Not to cause a stir, but I am not convinced that the odd seed you find in your finished buds are caused from pollination. I have a small cabinet in my basement. I have never smoked with anyone, I don't show other people my grows, I have never been to anyone else's grows etc. Literally 0 chance of pollination & I have found seeds in my buds. Just the odd one, but they're there. I have grown those seeds & have had nothing but females from them plus the smoke I found the seeds in was certainly above average.
I did have a hermi last grow which I tossed out, but that was before it had a chance to do any damage. This was due to a lighting issue.
I may experiment on my own & actually purposely make a plant hermi & try the seeds from them to see what I get. Everyone says they will probably hermie but I want to see from myself. that's the best kind of science
Will keep you informed when I work it out.
