ACV = Apple Cider Vinegar. Just following advice from the link I posted last week re Scarifying. Fingers crossed, really need my native seed (at least) to fire, if at all poss. I would theorize that the best DNA is contained within the hardest seed coats, just as many edible plants, grown 'hard' or even stressed, produce the best eating and keeping qualities. A longshot theory but the other way to look at this, is , maximizing germ via scarifying may be a very simple hack vs all the hours foraging for seed over 3 months? Thanks for the info on seed-swell, that is helpful. Now I wish I left them on the wet napkin to imbibe, haha, more trials to come. Should have several thousand seed from the coming season, have to do better than 5% germ.
