Sounds like theyre beginning their stretch. Many plants begin their flowering cycle at substantially shorter dark periods than 12/12 In the Southwest flowering often begins at 14+ hours of light. (I can't back it up scientifically, but I think it has something to do with the intensity of the light.) The change is much more gradual than putting them into a 12/12 . What is your average frost date?
BosqueBoy Reviewed by BosqueBoy on . question about outdoor photoperiod What hour set does the photo period kick in and tell the plant its time to flower ... just checked the sunrise / sunset times for my area and they tell me that it turns 12/12 on Sept 25 ... with flower times running 6-8 weeks on average, that means the harvest would be ready in November ... that doesnt sound correct ... first frost usualy happens in Oct ... "on paper" my plants dont stand a chance ... but many people grow weed out side in New Englnd with success ... we are currently at 13/ Rating: 5
