when to harvest the males sack for pollen?

So i'm growing a male for the pollen that i will spread on a female for the seeds, i read the help thread and it showed me how but never showed me what tyhe sacks will look like when they are ready

so i guess my question is this:

How will i know when the male pollen sacks are mature enough to cut to use thier pollen?

hope that was clear, here is a pic of were the male is at now

i start ricking them when they look like little bananas. and some of em are starting to open up. on a male this can be anywhere from 6 to 8 weeks into flower.

i wait till the balls open you see little bananna things then i grab a cup and shke them over the cup to see if their letting loose ....then i cut all the open sacks off in the cup ...i repeat the proccess till have lots of polllen.You can tell when they open ....just give a light tap to it an you will see the pollen fly out.....I hope you have in a seperate room.Once my male is showing sex i just put in a seperate room and it runs on daylight until i have enough pollen....

well put jasper lol
