how many times do male flowers open to release pollen

hi guys, i started a breeding project to preserve a really dank ass clone of la confidential i got using some cs and to pollinate another dank ass plant i grew from seed with the la con.
the only problem is i noticed some bananas on this piece of fucking shit dna genetics pure afghan plant which isnt part of the project. they were full of pollen when i plucked them off and grinded them to confirm. what i want to know is, once the flowers open, do they stay open and release pollen from then on out or do they close and open daily. for the most part i saw nothing but closed ones so im hoping none opened and ruined everything. also praying that none opened prior. thanks a ton in advance.

once they open, that's it, they spew what pollen they have and dry up
at least every male i've seen

thank you!

spray with water to kill the pollen dude before dicking about with any male

They will drop pollen for weeks.
