F1- variation is limited to specific phenos based on parents
---Hybrid vigor would be most visible in this generation
F2- more variation in phenos, I'd personally only grow F2s to find one perfect mother to take clones from, or for inbreeding purposes, if at all; less vigor than F1s usually.
[F n- I believe this is the origin of some very localized strains. Began with bagseeds for all we know, but was inbred based on performance of F n offspring in very circumscribed conditions, using only acceptable F offspring for breeding.] This was the origin of my personal stock, and I never did any backcrosses, then I began outcrossing to Afghan males.
BX- This is the generation where you start stabilizing traits you like by going back to your original stock and testing for homozygous traits, and isolating which offspring of your F generations has them.
