If Time > 08:30 Then LT2 ON
If Time > 12:01 Then LT2 OFF
If Time > 16:00 Then LT2 ON
If Time > 18:01 Then LT2 OFF
If Time > 20:00 Then LT2 ON
If Time > 22:00 Then LT2 OFF
If Time > 12:00 Then LT1 ON
If Time > 16:00 Then LT1 OFF
If Time > 18:00 Then LT1 ON
If Time > 20:00 Then LT1 OFF

LT1 is halides, LT2 is NO atinics.

That makes alot of sense. I am going to start splitting up my MH photo period as well.

An easier way to increase the photoperiod is

MH ON at 12 PM
MH OFF at 4 PM
MH ON at 6 PM
MH OFF at 8 PM

Then decrease the amount the MH are off in the middle by 30 minutes every 3-4 days. You should have no bleaching problems.

Acros will peak out on the light in about 4 hours, shutting the lights off at that point lets them rest a little before the lights are back on. Slowly bring the lights back on earlier will help them get used to more light without them bleaching.

I've done this many times and never had problems using this method.

Actually since you are going to 8hrs from 6hrs, I would shut off the lights at 5 PM and slowly work off that 1 hour the lights are off.
