PPFD intensity affects the photosynthesis of plants. In a certain range (below the light saturation point), the higher PPFD, the higher the photosynthetic rate and the higher the plant yield.
* Light compensation point: refers to the light intensity of a plant under a certain light intensity, leaf photosynthetic rate and respiration rate are equal, net photosynthetic rate is zero (organic matter formation and consumption are equal), light intensity is called light compensation point.
* Light saturation point: when the light intensity of plants reaches a certain value, and then increases the light intensity, the photosynthetic rate does not increase, which is the phenomenon of light saturation.
Light intensity design
PPFD value plays a very important role in plant growth.
