Why the red light more than blue light in LED Grow Lights

Many people have a such question is that why almost all the LED plant lights on the market are purple with the naked eye? Is most of the purple light used? In fact, the reason for the purple light is due to the superposition effect of red light and blue light. Generally speaking, the proportion of red light will be higher than that of blue light.

Why is the proportion of red light in LED plant lights more than that of blue light?
1. During the growth of stem segments, the effects of natural light and red light on plant growth were compared. Under natural light, the chlorophyll content decreased first and then increased. However, the chlorophyll content under red light was higher than that under natural light, indicating that red light showed a significant promoting effect on the formation of chlorophyll, and this result became more pronounced with the increase of culture days. 
2. The growth potential of the plants under red light is better. It may be due to the higher chlorophyll content in the plants, more vigorous photosynthesis, more synthesis of carbohydrates, thus providing sufficient material and energy for plant growth.
3.The content of soluble sugar in the 7th day of culture was lower than that on the 13th day, and the red light decreased more than that under natural light. The rooting of stems under red light was also earlier than that under natural light. After 13 days, the soluble sugar content under red light is higher than that under natural light, which may be related to the higher chlorophyll content under red light and more vigorous photosynthesis. 
4. The activity of NR in stem segments under red light was significantly greater than under natural light, and red light could promote nitrogen metabolism in stem segments. Red light has the effect of promoting stem rooting, chlorophyll formation, carbohydrate accumulation, and absorption and utilization of plants. In the process of rapid propagation, the use of red LED plant growth lights to fill light to promote the rapid rooting of various plants and improve the quality of seedlings.
