I believe everything except odor free. Got a link to evidence?

  No, I have not (only anecdotal evidence) but getting odor free is a matter of getting an active carbon filter (big enough, 3-10 kg) and a good ventilation system (required for cooling anyway). This ensures that the grow space is slightly underpressurized and all the exhaust air is odorless. Without these measures, it will stink. It needs a bit of investment and some time to get the build right, but it can be done.
