How to Induce Flowering. Because of photoperiodism, you can easily induce flowering in cannabis plants simply by changing your grow room light cyclesâreducing the light from 18 hours a day or more, to only 12 hours each day.
Plants can be classified into three categories, depending upon their flowering response to the duration of darkness. These are short-day, long-day, or day-neutral plants. Short-day, (long nights) plants form their flowers only when the day length is less than about 12 hours in duration.
