mating

alright so i got some male pollens stored in a container without the airtight but i hope it woulda work. i am growing outdoors so i dont have the mobility to move my plants. got a white widow male and a northern lights female. and some other strains flowering as well. i am planning to pollinate the bottom part only would it pollinate the other branches as well, or worst my other plants? and if i started brushing it (pollinating it) in what condition should i be doing these? should i prevent having wind and rain? can i wrap a plastic a few hours or a day just so it wont fcked my other plants?

jeeeez wrong category, i was meant to post these at advance marijuana cultivation. but please do give me advice on these

One way I've heard of doing it is putting the pollen in a plastic bag and then inserting the branch into the bag and shaking it. I won't wrap it in plastic and I would watch the weather for rain or excessive wind. Good luck dude tell us how it goes! Heres a link that might help http://www.growing420.com/pollinating.php
