Pollinating LOWRYDER...when&how?

All the contributions regarding pollinating knowledge and know-how will be appreciated a lot.

I am planning to pollinate my lowryder plants, in an attemp to get a harvest of viable seeds.
I have never done this before, so I am not sure what would be the best way to do it. I have some specific questions going through my mind about it:
1. How developped should the female flower be, in order to be able to start producing seeds? I suppose the start of the bud should be there already, when i pollinate...?
2. Since im planning to pollinate just a couple branches, leaving the rest of the plant to produce unpollinated buds, how should I do that? Any suggestions anyone?
I have been thinking of putting pollen into a plastic bag, then putting the plastic bag over a brach. Then I thought I would just shake the branch and the bag to spread the pollen onto the bud and the brach.
Another method I thought of, would be to take a bit of pollen on the tip of my finger (after carefully washing and drying my hands), and then simply touching around the buds...
3. How long should I wait untill I cut the plant after pollination? Of course I want to have the seeds developped enough to be viable, but I would not like to have over riped buds either...

As I said, any contributions on this will be appreciated very much...

Thanks a lot everyone :)

take your male plant away from the girls as soon as possible

when his pods open shake onto pices of paper,put pollan in plastic contaner just the pollen nothing eles.do a few times

it is hard to say when to do the pollenating prolly about 4th week the more pistal the more seed i do it a number of times so i get lots of hairs
the seed will take 5-6 weeks to ripen you will have to let the plant go longer than the other non seed plants
the seed pod will crack and you will be able to see a brown seed inside
you can use a small paint brush or Q-tip to apply pollen ..the hair will turn brown in about 36-48 hours when pollanated.alittle goes a long way

thanks a lot weezer. Very good to know this :)
