New, novel strains of mushrooms are created when starting from spores.  You could discover the next popular strain of your favorite variety when growing mushrooms this way.  Even better, spore prints are more resistant to extreme weather.   

Each spore print order includes 2 prints on separate pieces of tinfoil, packaged in individual plastic bags. Commercial spore prints are taken from commercially viable mushroom strains.  Spore prints are taken in sterile lab conditions from indoor grown mushrooms, but note that spore prints are not guaranteed to be 100% sterile due to the nature of how mushrooms grow, and how prints are taken.  We recommend adding spores to agar petri dish plates to isolate potential contaminates and the desired strain.  We take every precaution to make the cleanest spore prints possible.
