What is your color, violet, red and green set at?Thank you! I use the Kessil Spectral X controller, so I can't share an app setting here. But I ramp up starting at 9 am (15%) to 55% from noon to 4 pm, then ramp down to 0% at 930 pm. Par is about 200 at the top of the tank, and 100 at bottom at peak period. It is a pretty even spread with the 4 lights.
