Need them!

You need a male. Unless you want to make fem seeds. I like to paint the pollen on with a little brush u get more and can only do one branch it you want. Just collect the pollen in something like a film canister and use a small paintbrush to paint it on the white pistils. Takes about 6 weeks to produce viable seeds so you need to do it like week 2 on an 8 week strain. Use water to stop the spreading of pollen to other parts of the plant you don't want seeded.
