Exhale CO2 XL Grow Bag - Patented Mycelium Strain for Indoor Grow Rooms

The ExHale CO2 system is exactly what I needed for my indoor grow tent. I needed to raise the CO2 levels in my grow tent, but was hesitant to purchase a full mechanical system or use a flame based system indoors. The ExHale back works perfectly since the fungus is light activated. The CO2 levels rise in the tent as the plants begin to wake up and does down once the lights go out. I have a 6X4X6 tent and this thing can raise the CO2 levels to 1600 PPM easily. I was initially worried about them being that high and found just placing it in a slightly shadier spot was enough to lower them back to a more acceptable level.

Just a note since as it doesn't state it anywhere. The product came activated. The bag had holes and the mycelium was seeping out of the bag. Bag was also missing hanger. Not worth the hassle to go back and forth with shipping. Will tape wholes and use as is. Product works since it's not my first time using it. Best to buy it local and make sure you are getting it with a hanger and no holes.

Perfect like usual

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.

It did raise my co2 but my space is 12x10 a bit larger than recommend. I believe one more will bring it up alot more, but at least its over the 400 outside air. Was 330's ppm CO2 with bag in 3 days runs 450's ppm. I will wait a few weeks to see if it improves more before getting my second bag. The first day not noticeable but second day held right under 400 ppm. And now 450ppm. Be patient its not instant, but my numbers are accurate. Was using propane. But summer to much heat and moisture. This looks better for me

Works great but I think I get enough carbon on my own Not for small runs

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

If you’re looking to supplement your co2 you would have to have like 10 of these bags in a 4by4 tent just to get 800 ppm. I have 4 of these bags max co2 in my tent and it holds a 500 ppm.

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

Prodotto non funzionante, già usato e completamente consumato.

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

I received the product but the hangers are not included. Last time I ordered it came with hangers. Product description shows that it comes with Plant hangers.
