NOBODY can tell you the strain, for sure ... from your photos, I would say it is a roughly 50/50 sativa/indica hybrid ... if I'm not mistaken, Big Bud is a predominant-indica, so that wouldn't be the strain ... they look about right for 36 days of flowering, yup ... with fluorescent tubes, you should have your lamps about one inch above the plants, you're too far away, in the photo ... :smokin:
