pollen is no good after a couple of weeks, the fertility is reduced significantly after about a month in perfect conditions. Small glass jar or film container with a couple pieces of dry rice, and throw it in the fridge in the dark, tape the outside, but I wouldnt suggest it
Ive heard of cutting a slit in the side of a plastic cup, with a hole in the bottom, to collect the pollen.
I would just shake the male over the female you want pollinated, away from any potential sensi's, or burst the sacs, and paint brush the bottom half.
Either way, its probably not worth it, unless they're lowryders, or cross pollinating
those sacs will burst anytime, all you need is one with a fan, and seed town
