Review: THEY WORK GREAT FOR GROW TENTS & SMALL GROW SETUPS - I've purchased several of these in the past few years , and have had different levels of c02 output . I have always used anywhere from 2-6 of them at a time . I've found that they work the best in an environment that has medium humidity (35-60%) and good air flow . I have 4 small fans running and a CFM exhaust fan pulling a decent amount of air through the tent . I purchased a highly reviewed meter to monitor my c02 , and its been enlightening to watch these bags put out some high numbers . I was shocked when I finished up my first grow , and seen I had nearly 1400 ppm . I then saw that all 3 bags were in perfect activation. , The bags had been really been supplying a substantial about of c02 all along , even though my meter was showing lower numbers mid to late in flower . The trick is purchase 1 or 4 and activate at the start of a grow . I have seen my numbers rise a little in the first 4 weeks after activation, but the magic REALLY HAPPENS ONCE THE BAG IS PUFFED UP . It usually takes at least 30-40 days before these are really starting to work optimally. ( This is just from my personal experience ) CONS- I have had a couple show up damaged before , from transport I assumed . I had an XL sized c02 bag show up that never seem to really get with the program. It changed to white and showed familiar activation symptoms , but always just limply flopped over at the top . I could see someone , first purchasing a bag , possibly having a little trouble figuring out how to activate correctly and hang , but really you just gotta follow the instructions. Its quite simple and easy . Altogether , this is an amazing product . I'm sure there are home remedies to achieve c02 output , but these bags have absolutely been effective in my setup. I wish they were a smidgen cheaper , but I understand people need to make a living . One day I might upgrade to a tank system , but in the meantime these nifty C02 mushroom bags will do.

## Features

- GREAT FOR SMALL GROW ROOMS - The Original ExHale CO2 Bag will provide a 4x4 foot or 128 cubic foot space with CO2 for 9 months, of which 6 months are peak production. This product is great for smaller grow rooms and grow tents that are looking to produce more CO2 and catalyze growth.
- EXPERIENCE A LARGER YIELD - Grow rooms, when used in companionship with the Original ExHale CO2 bag, can experience anywhere from 20% - 30% more growth. Requires no heat or electricity.

### ⭐⭐⭐⭐⭐ Helpful on flower
*by 4***Y on January 1, 2026*

It helped to get the nuggets tight

### ⭐ Came ACTIVATED and CAME WITH SPIDER MITES!!!
*by O***G on August 4, 2022*

So in July we were going into a heat wave here in the northeast so in anticipation I got one of these 4 my tent. I opened the box and saw the block was already kinda white n then after reading the instructions I realized it was already activated. I assumed they sending them out like this on purpose because they assuming ppl aren't seeing them up correctly. I placed it into my tent and for the first few days my cannabis plants (which were in bloom) were very happy n beautifully green n I tested the co2 in my tent and yes it was up by 400 ppm. But after about a week the number dropped back down which has me wondering if the product was somehow defective and at the same time started noticing stippling on some of my leaves. Now everyone knows that u really can't apply any solutions to blooming cannabis but I wasn't about to have 9 months of growth and labor go 2 waste. Needless to say the pictures tell it all. It didn't work against the heat stress plus setting up environment that those little buggers LOVE. Luckily the second picture is of my 1 plant that was still in veg in my other tent which caught the infestation. Now the second I'm sure I can bring back since it didn't flower but it'll take a while but my first 2 babies I'm starting to believe are hopeless. FIX UR QUALITY CONTROL ISSUES!!!! If ur looking for co2 check YouTube thru have plenty diy solutions
