*3.5.1 Multiplied (M-) EM*

Stock EM is multiplied to reduce cost. Multiplied-EM is a mixture of stock EM with molasses and water in a ratio of 1:5:94. After mixing the ingredients, the resultant solution is stored in an airtight container for between 10 and 14 days between 20 and 25°C until the pH is 3.7. During this time, the microbes enter a growth phase and multiply to reach a microbial population and composition like that of the stock EM. To maintain the quality of multiplied EM, they should be stored between 10 and 20°C [35, 36].
