isn’t yield an unchangable genetic trait like mold resistance? I’m no plant scientist but I think that varies plant to plant and strain to strain.
Its weird when you smoke you only want potency but growing you need good yield, good calyx to leaf ratio, nugs that get frosty, strong stalk ability to support said donkey dick nugs.
Best weed plant I personally owned in my garden that was hard to kill and fairly uniform from seed and got me high was Sour Diesel.
Afghan is super easy to grow but for personal weed stash it gets old because its best trait, every plant being homogeneous is its greatest weakness, because if you grow a lot of it and get tolerance fast it loses it’s luster.
So the best way i kow its not cool on the boards but if you dont have space or lots of money, most of the good breeders sell mix packs of their good strains randomly thrown in ten seed pack for discount. It’s random but if you dont care which plant is what strain or mind guessing you can get a crop of keepers with variety, and even the males are true breeding. Getting an afgahn or northern lights keeper from greenhouse or mr nice could be priceless and variety keeps tolerance at bay for me.
