EZ CO2 XL Delay Activated CO2 Producing Mushroom Bag

EZ CO2 is a natural safe and inexpensive way of providing your plants with carbon dioxide (CO2). EZ CO2 houses a non-fruiting mycelial mass (fungus) and enough organic matter to sustain it for approximately 6 months. The fungus creates a symbiotic relationship with the plant: Breathing in oxygen released by the plant and releasing carbon dioxide (released 24 hours a day through the breather patch on the bag) creating a natural self-sustained inexpensive CO2 generator. EZ CO2 is odor-free produces no heat and is already giving off CO2 as soon as you purchase it there’s nothing to turn on or set up.
