Carbon dioxide is a fundamental building block for plant life. Without an adequate supply of CO2, your plants' growth will stagnate. The CO2Bag® ensures your garden never falls short, providing a constant stream of essential carbon dioxide.
The CO2Bag® is a compact and powerful solution designed to optimize your growing environment. It is the most efficient and cost-effective CO2 generator on the market today.
Just as we need oxygen, plants need CO2 to thrive. In indoor gardens, CO2 deficiency is often the primary factor limiting performance. The CO2Bag® boosts growth rates, accelerates ripening, and maximizes your overall crop yield.
With enriched CO2 levels, your plants can thrive in temperatures 3–5 °C (5–9 °F) higher than usual. Note: This increased metabolism requires more water, nutrients, and light. Adjust your feeding schedule to fully unlock the potential of the CO2Bag®.

Make a few holes through the top of the CO2Bag®. When contacting air the powder inside starts to release carbon dioxide for your plants.

Hang the CO2Bag® in a dry place higher than plants but not directly above them. Carbon dioxide is heavier than air and it will slowly flows down.

Enjoy the power of carbon dioxide: improved taste, bigger crops and a beatiful color.
More is more.

Recommended temperature is +25 ºC (77 ºF) ->
In a dry place higher than plants but not directly above them. If you have a ventilation, hang the CO2Bag® on opposite corner of a green room.
Yes, but efficiency is key. Since CO2 is heavier than air, hang the bag above the plants but away from the exhaust fan. If your ventilation is very powerful, the CO2 may be sucked out before plants can absorb it. In such cases, consider using a timer for your fans or adding an extra bag to compensate.
Under normal conditions, one bag produces CO2 for approximately 1 to 4 months. The duration depends on the ventilation of the room and the number of holes made in the bag.
Carbon dioxide is heavier than air so it slowly flows down.
