When Do I Collect Pollen ?

[420tyme]

im wanting to collect pollen of my male plant

so i can isolate it on one of my female branches

so my whole plant wont have seeds , ( just one branch will )

how big do i let the sacs get before i can collect it in my jar

and how will the sacs look ?

im sorry if that is a stupid question

iv never tried to collect pollen before

and i never have let a male plant finish before

i always just trashed them .

thank you for any info you can give me ...
