The ExHale 365 CO2 bag is the first real customer activated CO2 bag in the world. Still the most CO2. Still the longest life. Still the Original! Maintenance free, no heat, no electricity, just CO2!

ExHale CO2 365 Bag


The ExHale 365 series of CO2 bags has taken technology to the top, literally to the top of the original CO2 bag. Nestled safely inside the spawn pod is our award winning exhale strain.

Our multi patent-pending design utilises a separation seam that allows our spawn pod to remain active and also allows for specific timing of co2 production.

Retailers and end-users love the ExHale 365! With a guaranteed 3 months of distribution and shelf life, the ExHale 365 will be ready when you are. Once CO2 initiation has occurred, CO2 production will begin in earnest with peak CO2 production beginning after 30-45 days. CO2 will continue to be released for the remainder of 9 months.

With 3 months of shelf life and 9 months of CO2, you’ve got yourself a year! That’s the ExHale 365.

The separation seam also serves as a hanger. When you remove it, allow the material in the upper spawn pod to fall to the sterilised substrate below by gently moving the spawn pod down to the lower part of the bag.

Re-attach the separation seam hanger by placing it above the filter patch. The Exhale bag can now be placed in your garden. Use the grommet hole to hang the ExHale bag slightly above your plants.

Full production will be reached within 30-45 days. The ExHale 365 will produce CO2 for 9 months.

ExHale’s substrate is a proprietary formula designed to give the CO2 producing mycelium a food source for the long haul.


ExHale’s mycelium is a patented strain of non-fruiting, high CO2 producing fungi that love bringing nature back to indoor gardens.


Carbon dioxide (CO2) is one of the most vital components required for efficient plant growth. All plants require carbon dioxide to grow, and a lack of CO2 will result in slow and stunted plant growth.

Plants growing under artificial lighting often lack sufficient CO2 to efficiently photo-synthesise. ExHale CO2 Bags maximize CO2, helping the process of photosynthesis to increase the growth speed of your indoor plants, leading to better yields and healthier fruits.

ExHale CO2 is a revolution in indoor CO2 enrichment. Let your plants breathe naturally with ExHale.

The Exhale is an idea that brings an important part of nature back to the indoor garden, CO2. Indoor gardening is a complex business and hobby. To do it right all the needs of a plant must be taken into consideration and more times than not, in an affordable way.

The ExHale bag is a patented strain of mycelium that produces an abundance of CO2 without fruiting. This means that when our bag is activated, the mycelium grows, eating the substrate it comes with, giving off heaps of CO2 straight into your garden, and it does all this for 6 months – guaranteed!
