Krogith & lip both of you please STOP. Your actions are rude to Florida Mon Hijacking a thread is not cool.

FM to answer the question.

The clones are rooted under 24/0 to push them. You are not going to finish them so don't worry about stress at this point. It will take about 10 days for them to root then switch them right to 12/12 and you will know the sex in about another 7-10 days.

The original plants keep growing and you can clone in a closet or cabinet so room is not an issue for cloning for sex.

Your original plant should be around 35-45 days old when you know the sex.

Sexing by clone is the most efficient way to determine the sex from seed. Very little to no stress on the plant. When you sex the whole plant then reveg you are sending mixed signals to the plant and that is not good.

You can get hermies from stressing the plant, not saying it will but it sure can. As if the seed was from a hermie mother then the chance of that seed being hermie is increased. That little stress of sexing the whole plant could be enough to trigger the hermie trait in that plant.
