Co2 Gas Bottles for Hydroponics and Plant Growth

Hydroponic growers use CO₂ to elevate plant metabolism, leading to stronger yields and healthier canopy development. Our cylinders provide consistent output suitable for automated regulators, solenoids and grow room controllers.

For general CO₂ applications, explore our CO₂ Uses page.

Select a cylinder size based on the volume of your grow space. Small tents often use compact cylinders, while large indoor grows benefit from higher-capacity bottles for longer intervals between refills.
