The answer to this question is uncontroversial, despite the fact that there is a heated discussion over whether the green light has any impact at all. Yes, blue light is more effective at promoting plant growth than green light.
The chlorophyll is green. They definitely don’t absorb green light because they reflect it. It’s not much, anyway. As a result, green light is relatively ineffective for promoting plant development.
However, this does not imply that green light is useless. Green light is still a component of the light spectrum. They are proven to penetrate a plant’s canopy deeply.
