Growers often use supplemental light to optimize plant growth.

What Colour light is best for aquarium plants?

That being said, we can conclude that the light spectrum that supports the growth of freshwater aquarium plants best should include: At least 50% red light in the wavelength range of 630 to 700 nanometers. At least 35% green light in the wavelength range of 500 to 580 nanometers.
