When the LED grow light does not appear, it is precisely when the plant light does not appear, that is, when everything grows by the sun, and the growth of plants is inseparable from the surface.

      Because of relying on sunlight, plants can only grow in the open air at first. Because of many uncontrollable factors in nature, the quality and yield of crops are full of uncertainty. Hence the emergence of greenhouse cultivation.

      Greenhouse planting is a good solution to a series of uncontrollable growth conditions of plants in the open air, such as temperature and humidity suitable for plant growth and carbon dioxide concentration, one of the raw materials for plants to accumulate organic matter in photosynthesis, and so on.

      Humans are always facing problems, and yet humans are always solving problems.

      As the world's population grows and the area of arable land declines, people also realize the seriousness of the food crisis. But people always need food. However, the population is increasing, the arable land is getting less and less, and the farmers are getting less and less. These are the results of social development, which will not be reversed and cannot be reversed. The only solution can only be to improve the efficiency of farming and increase the yield and quality of farming.

      The concept of three-dimensional planting has gradually emerged. The so-called three-dimensional planting is multi-layer cultivation. Originally, only one layer of crops could be covered on the ground. Using three-dimensional cultivation can realize multi-layer planting. Simple three-dimensional planting can be as big as building a skyscraper to form a three-dimensional planting plant factory.

      To achieve three-dimensional planting, the biggest problem is the light required for plant photosynthesis. Sunlight can only achieve one layer of planting. Even if mirror reflection is used, the area is too large and the number of layers is too large. need.

      Since natural light cannot meet the demand, it can only be supplemented by artificial light. Plant lights came into being. Incandescent lamps to halogen lamps, and then to sodium lamps to fluorescent lamps, although various attempts and applications are progressing, but there is no plant lamp that can not only ensure light efficiency, but also save energy and protect the environment. It was not until the rapid development of LED technology that LED plant lights were invented and applied, and the concept of three-dimensional planting was put on the table again.
