Exhale Homegrown CO2 Micro - CO2 Bag for Indoor Grow Rooms & Tents - CO2 for Grow Tents - Foliage Mushroom Bag - 1.5 lbs.

This bag activated roughly fast with the mycelium growth, I was expecting it to be much bigger but it's honestly all I need for the plants in my tent and it's working beautifully

Thanks great product and packaging

For starters, there was no hanger (which is needed to properly hang). Secondly, there was no spawn pod (mycelium spore) to mix with the substrate. The bag seems to have been activated already upon arrival. All I can do is wait and see if it works. Buy the bigger bag and get your money worth, your garden will love you for it, this bag is very tiny, much smaller than I imagined it being.

Expiration date showed it was expired when it came. However the material on bag looked fresh. Over time the brown material will grow mushroomy(white clumps) shows it is sucking in oxygen and kicking out the CO2 your looking for. Occasionally you may want to squeeze the bag and break up the brown material to allow more exposure to the oxygen so more CO2 can be released. Eventually whole bag will be filled with the white clumpy mushroom material. In which case it would be time to get another bag if you want to keep your plants exposed to more natural CO2.

Took creativity to find a way to hang the bag in my grow tent. Will see how it all works out.

Bought this as an experiment after having a conversation with a friend about using c02 in my grow tent, was skeptical but this bag has taking my plants from little guys to adults fast

Added this to my grow tent. Wow, what a difference in the growth rate. Would recommend this product to increase growth.

The media could not be loaded. I was only worried about the bag being either contaminated or over fed, but it came in perfect condition for my babies (: wish I got it sooner but it’ll probably feed into my next grow early on!
