CaptainJack said:not only is hilljack right but what about starting seeds in 12/12...as far as im concerned 12/12 means nothing, i didnt vote because i dont see a place to vote for "when true calyx/hairs start to form/cluster"..
some tropical sativas can be flipped in early veg and not even sex fora couple months more.. they would sex in 24/0 too, and do. this is what i call a reverse auto-flowering mechanism
