Nice man, if i just got some seeds in lower buds i will be quite happy actually! Thanks for the info!!You will get a single seed when ever an individual pollen "spore" comes in contact with a pistil and fertilizes that pistil. It's not like a virus or infection and spreads to other areas of the plant. Same as humans....1 sperm fertilizes 1 egg. Your one pollen sack with fan going....probably 50 seeds.....no I'm bullshitting. I had a bagseed hermie last time and SOB screwed my shit up.....top of buds were seedless. Lower section had seeds because of the same thing you have....I missed a lower pollen pod and poof, seeds. Nice grow!
