@bobo66, good results! I don’t think there’s a huge difference between the most popular stocks, as genetics and technology is pretty similar. Proper selection from scratch would take decades. They produce at least few strains every year. That means they are keeping the wave of strong genomes by constant crossing the most good-looking phenos. All base strains were developed long time ago. Anyways, RQS is one of my favourites.
