Long story short, some females are slightly hermie prone and some are 100% not. If you use light poisoning it will bring out those hermie traits, making it so that your creating offspring that have a high likelihood of not only carrying that gene in the same amount, but doubling it up. Making further generations more prone to hermaphrodism, unless you light poison and pull 100% of plants that show any male flowers. What your left with after doing that for 3 or 4 generations should be clean, solid female genetics.
If you try to light poison and it doesn’t work, you have a female thats at the very bottom of the chart. Any male flowers and your above that with some intersex genes.
