Co2 Enrichment

CO2 enrichment refers to elevated atmospheric carbon dioxide levels during cultivation, not an inherent aroma or terpene profile in cannabis. This environmental practice affects how plants metabolize and express volatile compounds, potentially influencing secondary metabolite production. Breeders and cultivators monitor CO2 enrichment as a growing condition variable that can impact terpene expression and plant vigor during vegetative and flowering phases. Higher CO2 concentrations (typically 1000-1500 ppm versus ambient ~400 ppm) are commonly associated with increased photosynthetic rates, which may correlate with changes in aromatic compound accumulation. Understanding CO2's role in plant physiology helps breeders select genetics responsive to controlled environment cultivation. This is a cultivation technique, not a strain characteristic or flavor descriptor.

Breeders working with controlled-environment genetics often select for plants that efficiently utilize elevated CO2, as this trait influences yield potential and metabolite production in optimized growing systems. Lineage records from commercial breeding programs frequently note CO2 responsiveness as a cultivation consideration when developing cultivars for indoor or greenhouse production.
