In my experience, seeds formed from hermie flowers tend to produce plants that also grow hermie flowers. I once ruined some excellent White Widow genetics when they received pollen from a Master Kush that went hermie. I used the seeds and got WW with pollen sacs early on. And they weren't the easy to spot kind that form near the top of the bud. Those sacs formed up under the bud and hidden by bud leaves. I thought I could save the crop by searching out the sacs and plucking them, but it didn't work. That was 10 years ago and since then I'm a lot more careful about it. When I make seeds I only use those that are on the branch I pollinated. All others are sicarded. I know I'm usually tossing good seed, but that experience left an impression on me. Right now I've got a branch ona Blubonic that I pollinted. On an adjacent branch are a number of seeds that are obviously just spill over pollen from that branch, but they'll be shit canned. Call it over caution, but if you ever ruin a crop by having unwanted seeds all over the place you might become over cautious too.
