hey buddy. herbies big bud #2 is basically an F2 of Big Bud, I only got one keeper male out of 15 of these seeds, but the grow environment got a little unstablish, had some equip failures at the same time so. Very short plants, not too vigorous as seedlings. 6 weeks into flower you should have an idea, Big Bud should be finished in under 65 days flowering, some around 50 days
