With MyCO2 Kits, you can grow organic mushrooms after supplying your plants with months of natural carbon dioxide.
Give your indoor garden a boost using the naturally-produced CO2 made by mushrooms. As mushroom mycelium grows, it exhales CO2 (just like people!). Placing one of these Customer Activated MyCO2 kits close to your indoor plants provides the essential carbon dioxide that all plants need.
Each CO2 kit contains a filter patch bag filled with sterilized, amended hardwood sawdust (the substrate) and a select species of mushroom culture. To activate, you simply mix the mushroom culture with the substrate and form it into a block.
