It is possible to locally source the strains to make your own Efficient Micro-organisms. This still requires to master the process. Here is a link to try out/experiment this process (link). The easiest way is to order the strains online. In France, you can order them through Bertrand Grevet, an expert on the EMs. There are two types of Ems: - EM 1: these are concentrated strains that require one step before use : activating them with treacle / molasses ; - EM A (for Activated Efficient Micro-organisms): the activation through the mix with treacle has already been done, however their shelf life is short (about 1 month). It is still better to source EMs A rather than EMs 1.
