ExHale XL CO2 Bag

Effortless Organic CO2 Enrichment for Your Indoor Garden

The ExHale XL CO2 Bag delivers continuous, passive CO2 enrichment to your indoor garden for up to 6 months without electricity, heat, or any additional equipment. Powered by a living mycelium culture contained within a vented bag, it naturally produces and releases CO2 around the clock through a microporous breather patch - matching the day and night rhythm of your plants. Simply hang it above your canopy in a 6ft x 6ft grow space (up to 288 cu ft) and let it work. Organic, maintenance-free, and made in the USA, the ExHale XL is the cleanest, simplest way to boost CO2 levels and support stronger growth and improved photosynthesis.

Key Features & Benefits

• Passive CO2 Generation - Mycelium culture continuously produces and releases CO2 with no electricity, heat source, timers, or additional equipment required.
• 24/7 CO2 Release - Provides around-the-clock CO2 enrichment, automatically reducing output during nighttime hours to match your plants' natural cycle.
• Covers 6ft x 6ft / 288 cu ft - Sized to support 6 to 8 plants through all growth stages from seedling to harvest.
• up to 6 months of Enrichment - Long-lasting mycelium culture provides extended CO2 supplementation without refills or replacement for most of the grow cycle.
• Built-In Hanger - Integrated hanging mechanism allows easy canopy-level placement so CO2 releases directly into the plant zone where it matters most.
• 100% Organic, Made in the USA - Natural mycelium and substrate system supports organic growing practices with no synthetic chemicals or combustion byproducts.
• Zero Setup Required - No assembly, installation, or equipment needed - activate and hang to start immediate CO2 enrichment.

Who Should Use This

The ExHale XL CO2 Bag is ideal for indoor cultivators who want simple, low-maintenance CO2 supplementation without CO2 tanks, burners, or electronic controllers. Perfect for home grow rooms, small commercial spaces, and any application where passive organic CO2 enrichment is preferred over mechanical systems.

Compatibility

No electrical connections or equipment required. Hang in the grow space using the integrated hanger at canopy height. Designed for enclosed grow spaces up to 288 cu ft (6ft x 6ft). For larger spaces, multiple units can be used together. Keep away from direct light sources to preserve mycelium viability. Store unused bags in a cool, dry location.

Frequently Asked Questions

How does a mycelium bag produce CO2?

The mycelium culture inside the bag naturally consumes the organic substrate and releases CO2 as a byproduct of its metabolic process - the same way fungi produce CO2 in nature. The microporous breather patch allows CO2 to escape steadily while keeping the culture contained inside the bag.

How do I activate the ExHale bag?

The ExHale bag is activated when you remove it from its sealed packaging and expose the mycelium culture to fresh air. No water, setup, or special conditions are needed - simply open the outer packaging and hang the bag above your canopy to begin CO2 release.

Can ExHale bags replace CO2 tanks or burners?

ExHale bags provide supplemental CO2 enrichment that can raise levels by several hundred ppm above ambient in a properly enclosed space. For maximum CO2 enrichment at high concentrations, dedicated CO2 systems offer more precise control. ExHale bags are best suited for supplemental enrichment in smaller enclosed gardens.

Does the CO2 output decrease over time?

Yes - the mycelium culture produces CO2 most actively during its peak growth phase and gradually reduces output as the substrate is consumed. This natural taper is a feature of the organic system. The ExHale XL provides up to 6 months of useful CO2 enrichment across its lifespan.
