Sorry. Been crazy over here. There is a couple of things you are going to have to weigh in on.
1.) Are these seeds ALL displaying this hermie quality? If they are...AND you dont have any more seeds left over to restart another grow...i would finish off the grow and see what you get. .....but there is a hazard associated with doing so. If you allow these hermies to grow and pollinate themselves, there will be residual pollen left in your grow box when you grow next time. You will have to mist the entire grow box before running a second time, otherwise the pollen can fall and pollinate your next round of growing. Easily fixed with a squirt bottle and a bit of time. By doing this you will either get a bit of bud and a bunch of seeds OR just a ton of seeds. The thing is about that "quality" of hermie...or "severity"...is that its not even putting out "bananas" that pollinate itself. It is putting out full blown pollen sacs. I have not run a plant that hermies tgat bad, all the way to completion. So i have no real clue how severe the "hermie" trait will be. As i said. IF you have no more seeds i would run it to finish and see what i get.
2.) If you have more seeds to start over with, i would do that.
The thing is, is when we find a few seeds in our bags, we have no clue how bad the "hermie" quality is. Or how strong it is. With your plants forming full pollen sacs, i am concerned with how seedy the bud will be. It would be smokable after you sift out the seeds. And perhaps the resulting seeds it produces WONT display such a strong hermie trait. Thats a possibility. Allowing you to try and grow that strain again.
I am a fan of the hermie. Call me crazy....(who said that?)...but when i have a pretty boss strain that kicks out genetic replicas of itself, i am pretty stoked! But my stuff doesn't produce pollen sacs. Matter of fact i can't even really see the seeds it makea unless i look REAL close.
So if you have more seeds, i would try another run. If these seeds are ALL you have...i would pick off the sacs amd try and run them to flower. Picking off the sacs is a tedious task and most if not all would throw in the towel on such a venture.
