quick question

I have 1 male plant, i know cannabis is pollinated by wind. My question is if i keep that male in my grow room till it flowers and harvest it do i have to be concerned about pollen still being in the grow room for my next crop? If so should i sanitize the walls and everything? Thank you

Pollen is not viable after a few days, if left out in the open air. But cleaning up well after each crop is smart anyway.

Thanks so much
