Small Stainless Steel Nat. Gas CO2 Generator 420

The Small Stainless Steel Natural Gas CO2 Generator 420 is a compact, high-efficiency unit perfect for growers who need reliable CO2 enrichment in small spaces. Perfect for tents, small rooms, or low-ceiling setups where precision and safety matter, it’s built from durable stainless steel and fitted with corrosion-resistant components — meaning it’s designed for reliable, long-term indoor use. With features like automatic shut-off, clean-burning operation, and easy integration with environmental controllers, you can maintain consistent CO2 levels without constant oversight. For growers scaling up or that have larger setups, the Natural Gas CO2 Generator Classic delivers higher-output with the same quality features.
