So I was around 550 on CO2 level but after adding the exhale bag to my tent you can see from the picture it does what it’s meant to do. Would buy this again for sure.

I ordered from Growgreenmi and the bag never arrived. I ordered from HappyHydro in New York and my Co2 bag arrived in 3 days. Faster than they said it would. Excellent service. Will be ordering everything from HappyHydro in the future. Thanks

first, happy hydro has the best price on a product; better than amazon. having free shipping is outstanding. even better, the 'how to' video on where to place the product vastly improved the co2 measurement inside the tent according to the co2 meter. i plan to make a purchase every 6mos.
