how long can i sex them for, how long can the males stay in?

i was just wondering when they start to show pistils and ball sacks, how long can I leave the ball sack males in with the females? seriously though, please.

Week after flip. Sometimes sooner.
As soon as I see balls...they be gone.
I personally don't have use for Males or Hermies

If you want seedless bud in the females, you have to get rid of the males immediately. If you accidentally contaminate your grow area with pollen, it might mean seeding crops now and in the future. That pollen finds ways of hanging around if it accidentally escapes a sac whether you know it has or not.
