How longer after showing sex will male plants infect females

I took clippings from a few plants to put under 12/12 to sex them. How long after plants show male characteristics until they would pollinate the females. I am going away for a week and am worried that they will show sex while I am away and unable to cull them. Thanks

you should be fine for a week.

I'd say at least 2-3 weeks before they'll drop pollen
