           | You can grow mushrooms at home, it is fun. The only risk is
           | that the mushrooms with high spore production are not great

       | The problem is that it takes around 7 days for each piece of

       | 
       | For those reasons, mycelium packaging hasn't seen much adoption

         | Two packages made from mycelium can behave very differently
