How to choose suitable LED plant lights for plants and seedlings? This is a problem that both junior growers and experienced growers must pay attention to. Appropriate LED plant lights can give seedlings and plants a better growth environment and supplement light. We can start from the following points.
1. Planting environment When choosing the supplementary light, you should choose the appropriate supplementary light according to the planting environment. If it is planted indoors, when choosing the 1000wled plant supplementary light, you must choose the full-spectrum LED plant supplementary light, red The blue light fill light is harmful to the human body and will make people dizzy and nauseous for a long time. Outdoor or in a greenhouse with high humidity, you should choose a waterproof LED plant supplement light lamp, which can extend the life of the LED plant supplement light lamp and ensure normal use.
2. Crop types Different crops do not require light. For wild vegetable crops, we can choose to use full-spectrum fill light, which is reasonably priced and sufficient to achieve the fill light effect. For fruits and crops and flowers, you can choose red and blue light supplement light, which has a good supplement light effect in promoting the growth of stems and leaves, flowering and fruit, preventing overgrowth and coloring.
3. Crop growth requirements When selecting the power of the supplement light, the supplement light of the appropriate power should be selected according to the requirements of the crop for the light intensity and light time. Crops with long light need long-term supplement light. Long-term use will shorten the service life of the supplement light. Therefore, when choosing, pay attention to the warranty period of the supplement light to ensure the service life.
4. Supplementary lights merchants When choosing supplementary lights, in addition to paying attention to their own needs for supplementary lights, they should also pay attention to the strength of the 1000wLED plant supplementary lights. Competent fill-light vendors have guarantees on the quality and price of fill-lights. For example, LED plant supplement light manufacturers will absolutely strictly control price and quality to ensure the effect of supplement light.
LED plant light red and blue lamp beads ratio layout
All the plans of LED plant lights must be customized around plants. What kind of shape the plants need to grow into is cultivated according to the needs of people. Therefore, when looking at the ratio of red and blue beads of LED plant lights, the plant must be considered first. Growth needs and human needs.
But from the perspective of light, whether it is the demand for plant growth or human demand for plants, the control methods include control of light quality, control of light intensity, and control of light time. Only in this way can the light intensity reach the point required by the plant, and the light time can reach a certain length of time, giving the plant a better growth state.
When LED plant lights are used to supplement light to plants, the source of most of the light for plant photosynthesis is LED plant lights. The different light qualities of LED plant lights have different physiological meanings to plants. LED plant lamp lamp beads chips are mainly red lamp beads, blue lamp beads, and full-spectrum lamp beads. The main function of red light on plants is to adjust the photoperiod of plants, and the main function of blue light is to affect the movement of leaves and plastids, to a certain extent Inhibit the flowering and fruiting of plants; the main band of full-spectrum lamp beads is also the red and blue spectrum.
Spectrum: When using LED plant growth lights to grow plants, red light and blue light are very important. It is necessary to look for blue in the range of 440-470nm, and red in the range of 610 to 720nm. These two stages of the spectrum affect the photosynthesis of plants The contribution is the greatest, and other lights also have a weak effect. A better choice is the full-spectrum LED plant light, which can meet the spectrum required by each stage of the plant and can also be adjusted, which can give plants better growth.
Output: This is one of the most important characteristics of LED plant growth lights, and it will affect plant yields. When reading the product description. Will introduce the power of the LED plant light, it can be 400W, 600W, 800W or even 1000W. Generally, it is not always possible to obtain 100% power, and usually the final wattage is low.
Lens: Good-quality LED plant growth lights have an optical lens that can magnify the light and provide about 25% of the nutrient penetration for plants. This makes LED grow lights more expensive, but they are definitely worth the money.
Heat dissipation: LED plant growth lights usually work around 15 hours a day, so you need to ensure that they dissipate heat well, and try to use integrated die-cast aluminum alloy instead of fans or other plastic materials.
Warranty: Look for LED plant growth lights with at least five years of warranty, because this is the guarantee given by powerful manufacturers. The ideal life of LED plant lights is 50,000 hours, which is about 10 years. However, considering various factors, the actual working life will be about 5 years, so a 5-year warranty is the best choice.
Pay attention to the misunderstanding:
(1) The life of LED plant lights is not equal to working time
The lifespan of LED plant lights from most manufacturers can reach more than 50,000 hours. This life is the theoretical life that the lamp can use. The factors of light decay and technology replacement are not explained.
The light decay of LED plant lights includes many aspects. On the one hand, it is the lamp chip itself, the brightness of any lighting lamp will decrease after a long time working. On the other hand, accessories, including wires, panels, lenses, covers, etc., will age after a long period of time. Even if a new LED chip is replaced, it is impossible to achieve the best plant lighting effect as before.
(2) The higher the power, the greater the brightness, the better the effect
Power refers to the power consumption of the LED plant light in a certain period of time, and has no direct relationship with the light supplement effect of the LED plant light. The key factors that we should pay attention to are workmanship, quality and effectiveness. Brightness is the definition of light perception by the human eye. The perception of light by plants is calculated based on the illuminance lux. It is not that the brighter the human eye feels, the better the effect of LED plant lights. We'd better choose different LED chip ratios according to different stages of plant growth to achieve the best growth of plants at different stages.
(3) LED plant light is a cold light source, it will not burn plants
LED plant lights are cold light sources, compared to other plant growth lights. All products related to electricity generate heat. At present, there is no photoelectric conversion source that can achieve 100% photoelectric conversion, and more or less of the electric energy will be converted into heat energy, and the same is true for LED plant lights.
Low-power LED plant growth lights can illuminate plants at a close distance, especially during the germination stage. However, if the 600wLED plant growth light is attached to the plant, the heat radiated to the plant for a long time will also burn the plant. When the power is high, you must use an air conditioner or fan to dissipate heat.
Hope this can help you choose a good LED plant growth lamp and give plants better light.
