Breeding Autos

I picked up some non-fem auto seeds this year with hopes to play around making some seeds for personal use. I have my first male and def seems way ahead of the females, which from what I've found is good thing.
What should I be watching for on the sacs to know when to chop and collect? With autos when is the best time to dust the females? Thanks all!

Got some reccomeandations to transplant indoors, main reason at moment as were getting hammered in rain again. Better pics of balls attached. What am I watching for for best harvest time of pollen and any reccomeandations on method and storing??

Lot of people catch pollen in a bag and just store it in that bag or scrape it up and put it in a vial. I would assume a cool dry place for storage but search around im sure the topic is covered. Whenever sacks open, start collecting.
