ExHale CO2 EX50003 Exhale 365-Self Activated CO2 Bag, 365

Well the proof is in the pudding or the pot! Love these bags! Get consistent Co2 levels throughout the entire grow. Bags last for several months producing 1000-1500 ppm levels of Co2. I run these Co2 bags in my clone/veg area as well as my flower area. Plants can take more heat stress with higher levels of Co2. The lights can now be closer to your buds and maxing out there available PAR. I have had nothing but happy plants with large yields. I run recirc air and have tight seald grow environment. If you want a "rain system" for Co2 get ready to spend big $$$. You will deal with Co2 tank & reg problems like costly fillings and leaks. I really enjoy this passive system as I do not have to constantly spend $$$ every week to refill my Co2 at the welding shop. So if you're a budget grower who likes discreet low maintenance options go with the Exhale 365 Co2 bags!!!

It works. Thought it might have a problem with the white innoculant above the bar but ,w hen ihe hanger bar was moved to open the window and I pushed the white spore strip into the chips after a week the whiteness spread.It does help with growth and flowering so was money well spent

This is a quality product, my plants appreciate it.

It's been 10 days since installation. No increase in CO2 at all.UpdateSo after 1 month it brings co2 up 200. So it does work

I'm on my second grow using the same grow bag.... I am keeping 1500 ppm in a 5x5 grow tent with 8 small ladies in it.... when they get bigger they use more, so expect that number to fall a bit as the plants grow..... Note: 2000 ppm or more is toxic to plants and 1400-1500 ppm is optimal so I am pleased.......Now the bad stuff.... I did not notice an effect during my first grow.... The bag may have been adding Co2 better near the end of the 90 day grow, but i couldn't tell as i had other Co2 methods in play at the end. When i put some smaller plants in the tent on my second grow,I have Co2 alerts on my phone with the grow bag alone.... What I am saying is it has a long ramp up time, but the fact it can set off my alarm alone is impressive.... Hope this review helps you. :)

Junk, does not work at all . Waist of time and money! Had a replacement sent and it was the same. 1st bag was expired no increase at all even after two weeks. Same thing with replacement. Refunds are slow and take 30 days for a product that does not work and it’s on the expensive side too! Never Again - U been warned. Professional co2 reader with sensor was used.

So I'm giving this 3 stars because the bag works. My plants were Noticeably Larger. Like Way Larger. However, I run 2 tents. So I put this bag between the tents on the floor near both intakes so they both would share the CO2. Which also worked perfectly fine because of the size of the room. However. The Bag leaked from the bottom. And a bunch of fungus grew into my carpet. Couldn't get it out without hacking the carpet apart. So If the bag works. It works well. If its faulty, It may do damage to your home by spreading its contents around.

The best thing about these co2 supplements is the packaging. The spores come segregated within the grow bag, and you decide when to introduce them to the bulk of the grow medium. That way you can store them until you are ready to use with out losing useful life of the material. Also the sturdy plastic is better at resisting tears than others. Finally the grow bag is easy to install with just a common hanger as opposed to others I’ve had to retrofit with tape for ripped plastic, clamps and special hangers .
