Excessive light intensity may damage plants

Excessive light intensity can indeed damage plants, which is usually reflected in the following aspects:


Leaf burn:

When the light intensity is too high, plant leaves may burn. This is because too much photon energy causes the temperature of the leaf surface to rise, which damages the plant tissue.

Increased transpiration:


High light intensity increases plant transpiration, resulting in accelerated water loss. If the water supply is insufficient, the plant may become dehydrated, which affects its normal growth.

Photoinhibition:

Photoinhibition refers to the phenomenon that photosynthesis is inhibited due to excessive light. This causes the photosynthetic efficiency of plants to decrease, which may affect growth and development.


Leaf bleaching or wilting:

Excessive light can destroy chlorophyll, causing leaf bleaching, and even browning or wilting.

To avoid these problems, growers need to correctly adjust the height and light intensity of LED grow lights to ensure that plants can receive the right amount of light. Usually, adjusting the distance between the lamp and the plant and using dimming functions to control light output are common solutions.
