How to purposefully get seeds?

[maspino1]

if you want seeds, take pollen from the male plant, save it, grow a female plant, use a brush
to carry the pollen and brush it onto the female's pistils et voila, you got semillas

but i also heard you can just brush it onto a few branches and get seeds where you brushed
it and then you can harvest the non-pollinated buds and smoke up
