Description

CO2 Boost Self-Activated Bag for Plants – Version 2.0

9–11 Months of Natural CO₂ Output + Surprise Gourmet Mushroom Harvest

Take your indoor garden to the next level with the CO2 Boost Bag 2.0—a self-activating, long-lasting CO₂ enrichment system designed specifically for grow rooms, tents, and indoor plants. Powered by a proprietary strain of gourmet mycelium, this 5-pound bag releases high levels of carbon dioxide for 9 to 11 months without producing any mushrooms… until it’s time.


How It Works:

When activated, the mycelium inside the bag begins consuming the nutrient-rich substrate, emitting continuous CO₂ directly into your grow space. This enhances photosynthesis, boosting growth and yield. Most growers start noticing improvement within the first 7 days.

On the 10th month, the mycelium begins to fruit—producing a rare, delicious oyster mushroom that tastes like a mix of shiitake and buttery blue oyster with a steak-like texture. Just cut off the top of the bag and enjoy the gourmet reward.


Proven Benefits for Indoor Plants:

  •     Boosts CO₂ levels by 600–800 PPM in 5x5’ grow tents
  •     Ideal for vegetative growth and flowering stages
  •     Supports 4–6 plants in small to medium grow setups
  •     Increases yields by up to 30% and can cut harvest times by 18%
  •     Works with all plant types, from houseplants to produce
  •     Can revive struggling or slow-growing plants

What’s Included:

  •     (1) 5-lb CO₂ Boost Bag (Self-Activated)
  •     Step-by-step activation instructions
  •     Retail packaging for easy storage or gifting

Activation is Simple – Takes 60 Seconds:

  1.     Extend the bag.
  2.     Mix the colonized grain with the substrate inside.
  3.     That’s it! CO₂ production begins immediately.

Bonus Mushroom Variety Info:

  •     Kingdom: Fungi
  •     Division: Basidiomycota
  •     Class: Agaricomycetes
  •     Order: Agaricales
  •     Family: Pleurotaceae

3D Reality X
Grower's Delight!

I LOVE this CO2 bag. I bought mine back in August 2024 and has been through 2 grow cycles. I live in a legal grow state up north to help paint the picture. I have a friend who grows manure loving mushrooms and taught me what to expect. The time frame given by Myco Labs is accurate and I don't have any moldy spots and the whole bag is a nice solid rock. No shrooms yet!

In the grow tent setup I did my research and started this bag about 3 weeks into my first grow so in a way, I trained the mycelium to work with the environment it will live in. The humidity in the bag does get a little higher than in the tent as you will see wet spots here and there ESPECIALLY running 65%+ humidity during your veg cycle. I have my bag suspended to the side of the light. The light will hit the bag and what will happen is a slowed growth in that area where the light is but no need to worry! Keep the environment right and you will be fine!

Most of the growth in my case started behind the bag as it was mostly dark/shaded but i would see little zones in the front. Lastly during your drying phase, the bag will do great which is the whole purpose of training it from the beginning to teach it how to handle low humidity when needed. Once i finished drying i put my humidity back up 63-65% and began my next grow and this one is HUGEEEEE.

Morale of the story - As long as you train this early it can handle a growing environment. For me I'd like to clone in the future if at all possible but very happy with this and the price point is great!

Easy to use!

Activated my bag in a few minutes and it started colonizing inside within a few days. The bag slowly expanded and puffed out after about a week to 10 days. It appears to be moving along pretty well. I currently have it in my sun room where I have 10 different plants. I bought this mainly for myself and a fun project to try and I am very excited about the mushrooms that they say will grow down the road. Hopefully my plants enjoy a little extra Co2 in the meantime! Will update new review if I see any difference in my plants in a few weeks.

Finally an alternative!

Works, Co2 meter reads 300 points higher with 1 bag, adding a 2nd gave me 650 ppm increase in my 5x5. Similar to other Co2 bags ive bought in the past. Really cool that they actually produce mushrooms, I dont think they will, but hey prove me wrong!

Finally another option!

Been buying Exhale bags for years for my Green medical grow room. I happened to stumble upon these while buying mushroom supplies for my latest hobby and decided to pick one up. I can say these work exactly the same as Exhale but I am super stoked for harvesting some shrooms later as well. I would not buy these for the sole purpose of growing mushrooms bc they take forever but if you have plants too, this is a great and easy "Set it and forget it" product. I would recommend buying 2. I always noticed the best results from using 2.
