You know, after all these decades of thousands of breeders breeding thousands of strains and growers growing millions of packs... you would think it would be no problem at all to buy some seeds that produce buds that burn with a loud hazy musky, leathery incense... yet far from being easy, it’s practically impossible! Wtf?!
It is complicated math. Take the number of people who want an 8 week strain and count how many generations of selection they have been working on. Then take the number of people who want to pheno hunt and select plants from 20 week or more type plants. Just my guess but I would say the more conveinient strains have been selected several 1000 more times.
