Aluminum CO2 Tank

Aluminum CO2 Tank – 20lb & 50lb Options (New or Used)
Lightweight. Rust-Free. Built to Last.

Whether you're enriching your grow room or greenhouse with supplemental CO₂ or setting up a commercial setup, these heavy-duty aluminum CO₂ tanks offer a lightweight, corrosion-resistant solution that’s ideal for long-term use. Available in 20lb and 50lb sizes, each tank is crafted from high-strength aluminum, making them nearly half the weight of steel tanks and significantly more rust-resistant.

Tanks are available new or used, allowing growers to choose a solution that fits their budget without compromising on functionality. All tanks meet DOT 3AL and TC 3ALM manufacturing standards and are inspected and tested by certified independent agencies to ensure safety and reliability.

Why Add CO₂ to Your Grow Room?

Supplementing carbon dioxide (CO₂) in your grow room can significantly increase plant growth, vigor, and yields—especially in enclosed or high-light environments. Plants use CO₂ during photosynthesis to convert light into energy. When CO₂ levels are elevated from the natural atmospheric level (around 400 ppm) to an optimal range of 1,000–1,500 ppm, plants can photosynthesize more efficiently. This leads to faster growth, larger leaves, more robust flowering, and increased harvests. CO₂ enrichment is particularly effective when paired with strong lighting and ideal temperature and humidity conditions. For indoor growers aiming to maximize their space and speed up their grow cycles, adding CO₂ is one of the most impactful upgrades you can make.
