I actually run a 9.5 hr cycle.

4pm- dawn cycle
5pm - full lights
1030-130 - dusk


It is supposed to start at 3pm and off at 1230am, but too lazy to change my timers to DST.

I love the dawn and dusk cycle... Colors just pop.

With the new LEDs, I will probably be extending my photoperiod to over 12 hours altogether.

When I set up a different timer for the blues, it will be 15 hours of blues (8x10w @100%) and 12 hours of whites (12x10000k, 3x20000k & 3x6500k @ 70%). So an hour & a half of dawn & dusk effect each.

I have halides and no chiller, so winter is 12 hours, summer 8. It slowly changes throughout the year to get there.

I voted wrong. Should have been 10 hours. Forgot to include dawn/dusk :) I was just thinking Halides.

I did the same, but I have a single actinic for dawn/dusk, I can't count that as light. It's on 8am to midnight..

My dawn/dusk is handled by the seasonal programming built into my apex but it basically varies it from 11 to 13 hours total over the year. I run my MH for a constant 9h/day throught the year.
