I watch them and when they look plump I pick one and disperse its contents directly on white pistils. If nothing comes out, I wait longer. After a week or so of picking them, they will all start to open and pour out on their own. At that point I just let nature take its course and my fans push the pollen around. For a more detailed explanation, check out post #1421 on this thread, its on page 95. It shows the instructions I followed exactly for my first two successful pollen rounds.
