Jim Read walks you through the simple steps of indoor mushroom cultivation using brown rice flour & vermiculite. If you want to try the NinjaAlex420 substrate method simply substitute vermiculite with wood chips & add a pinch of maple syrup or molasses to the added water (a sugar broth). I may make a video in the future for this method.
