Is Higher Wattage Better for LED Grow Lights?

No, higher wattage does not mean better. Though higher watts lights have higher intensity, it is preferable to use an LED grow light that matches the plant’s photosynthetic light intensity rather than one with a higher wattage.

The amount of light energy needed by plants at various growth phases to function efficiently might vary based on the plant strains, the size of grow tents, and the like. For instance, 150-watt LED grow lights cannot support cannabis growth, and 800-watt LED grow lights cannot sustain succulent growth.

Generally speaking, plants require more light during the vegetative phase and less light during the flowering phase, although the precise wattage required in practical situations is uncertain. Conditions including temperature, carbon dioxide concentration, and light intensity all have an impact on how photosynthesis progresses. Insufficient light intensity will slow down photosynthesis when other requirements are met. When the intensity reaches a certain point, even if the light intensity is increased further, photosynthesis will not grow if other requirements are not met.

When choosing LED plant lights, the higher the wattage is not necessarily better; instead, choose the grow light that corresponds to the ideal light intensity of the specific plant. The higher watts LED plant lights, the more power will be spent. At the same time, when providing light for your plants, we should also pay attention to other conditions required for photosynthesis, so that it can save energy, but also meet the progress of photosynthesis, and ensure the healthy growth of plants.
