What does “CO2” mean?

Also known as carbon dioxide, it's the colorless, high-density gas you most likely learned about in science class. It's used extensively as a solvent in supercritical extraction of hash oil and concentrates because of the low volatility of the gas. CO2 is also added to the air in a cannabis cultivation facility to increase yields.

Example usage for CO2

“If they'd taught us about using CO2 in cannabis extraction, I'd definitely have paid more attention in Chemistry.”
