Tanks & Regulators

CO2 tanks and regulators take the guesswork out of adding CO2 to your indoor garden. Grow room CO2 can be used to boost the growing potential of indoor gardens. While ambient CO2 levels are generally in the 350-400ppm range, many indoor plants will benefit from increased CO2 concentration. Grow room CO2 is created from a variety of sources. Commercial growers and hardcore hobbyists prefer to supplement directly with CO2 from 20lb containers. Our aluminum tanks are labeled with the HTG Supply logo, and shipped empty to due to shipping regulations.
