I disagree with you all. All my seeds are from out of bud I've brought so they are all from hermie plants. Ive had a few go hermie but I've had a few good ones too and the good ones were very airy buds but very sticky leaf and very potent and that plant came from a seed that had fallen off my first plant that was a disaster of a plant. What grew from that was a nice full female plant.
The gene can die out.
I have hundreds of seeds that I've collected from bud that ive smoked.
At the price of seeds and the risk of bringing them into Australia i would never buy any.
At the end of the day its free bud, to get good stuff you need to spend money on it which i don't have.
