In outdoor crops, especially those where you plan to use a small number of large plants, sexing the plants it might be a great idea in terms of saving space and resources. A very good option, and totally viable due to the prolonged growth period that cannabis enjoys when it is germinated in spring, is to take a cutting from each of the plants (it can be two or three to be sure), root them indoors and when they have rooted, leave them with a photoperiod of 12 hours of light and 12 of darkness, this will make them start to flower and reveal their sex, which will be the same as that of the original mother plant that we have in the outdoor garden.
If you germinated in September or early October you can start taking clones in January, put them indoors with a 12/12 photoperiod so that when they flower they show the sex, the clones coming from a plant with a certain number of weeks or months old do not need to be put at 18/6 (vegetative period) for them to continue growing because in 12/12 they adapt and grow well to flower.
I strongly suggest you not to put the mother plants for a few weeks in 12/12 hours of darkness and then back to 18/6 hours of darkness to determine the sex
Forcing revegetation will cause significant hormonal changes inside the plant and is an easy way to induce stress in the plants, which can lead to the possible appearance of hermaphroditic plants.
