Salai Bags bags with an “MM” filter are designed for fruiting blocks.  Fill with supplemented bulk substrate then sterilize in an autoclave or pressure canner.

Once cool, inoculate with grain spawn in a sterile lab or “still air box”, then seal with an impulse heat sealer/bag clamps or zap strap.  Shake to mix the mushroom culture throughout.  The filter patch allows for air exchange while keeping contaminants out during colonization.
