Aquarium lighting plays a big part in plant health. Your LED light should stay on for approximately 6-8 hours a day to mimic natural sunlight. A light that is too weak or too strong can actually damage some plants, or cause algae to bloom. There’s also a particular wavelength (also known as spectrum) of lighting that plants prefer. Getting an aquarium light specifically designed to grow aquatic plants will definitely help in the long run. A light that allows the users to control the brightness would be ideal. If the light ends up being too bright, you’ll have the option to dim it.
