MyCO2 - Mycelium Derived Carbon Dioxide are CO2 bags perfected. Unlike all the other CO2 bags that "come cultivating CO2 even before you get out of the checkout line," MyCO2 has the patent pending customer activation technology, postponing the CO2 cultivation until you get it home and are ready to use it. One CO2 bag provides enough carbon dioxide for flowering or vegging plants in a 4 ft x 4 ft grow tent with cycled exhaust. Use during the Bloom during the flowering stage. Use during Grow during the veg stage. We recommend safely placing multiple MyCO2 bags above the highest level of your plants to insure they receive the CO2 as it is generated.

Stuff No Good
I purchased 2 boxes delivered June 1.. I put the first into service on June 5. I purchased a CO2 monitor, which I have used to measure the CO2 levels. The monitor works fine & has been checked against another monitor (within a couple numbers). Bottom line, No Increase in CO2 levels. I placed the second box in service June 16th. Still no increase by June 20th. As a matter of fact, I have higher levels in my office, than I do in my grow tent. These products DO NOT WORK. I would not recommend this product to anyone, even those I dislike. I am in the process of returning the boxes.

Not sure what happened, but this wad a waste of money
My meter never showed any co2 and after a month I had 1 mushroom and little else to show for it (never registered any recognizable co2).I've never had a problem with one of these before. Bunk shrooms.

Be careful!
This is a cool idea, but the flimsiness of the cardboard and way to secure it hanging is somewhat awkward and unstable. It has fallen many times in my grow room damaging buds, flowers and plants.

Save your money for something that works!
Totally worthless! I took a shot to see if this would improve the flowers on my plants, but got nothing. Nothing grew inside the bag, so I'm sure nothing came out. It was nice to experiment, but it was a waste of money.

Short Life Cycle But Good Results
Noticed a difference, but within 6 weeks the shrooms literally were growing out of the bag and box. Didnt last very long.

Unsure - mine was already activated
Mine came activated. The compost is not supposed to have any mycelium growth, but mine had a lot! I'll update this post if I get another one.

It works okay would be better if my grow room was in a tent
