Mushroom to add co2 ?

So if I understand right there’s some mushroom bags that you can buy to add CO2 to your grow area @ Can mushroom compost do the same ?

Unless you have your grow area sealed up properly Co2 is a waste of time. Those bags are a waste of time and money. If you're going to do Co2 you need to do it properly with an actual tank of Co2.
