Male auto plants

Hey guys just wondering if I plan to breed my own auto seeds paintbrush method. After separating the males from my cab do I need to worry about smell they'd all be in solo cups as I'm only doing a seed run with a few of the girls. Do I need to worry about the males stinking to bad I'd only keep three or four? I have only one neighbor but its a townhouse with an attached wall just field on the other side of me. We own the property so no worry of landlord coming by. I gues what I'm asking is do I have to build another cab and carbon scrubber? I've grown before. Never autos but I've never kepty males for breeding or always had fem seeds so...

The smell shouldnt be too strong. And one mature male plant would be enough pollen for about 30 females.

I've got four strains I want to reproduce though. Onyx, shark bite,blue hymalayan diesel, Russian rocket. Plan on germing three of each in hope not all female or male. So four essential. Also got some berry ryder and purple cheese fems in bigger pots is the plan for some smoke.

Probably wont start for 2 months or so till the inlaws are done with their viset to town but got the itch again

If there is a chance of anyone suspecting that you might be growing. I would mitigate any smell issues before they arise. (better to play it safe than take any chances).
as for your breeding. You'll only be able to cross like that until F3-F4. Referencing "Marijuana Botany" the Breeding Chapter.

Will a few small males really smell that much though? They drop pollen just a few days after showing sex then I'd kill them. Also I plan on just doing on seed run to get 30 or 40 of each strain then ill start to cross breed to avoid any issues down the road. Is that accurate? Thanks

First off, where do you plan to get these "auto" males?
