If your got more kitchen sink run that shit. You just got bad luck on that one, I just finished a run from seed. I started with 54 plants of various strains after pulling some late showing males I was down to 48 plants. I had 4 plants Herm on me, I got 3 of them early but one snuck by til I saw a pollen sack on the floor. Was in middle of a row so hard to see the middle of the plant where I found the rest of them.
You might be alright anyways as I just finished trimming the plants around that one and only a few non viable seeds were found and they had a good 35 days to work on making seeds after I found and removed that plant.
I had a pack of 6 kitchen sink in the room and no herms at all, smells are amazing. Plants are taller than most other strains I ran this run, most of them look to be different phenos but have some similarities in growth as far as size. This was a hard ass run for me especially with so many different seeds and a new room. I was not easy on these plants and they took it in stride and still produced beautiful flowers. I haven't trimmed them up yet and got a while before can smoke but there are definitely a few contenders to be keepers in the kitchen sink and I'm pretty picky.
EDIT: sorry for some reason this post was up, I'm now not sure how old it was when I replied to it but I don't even see it anymore.
