I live in the center of Wisconsin and I have some concerns about my grow. Obviously mother nature can be a fickle bitch and that's what I'm concerned about. These are my first 2 plants so I'm very much a newbie and I feel like I'm missing something here. If flowering is supposed to start when the days get to 12 hours of darkness (which occurs at the end of Sept.) how are my plants supposed to last through October? Or do plants start flowering before 12/12?
