I wudn stress too much, so long as u purchased from a reputable seedbank..
Do you understand the process for making Fem seeds?
Essentially all Fem Seeds come from Hermi plants, but how this differs from the hermis that we grow is important.
A reputable Seed Bank start with 100's of female plants. Through a series of tests they systematically eliminate the weaker genetics. They hit them with hot/cold temps, hot/cold water feeds, erratic light cycles, diseases & pests etc, until they are left with only a few plants. These are the most resiliant and so are therefore least likely to turn Hermaphrodite.
Then the Seedbamk sets out to force this change through a chemical process. A chemical called Collodial Silver is fed to the plant and it pods up. The pollen has an X Chromosone (normal Male Pollen has a Y Chromosone) the Bud also has an X chromosone. The abscence of the Y Chromosone mean all Offspring have to be XX (Female).
All Hermis r XX, but as I said the difference is that Fem seeds themselves r from good stock and unlikely to turn, but the shit that we get from Bagseed has most likely been broken down genetically, and r unstable and likely to turn on us for the slighest f*ck up.
Sorry 4 the Essay, but it was neccesary to answer your question.
