Update on E-Values of Sun Gro Growing

The Sun Gro'er Newsletter
The Sun Gro’er In the last issue of the Sun-Gro’er we introduced the concept of the E-value. 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…

Update on E -Values of Sun Gro Growing Media

In the last issue of the Sun Gro’er, we introduced the concept of the E-value. It was devised to help answer the common horticultural 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 immediately 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. –Todd Cavins

We have to consider mix performance, plant nutrition, water quality, logistics and cost, then choose from the hundreds of mixes available, so we can very likely meet anyone‘s needs. But sometimes recommendations come with a bit of trepidation, especially when it comes to the mix performance issue. –Todd Cavins
