Yep.
Until you realize you have only these hybrids.
You want to try the old ones but cant.
A grower i used to be friends with spent way too much time explaining this to me. I didn’t really get it either but I guess its rare for these hybrids to be “better”
Takes like 1000’s of generations to get something interesting. Instead you just get sickly plants or super susceptible to parasites and stuff.
