Exhale CO2 EX50003 365-Self Activated CO2 Bag, 365

This is a quality product, my plants appreciate it.

I'm on my second grow using the same grow bag.... I am keeping 1500 ppm in a 5x5 grow tent with 8 small ladies in it.... when they get bigger they use more, so expect that number to fall a bit as the plants grow..... Note: 2000 ppm or more is toxic to plants and 1400-1500 ppm is optimal so I am pleased.......Now the bad stuff.... I did not notice an effect during my first grow.... The bag may have been adding Co2 better near the end of the 90 day grow, but i couldn't tell as i had other Co2 methods in play at the end. When i put some smaller plants in the tent on my second grow,I have Co2 alerts on my phone with the grow bag alone.... What I am saying is it has a long ramp up time, but the fact it can set off my alarm alone is impressive.... Hope this review helps you. :)

Works great!

Definitely helps

This was the third time this item was exchanged because it was opened and ruined I will never buy again I used this product for a long time and now it seems like it's on purpose zero stars if it would let me

This is the one to buy for your tent. Not the other brand.

I feel like my plants would have benefitted from the CO2 bag but sadly only days after activating it, the smell permeated the grow room. Even when filtered, the air smelled strong of ammonia which, for me, made the grow room difficult to be in which is not preferrable. I do wonder if perhaps I got a bad one, but the smell makes me weary of trying again. I would like to use this product if this is a one off and the manufacturer reads this, I'd be happy to try again after being contacted.

We've been able to use 1 bag for multiple grows. Plants are vibrant and healthy. Easy to use, set it and forget it.
