Based on scientific research and studies, it can be concluded that blue and red light in the visible spectrum tend to have the greatest impact on plant growth. Blue light is essential for the growth and development of leaves and stems, while red light plays a key role in flowering and fruit production. Green light is the least absorbed by plants and is generally reflected, which is why plants appear green to our eyes. Overall, blue and red light are the most important colors in the visible spectrum for promoting plant growth.
