not true at all. spraying a plant with a chemical such as c/s does absolutely nothing to the dna of the plant, it simply inhibits the plant from producing ethylene, the hormone that tells the plant to grow female, pistillate flowers, and instead, the plant grows male, stamenate flowers in their place..
so long as the mother plant is stable, it's offspring will also be stable.. again, the spraying the plant with any chemical doesn't cause any hermie trait that wasn't already present in the plant to begin with to happen..
if the mother was stable, you'll be stable, non hermie prone seeds, this is true whether you create feminzed seeds from the mother, or normal, male / female seeds from the mother.. if it's not stable, and there's a hermie gene present, than obviously, the offspring will have the same chance of expressing those traits as the mother has, again, this is true no matter what kind of seeds you were to make from the mother..
so long as the mother is stable, there is no hermie gene present, and the only reason she grew balls in the first place was because it was sprayed with a chemical, such as collodial silver, which told the plant to stop producing the hormone ethylene, which is the reason the plant grows female flowers.. if you never sprayed the flower with a chemical such as c/s, you'd never have balls on the plant, meaning that there's no hermie gene present in the plants genetics, so there's no way to pass on a trait that's not there to begin with..
