Can lighting really replace sunlight for plants?

Some flower friends' home lighting is not very ideal, trying to supplement light to plants through lighting and increase light to plants. However, this practice of using light instead of sunlight is also questioned by many flower friends. This paper has carried out relevant experimental research on this issue to verify the scientific nature of this practice, which is of great reference value for flower friends.

Can lights really add light to plants?

The function of the supplementary light lamp is the supplementary light measures taken in cloudy days or when there is no light for a long time, and the supplementary light lamp can indeed supplement a certain amount of light source for the plant. But here is a reminder: the so-called replenishment of light, as the name implies, is just a supplement, not a substitute for sunshine. It should be called "substitute light" if it can replace the sun.

Many friends say that the effect of supplementary lights is not good. In fact, a large part of it is the wrong way to use the lamp. Supplementary lights are not turned on indoors for more than 10 hours or outdoors for a few hours at night, or 24 hours a day. The correct way to use is to open at dawn and close within 2-3 hours after dark. Plants also need time to work and rest. In addition, the reflector is particularly important, providing the refraction of light. And then there is the question of distance. The distance requirements for all kinds of lights and plants are different. You should ask the merchant carefully about this. Next, I would like to introduce to you several commonly used supplementary lights.

1. LED lamp

Maybe this lamp is only suitable for growing vegetables. Saving electricity is quite energy-saving. The master also specially made waterproof lamps. The cost is not low. The style is noble and big. The light is worse than the chiming light. I put it on the windowsill, just like the red light district at night. Sometimes I don't remember shutting down the person on the other side and saying that it was scary at night. The lamp is a complete pit. But growing vegetables must be a good thing. Forget about succulent plants.

2. Xenon lamp

This lamp is really noble. It's the most expensive lamp I've ever had. Prices vary from size to size. I bought a regular one, which is more than 500. This guy is called Little Sun. The effect is really the best, it really counts as a penny of the goods. At the time of the experiment, my Ji Yulu was gray in the room. All kinds of plants can be used without sunlight, of course, without watering. As soon as I watered my Tian Lifeng, she became morning glory. Light belongs to natural light and the eyes will not be uncomfortable.

3. Happy Wannian photosynthetic Star full Spectral Lamp

This lamp uses a set of combined lights. The overall effect is slightly lower than that of xenon lamps. But it seems to have some effect on coloring. I don't know if it's in my heart. In addition, the exposure area is small, and the light will not make the eyes uncomfortable. There are also a lot of fake lamps, so it is not convenient to use them outdoors. The reflector must be configured to achieve the best effect. All in all, it's a pretty good lamp.

4. UVB lamp

There was a great god who wrote a science post in the post bar. Then the Lord was naive enough to try. Usually this lamp is bought by reptile lights. As for how awesome this lamp is. If you forget to close the crawler box, it will kill the reptile. Just think about it. Ultraviolet rays are needed for succulent plants. But it doesn't have to be so powerful. My experiment usually runs for 2-3 hours. I don't remember turning it off once. As a result, the leaves of the plants were hurt under the lamp. The plants are dying. So I just abandoned it. In addition, I checked the number of fake UVB lights in China. And it does great harm to people's eyes and body. It's best not to be around when using it. The eyes will be very uncomfortable by the light. People are not recommended to use this lamp.

5. Chiming plant supplementary lights

This should be regarded as a popular lamp on Taobao. The price is also good. It's just the lights are hot. The light bulb is big enough. But the light makes people's eyes uncomfortable. What is worth mentioning is a kind of 12 friends. I recommend this lamp. Astigmatism can be achieved. My jade dew was illuminated by this lamp and the window was bright. It does not have much effect on the anti-apprentice of Sedum. Don't drive when people are around. It's hard for your eyes.

Finally, I would like to emphasize once again: the supplementary light is to make up. Is no substitute for sunshine. It's just auxiliary light on cloudy days or growing seasons. I hope you can use it.
