I'm never really sure about those finish dates myself. Pick a strain and go looking and on one page you can find three different finish times. I always figure I'm in for around 90 days with an auto and about 120 or so with a photoflower. Every grow is different, each plant is different. You can grow two seeds of the same strain and get to completely different harvest times.
So to answer your question.... Who knows?
