Plants like these will flower if taken from 18/6 OR 24/0 down to 14/10.

I know for fact, White Russian (cross breed of white widow / ak47) produce more THC under a 14 hour light cycle.

12/12 is perfectly normal and will induce flowering as well.

Your question still is unclear to me.

It DOES matter how much light they get and the frequency and schedule.

Pick one and go with it.
HARDDON Reviewed by HARDDON on . Specific Question... ive read on here that the plant times the dark time and releases flowering hormones... Can i start the dark cycle early as long as its only for 6 hours or less? In other words... If i had to shut the lights off early in the day cycle, but only had them off for 6 or less hours, then will the plants flower? Peace All Rating: 5
