Based on your experience, in order to get F2 SRT, should I breed F1 female with a father or better with F1 brother?I said “nearly all” f1 look like trash. It’s a lottery to find one worth a damn. To can talk all you want, actions speak louder than words and I back up what I talk. I have grown thousands and and thousands of F1 hybrids out to 9 months so I have a pretty damn good understanding of what you will get. I don’t do this early culling bullshit like everyone claims. F2s, yes will be all over the place if inbred. That’s what happens when you start paring up recessive alleles.
