If making just a few seeds, and you fear the risk of pollinating too much, you can dump a little pollen in the palm of your hand and use your finger to apply it. Most pollen goes where you want it with very little hitting other unintended buds. With a brush or a qtip, a little puff of pollen goes drifting…the reason for the tip above about tapping a brush or qtip, which gives direction to the puff of pollen…ie you can aim it if you want. Using a brush or qtip requires airflow to blow pollen away from sites that are to remain seed free, or alternatively as suggested, use a bag to protect these areas while pollinating, or don’t, and afterwards protect your pollinated buds and wash off the rest of the plant.
Lots of seeds= brush or qtip
A few seeds use your finger( unless you have sweaty hands, that is)
I Always use the wind outdoors or a fan indoors( not in a tent) and approach the plant from downwind. There’s no way in hell pollen will go against the wind, So if you pollinate the most downwind portion of the plant, you’ll have no risk of pollinating anything else. Don’t forget to cover your pollinated branch for 24 hrs so the pollen doesn’t fly off somewhere else. When you remove your cover wash off the whole plant, But in particular the buds you pollinated. Don’t forget to bleach your room if you pollinate in there. Pollen can live a month… And will keep knocking up your plant.
A pinky nail sized clump of stigma’s will make between ten and twenty seeds.
Finally, One ballsack full of pollen is enough to pollinate a whole entire crop. Be careful. A little is a lot. If there is very little and you think you will have trouble spreading it to enough bud sites, You can cut your pollen with something like flour or a great tip I learned recently, diatomaceous earth, to stretch out your supply.
An alternative in a very closed in space Is to put some pollen in a baggy and put the baggy over your chosen buds. Shake the baggy once air tight around the stem. Or rub the flowers against the sides of the bag, if that’s where the pollen is stuck. Unless you have a lot of pollen this is a pretty inefficient way.
Thank you upstate! Can always count on you for some good information. Upstate I have a little project going with some durban nights and some excellent cedar smelling bagseed. Hope to have seeds by end of year, I’d love to send some your way uf interested at end of the year.
@nick131740 Happy to help in any way I can. I sure appreciate the offer of seed and very much look forward to your success, but I’m currently drowning in self made hybrids and haven’t grown even one out of way over 100 made lol. I’m all about the landraces for now, and have hundreds to go thru. It does sound like a good mix you have planned. Is that Mexi bagseed? I just made a Durban Oaxaca/ Oaxaca Durban myself, and if your bagseed is mexi, You’ll have made something similar. Tag me when you are successful with pollination😁
@Upstate Thanks for stepping in with the sage wisdom, and the play by play. 
Good lookin out!
