Hiya Patroller,
I am new here, however the seed instiute in St Petersburg had a lot of problems with cross polination last year. You can have no air flow between the rooms without at least a 10 micron filtration system.
Your best bet is to totally separate them.
What are you doing, are you a breeder?
I don't have the chance to breed much anymore and I really miss it.
