Your still missing the point, S1 to S1 makes no difference, Its the tendencies entrapped and locked in the plant that matters. Not sure what your not grasping about that. A late stage hermie plant is a HERMIE plant. wether it does from low light levels , interrupted light, bad nutrients, Its a stress response that requires the plant to reproduce without a male. Its a genetic blessing for plants that arent meant to be smoked but survive. We chemically block the etheylene that makes a female a female. She grows male flowers. No matter or not if she
was born to do so she is going to grow male sacks because she has to. Its a common misconception that S1s are gonna hermie no matter what because its a self pollination. That is 100 percent bullshit. If you take a plant that absolutely will NOT toss a nut at any stage and use its own pollen to make seeds those seeds are as stable as being hit with a male. WHY? because the plant NEVER had hermie tendencies in it to begin with.
Late stage fems IMO is a lazy ass way to make fems and people that cant reverse a female correctly can get away with it. All they are doing is inserting hermie genetics into the gene pool.
Why do you think females like GG4 and other bag seed femz are hermie prone? because they came from a plant that hermied. Its a risk some people are willing to take to find a fire ass keeper. But people still use stable males to make F1s of those moms. Yes there are plenty of offspring that wont herm. But there is still the risk when using those genetics. Bottom line is hermie tendency is passed on just like other traits. If it wasnt than we may as well just toss all our seeds into the same cup because were all looking for something particular from a particular cross. Unfornutely hermie genes go along for the ride when either of the parents have it.
