Sometimes we overheard consumers complaint about ineffective ‘effective microorganism (EM1)’ solution. There are a few tips I would love to share with you on how you can determine the quality of EM1 that you just bought.
Different materials have different density. Water density = 1kg/L, molasses = 1.5kg/L. So if the vendor had diluted your EM1 with 20%-40% of water earlier, you might notice the density is different with normal range.
