ok, im sorta a newb at growing and i have a question on how to keep from the plant pollenating its self so i can get more seeds. Ive heard some techniques like put a fan near your plant and stuff, but i was just wondering if there were any other ways to keep this from happening.
Dude, you pose a confusing qustion, or you give such little info.
If you are growing several plants, and dont care about your buds, you can just allow the male and female plants to grow together naturally. They will do there thing, and you'll have a lifetime supply of seeds.
However, most of us, do not want to put the effort into a grow, to have it ruined by seeds. Once seeds are started, a female plant stops putting it's energy into the buds, and focus's on the seeds instead.
Alot of growers who want seeds, do want is called selective pollenation.
Look at my signature, you'll find an indepth thread on how to perform that.
After you've collected your pollen, you can use a q-tip or a model paintbrush to literally paint the lower buds with pollen.
This way, you'll still have some nice ass buds to smoke and plenty of seeds too.
Peace.
