I have done some extensive breeding. My process would be to grow out regular seeds and select males that displayed admirable traits such a stalk thickness and node spacing.
Once the males were found I would let them grow to near maturity where they are almost dropping pollen. I would chop the top(s) and place in a shot glass of water and set the shot glass on a picture frame; all under a small CFL to keep them alive.
The male top still continues on as if nothing has happened to it. Once the top(s) drop their pollen I would scrape it up with a razor blade and place in a small paper bindle folded up origami like to keep it sealed.
I would allow the pollen in the paper bindle to rest in ambient house temperature to allow excess moisture to be removed and wicked away. I would then place in a pill bottle with desiccant packets to continue the drying.
Then I would place in the freezer. I have saved and used viable pollen in this manner that was 8 months old at least. It doesn't last forever, and I don't know where the cut off point is.
Once I had a female that was displaying admirable traits as mentioned above I would send it in to flower. 2 weeks in to flower I pull a single bindle out and place in the fridge.
Slow acclimation to ambient temps are crucial. If the pollen bindle warms up too quickly condensation can form on the inside of the bindle rendering the pollen useless.
Then I would use a tiny plastic container for beads with a lid to place the pollen in. These are found at the local hobby store. Then I would use my favorite paint brush and dust the particular bud I wanted to pollinate.
Yeah, it isn't the most careful method as far as the pollination goes. Some rogue pollen will inevitably drift and get on other buds. It never totally ruined a plant and once the pistils are seem to curl back brown, pollination was a success.
Let the buds go for another 4-6 weeks and the seeds are ready for harvest; presto. You just became a pollen chucker.
