@CkNugz I do it in batches of roughly 12 at a time. The ones that pass stress testing in seedling and veg I keep in veg until I have a few good ones to flower. This round I went through 36 gold leaf, 36 white widow, and 36 agent orange. Only 1 gold leaf passed, 2 white widow, and 3 agent orange. I will pheno hunt their progeny as well and do the same stress testing and culling to breed in the vigor and hardiness. After about the 3rd generation so roughly 100 offspring from the line I will start pheno hunting for potency along with the terpenes and hardiness I want. It takes a lot longer because I have a small two tent operation but the end results are just as good as larg scale labs and operations. Just takes more time.
Currently I’m on progeny 2 with white widow, f2 fem with gold leaf, and progeny 1 with agent orange.
This next pollination will bring my white widow to progeny 3, my gold leaf to f3 fem and a few progeny 2 gold leaf fem f1 crosses, and my agent orange to progeny 2. So I’m close. Within the next year I hope to finish these breeding projects I have and have some very hardy stable strains.
