So I've tried to do some research of my own but I couldn't make sense of the articles filled with tons of technical terms. The MingDak "Aquarium Full Spectrum Light" I ordered arrived today and works great. On this light there is a switch that changes the combination of LEDs that are on. The first setting is all LEDs are on (Red, White, Blue), the second setting consists of The white And red lights (which displays at more of a green color), and the third setting is just the blue lights. My question is, What are the different colors for? Do they grow plants better or are they just there to mimic different types of sunlight? I'd appreciate any answers, thank you!
