The E-value was devised to help answer a horticulturists question “How quickly will a mix dry out?” The E-value measurement summarizes the duration of time it takes for a mix to dry down in a controlled environment. Rather than just giving “snapshot” information on air and water porosity im-mediately after saturation as traditional physical property measures do, the goal of the E-value is to provide information on how a mix performs over time by using a single number (the higher the number the wetter the mix over time) that considers many physical property measurements…
