Yes... your second guess is correct. And, those time windows are often overly idealistic. The real time it takes depends mightly on the grower and grow conditions -- always longer. I just offer that up cuz I see a fair number of posts where people say.. "I know I shouldn't chop just yet, but we're moving and the Seed Co. said 9 weeks, and now it's 12... and they still need two more.." Etc.
