Can led lights really fill the plants?
First of all, we should realize that the effect of the fill light is limited to fill light, and it is not a substitute for sunlight.
Some of the flowering homes are not ideal for lighting, trying to fill the plants with light and add light to the plants. However, this method of replacing the sunlight with light has also been questioned by many flower friends. This article has carried out relevant experimental research on this issue to verify the scientific nature of this practice. It is only for reference. Please forgive me for the inadequacies. For the flower friends, it is very valuable.
The effect of the fill light is to fill the light on a cloudy or long-term exposure to light. The fill light does indeed add a certain amount of light to the plant. But here is to remind everyone: the so-called fill light, as the name suggests is just a supplement, not a substitute for the sun. If you can replace the sun, you should call it "the light."
Many friends say that the effect of the fill light is not good. In fact, a big part of it is that the method of using the lamp itself is wrong. The fill light is not open indoors for 10 hours or outdoor nights for a few hours, or 24 hours. The correct way to use it is to turn it on and turn it off within 2-3 hours. Plants also need time to work. In addition, the reflector is particularly important to provide refraction of light. There is also the distance problem. The distance requirements for various lamps and plants are different. You have to ask the merchant carefully. Here are some common fill lights for you.
1, LED lights
LED plant growth lamp adopts the principle of semiconductor illumination. It is specially used for plant and flower production such as flowers and vegetables. A plant growth aid lamp combined with high-precision technology, general indoor plant flowers, will grow worse with time. The main reason is the lack of light. The irradiation of the LED lamp, which is suitable for the desired spectrum of the plant, not only promotes its growth, but also prolongs the flowering period and improves the quality of the flower. Further applying this high-efficiency light source system to agricultural production such as greenhouses, greenhouses, etc., on the one hand, can solve the drawbacks of the lack of sunshine, causing the decline of the taste of tomatoes, cucumbers and other greenhouse vegetables. On the other hand, it can also make winter greenhouses and fruits and vegetables in advance. It will be listed before and after the Spring Festival, so as to achieve the purpose of anti-season cultivation.
Inadequacies in the spectrum
LED plant fill light, the spectrum is limited to the visible part, mainly composed of red light and blue light, showing pink light, low color rendering, which is not conducive to the protection of vision, especially in the long-term pink light environment, easy to make People are dizzy and sick, and their vision is declining.
In the spectrum of LED plant fill light, there is almost no ultraviolet light, but ultraviolet light plays a role in improving the vividness of flowers. The reason why the flowers in the plateau area are particularly bright is because of the rich ultraviolet radiation.
In addition, ultraviolet light can promote the synthesis of sugar, and increase the sugar content of plant-specific berry plants.
This light is really noble. Count the most expensive lights I have tossed. Prices vary in size. I have bought more than 500 in general. This item is called the little sun. The effect is really the best, really count for a penny. At the time of the experiment, my Ji Yulu was grayed out indoors. All kinds of plants can be used in the absence of sunlight, of course, without watering. One watering my Tian Lifeng became a morning glory. Light belongs to natural light and the eyes will not be uncomfortable.
This light uses a set of combination lights. The overall effect is slightly worse than the gas lamp. However, it seems to have a little effect on coloring. I don't know if it works in my heart. In addition, the illumination area is not large, and the light will not make the eyes uncomfortable. The lamp is also a lot of fake, and it is not convenient for outdoor use. The reflector effect must be configured to achieve the best. In general, it is a good light.
Once there was a great god who wrote a science poster in the post. Then the Lord is very naive to try. Usually this lamp buys a reptile lamp. As for this light, there are many cows B. The reptile box forgot to turn off the reptile. Everyone thinks about it. UV rays are needed for flesh. But it is not so strong. My experiment usually lasts for 2-3 hours. I don't remember closing it once. As a result, the foliage of the plant under the lamp was injured. Plants are awkward. So it was abandoned directly. In addition, I checked the domestic UVB lamp fraud. And it hurts people's eyes and body. When using it, it is best not to be nearby. The eyes will be very uncomfortable when illuminated by the lights. It is extremely inappropriate to use this light.
This should be regarded as a relatively hot light sold by Taobao. The price is also good. The lamp is hot. The bulb is also big enough. But the light makes people's eyes very uncomfortable. It is worth mentioning that a friend of 12 I recommend this light. A astigmatism effect can be achieved. My jade dew was illuminated by this light and the window was bright. The effect on Sedum is not too big. Don't leave when people are nearby. The eyes will be very uncomfortable.
Finally, emphasize again: the fill light is a supplement. It is not a substitute for the sun. It is only a cloudy or growing season that provides auxiliary light. I hope everyone can use it.
