Natural Co2 for indoor gardeners

To use your Turkey Tail sawdust block as a CO2 generator, simply put it in the same room as your plants.  Either hang it up in a plastic shopping bag, or put it on a shelf.  The block will continuously produce CO2 as a byproduct as the fungus breaks down the constituents of the sawdust. 
After 3-4 months, you can open the bag by cutting off the top of the bag at a line 1-2 inches below the top of the substrate.
