I already know there’s a lot of ppl on here that’s prob gonna say this is a myth and I won’t boast 100% accurate BUT I did test the theory of 2 seperate runs of 32 plants 1 seed each of all different cultivars and 1st run was 3 males and 2nd run was 3 and a really gnarly intersex la confidential which technically was still a fem. When germinating seeds were already taking a shot in the dark but at least it’s a better shot in my humble opinion and will vouch it’s a good guideline to look for picking through seeds and limited counts
