I have been running the gen 3 at about 80% with the radiant color mode but haven't liked the results. So i altered the programming a bit. I'll post mine, and if you run something custom please post it up. Mine is quite simple. I have a start point, mid day, and end point. I run a 12 hour schedule. And mid day is the high point. At mid day this is my percentages. UV 15% Royal Blue 100% Blue 100% White 30% Green 10% Red 10% The reason I went with these is that my acros seem to be losing color. I felt maybe running white and UV too high was stressing them out. And also I kinda hoped running more blue would help better my colors as well.
