In believe u have to grow those seeds out again, take male take female polinate eachother/get seeds/grow out seeds again/take male/take female and polinate/
And this 7 times long you end up with a true own variety.....
If your working with femenized strains its the same only then u treat one girl everytime instead of growing the male ofcourse
With your hermie plants i dont know because its hermie x hermie. I would not waist time u into that.
What u can try is take the pollen from the hermies and freeze them to at one day pollinate a true female and start this breeding proces(praying the hermie genetics will slowly reduce with every breeding cycle.
Hope this helps u a bit!
