...And don't sneeze, breathe too hard or drop the pollen container, lol.
If you must pollinate where she sits, make sure the fan has been off for a few minutes and use slow even movements...as pollen can stay airborn for a loooooong time, which increases chance of your main cola's getting pollinated and stunting the growth of your bud. (the bud focuses on forming the seeds instead of forming more smokable stuff)

About dual-pollinating the lower branches:
If it's an emergency, and you are about to lose a great strain unless you dual-pollinate, give it a try, but, your seeds true genetics will always be in question. I would not pollinate more than one type of pollen per female.
Virtually eliminates the possibility of a screw-up.
Always better safe than sorry.
Rusty Trichome Reviewed by Rusty Trichome on . Pollinating with diffrent pollens I got one sativa and was wandering if I polinated one branch with a diffrent strains pollen could I still pollinate another branch on another part of the plant with the same sativa type plant to get the same strain of seeds as well as a diffrent and the mixed strains pollen wont effect the other pollen or seeds?
