## Description

The XL ExHale CO2 Bag is for medium to large grow spaces. The XL will provide a 6x6 foot or 288 cubic foot space with CO2 for 6 months . The XL ExHale comes with a freshness seal that doubles as a hanger. Features Include : Steady supply of CO2 for 6 months , Maintenance free, No heat, No electricity, Patent pending genetics, Suitable for Organic Production How to Use ExHale : ExHale comes complete, simply follow the instructions and place the ExHale bag in your grow space and leave it alone to do its job. A continuous shower of CO2 directly onto your plants is the most efficient way to deliver CO2. Placing the ExHale CO2 Bag slightly above the level of your plants will ensure they receive the CO2 they need 24 hours a day for up to 6 months. ExHale can be used for both vegetative plant growth as well as for fruit and flower production. If you have a ventilation system, place the ExHale bag in close proximity to the fresh air intake. CO2 will be drawn upwards through the canopy.

Review: Great product, does what’s described - Perfect like usual
Review: Great low cost solution to CO2 management - The ExHale CO2 system is exactly what I needed for my indoor grow tent. I needed to raise the CO2 levels in my grow tent, but was hesitant to purchase a full mechanical system or use a flame based system indoors. The ExHale back works perfectly since the fungus is light activated. The CO2 levels rise in the tent as the plants begin to wake up and does down once the lights go out. I have a 6X4X6 tent and this thing can raise the CO2 levels to 1600 PPM easily. I was initially worried about them being that high and found just placing it in a slightly shadier spot was enough to lower them back to a more acceptable level.

## Features

- TWICE AS MUCH CO2 - The Exhale CO2 XL bag is over twice the size of the regular Exhale CO2 bag. This means that the bags will exhale more than twice the amount of CO2 over the same 6 month lifespan, and can therefore cover a much larger growing space.
- EXPERIENCE 2X THE GROWING POWER - Grow rooms, when used in companionship with the Original ExHale CO2 bag, can experience anywhere from 20% - 30% more growth. Requires no heat or electricity.
- MAINTENANCE FREE - Place the ExHale bag slightly above the height of the plants in your grow space. CO2 being heavier than O2 will precipitate downward towards your plants. ExHale-Homegrown CO2 is a revolution in indoor CO2 production systems. Maintenance Free! Just CO2! Proudly made in the USA.
- PERFECT FOR MOST PLANTS - ExHale can be used for both vegetative plant growth as well as for fruit and flower production. Put the ExHale CO2 Bag in your grow tent and let it do its thing.
- DIRECTIONS - Remove hanger from bag. Fold the top of the bag over and re-attach the separation seam hanger by placing it above the filter patch. The Exhale bag can now be placed in your garden.

### ⭐ Waste of money
*by J***. on April 9, 2026*

If you’re looking to supplement your co2 you would have to have like 10 of these bags in a 4by4 tent just to get 800 ppm. I have 4 of these bags max co2 in my tent and it holds a 500 ppm.
