Will plants burn under LED growth lights?

Plants may be ‘burned’ under LED growth lights.

 

Mainly due to two reasons:

One reason is that if the waste heat generated by LED lamps is poorly dissipated, it will accumulate near the lamp beads, causing high temperature burns to plant tissues such as burnt leaves or browning;

Secondly, excessive light intensity (especially high-power LED lights) can exceed the photosynthetic saturation point of plants, causing damage such as light suppression, photo oxidation, or leaf fading.

 

To prevent burns, it is necessary to set the distance, power, and lighting time of the lamps reasonably, and adjust them by checking the reaction of the leaves (such as curling or discoloration) and sensing the temperature of the plant canopy; At the same time, ensure good ventilation to dissipate heat, and use a light meter to monitor intensity to avoid prolonged exposure.

 

Summarize

Although LED growth lights are “cold light sources” with low heat, improper heat dissipation or excessive lighting can still cause plant burns; The key lies in controlling distance, optimizing ventilation, and adjusting lighting parameters based on plant needs to ensure safety.
