I was around a lot of pot and those growing it in So CA, late 70s, graduating in 77. I honestly can’t recall the term hermies or the equivalent. But then my memory isn’t what it used to be. It wasn’t until now when I started to setup my first grow that I’ve heard it countless times. Some of the old timers I’ve talked to said its in the genetics and if you have good stock, not known to have that happen, you probably couldn’t make it happen.
Looking on the SeedFinder database the quantity of strains is mind blowing. I could probably count all the strains we smoked back then on my fingers and maybe toes. So much competition now to make super weed, wether rec or med.
