynthesis of plants and create a suitable light environment for plant growth and development.
LED plant lights can control the spectral wavelength very well, and can fully meet the needs of plants for light. The spectral wavelength required for photosynthesis of plants is usually in the range of 400 ~ 720nm. The blue light of 400 ~ 520nm and the red light of 610 ~ 720nm contribute the most to the photosynthesis of plants. The wavelength of the red and blue light of the LED plant light is within this range, which can provide the plant with a spectral wavelength suitable for its growth, and can promote the growth of the plant.
At the same time, LED plant lights are also energy-saving (high photoelectric conversion efficiency, power consumption is 1/4 of fluorescent lamps and 1/10 of sodium lamps), adjustable spectrum, good point light source, cold light (low heat), good It has the characteristics of moisture resistance, small size and long life (more than 30,000 hours).
Plants "walk" from outdoor to indoor
Studying the growth behavior of plants outdoors not only covers a large area, but there are also many uncertain factors that cannot fully quantify the research parameters of plant cultivation. Indoors are completely different. What kind of questions does each plant need in different growth periods, what kind of humidity, what kind of light, what kind of light quality will grow best, and under what circumstances What are the different changes? With these quantitative parameters, different plants can be planted in various growth states according to the different needs of human beings. Only LED plant lights can make plants "walk" from outdoors to indoors. At present, only LED plant lights can enable indoor research to achieve the highest efficiency.
Plant light installation height
The installation of LED plant lights must be scientific in order to effectively improve the light utilization rate of plant lights. In order to ensure the plant's supplementary light intensity, the plant's supplementary light should be placed as close as possible to the plant, and the distance should be set according to the power of the plant's light. Generally, the closer the distance between the plant lamp and the plant, the higher the light utilization rate. Use LED plant lights to fill the light. Since the LED has very little heat energy, it will not burn the plants. It can be irradiated at close distances, and the shortest distance can be 10 cm. Generally, for plant lights with power less than 8W, the irradiation distance is about 0.5 meters, and for plant lights with power greater than 8W, the irradiation distance can be between 0.7-1 meters.
Plant light fill time
Depending on the growth period and growth environment of plants, the time it takes to fill light is different. Indoors where the light is not strong but can shine into the astigmatism of the sun, the fill-in time should be no less than 5 hours; for balconies with less than 4 hours of light (only in the morning or afternoon with light for half a day), the fill-in time should be no less than 4 hours ; Shady areas and indoor areas without sunlight should be filled with light for no less than 10 hours. Generally, the time for supplementing light during the growth period of plants is longer, and the dormancy period is less. No less than 10 hours of supplementary light should be provided on cloudy, rainy and foggy days. Another thing to note is that since plants mostly photosynthesize during the day and grow at night, there is generally no need to supplement light at night.
When plant growth and development are affected by factors such as weather and seasons, insufficient light, normal photosynthesis cannot store organic matter, growth and development cannot proceed normally, and serious conditions may directly wither and die. With the emergence of LED plant lights, plants get rid of the limitation that they can only rely on the sun to grow normally. It can also increase crop yields, shorten the cycle of plant growth, and produce high-quality, high-volume, green and environmentally friendly crops.
