Length depends on your strains and I havent grown any of that type so I cant say for sure but you have till the pollen balls burst lol...
Use a magnify glass to get a closer look and look at the pic in the link I provided. As soon as you start 12/12 I would say after a week to 2 weeks any strain should show either male or female signs.
I just started a new grow with all fem strains gonna see if they hermie and have some lowryders ordered gonna check out that 8 week from seed to harvest man that maybe good if the smoke is nice.
Lowryders would probably be the only strain where the week-2 week rule doesnt apply since they autoflower it would be much earlier.
