Refill CO2 BOOST PAD - CO2 Generating Mat for Healthy Plant Growth
The Refill CO2 BOOST PAD is a practical CO2 generating mat designed to support plant development by releasing carbon dioxide in a simple, natural way. By absorbing a small amount of moisture from the surrounding environment, the mat initiates a reaction that helps generate CO2 for your plants. This makes it an excellent solution for growers looking to improve conditions inside a grow tent, greenhouse, propagator, or glass container.
How the CO2 BOOST PAD Works
This refill cartridge contains natural carbons and acids that react with moisture to produce carbon dioxide. The process is easy and requires no complicated installation. Once activated, the mat steadily releases CO2, helping create a more favorable microclimate for domestic crops and young plants. For best performance, it can be lightly sprayed with water to speed up activation and improve effectiveness.
Why Use a CO2 Generating Mat?
Carbon dioxide plays an important role in plant growth, especially in enclosed growing environments where air circulation may be limited. A CO2 BOOST PAD refill can help support healthier and more vigorous growth by providing an additional source of CO2 when plants need it most. It is particularly useful for indoor growers who want a straightforward and affordable way to enrich their growing space.
Ideal for Grow Tents, Greenhouses, and Propagators
The CO2 BOOST PAD is suitable for a variety of growing setups. In a grow tent up to 150x150x250 cm, it is recommended to hang 1–2 mats above the highest slat for optimal results. In smaller spaces such as a greenhouse or propagator up to 60x40x30 cm, a cut piece of the mat can be used to deliver CO2 in a compact environment. This versatility makes it a valuable addition to many indoor cultivation systems.
Long-Lasting CO2 Support for Plants
One of the key advantages of this CO2 generating mat is its duration of work. In a grow tent, the mat can produce carbon dioxide for up to 4 weeks, offering a long-lasting solution for plant support. In smaller propagation environments, a single cut piece can work for approximately 1 week. After the active period ends, simply remove the used mat or piece and replace it with a new one.
Easy to Use and Simple to Maintain
The Refill CO2 BOOST PAD is designed for convenience. To activate it faster, spray the mat daily with about 50 ml of water. This helps stimulate the reaction and ensures the CO2 release begins efficiently. The product does not require any special tools or complicated setup, making it a user-friendly choice for both beginner and experienced growers.
Perfect for Young Plants and Domestic Crops
This CO2 mat is also a great option for young plants stored in glass and for domestic crops grown in controlled conditions. By adding CO2 to the environment, it helps create better conditions for plant development during sensitive growth stages. Whether you are nurturing seedlings, propagating cuttings, or supporting plants in a tent, this refill mat can help you maintain a more balanced growing atmosphere.

How to Use the CO2 BOOST PAD for Best Results
For the best results, place the mat according to the size of your growing environment. In larger setups, hang the mat above the canopy level so that carbon dioxide can disperse effectively around the plants. In smaller spaces, use a cut section of the mat, moisten it gently, roll it into a compact shape, and place it inside the growing container. This allows the CO2 to be released directly where it is needed most.
Important Notes Before Use
The Refill CO2 BOOST PAD is sold as a spare cartridge, and no hanger is included. Make sure to choose the correct placement for your setup so the mat can work efficiently. Once the active period is over, replace the used mat with a new refill to maintain a consistent CO2 supply for your plants.
