three different working modes of plant lights

Grow lights work in three different ways:

Provides all the light the plant needs to grow

· Supplement sunlight in winter when the sunshine hours are short

Increase the length of the "day" to promote special growth and flowering

LED grow lights control plant growth by regulating light. The ability to consistently grow food locally represents a major breakthrough for humanity. Grow lights allow people to grow food indoors, and making the most of waste space is also an efficient way to produce food.

Removing transportation costs from the food chain is also a major breakthrough. The ability to consistently deliver fresh and wholesome food presents a major shift in the way people live and achieve quality of life. Grow lights increase the density of food production by a factor of ten. This has important implications.

In some places, such as Japan, the environment leaves something to be desired. Plant Factories will continue to expand and use LED grow lights to act as large warehouse entities to provide food to the general public and those in need of special nutrition.

Susan Eustis, principal of the research team, said: “Solid-state electronics will bring the same benefits to agriculture as it has brought to other industries. Growers are finding they can realize a quick return on investment, and the use of grow lights can significantly increase the Reduce energy costs, extend growing seasons, eliminate chemical contamination in the food supply and significantly reduce transportation costs for food production."

As more and more people realize the importance of health and try to avoid the harmful effects of pesticides in their food, greenhouse operators are finding more potential markets for grow lights. Large plant factories will focus on raising seedlings.

Whether the plant light is useful or not depends on the correct use of the whole process.

First of all, when choosing lights, you should pay attention to choose LED grow lights according to the needs of plants. If it is a light-loving plant, buying a low-power ordinary plant light cannot meet the growth needs of plants. If it is a shade-tolerant plant, use Plant lights that consume too much energy are not cost-effective; in addition, if you choose LED plant growth lights, you must customize the ratio of lamp beads according to the needs of plants, so that plants can obtain the best growth conditions in the most energy-efficient way.

Secondly, when using plant lights, pay attention to: 1. Switch on and off the plant lights regularly. For example, if the plant is from 9:00 am to 5:00 pm, the sunlight can meet the growth needs of the plant, and the fill light time can be: 7:00 --9:00 and 17:00--21:00; 2. Set a reasonable light distance, too far away from plants, insufficient light, can not achieve the best lighting effect for plants, too close to plants, just Local fill light will cause the plants to receive uneven light, resulting in unpredictable growth conditions.

Finally, pay attention to the maintenance of plant lamps: according to the instructions provided by the merchant when buying plant lamps, installation, inspection and maintenance are not very meaningful in a short time, but if they are not cleaned for a long time, they will not be cleaned in the correct way. The damage is very large.

Are led grow lights useful?

Are LED grow lights useful? Many scientists' studies and many biologists' experiments have proved that LED grow lights are very good light sources for plants.

You should know that red, orange, yellow, green, blue, blue and purple, the shorter the wavelength of light, the longer the wavelength, the better the growth of plants. Pink light is long-wavelength light, which can promote plant growth and achieve the effect of fill light.

In fact, you can use light such as incandescent lamps to illuminate day and night, which is also long-wave light. On the contrary, the light emitted by fluorescent tubes is short-wave light. Use both lights together and you're good to go. In order to welcome the Olympic Games, Beijing used this method to make many flowers bloom earlier.

However, the composition of light is very complex. Plants have evolved for so long, and they have adapted to every component of light and have needs and dependencies. Therefore, the fill light you buy may only supplement one aspect. It is impossible to completely imitate the effects of natural sunlight on plants. Just like no matter how good a perfumer is, it is impossible to completely simulate and create a perfume with a natural orchid fragrance, the best designer and manufacturer are still nature.

Also, different plants have different needs for light.

Light will inhibit the growth of plant internodes. This effect increases with the increase of light intensity and the increase of light time. Therefore, seedlings are easy to grow internodes and grow leggy in the case of weak light and short light time. Under strong light and long light time, the internodes are shortened. And different light quality will also affect the growth of seedling stems. Usually, red-orange light is the most effective light for photosynthesis, which can speed up the growth of seedlings, but the internodes are long and the stems are thin and weak; blue-violet light can make The seedlings grow short and strong, and ultraviolet light has the strongest effect on inhibiting the leggy growth of the seedlings and promoting the short and strong seedlings.

Therefore, if you are a friend who is really interested in plants, or you want your own plants to grow as long as possible, you don’t have to worry about the question of “Is LED grow lights useful?” What you should do instead is to understand plants If you like it, master the correct way to use the light!
