4. High Salinity Content

Initially, the electrical conductivity level or salt content of coco coir is between 2 and 6 mS/cm, which is far too high for a growing medium. High-quality coco coir ought to be properly washed until the E.C. falls below 1mS/cm, but if you landed on lower end products, the chances are the peat isn’t washed enough, and the salt content landed on the higher end, which can lead to several bad effects to plants.
