Mushroom CO₂ Bag – Natural CO₂ Enrichment for Indoor Growing

The Mushroom CO₂ Bag provides a simple and natural way to supplement carbon dioxide levels in indoor grow rooms, grow tents, hydroponic environments and greenhouses.

Designed as a passive CO₂ source, the bag uses naturally active fungal mycelium to release carbon dioxide over time. There are no gas bottles, regulators, electricity or complicated equipment required, making it an easy, low-maintenance option for growers looking to support a CO₂-enriched growing environment.

How Does It Work?

Inside the bag is an active mycelial culture growing on an organic substrate. As the mycelium naturally respires, it consumes oxygen and releases carbon dioxide into the surrounding air.

Plants use carbon dioxide during photosynthesis, so maintaining suitable CO₂ availability—alongside adequate lighting, nutrients, temperature and airflow—can help support healthy plant development and productive growth.

Important Note

Actual CO₂ concentration and coverage will vary depending on the size of the growing area, ventilation rate, airflow, temperature and surrounding environmental conditions. For best results, monitor growing conditions and ensure plants receive appropriate lighting, nutrition and ventilation.
