The CO2 Boost Cube Refill is the natural and effective alternative to maintain a constant supply of carbon dioxide in Indoor cultivation. Easy to install and risk-free, this refill ensures an optimal environment to maximize plant development.

The CO2 Boost Cube Refill is a replacement container designed for the CO2 enrichment system in professional crops. It is changed quickly and allows for a continuous supply of carbon dioxide in grow tents and sealed rooms.
Thanks to its natural formulation, it generates CO2 without the need for heavy cylinders, without heat, humidity, or risk of combustion. Its estimated duration is 60 to 90 days depending on use, which guarantees a prolonged cycle of CO2 release that accelerates and increases the growth of cannabis plants.
It is an essential accessory for those seeking consistent results in spaces of up to 6 m². Once opened, the contents must be used in their entirety, as it cannot be saved for later.
The CO2 Boost Cube Refill is designed to be easily integrated into indoor growing systems. This cube releases natural CO2 through a small compressor connected to the container, which distributes the gas directly over the plants.
Made with ingredients from compost, it is an organic solution that maintains an enriched atmosphere without technical complications. It is ideal for both cheap indoor grow tents and small to medium-sized greenhouses.
This refill is used to extend the operation of a CO2 Boost system, ensuring that the crop receives a constant supply of carbon dioxide. It serves to increase photosynthetic efficiency, improve plant resistance to adverse environmental factors, and achieve more abundant and homogeneous yields.
Its main function is to maintain a natural and safe supply of CO2 without the need for complicated installations.
The benefits of incorporating the CO2 Boost Cube Refill into a cannabis growing system are multiple:
Installing a CO2 Boost Cube Refill is a simple process. You only need to remove the depleted cube from the system, connect the new refill, and make sure the compressor and application tube are properly attached.
The system starts releasing carbon dioxide immediately, ensuring that the plants receive the necessary amount of gas to boost their growth.
The use of the CO2 Boost Cube Refill consists of replacing the empty cube with a new one in the CO2 Boost system:
With this system, CO2 release remains constant for 60 to 90 days, depending on the light schedule and crop usage.
Among the most outstanding advantages of this refill are the ease of installation, the prolonged duration, and the fact that it is a 100% natural system. It does not require handling compressed gases, does not generate additional heat or humidity, and is safer than other enrichment methods.
In addition, it is an ideal solution for those looking to maximize results in cannabis growing accessories with a simple and practical method.
