Exhale CO2 XL Grow Bag - Patented Mycelium Strain for Indoor Grow Rooms, & Carbon Dioxide Enrichment - XL CO2 for Grow Tents - Boosts Production for 6 Months - 11 lbs. (1 Pack)

Perfect like usual

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.

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.

So far the product has been working well for me, I was just disappointed in the quality. For 50+ dollars the bag shouldn't be ripped when you lift it out of the box.

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

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

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

Game changer helps plants alot

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.
