Review: Replacement order was as expected. - So the first 365 bag I received appeared mostly used up, as the mycelium had already colonized the substrate. I requested a replacement which came promptly and the second bag looks fresh with no colonization. I will update this review for performance in a few weeks but as of now I have high hopes for this product. UPDATE!! So I posted a picture of the numbers I'm getting from my tent after one week with the new bag. These bags appear to be very effective just make sure it shows up fresh and not partially populated. Good product

This product is great for small grow rooms and grow tents that are looking to produce more CO2 than what you’d normally have.
- EXPERIENCE A LARGER YIELD - 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.

### ⭐⭐⭐⭐⭐ Works as intended
*by R***. on May 12, 2026*

People told me these dont work. My co2 meter says otherwise. Normal readings 500-600 & after introducing the bag (one week later) it jumped to 800-900 depending on exhaust speed. Its been 6months & still going strong!
