Exhale CO2 365 Self-Activated 4 lb Bag for 4x4 Grow Tents — 9-Month Output, Maintenance-Free

Exhale Homegrown CO2 365 is a self-activated, maintenance-free 4 lb CO2 emission bag that supplies supplemental carbon dioxide to a 4x4 ft (128 cu ft) grow space for up to nine months, with six months of peak output.

The Exhale 365 is designed for small to medium indoor grow rooms and tents that need a steady CO2 boost without wiring, heating, or daily attention. Ready to use out of the box, the bag releases CO2 continuously after activation and includes a separation seal that doubles as a hanger. It’s formulated for routine vegetative and flowering stages and can be positioned near fresh air intakes or slightly above the canopy for best distribution.

How long does one Exhale 365 bag provide CO2 and when is output highest?

One Exhale 365 bag delivers CO2 across a 9-month period; production peaks for roughly six months and tapers for the remaining time. It also includes a three-month shelf life prior to activation, giving you about a year of total usable time between storage and active output.

• Active CO2 coverage: up to 9 months
• Peak production window: about 6 months
• Designed coverage area: 4x4 ft (128 cubic feet)
• Up to 12 months total life including 3-month shelf life

How do I activate and place the Exhale CO2 bag for best results?

Activation is straightforward: collapse the upper spawn pod to allow the active material to fall to the sterilized substrate, then secure the included hanger above the filter patch. Place the bag slightly above the canopy or adjacent to a fresh-air intake so CO2 naturally drifts down through the canopy and reaches plant leaves continually.

• Remove hanger, move spawn pod down to mix components
• Re-attach separation seal as the bag hanger
• Position above canopy or near ventilation fresh-air intake
• No electricity, heat, or ongoing maintenance needed

What changes can growers expect when using Exhale 365 in a tent or room?

In properly used systems, supplemental CO2 from Exhale can support stronger photosynthetic activity during the light cycle, often translating into improved growth or increased yield potential. Results vary by strain, lighting, nutrients, and environment; Exhale is intended to be one part of a balanced cultivation setup rather than a standalone solution.

• Compatible with vegetative and flowering stages
• No added heat or power draws to the grow environment
• May complement other Exhale products for larger spaces
• Suitable for organic production environments

Is the Exhale bag easy to use and maintain in a home grow setup?

Yes — the Exhale 365 is designed for minimal handling after activation. It’s packaged for consistent performance and built to require no daily upkeep, making it suitable for growers who want a passive CO2 source without mechanical systems or constant adjustments.

• One-time activation is all that’s required
• Maintenance-free operation for the active period
• Made in the USA with consistent packaging and materials
• Patent-pending formulation for reliable CO2 release

Who is this for? The Exhale Homegrown CO2 365 is aimed at hobbyists and small-scale commercial growers using 4x4 ft tents or similarly sized rooms who want a reliable, hands-off CO2 supplement. It’s particularly useful where adding heaters, timers, or compressed CO2 systems is impractical or undesirable — for growers seeking a simple, organic-friendly CO2 option to pair with existing lighting and ventilation setups.
