Is LED plant grow light useful?
LED plant growth light is a kind of plant light. It uses LED (light-emitting diode) as the light source. According to the law of plant growth, sunlight must be needed, and light is used instead of sunlight to give plants growth and development environment. A kind of lamp.
Red, orange, yellow, green, blue, blue and purple. The further back the light, the shorter the wavelength, and 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.
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.
LED grow lights are really effective, and red light has the effect of promoting rooting of stem segments, chlorophyll formation, carbohydrate accumulation, and absorption and utilization. The advantage of plant growth lights is that they can artificially control light quality, light intensity, and light cycle, so that plants are always in the best growth environment, which can improve quality and increase yield.
