If you want to keep them in the same tent/room as your females, you need to isolate them completely.
If you put them in their own tent, then you need to make sure that tent has negative pressure (pulling air out faster than it goes in) and its own carbon scrubber of course. Whenever you open the door to said tent, you should do it as far away from your females as possible. You can help avoiding pollen from escaping by spraying water the moment you unzip the door and keep spraying.
This is a male isolation chamber DIY manual for containing males and flowering them out in the same room as the females.
Probably the best bet in your situation.
I cannot comment on outdoor in San Diego at this time of year etc. but males can definitely be flowered out on your windowsill for example as well. They don't need a terrible amount of light.
Whatever you do, just make sure you do it far away from your females as pollen does carry over quite a bit and spreads like hell. Also change your clothes before you go back into the female flowering area after harvesting pollen...
