Because Nature Mycelium CO2 Generator utilizes Shiitake mushroom mycelium to generate additional CO2 for your grow area for months. Inside your bag is a living Mycelium culture growing on a sawdust substrate. Just like us humans Mycelium inhales O2 and exhales CO2 . This is great news as C02 is a vital gas your plant requires to be able to photosynthesize.

Because Nature Mycelium CO2 Generator Small bag should provide enough additional CO2 for a 1.8 m x 1.8 m x 1.8 m area for 2 months.

The Mycelium in your bag will consume the O2 waste from your plant and in exchange produce CO2 for your plants, allowing them to photosynthesize at their best.
