she has to have pistils, aka hairs showin to pollinate.
flower the male along side the female, if ya can, keep the male back a week. once the male lets loose some sacks, get a brush and brush pollen all over the female hairs, if ya do this in the first weeks of flowerin, then remove the male and waterdown the female to kill remainin pollens.
you will get a bit smaller buds, and all your seed will be at the bottom of your buds, and along the main stem.
or leave the male with the female and make a shit load of seed:D
