Growing Media Air Filled Porosity (AFP) Testing
Вставка
- Опубліковано 13 тра 2013
- 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.
Will the height and shape of the container influence the afp of a mix or will it be consistent?
It says to put 30-40mm of water...but it looks so much more (3.03min)
