this is one of my trademark rambles. Nothing to add that hasnt been said.
as for gg4 going herman on us, thats only because there was only one original gg4 and it was an s1 clone only cut propagated through commercial growers first as far as i know. A clone wasnt kept of the plant in the original hunts because it was a bit of a lanky, creeper-esque dep structure wise. After the cuts they lucked out and found a single s1 in the plant, and as luck would have it, it was even danker then the missed original pheno, or something. This was what i was told from a commercial breeder friend back in KC.
Theres only limited ways to get something like a one-off s into a stable fem seed consistent with the original pheno, and it involves a bit of repetition and unavoidable recessive trait stacking lol.
That original clone only gg4, there has probably been metric tons of that stuff grown without a single banana or male flower seen, nor any genetic drift. That clone was a damn near miracle as far as that goes, and plenty are still growing that original clone too.
im not trying to go "whoo ha! youre wrong!" or anything i swear, i just played with that clone for a while, brought it back from work in KC. It was the beginning of my best outdoor lineage. I grew that clone for like 4 years and didnt see a single herm.
Shit i even went through that whole "new girlfriend" phase where all your flowering plants basically whither into a state of partial life, partial zombification from neglect, it still never hermied.
Really i just think its funny, that the single most hermie-resistant clone ive ever grown, resulted in some of the most hermie-prone stable fem seed stocks around 
Could quite literally clone a clone a clone over and over again too, and yields and flower structure would stay the same. Lanky and weird lmao. that first gg4 commercial cut, was almost a miracle plant imho. If you made an s2 with it, ever single seed would hermie though.
That might be another strain g13 or someone claims to have bred years before it ever even showed up on any forum posts or the wayback machine too though too, who knows lol. Shit, did i say that? M'bad. i blame the high life.
