Does CO2 cover up the weed smell?

My friend went to one of those marijuana seminars (there are quite a few of them in cali) Apparently Stickbud was there, and he was saying that running CO2 will actually mask the weed smell of the grow room. He analogized it to running around with an oxygen mask on.

Stinkbud said that if you don't use CO2 you msut use carbon filters.

For you guys who run CO2, do you know what Stinkbud's talking about? I've never heard of this, though it definitely sounds interesting

Sounds like a miscommunication. CO2 has no deodorizing properties I'm aware of, and even people who run CO2 still use filters.

Same as BlueFish, I think that was a misunderstanding somehow. I know plenty of people who run Co2 with a filter. Myself included. Never heard of Co2 helping with odor.

In no way will it mask the scent.
