CO2 Exhale HomeGrown – 100% natural carbon dioxide supplement

An efficient and maintenance-free solution for adding CO₂ to indoor growing

CO2 Exhale HomeGrown is a revolutionary way to introduce natural carbon dioxide into your growing environment without electricity, hoses or maintenance. The bag contains a mycelium growth that releases CO₂ steadily, promoting photosynthesis and improving yields.

✔ 100% natural – no additives or chemicals
✔ Automatically releases CO₂ 24/7
✔ Enough for up to 5 plants in small to medium-sized grow boxes
✔ Service life up to 6 months
✔ No electricity, pumps or controls – completely maintenance-free
✔ Place only above plants – CO₂ will naturally sink downwards

How does CO2 Exhale work?
The mycelium in the bag produces carbon dioxide, which is released through microscopic holes in its surface. The CO₂ settles on the plant leaves, where it enhances photosynthesis – and thus plant growth, health and yield.

Usage tip: Place the bag as high as possible above the plants, for example at the top of the growing box.

✔ The perfect choice for growers who want to maximize their yields naturally and easily!
