Pack of 10 CO2 Exhale Grow Bags Growing Tents Hydroponics Carbon Dioxide Large Yields 5-15 m2 Area

Around 2 weeks each bag. Good little way to get co2 in the grow. Won’t find this cheap anywhere either.

Boosts CO2.

thank you

Easy to use

Excellent value for money. My co2 meter is picking consistent levels above 1200 ppm. Will be buying again. Shame there isn't a bigger version!

Did not find any difference with these

Fantastic product for the price which surprisingly works. My plants react noticeably well to this, your environment needs to be right though so if you follow VPD and ensure your temps and humidity are correct this product will work wonders.

Before buying, you should know: 1. These are meant to be hung, but there is no mechanism to do so - no hole, nothing to tie it to anything 2. It needs to be above 25° - not 18° they say on the Product info. I don’t want my tent that hot 3. You have to manually punch holes in the product to release its magic, but you also need to be v careful not to come into contact with the contents - so it’s a bit of a risk and, if the contents are harmful to skin, what do they do if spilt on the plants? 4. “CO2 production can result in moisture in the bag, pierce bag at bottom with a pin to allow moisture to escape” - so another risk of getting the caustic contents everywhere? What a terribly, awfully designed product.
