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 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.
- MAINTENANCE FREE - Place the ExHale bag slightly above the height of the plants in your grow space. CO2, being heavier than O2, will precipitate downward towards your plants. ExHale-Homegrown CO2 is a revolution in indoor CO2 production systems. Maintenance Free! Just CO2! Proudly made in the USA.
- PERFECT FOR MOST PLANTS - ExHale can be used for both vegetative plant growth as well as for fruit and flower production. Put the ExHale CO2 Bag in your grow tent and let it do its thing.
- DIRECTIONS - Remove hanger from bag. Fold the top of the bag over and re-attach the separation seam hanger by placing it above the filter patch. The Exhale bag can now be placed in your garden.
