Co2 in a bag - Anyone use? +rep

Heya, I picked up some fermenting mushrooms for $35. Guy at the store said its supposed to last around 6 months and people have been reporting co2 ppm 1000+ in grow tents?

Anyone use this before? I didn't open it since it says "do not remove filter" so I assume it was already active in the store and it slowly seeps out? I just hung it 3 feet above my intake fan so it hopefully sinks down and then gets blown into my plants.


Thanks for checkin~

Ive seen those clear bags that have a little filter/screen on them. A friend is using them right now but I haven't asked how they are doing! the bag starts out half full of stuff then (I think he said they last 2 monts???) the bag starts to puff out and look full. I think it is pretty much someone selling their once diy co2 kit.

i been tempted to try 1 myself, mind you the only way to know if it's doing it's job & that's having a co2 monitor in there, be interested to hear your results

A friends friend is getting great results.master bedroom closet for your imagination.
