I have a 100 Dynasty seeds That I need advice/help sexing!

I am using Gavita Pro DE Fixtures, 3 gal grow bags and soil medium, and house and garden full nutrient line. I started the seeds 3/15 and flipped the lights on 4/20 they are about 1 1/2 ft to 2 ft tall. Some are showing preflowers and possibly male traits. I will try to post a few pics later My questions are:
1 How long on average after flipping do they show sex.
2 If I see a pollen sac, should I kill it now or wait for a few more (sacs) to make sure.
3 When will the start pollinating. As in how soon after seeing the first sac.
4 Can I Use them for anything
5 how will I know if it went hermi?

Thanks for all the help in advance!

1) from a few days to a few weeks, depends on the strain but often 5 to 7 days
2) wait until you are 100% sure
3) typically 3 to 5 days before the male will spew pollen
4) burn or bury them
5) you will see female flowers and male pods both on the same plant

Thanks man ! But that 3-5 days makes me nervous. I don't want em pollinating.

You'll definitely know the sex 2 weeks after you've induced flower. If you see males just take them out, unless breeding. Any balls you see take the plant out. Questions 3,4, and 5 mean nothing to me. Take out the males. Lol

The best way I have been told, is to take a clone of each plant during veg. As soon as they root, start to flower the clones. Throw away the plants that have male clones.

thanks guys I got it worked out girls are good healthy and big
