i put pollen on the top of 3 buds on a different branch, now the way i did this was to get the pollen of the male and tap it onto black shiny paper, i then blew off any pollen that was loose and would get air born, i then rubbed this paper over the 3 bud sites to put pollen on and it worked great, but it did not just give me seeds at the top of each branch, the whole bud i put pollen on it making seeds not just the top of the bud, you wouldnt even see it if it was air born, the slightest movement of air will make it become air born, i took my plants out the ir grow room and put pollen on well away from the other plants, then left it an hour then sprayed with water to make any loose pollen not viable, im just waiting for the seeds to be ready, ill be harvesting the plant tonight and leaving the buds with seeds in on the plant so i know the seeds will be ready
