In other words, everything depends on the sun for growth. What should we do when we encounter such bad weather as fog and haze, cloudy and rainy days? Plant growth lamps can help us replace sunlight to provide the environment for plant growth and development.
The quality of light also has an obvious effect on the growth of plants in different stages. For example, the flowering and fruiting plants need sufficient red light during the flowering and fruiting period. If the red light is not enough, the intensity of light can not reach the desired effect, affecting the flowering and fruiting rate of plants. If the illumination intensity is too strong and exceeds the light saturation point too much, it is a waste of electricity and unnecessary, so the ideal value is to control the light intensity around the light saturation point, so that plants can grow healthily and rapidly.

However, like human beings, plants need exercise, work and rest, so when using LED plant lights to supply light to plants, they should also control the time. Generally, it is recommended that the time of plant light should be controlled between 12 and 16 hours, so as to give plants enough time to rest, so as to ensure the efficiency of plant work every day.
If the plant light can be proportionally matched according to the needs of the plant, the effect will be completely different. It can not only shorten the plant growth cycle, but also improve the yield and quality of the plant. This is also the reason for the emergence of plant lamp, but also the reason why LED plant lamp replaces traditional plant growth lamp.
When the time and light quality are reasonable, it is necessary to use LED plant lights to control the light intensity. If the light intensity is not enough, the photosynthesis and respiration of plants can not reach even level, and it is impossible to imagine the growth of plants.
