Male room and flower room

[Rhizome]

Dear all,

I have 3 black widow males start producing lot of pollen. A small cabinet with 20w CFL.
But the cabinet is in front of the flower room...
Pollen will go all around.

How do you control the male room to avoid any involuntary pollination of flowering room?

Thanks

I got F5 Filters on the Air Outputs on male tent, and also the Inputs of the girls next to them.
Just like this one, and it worked for me!

Uff...i am not using ventilation in the male room.
Which filter is this( I mean the fabric filter)? I can definitely put on then passive intake in the flower room, correct?
