Will LED grow lights really work?

LED grow light is a kind of plant lamp. It uses LED (light emitting diode) as the light source. According to the law of plant growth, it needs sunlight. It is a kind of lamp that replaces sunlight with light to give the growth environment of plants. Red, orange, yellow, green, blue, blue and purple, the shorter the light wavelength is, the longer the wavelength, the more it can promote plant growth. Pink light is long-wave light, which can promote plant growth and achieve a light-filling effect.

The composition of light is very complicated. Plants have evolved for so long, and they have adapted to each component of light, have demands and reliance on them, so the fill light you buy may only supplement one aspect, and artificial lighting does not matter. It may completely mimic the effect of natural sunlight on plants. Just as the best perfume maker cannot completely simulate the creation of perfume with natural orchid fragrance, the best designer and maker is nature.

Light will inhibit the growth of plant internodes. This effect will increase with the increase of light intensity and light time. Therefore, seedlings are prone to internode growth and lengthy under the condition of low light and too short light time. Under strong light, the internode is shorter when the light time is long. And different light quality will also affect the growth of seedling stems. Under normal circumstances, 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; blue-violet light can make The growth of seedlings is dwarf, and ultraviolet light has the strongest effect on inhibiting the growth of seedlings and promoting the dwarf of seedlings.

LED grow lights are indeed effective. Red light can promote stem rooting, chlorophyll formation, carbohydrate accumulation, absorption and utilization. The advantage of the plant growth lamp is that it can artificially control the light quality, light intensity, and light cycle, so that the plants are always in the best growth environment, which can improve the quality and increase the yield.
