Exhale Homegrown CO2 365 - Self-Activated Bag for Grow Rooms & Tents - Great for Indoor Grow Rooms - 4 lbs

Good.

Works great. I have bought again.

I don’t know the specs on the actual CO2 added but my plants look good. It took around 3-4 weeks to fully activate but that was expected. It worked exactly as it should.

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

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.

Used in a 2x2 tent with humidifier for two peppers and two basil plants, no difference over a few weeks of use - followed instructions to remove hanger and drop spawn into media and rehang it

The bag works seen more growth on all my plants

Bag leaked and had mushrooms growing on the outside,

Produkt Ablaufdatum endet im Dezember 22 somit keine 6 Monate

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

Bonjour sur les deux exhale bag il n’y en a qu’un sur les deux qui c’est activé, il n’ai pas devenue blanc comme l’autre depuis que je l’ai acheter il n’a pas changé de couleur et il ne dégage presque pas de CO2 contrairement à l’autre qui produit la quantité normale de co2 vue le prix je suis dégoûtée la prochaine fois je les achèterai sur un autre site car sa fait environ 60 euros j’étais par la fenêtre. Bref je suis dégoûté .

Took around a month to fully activate, its pumping along now. Impressed.

Would definitely recommend these mine’s only been in there for less than a month and it’s incredible. The difference it made I’ve done three small girls without these and wow can you see the difference?
