15% on whites and 65% on the blue. Lights are on for 12 hours. 1 hour ramp up and a 1 hour ramp down. My blues were at 75 and had to turn them down a tad. I have a 18" sbreef extreme wifi or something like that.
Ok,Thanks! my light can't ramp up and down automatically,it just has a LCD Screen for setting the times for ON/OFF,but it has both dimmers,one dimmer is for blue channel,another dimmer is for white channel.
