ExHale CO2 EX50002 Exhale XL CO2 Bag

Great item

Should the activator be liquid? I've used the standard size bags and the activator in the top of the bag is a solid mass to mix in. Got this XL bag and it was liquid and leaked a little. Mixed it and hope it works anyway but it didn't look normal...maybe got hot..squished...? I'll get bags from the grow stores from now on.....

Does exactly what it's supposed to do my plants love this product it works very well.

I bought the ex large co2 bag. The spore print and substrate divider was already removed by someone, the great news is "mushroom process" was already in action as the substrate was already getting white, so i mixed/kneeded the entire bag rigerously and the next day half bag was getting white ..so i mixed/kneeded again and in 1 week since i received from Amazon i have solid mass of Mycelium..paid 43 bucks for bag which was cheap at the time..now 60- 70 bucks for EX large bags. No matter what you do, if you want success in the garden use co2, with these bags its a no brainer.

Great product, came on time. Lasted for 4-5 months.

I could not notice a difference. Bag came with a tear in it and it was dried out

Works for my 4x8 grow tent.

Bag came with holes in it and some watery substance spilled in the box. Set up the bag in the tent as per instructions. After weeks, CO2 PPM in the grow tent is still the same as ambient air . <500ppm . Won't buy again.
