Can Grow Light Have The Effect Really?

LED grow light is a kind of grow light, it takes LED (light-emitting diode) as the light source, according to the law of plant growth must need sunlight, with light instead of sunlight to plant growth and development environment of a lamp.
Red orange yellow green cyan blue violet, the wave length of backward light is shorter, wave length is longer to be able to promote plant growth more. Pink light is long - wave light, can promote plant growth, to achieve the effect of supplementing light.
The composition of light is very complex, plants have evolved for so long, each of the components of light have been adapted, there are needs and dependence, so you buy a supplementary light lamp may only supplement one aspect, how artificial light is impossible to completely imitate the effect of natural sunlight on plants. Like again good perfume maker division also cannot imitate completely to make the perfume that has natural orchid faint scent, the best stylist and maker division still is nature.
Light will inhibit internode growth of plants, and this effect will be enhanced with the increase of light intensity and light time. Therefore, seedlings are prone to internode growth and short growth under weak light and short light time, and shorter growth under strong light and long light time. In addition, different light quality will also affect the growth of seedling stem. Generally, red and orange light is the most effective light for photosynthesis, which can accelerate the growth rate of seedlings, but the internodes are long and the stem is thin. Blue violet light can make the seedling grow short and strong, and ultraviolet light has the strongest effect on inhibiting seedling growth and promoting seedling short and strong.
LED grow lights are indeed effective. Red light can promote the rooting of stem segments, chlorophyll formation, carbohydrate accumulation, absorption and utilization. The advantage of plant growth lamp is that it can artificially control the light quality, light intensity and light cycle, so that plants are always in the best growth environment, can improve the quality and increase the yield.
