Plants have an optimal intensity of light. The process of photosynthesis is maximized and plant growth is greatest at this optimal intensity. If the level of light is less, growth is reduced. In a typical plant, light level of 400 foot Candle is just enough for the rate of photosynthesis to equal the rate of respiration. This is called the light compensation point. At this intensity, there is no net growth, but the plant can survive. Therefore, checking the light intensity is important for proper plant growth. The control of light intensity allows grower to achieve the desired growth in plants.
