1. Application of LED plant grow lights
The LED plant lights used in the fields of plant tissue culture, seedling cultivation, growth, and supplementary light are rich in wavelength types, which are just in line with the spectral range of plant photosynthesis and light morphology; the spectral wave width is narrow at half width, and can be combined as needed to obtain pure monochromatic light and compound spectral, concentrated light of specific wavelength to irradiate crops in a balanced manner, not only can adjust the flowering and fruiting of crops, but also control the height of the plant and the nutrient content of the plant; the system generates less heat and occupies a small space, which can be used in a multi-layer cultivation three-dimensional combination system to achieve low heat load and miniaturization of production space. In addition, the extreme durability of LED plant lights also reduces operating costs.

2. When LED plant grow lights turn yellow:
The yellowing of the outer sealant of the LED plant grow lights is mainly due to the mismatch between the epoxy resin and the curing agent. But it cannot be ruled out that the baking time of the external sealant is too long.

Solution: The LED grow light manufacturer can purchase a complete set of external sealants and curing agents, add new production controls, strictly follow the operating instructions, and prevent the baking time from being too long or insufficient.

3. Common problems of using LED plant grow lights
(1) Generally, three 1W aluminum grow light panels are driven by about 12V, rarely used directly for 220V. If a constant current source may lack a 12V drive power supply, in the absence of sunlight, the plant light can act as sunlight, so that the plant can grow normally or better. The plant grow light can make roots strong, enhance growth, regulate the flowering period and flower color, promote fruit maturity, coloring, and improve the taste and quality of the fruit!

(2) The high-power 1W driving current of the LED plant grow light is about 350 mA, and the working voltage is between 3.2 ≤ 3.6V. Please be careful when using it. If the current is too high, the lamp will burn.

(3) The filament of the LED plant grow light is shortened, telling you very clearly that your light has been burned by a large current, which is commensurate with the broken circuit.

(4) There are two filaments up and down, called gold filaments, made of pure gold, and used for conductive purposes. Two are positive poles and two are negative poles. A really good led plant grow light will have a fifth filament, which is welded to the Zener tube to perform maintenance.

https://www.enlitehorti.com/

Among the parameters of led plant lights we often see, there is a parameter called luminous flux. But what is the effect of luminous flux on plants?

1. The definition of the luminous flux of LED plant lights
Luminous flux is of great significance to human visual perception. On the one hand, according to the difference of luminous flux, the light response felt by the naked eye is different; on the other hand, according to the difference of human vision, the naked eye has different visual perception of the same luminous flux in the same wavelength band.

Luminous flux refers to the radiant power that the human eye can feel. It is the product of the radiant energy of a certain band and the relative viewing rate of the band per unit time, and the unit is lumens (lm). Because human eyes have different relative viewing rates for different wavelengths, even if the radiant power of different wavelengths is the same, the luminous flux is not the same. Conversely speaking, even if the luminous flux is the same, if it is light of different wavelengths, the radiation power is also different.

In other words, red light with a wavelength of 680 can reach 1000 (lm) under certain condition, and green light with a wavelength of 520 can also reach 1000 (lm) under another condition.

2. The luminous flux of LED plant lights affects plant growth
For plants, the most important thing about LED plant lights is to emit the red and blue light that plants need, or full spectrum plant lamps that simulate sunlight, which are used to assist in planting high-quality plants. The most important factors that affect the lighting effect of LED plant lights include light quality, light intensity, and light time. Therefore, as for the same red light and green light with a luminous flux of 1000 (lm), one plant absorbs a lot, while the other plant almost does not absorb it, so, the luminous flux cannot be completely used as a factor that may affect the light supplement effect of an LED plant light.

However, if it is the same red light required by plants of the same wavelength, the greater the luminous flux is, it indirectly indicates that the red lamp beads of the LED plant light emit more light, the plants can get more sufficient light and grow better.

ABOUT FULL SPECTRUM LED GROW LIGHTS(2022年02月16日)

enlitehorti — 2022-02-16T15:44:13+0900

https://www.enlitehorti.com/

Some LED grow lights are nominal full spectrum, which may be to express their rich spectral components. Here is a key concept, that is, how to define the "full" in full spectrum, who defines it, and how wide the wavelength range can be called "full"?

1. LED grow lights cannot be nominal with full spectrum
Although the spectrum of sunlight is the most complete, PAR value is only described in the range of 400nm-700nm when studying the photosynthesis of plants under sunlight. Many nominal full spectrum LED grow lights for sale have some UV and IR bands, but they still use PPFD to express parameters. Because PPFD does not describe the UV and IR radiation, the parameter description of full spectrum grow lights shows low-level errors.

The wavelength range of LED grow lights is only the definition domain of the spectral absorption efficiency function, not the value domain of the absorption efficiency function. The spectral absorption efficiency is the index to measure the effect of photosynthesis. The spectrum of wide band or multi band is called full spectrum, which can not represent the effectiveness and compatibility of LED grow lights. It is not rigorous to use full spectrum to describe plant lamp, which often misleads the application of growers.

2. The complexity of LED grow lights spectrum research
For LED light source, with the same PPFD value, the spectrum shape can be different; For the same PPFD, the PPF value of the light source is different for the secondary optical design; With the same PPF value, the efficiency of lamps is different, and the PPFD value is also different; If PPFD is the same, but the spectral shape is not correct, the planting efficiency is also different.

Even if the above conditions are the same, the plant provenance is different, the growth environment and substrate are different, the planting effect is also different.

In addition, the planting effect of LED grow lights are also affected by environmental factors such as carbon dioxide concentration, ventilation and temperature control. Under the condition that the planting efficiency and quality meet the requirements of planting technology, LED grow lights need manufacturing technology to ensure that the energy consumption index is minimized, which is very important. The complexity of spectral research shows the diversity of current plant lamps. As there is no evaluation standard at present, the grow lights on the market are in full bloom.

As the leader of LED grow lights, ENLITE ENERGY INC has a professional R&D and manufacturing teams with over 20 years experience, we will constantly innovate and provide new solutions.

FIVE INNOVATIVE TECHNOLOGIES AND THEIR APPLICATIONS REPRESENT NEW ADVANCES IN VERTICAL AGRICULTURE SOLUTIONS(2022年02月16日)

enlitehorti — 2022-02-16T15:36:05+0900

https://www.enlitehorti.com/products/vertical-grow-racks/

1. Vertical farming solutions: Aeroponics
Aeroponics is a new type of cultivation method, invented by NASA in the 1990s to find effective space plant cultivation techniques. Later this technique was called "Aeroponics", which means "plants that grow in an air/fog environment with no soil and little water". This kind of vertical farming solution atomizes the nutrient solution into small mist droplets through a spray device, and sprays them directly onto the plant root system to provide the water and nutrients needed for plant growth.

In the vertical farming solutions, aeroponics is the most water-saving technology, which can reduce water consumption by 90% compared with hydroponics. At the same time, aeroponics can make plants more efficient in absorbing nutrients, and plant growth is healthier with more nutrients.

2. Vertical farming solutions: Hydroponics
Hydroponics is a new method of plant cultivation, widely used in vertical agricultural systems. This method replaces the soil with nutrient solution to eliminate bacteria and harmful substances in the soil, thereby realizing true green food production. Since the roots of the plants are immersed in the nutrient solution, the sensor can easily realize the monitoring of plant growth and nutrient components in the nutrient solution, which improves the optimal environment for plant growth.

3. Vertical farming solutions: Aquaponics
The aquaponics system is very similar to the hydroponic system, but more optimized. This method aims to integrate fish and plants in the same ecosystem. Fishes grow in indoor ponds and produce nutrient-rich wastes, which can serve as a source of nutrients for plants in vertical agricultural systems. The quality LED grow lights provide sunlight for plants. On the other hand, these plants can purify and filter wastewater for fish ponds to use. Aquaponics system simplifies production and economic issues and can maximize production efficiency. Compared with most vertical farming solutions, the current application scale of aquaponics is relatively small.

4. Vertical farming solutions: Aerofarms
By using the latest technologies such as LED plant lighting, aeroponics and climate control, it is possible to grow vegetables in an environment without sunlight, soil and pesticides. Through sensors, intelligent digital management of the entire process of crop growth can be realized, which can shorten the crop harvest period, improve food quality, and reduce the impact on the environment, making crop growth and harvest more controllable and efficient.

5. Vertical farming solutions: Lokal
Lokal, a self-sufficient small-scale household vegetable system using hydroponic farming system. By replacing the soil with nutrient solution and replacing sunlight with LED plant grow lights, people can plant and harvest crops indoors where there is no sunlight or soil. This innovation can really help people grow fresh food in their homes. The system can make plants grow three times faster than traditional planting methods and reduce water consumption by 90%. Through the sensor, the user can grasp the growth status of the crop at any time on the mobile phone.

If you want to grow plants, but you live in a place with insufficient natural light, you can choose to use LED grow lights. In some areas where there may be a long winter, plants have difficulty growing due to their inability to photosynthesize. The next best option is to use LED plant lights, so if you plan to buy some, here are some tips:

1. The plants grown
Before buying indoor plant lamps, you must know what you want to use them for. Since their main purpose is to provide the light that plants can use for photosynthesis, you need to know the type of plant that will grow. You will not use it to provide bright lights in your home or anywhere else.

When you already know which plant to grow, do some research. Find out under what conditions they will grow so that you can provide what they need. Great value LED plant light may have different functions that affect the life of plants, and different plants respond differently to various conditions.

2. The planting area
If you plan to grow plants at home, you may not need a lot of led grow lights. However, if it is a large greenhouse, several units are required. You need to know the surface area so that you can calculate the amount of light that should be provided. If the surface area is large, consider using multiple units so that each plant can receive enough light. Those directly under the light will not get photosynthesis problems because they will get enough light. However, people who are far from single light may find it difficult to grow up healthily.

Organic farming is a kind of agricultural production system that does not use chemically synthesized fertilizers, pesticides, and growth regulators, nor does it use genetic engineering and ion radiation technology. Instead, it follows the laws of nature and adopts agricultural, physical and biological methods to fertilize the soil, prevent and control plant diseases and insect pests in order to obtain safe biological and products.

In fact, fertilizers are not completely prohibited organic planting, but organic fertilizers can be used: farmhouse manure, mineral fertilizers, biological bacteria fertilizers, etc. processed by high-temperature fermentation and harmless treatment. Due to the limitation of this kind of fertilization, the growth cycle of plants is bound to be affected, and the current large demand in the market appears to be in short supply. Therefore, shortening the production cycle is one of the methods.

1. What are LED plant grow lights?
LED plant grow lights help shorten the growth cycle of plants, because the LED plant grow light source of this kind of light is mainly composed of red and blue light sources, using the most sensitive light band of plants, red light wavelengths use 620-630nm and 640-660nm, blue wavelengths use 450-460nm and 460-470nm.

2. Advantages of plant grow lights
These light sources are to make plants conduct the best photosynthesis, and the plants get the best growth state. Experiments and practical applications have shown that in addition to supplementing the light during the lack of light with LED plant grow lights, they also promote the differentiation of side branches and buds during the growth process of plants, accelerate the growth of roots, stems and leaves, accelerate the synthesis of plant carbohydrates and vitamins, and shorten the growth cycle.
With the rapid increase in global organic food demand, vigorously developing organic farming is an opportunity for more and more producers.

The aging test refers to a test process that simulates the various factors that affect the use of the product involved in the actual process and conducts the test process to strengthen the corresponding conditions. The most common is the aging test for plastics, the main methods are light aging, damp heat aging and hot air aging.

LED plant grow lights are electronic and electrical products, and their aging test is different from the aging of plastic materials. The most important thing in the use of LED plant grow lights is to allow them to be used efficiently and normally, and the main factors that affect their normal use are dead light rate, heat dissipation, high efficiency and stability of luminescence, etc. The main test methods are all done by increasing the voltage and current.

1. LED plant grow light dead light rate test, generally speaking, after the LED plant grow light is produced into a finished product, there is no problem in the studio under the rated voltage and current, but a short-term high voltage will inevitably occur during use. Or it is a sudden power failure. To ensure that the lamp can still work normally after this common situation occurs, you need to do a test before the LED plant grow light leaves the factory to detect whether the power supply configuration is qualified, the welding position is firm, and the assembled wire can withstand ability to reach a certain standard.

2. The heat dissipation test of LED plant grow light; the heat dissipation performance of the LED plant grow light is directly related to its service life and the luminous efficiency of the lamp beads. The aging test method is to make LED plant grow light at its maximum temperature within a certain period of time, and its internal structure will not be destroyed, and within a certain period of time, the temperature of each part of the LED plant grow light will not increase with the prolonged high intensity working time.

3. LED plant grow light is efficient and stable. The main influencing factor is the rectification and voltage division capability of the internal power supply. As long as the quality of the power supply is excellent, the LED plant grow light generally will ensure high efficiency and normal light emission within its rated service life. And the general power supply will be equipped with an over-voltage automatic power-off device, which will not have a serious impact on the lamp beads, but it does not rule out the possibility of LED plant grow light chip leaks during the packaging process. Therefore, a flashing test must be carried out to ensure stable, normal and efficient operation.

Generally speaking, the aging test is to test the endurance of various situations that may be encountered in its actual application, and the difference just lays in the test methods and the test process.

EFFECT OF LED PLANT GROW LIGHT ON PLANT GROWTH(2021年)

As a professional grow light manufacturer, ENLITE ENERGY INC provides a lineup of commercial grade Full Spectrum LED Grow Lights for indoor farming, commercial vertical farming and greenhouses.

The plant light time is the time when the plant receives natural light or artificial LED plant grow light. Both light intensity and light quality have their own changing laws, and the same is true for light time:

(1) Light time in summer is longer than in winter;
(2) Day and night are equal all year round near the equator;
(3) Days are longer than nights in summer;
(4) Nights are longer than days in winter.

1. Long-day plants: refers to plants that require a long light time. Only when the long light time is regularly reached during the photoperiod, the plants will bloom and bear fruits, otherwise they will only grow normally and will not form flower buds. Insufficient lighting time for plants has a great impact on them, and it is also the plants that most need to use LED plant grow light to align and fill light.

2. Short-day plants: refers to plants that bloom only when the light period is less than a certain value according to the regular photoperiod, which is the opposite of long-day plants. These kinds of plants generally don't need LED plant grow lights to fill light except for special purposes!

3. Intermediate sunlight plants: This type of plants do not have strict requirements on the light time. It can bloom only if other external conditions are met. Different sunlight lengths have little effect on their flowering, but the light time will affect the growth rate. Using LED plant grow lights can appropriately shorten the growth cycle.

It is very important to understand the light time (the length of sunlight time) required by various plants. Correctly grasping the photoperiod phenomenon of plants can help make targeted adjustments to the growth of plants, use LED plant lights to supplement light, and increase crop yield and quality.

SOME BASIC INFORMATION ABOUT LED PLANT GROWTH LAMP(2021年)

enlitehorti — 2021-12-23T16:49:59+0900

https://www.enlitehorti.com/

As a professional grow light manufacturer, ENLITE ENERGY INC provides a lineup of commercial grade Full Spectrum LED Grow Lights for indoor farming, commercial vertical farming and greenhouses.

The five essential pillars for plant growth are temperature, moisture, nutrition, air and light. As the saying goes, everything depends on the sun to grow, but what should we do if we encounter severe weather such as haze and rainy days? plant grow light can replace the sunlight to give plants an environment for growth and development.

1. Illumination time of the LED plant grow light
However, just like people, plants need exercise, work, and rest. Therefore, you must control the time when you use LED plant grow lights to fill the plants with light. Generally, it is recommended that the plant's light time be controlled between 12-16 hours. In order to leave enough time for the plants to rest, to ensure the efficiency of the plants to work every day.

2. The effect of LED plant grow light quality on plants
The quality of light also has a very obvious impact on the growth of plants at various stages. For example, flowering and fruiting plants need sufficient red light when they are flowering and fruiting. If the red light is not enough, no matter how great the light intensity is, the desired effect will not be achieved and the flowering and fruit setting rate of plants also will be affected.

If the various lights of the plants can be matched in proportion to supplement the light according to the needs of the plants, the effect will be completely different, which will not only shorten the plant growth cycle, but also increase the yield and quality of the plants. This is also the reason for the emergence of plant grow light, and it is the reason why LED plant grow light replaces traditional plant grow light. When the time and light quality are reasonable, it is necessary to use LED plant grow lights to control the light intensity. If the light intensity is not enough, the photosynthesis and respiration of plants will not even reach average, and it is even impossible to grow.

If the light intensity is too strong and it exceeds the light saturation point too much, it is a waste of electric energy and is not necessary. Therefore, the most ideal value state is to control the light intensity around the light saturation point so that the plants can grow healthily and at the fastest speed.

HOW TO GROW VEGETABLES IN VEGETABLE GREENHOUSES WITH PLANT GROW LIGHTS?(2021年)

enlitehorti — 2021-12-23T16:49:36+0900

https://www.enlitehorti.com/vegetable-grow-lights/

As a professional grow light manufacturer, ENLITE ENERGY INC provides a lineup of commercial grade Full Spectrum LED Grow Lights for indoor farming, commercial vertical farming and greenhouses.

1. Factors affecting vegetable greenhouses
(1) Vegetables are also plants. Photosynthesis is required for plants. Different varieties of vegetables have different requirements for light, and vegetables have different requirements for light at different growth stages. There is no adequate lighting environment, plant lights do not have a reasonable light ratio, daylight and artificial plant lights do not have a good combination of supplementary light, which is one of the main reasons why the yield and quality of greenhouse vegetables cannot be improved.

(2)Unreasonable vegetable varieties and planting structures in greenhouses are also important factors in causing losses. Different vegetable varieties have different market demands. Some varieties lack competitiveness and have no market potential; more importantly, different vegetables have light demand. They are also different, and it is inevitable that these factors can cause losses if they are not well grasped.

(3) Obstacles to the air circulation in the shed are another factor causing losses. The lack of air circulation will lead to inappropriate temperature in the shed, too high concentration of harmful gases, and too high carbon dioxide concentration will not only make vegetables can not grow normally, but also inhibit plant growth, or cause plants to wither and die.

2. Vegetable greenhouse solution
(1) Whether the lighting environment is reasonable is one of the important reasons that affect the harvest of vegetables in the greenhouse. Best LED grow lights for vegetables will photosynthesize, absorb carbon dioxide, exhale oxygen, and accumulate organic matter; in the absence of light, they will perform respiration, absorb oxygen, exhale carbon dioxide and consume organic matter. When the two balances are equal, the light compensation point of the plant is reached, and the plant cannot accumulate organic matter to grow smoothly. When the light compensation point is not reached, the consumption of organic matter in the plant is greater than the formation of organic matter, and the plant cannot grow normally and appears sick, withered, or even dead. When the plant is thicker than the light compensation point, the plant grows normally. In the absence of sunlight or insufficient sunlight, LED plant grow lights for vegetables can be used to supplement light to ensure sufficient light environment, combined with carbon dioxide concentration, moisture, temperature, humidity, etc., to allow plants to perform normal photosynthesis to help their growth.

(2) Choose plant varieties to plant according to market demand. Choosing the right plant varieties is the first step to open the market. Reasonably use different types of LED plant grow lights to fill light.

(3) One thing to pay special attention to is that the air circulation problem in the shed, especially in order to save cost, using traditional plant grow lights will produce some harmful gases, which will have a bad impact on the human body. Some traditional plant grow lights will produce high temperature when irradiated, and the temperature in the shed will be too high, which will cause the loss of vegetable water, which is not conducive to growth; some harmful gases such as ammonia, when the concentration of harmful gases produced by fertilizers is too high, it will also produce adversely affect to the growth of vegetables.
