I found that reducing the time that the lights are on continuously has the greatest impact, although reducing overall time is definitely in order. 3 cycles of 2 on, 2 off will be more effective than simply reducing to 6 straight hours.
Yes I agree that a split photoperiod is another tool to use, a total of 6 hours a day should be the max.
3 on rest 3 hours on
2 on rest 4 hours on
etc.
