EZ CO2 XL Delay Activated CO2 Producing Mushroom Bag

EZ CO2 is a cheap, safe, and natural way to supply carbon dioxide (CO2) to your plants. A non-fruiting mycelial mass (fungus) and enough organic stuff are housed in EZ CO2 to last it for around six months. Together, the fungus and the plant have a symbiotic connection that allows the fungus to breathe in oxygen provided by the plant and release carbon dioxide 24 hours a day through the breather patch on the bag, resulting in a low-cost, naturally occurring CO2 generator. There is nothing to turn on or set up for EZ CO2, which emits no heat and is odorless as soon as you purchase it.
