Fact - using pollen from a hermi plant to pollinate a pure female plant will give rise to nearly all hermi seeds and a few regular seeds with a chance of being either male or female, but with an increased potential of being hermis too.
Hermi pollen contains dominant genes for hermaphroditism and this dominance will be passed on to any seeds produced from this pollen.
They WILL NOT be feminized.
At best they will be regular seeds.
Most likely they will be nearly all hermaphrodite offspring.
Never breed with hermaphrodite pollen, it is the first step in regressing to wild hemp.
Hermi pollen will also have other "undesirable" genes associated with hermaphroditism "piggy back" on the hermi genes, infusing any offspring with further undesirable qualities, on top of being hermaphrodites.
I have been breeding pot strains for 25+ years and have researched this subject thoroughly and stand by my comments - they are scientific , biological and genetic facts, not back yard myths.
I hope this clears up your doubts.
