Often Indica strains will show sex at around 21 days, in some cases it can be a little earlier.
Sativas may flower a few weeks later.
So how do you know if you have males?
When you are ready to flower flip to 12/12:12-12:
The very first pre-flowers show up in the crook between the main plant stalk and a fan leaf stem , usually near the top of the plant. The good news is, the males usually begin to develop and show sooner than females.

When you see the balls you know you have a male, if your not looking for a breading male, get rid of then ASAP.
You do not want to let them get to the nanner stage!

Once you see nanners, the flowers have opened and pollen could be fly all over the place, seeding your females!
But what if you don't want to get rid of your males and choose one of them to breed with?
Then taking cutting once the plant has reached sex (often around 21 days) Label the Adult plants and then label the cuttings so they match with the parent plant!
Then stick the Rooted cuttings under 12/12:12-12:
You will then see if each plant you took a cutting off of is a male or a female.
Of course you will need to kill the male cutting unless you want a pollinated grow room.
You can then move the Male plants to a separate space well away from you lady plants and then bloom the males when it suits you!
You may only require one male for the job and it is up to you to choose which male has the desirable traits, you want to use for seeding your ladies!
