  • Plant roots require air as well as water to remain healthy. The amount of air held within a growing media is referred to as Air filled porosity or AFP . Testing procedures for AFP aren't difficult and can be done at minimal cost with simple equipment built from readily available materials and a little bit of time. This video shows a process for carrying out a practical on-site air filled porosity test on growing media.
