Plant growth is achieved by storing organic matter through photosynthesis, and light intensity directly affects the strength of plant photosynthesis. Therefore, the light intensity has a great influence on plant growth and development.

Different plants have different responses to the photoperiod. Plants that require 14 to 17 hours a day to flower buds are called long-day plants, such as rape, spinach, and radishes; plants that require 8-12 hours of light per day are called short-day plants. Such as chrysanthemum, rice, soybean, etc. But higher or lower light intensity will have a bad effect on plants.
