We show you a quick method to measure your coco coir's EC to make sure that you are using the purest product available. We compare Mother Earth with Ugro using reverse osmosis water. It's worth pointing out that the best coco coir doesn't always have the lowest EC—that's because some manufacturers use buffering agents to aid with nutrient uptake—but this test gives you an initial "snapshot" of your coco growth media so you have some idea of what you're dealing with.
