Never breed or pollinated, but I did read something about this in one of the Mephisto threads.
Either have a look through their posts or post this question in their thread, Mitch and Tim love to explain how they grow and would be sure to give you an answer.
Don't quote me here, but I think they said - pollinate week 3 of flower, pollinate each bud by hand and only pollinate the lower buds.
You don't want to pollinate the whole plant, because you want quality seeds, so only pollinating a percentage of buds allows the energy of the plant to make good seeds.
Doing it this way you will still get lots of seeds, they also mentioned the best way of drying the seeds and storage.
Like I said, this only what I think I remember them saying, so drop by and ask em.
