2 Liter Bottle

This product has been recommended by a friend and my plants are loving it!It's my second canister and I'll order refills to save money.

Convenient but it’s SUPER expensive for what it is. I feel like I just got duped for about < $2 worth of materials - however - the product does work. It’s just super expensive for what it is - so I’m rating low due to the VALUE. I hate the gouging. Great idea, generates CO2, but really expensive.We should just remember our high school science classes better - so thanks for the “Fool me once..”.

It says its supposed to produce co2 for 2 weeks but i did everything by the directions and it stopped hissing after i shook it by the third day. Other than that it is a big help in my tent.

This is my go to co2. Great product and works better than you'd expect. If you've yet to give this a try please do. You'll be more than pleased with the results this product adds to your yields. Remarkable!

I tried this and it does not affect my CO2 numbers at all! So annoying

hi

Not sure how great of a % these things work , but any added co2 will help plants

Only good for two uses
