Yaorong tells you the advantages and disadvantages of led plant growth lights
The rapid growth of plants and the harvest in the greenhouse require more than water and soil. The proper light level is also very important. Many times growers make a serious mistake, which is to install many HPS lights and bring them close to the plants. The HPS lamp emits a lot of heat. Lights close to plants will burn the leaves. LED grow lights are one of the most promising types of supplementary lighting for greenhouses. Let us understand this in more detail, because this type of light has many advantages over other types of lights, and because it is a new stage in the development of horticultural lighting. . In winter, insufficient light is a serious problem, when the sun is short and the sun is insufficient or insufficient for effective growth. Vertical farms or-more common in Europe-vertical farm containers are good examples of such farms.
But first, why do plants in the greenhouse need LED grow lights?
There are several options for using artificial LED grow lights today:
-Supplement. Promote photosynthesis. In this case, LED plant growth lights are used in combination with natural sunlight;
-Regularly. Supplementary LED plant growth lamp lighting is just to make it possible to control the daylight hours;
-Full daylight alternative. This program maximizes the control of the process of plant growth. It is worth noting that the complete replacement of daylight is only used in rooms with climate-controlled environments. Only by maintaining a balance is it possible to enrich the optimal growth rate of plants.
Before installing LED grow lights in a greenhouse, it is important to figure out its benefits for plants. Let's take a look at the important role of lighting in plant growth.
A complex chemical process takes place in plants: from simple molecules, huge organic chains are constructed to form the plant itself. For any process, energy is needed, and in real life conditions, plants use sunlight to obtain energy. A photon enters the leaf and initiates a biochemical reaction. The result is an increase in weight-roots, stems, leaves and fruits develop. The process of combining the atoms of simple mineral molecules into more complex organic molecules that occurs under sunlight is called photosynthesis. No light means no photosynthesis, and no plants without photosynthesis. The roots do not develop, the buds do not grow new leaves, the buds do not form, and even the fruit cannot even be dreamed of.
Artificial lighting must provide the assimilation lighting required for plant growth. LED assimilation lighting can increase the harvest per square meter and reduce the planting time. The LED plant growth lamp with a specific spectrum is the perfect solution. If the lamp does not solve this problem, it will only emit heat that will harm plants in the future.
Advantages and disadvantages of LED grow lights LED grow lights are on top of the world.
In terms of indoor farming, LED lighting technology has been soaring.
If it has not surpassed the traditional lighting system, it will soon surpass.
LED lights are the technology of the future. Compared with other types of horticultural lighting, they have many huge advantages.
In other words, they also have several shortcomings.
But these shortcomings are disappearing quickly because manufacturers are making their lights more efficient and cheaper. Soon, HID lighting (or other forms of lighting) will do better.
Let's take a look at the main advantages and disadvantages of LED grow lights.
Advantages of LED grow lights
These are the biggest advantages of using light-emitting diode technology to illuminate plants.
Fast harvest cycle
The LED grow light can be used 24 hours a day, and it has little effect on temperature. When growing plants indoors, the lack of environmental feedback means that plants rely on you to tell them what season it is and how they should behave.
The use of LED plant growth lights enables you to change the time of day and the amount of light of red wavelength at the correct time to maximize the growth rate of plants.
When LED grow lights are used to grow automatic flowering plants, there may be multiple harvests in one season. You can change the flowering time of the plant and increase the yield.
Prolong life
The lifespan of LED grow lights exceeds 50,000 hours, which is much longer than traditional lighting systems. An important reason for this is the low operating temperature of the lamp.
Traditional lighting systems generate a lot of heat, which significantly shortens their service life. The longer lifespan of LED grow lights means that you can grow crops for many years without replacing the lighting system, thereby reducing costs.
Energy saving
LED grow lights are more efficient than traditional lighting systems and can reduce energy by 60% to provide the same level of light.
Compared with traditional lighting systems, they emit less heat and provide more usable light. This is because LED diodes will not burn anything to produce light. Due to reduced energy use and heat production, LED plant growth lights greatly reduce energy costs.
Healthier plants
A light source that emits more ultraviolet, infrared, and heat is counterproductive to plant growth. This is because they cause plants to burn and dry up quickly, which causes them to require more water and energy to sustain life.
When using LED grow lights, heat and harmful wavelengths of light are limited. Therefore, water and energy are used to grow and cultivate healthier plants, not just for survival.
Target wavelength
LED plant growth lights allow us to adjust the wavelength of light, which means that we can provide plants with the exact light (action spectrum) needed for photosynthesis.
Traditional lighting systems emit a lot of green and yellow wavelengths of light, and plants do not use these lights. They need green and yellow light, but not so much.
This is a waste of energy.
When using LED plant growth lights, you can provide plants with the accurate spectrum they need. No light will be wasted, you can make full use of your energy.
Full spectrum
The best LED grow lights will produce a balanced full-spectrum light. As mentioned above, they provide you with all the light that plants need, don't look for "fuzzy" lights. The idea that plants only need red and blue light is outdated.
In addition, most lamps allow you to turn off specific wavelengths, so you can produce perfect light for each stage of plant growth. This means that LED grow lights are actually more suitable for your plants than natural light.
Cool working temperature
LED grow lights do not emit a lot of heat. This is different from HID lighting systems that produce temperatures close to 400 degrees or higher.
LED grow lights have little effect on the working temperature of the greenhouse or growth room. There is no need to install a cooling system in your planting area.
Environmental protection
LED grow lights are 100% recyclable. Unlike HID lamps, they do not contain toxic substances such as mercury. To ensure this, all high-quality LED grow lights have passed RoHS certification.
Disadvantages of LED grow lights
Despite its many advantages and growing popularity, gardening LED lights do have some disadvantages.
Generate directional light
LED lamps provide directional light like flashlights. They usually cover an area smaller than that covered by traditional lighting systems. Newer lights have solved this problem.
High purchasing cost
LED grow lights are much more expensive than HID or fluorescent lights. At least it's good.
You can find some lamps that are actually cheaper than HID lamps, but they are not very good.
In other words, there are now several high-quality LED companies selling their lamps at very low cost. You can even buy fixtures for less than $100.
Light pollution
LED grow lights produce bright blue light (among other colors), which can cause blindness in humans.
Affected by heat
LED grow lights are very sensitive to high temperature. Diodes may fail faster at high temperatures, so the quality of the light they produce will be affected.
This is why a good radiator and fan system is an important part of most LED plant growth lamps. In other words, newer plant growth lights, such as those from Shenzhen Yaorong Technology, do not use fans at all. It is completely dependent on passive cooling through a large radiator.
Aging effect
With age, LED diodes may also start to change color. Despite their long lifespan, they may not consistently produce the expected light quality as they age.
For cheaper LED chips, this is even more an important issue. If you buy quality lamps from a reputable company, you don't have to worry about this problem.
Advantages and disadvantages of LED grow lights: final thoughts
LED grow lights are almost certainly the future of the gardening industry. Even today, higher costs are the only serious disadvantage. As prices fall, this shortcoming is quickly disappearing. The best LED grow lights are very effective, and they can easily surpass any other type of garden lighting on the market today.
