Exhale Homegrown CO2 XL - CO2 Bag for Indoor Grow Rooms & Tents - CO2 for Grow Tents - Foliage Mushroom Bag - 11 lbs.

Arrived as it should have, not inoculated because that's the one I purchased. Very easy to hang, and seems pretty solid. A lot of these negative reviews are from people that do not understand what they ordered. Unless you specifically order the one that says "self activated", then you will receive one that has already been activated. For the ones claiming they received a bad one because it has white "mold" growing inside, uh that's the stuff that actually produces the co2. It's called mycelium. This is an excellent way of adding some co2. It's effective if used correctly. If not used correctly, or if your environment or plant health is trash to begin with, then this will not work for you at no fault of the product. I have reordered another one, and will continue to order these, as they are a way cheaper and much safer way to obtain a co2 boost for your plants environment.

Great stuff, it took about three weeks to reach its max. Im using it in a 3×3 and my CO2 is ready well over 1700. My plants are eating it up and getting huge. I will be ordering more

Good.

Bought 2. Both don't produce ANY measurable C02. Trash.

It's been 10 days since installation. No increase in CO2 at all. Update So after 1 month it brings co2 up 200. So it does work

Lasted longer than expected grateful for soil

Bag leaked and had mushrooms growing on the outside,

Excellent product.

Used in a 5x5, actually a bit oversized for that need. Product is super though.

Prodotto non funzionante, già usato e completamente consumato.

Produkt Ablaufdatum endet im Dezember 22 somit keine 6 Monate

Das Produkt mag funktionieren jedoch nicht wenn der Verkäufer fast abgelaufene Ware versendet!!! Myzel ist grau und kaputt der ganze obere Teil feucht …. Frechheit

The bag dried up and stopped working after a few weeks waste of money and they always send out activated bags
