- You are scaling up your small tent canopy because you need a continuous CO2 source that runs without gas lines, cylinders, or burners.
- You are automating your small grow space because you want passive enrichment without managing timers, heat, or daily equipment setups.
- The fungus inside the bag consumes plant oxygen and releases CO2 around the clock through the breather patch.
- Each bag contains enough organic matter to sustain the mycelial mass for approximately six months.
- The organic matter inside the bag sustains a non-fruiting mycelial mass that generates CO2 without any mechanical components.
- Growers running these bags in enclosed spaces say they appreciate having a CO2 source that produces no heat or detectable odor.
- Hobbyists setting up small tents say they value a passive enrichment method that requires zero setup or equipment connections.
EZ CO2 Delay Activated CO2 Producing Mushroom Bag
CO2 enrichment doesn't have to mean gas lines, burners, or pressurized cylinders. The EZ CO2 Mushroom Bag takes a completely different approach: a living, non-fruiting mycelial mass housed inside a breathable bag, sustained by enough organic matter to produce CO2 continuously for approximately six months. The fungus forms a symbiotic relationship with your plants — consuming the oxygen plants release and returning CO2 through the bag's breather patch around the clock, 24 hours a day, without any input from you.
There is nothing to set up, no equipment to connect, and no heat or odor produced. The EZ CO2 bag is already actively releasing CO2 when it arrives — just place it in your grow space and it goes to work immediately. For hobbyist growers and small tents, the EZ CO2 bag delivers passive, natural enrichment; however, if you are managing a larger canopy, you might consider the EZ CO2 XL Delay Activated CO2 Producing Mushroom Bag for increased output at a fraction of the cost and complexity of traditional CO2 solutions.

Features
Living Mycelial CO2 Source
A non-fruiting mycelial mass sustained by organic matter inside the bag naturally produces CO2 as a byproduct of its metabolic process — no mechanical components required.
Symbiotic Plant Relationship
The fungus consumes the oxygen your plants release and returns CO2 in exchange — a self-sustaining cycle that enriches your grow space naturally and continuously.
24-Hour CO2 Release
CO2 is released continuously through the bag's breather patch around the clock — unlike burner-based systems, enrichment doesn't stop when lights go off.
~6 Months of CO2
Each bag contains enough organic matter to sustain the mycelial mass and produce CO2 for approximately six months — covering a full growing cycle for most crops.
Zero Setup Required
The bag is already actively releasing CO2 when it arrives. No assembly, no connections, no controllers — place it in your grow space and it begins working immediately.
Odor-Free & No Heat
Produces no detectable odor and generates no heat during operation — safe to use in enclosed grow tents and small spaces without affecting ambient temperature or air quality.

Frequently Asked Questions
The bag contains a living, non-fruiting mycelial mass — a fungal culture — sustained by organic matter sealed inside. As the fungus metabolizes the organic material, it produces CO2 as a natural byproduct, which then escapes through a breather patch on the bag. The fungus also consumes the oxygen your plants release, creating a continuous back-and-forth exchange between the bag and your plants.
No. The mycelial mass inside is a non-fruiting strain, meaning it will not produce visible mushrooms or caps under normal conditions. The bag is also odor-free during operation, making it suitable for use in enclosed grow tents or indoor spaces where odor would be a concern.
The EZ CO2 bag produces CO2 at a much lower and passive output rate compared to burner-based systems like the LTL Controls CO2 Generators, which are designed for rooms of 600–1,300+ square feet. For those seeking a different application format, EZ CO2 Pads offer another convenient way to introduce carbon dioxide into your environment. The mushroom bag remains best suited for small grow tents and enclosed spaces where passive supplementation is the goal, requiring no equipment or fuel.
Each bag sustains active CO2 production for approximately six months, after which the organic matter inside has been largely consumed by the mycelium and output drops off. Signs of depletion include the bag becoming noticeably lighter and less firm as the internal substrate breaks down. At that point, the bag can simply be replaced with a fresh one to continue enrichment through the next grow cycle.
Position the bag at canopy height or slightly above, near the center of the grow space, with the breather patch facing outward and unobstructed. Since CO2 is heavier than air, placing it higher allows CO2 to settle naturally down through the canopy. Avoid sealing the bag against walls or other surfaces that block airflow around the breather patch, as this can restrict CO2 release.
For small to medium grow tents — typically up to 4' × 4' or 5' × 5' — one bag provides meaningful passive CO2 enrichment. Larger spaces may benefit from multiple bags placed at intervals throughout the canopy to distribute CO2 more evenly. For rooms exceeding a few hundred square feet where consistent, measurable CO2 concentration targets are required, a dedicated CO2 generator system will deliver more reliable and controllable results.
