Idk what would cause the same stress over multiple grows in multiple houses in multiple tents. With other strains that don’t herm.
From what I understand it is a stress response but it’s more genetic. Like breathing on a plant lol
But if you wanna be cheap like me running f1s and all your friends new crosses and shit it’s just something you gotta keep an eye on I guess haha
If it was a feminized seed that's something you have to keep your eye on in general with feminized seed no matter where they come from or how they're made unless you know for sure that whoever made the seeds is intentionally avoiding stacking recessive genes on top of each other through inbreeding
Feminized seed can only come from hermaphrodite pollen. That's how theyre made (over generalized a bit, but very true)
Your friend's non inbred crosses are going to be more Hermie resistant even if feminized than anything that crossed and fully stabilized from a seed bank. Fact. Doesn't mean you won't see them though especially if they're feminized crosses. And especially if they haven't been there with that plant through the development of its lineage to know what kind of recessive traits are within it
Some of those crosses from your friends are probably going to be from plants that just happened to Hermie next to each other and we're both feminized seed. Hermes only come from genetics but it is absolutely a stress response yes. But it is a recessive thing. Both parents have to have it whether it's expressed or not for it to express in The offspring.
Too much recessive gene stacking in a feminized lineage's genealogy and you'll likely end up with plants that have a Hermie stress response if you so much as look at them wrong or even barely overfeed them or get em too dry. Even if they have no visual stress indicators aside from Hermie
The thing is, that the willingness of some lineages to go Hermie even without any major stress involved, that's not actually the fault of the grower but the fault of the breeder. And I say this as someone who tinkers with breeding pretty often and has for a long time.
I can say with pretty strong certainty that the peace blaster fem f2 will likely have more easily hermade plants in it than the other fem crosses I sent simply because of the inbreeding it takes to stabilize plants. But I also won't be taking any feminized generations further than that f2, I'll be taking it back to the reg side of things to run successive generations for stability before I ever make any more fem crosses with it. So if I make a fem cross between two identical females at the end of that I'm very unlikely to see more than a one in four to 1 in 10 Hermie rate because the recessive trait will only be stacked on itself once at that generation even though it's fully stabilized
I'd say on the queen being the banjo blaster you'll have a 1 in 10 easy heard me right, it's probably more like one in five on the piece blaster f2 though. And that's entirely because of the breeding it takes to make those seeds.
The reality is a lot of breeders don't even work with anything but females these days and treat the her ie thing as just something that's going to happen, a given, and then blame the growers when they're annoyed about it. That whole minor light leak causing nasty Hermie thing that was all over the early mid-2000s was literally breeder disinformation that was intentionally designed to get the people who bought their seeds to blame themselves for the shoddy breeding
