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.

no idea what you're talking about :)

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.

8hrs daylight only plus a couple for actinics

14 hrs.

15hrs total DIY LED
1.5 hrs dawn and 1 hrs dusk

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

10 hrs. Halides are only on for 7.

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..

T5's on at 08 and off at 22
MH on at 12 off at 20

I'm trying to find the best cycle aswell... What are the Benifits to a longer day vs a shorter day?... I will have 4 t5 ho 2 are blue and 2 are white

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.
