F1 are known to be rather uniform crossI’ve got an auto feminized strain that I would like to make a regular auto strain. I’ve got an idea to pollinate the female strain with regular pollen from another auto strain creating regular F1 seeds. I would then backcross an F1 male with the P1 female strain to stabilize the original feminized strain. I would take it further down the line bx-ing to the feminized strain to further stabilized the line. P1 x F1 -> P1 x bx1 -> P1 x bx2 -> P1 x bx3 -> etc. Would the F1 gen be right or would I need to bx with an F2 male the resembles the P1 mother? Then after each bx take it to f2 and then bx to P1? Or is it just much more complicated or maybe not more complicated but more in depth and requiring more generations to get where I want?
F2 are known to have plenty pheno variation
You can back cross the F1 or find a pheno with the traits you like in the F2 and back cross that. You can do what you want and it's never wasted time to make seeds cause you can store them many years. No one knows what you will find in there when you are an old grower. Just do it!
