I’ll generally hang on to them & label as herm-probable. Sometimes I’ll toss them in a ditch and see what happens. Sometimes I’ll sprout a few and see what comes of it. I had someone give me some GG#4 beans and one hermed out pretty bad. Planted 5 of those herm beans. One was a weakling, two had obvious herm issues early in flower, one had a few bananas late, but one stayed true and made some stinky, sticky, rhino-dick buds. I ended up cloning off of that one for years before eventually treating w/ silver & making S2’s for later. It never gave me any issues & some runs took a beating too, mites, thrips, power outages, general neglect, etc. If you’re willing to risk it or be patient weeding through some of them, you might end up with a nice surprise.
