Co2 Supplies

Why use CO₂ in an indoor grow room?

Carbon dioxide is an essential part of photosynthesis. In sealed or well-controlled indoor growing environments, CO₂ supplementation can be used as part of a complete environmental strategy that includes appropriate lighting, temperature, humidity and airflow.

CO₂ enrichment is most effective when paired with healthy plants, sufficient light intensity and good air circulation to distribute carbon dioxide evenly throughout the canopy.
