I donâ€™t know if it will make a big difference with algae, but Iâ€™ve got my wrgb set up so itâ€™s a little more blue dominant in the am and slowly shifts towards red in the pm. Light comes on at 8am, the blue channel peaks at 60% at 10am (red is at 40%). By 6pm, the red is peaking at 60% and the blue is down to 40% so the program kinda looks like a stretched out â€śxâ€ť between the red and blue channels. Lights off at 7.
I keep the whites and greens constant throughout the day (green 50%, white 30%)
Obviously have to adjust the power so itâ€™s appropriate for the plants youâ€™re growing, but I think youâ€™ll be happy the spectral shift from blue to red dominant throughout the day- it mimics natural shifts that happen with the sun each day, it looks nice, and my plants and fish all responded well to it.
I donâ€™t think itâ€™s a big deal at the end of the day but itâ€™s one more thing you can do to mimic natural conditions.
