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
Review: 5☆ - Provides a noticeable difference starting seedlings for spring planting

## Features

- SELF ACTIVATED - The ExHale 365 is a self-activated version of the Original CO2 Case. 365 will provide a 4x4 foot or 128 cubic feet with CO2 for 9 months, the highest production of 6 months. This product is perfect for small grow rooms and grow tents that want to produce more CO2 than you normally have.
- MAKE A LARGER EFFICIENCE EXPERIENCE - When used in conjunction with the original ExHale CO2 bag, grow rooms may experience 20% to 30% more growth. No heat or electricity required.
- Maintenance free - Simply place the ExHale bag slightly above the height of your plants in your growing area. If CO2 is heavier than O2, it will settle down against your plants. ExHale-Homegrown CO2 is a revolution in indoor CO2 production systems. Maintenance Free! CO2 Only! Proudly made in the USA.
- Perfect for most plants - ExHale can be used for both vegetable plant growth as well as for fruit and flower production. Put the ExHale CO2 Bag in your growing tent and let it do the job.
- Directions - Remove hangers from bag. Move the ovulation compartment slowly to the bottom of the bag, allowing the material in the upper ovulation compartment to fall into the sterilised sublayer below. Simply place the hanger over the filter patch and install it again. The Exhale bag can now be placed in your garden.
