What is the difference between Extended EM and Activated EM?
The term Activated EM, also called Activated EM-1, has replaced the term Extended EM (which was mostly used in North America). Most of the world has been using the term Activated EM which more accurately describes the process (See “How is EM applied? under ACTIVATION” above for instructions on making Activated EM). The reason for the change is because the term “extended” led some people to believe that EM could be extended or propagated out multiple times. That is, they thought that through the method of activation, they could continually culture EM on their own without having to buy more stock EM.
