CO2----Do I need it in my grow room?

Some devices for measuring flow from bottles, were basically about watching bubbles rise through water. I'm on the loop on it all tbh, but seeing the size of them gauges, and how my turbo brews empty airlocks of there water, I have to say brewing can produce meaningful amounts. It's not a cheap option or one easy to regulate though.

What we could really use here, is a brewer with co2 meter to chime in. Though I won't brew without piping my airlocks outside. I don't want to grow yeast in my hydro. Which hasn't been an isolated case. So I'm unsure why we don't hear more about it.
