yeah they need MORE than 6 hours of darkness to trigger the hormone, i would say 12 hours of total darkness...unless you have self flowering ones.
Pothead4204life Reviewed by Pothead4204life 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
