(CO2) Carbon Dioxide is one of the most important components needed for growing plants. If the plants lack CO2, this will result in slow, hampered growth; this is where the CO2 bags come in; they are a compact and affordable way to get more CO2 in your grow room/environment.

Pierce the bags and hang them (away from heat sources) near a fan that oscillates. Over 2-3 days, the bag will begin to produce CO2; if it hasn't by three days, to help assist activation, insert 1-2ml of water (ensure it is clean) via an existing hole.

Using CO2 bags helps improve your crops' overall yield and health whilst being easy to maintain and set up.
