Coco and buffering

Coco substrate can act as a buffer, storing water and nutrients for the plant. Buffering can work in several ways. There are water buffers, pH buffers, nutrient buffers and the coco buffer. What are the differences? Here you can see one example. Discover the other differences by watching our video!

Nutrient buffer

Peat/mineral soil: nutrients bind to the fibres or particles using charged sites know as Cation Exchange Sites. Nutrients are then released into the solution around fibres in the soil (slow release/equilibrium).

Coco: fibres are already filled with potassium and sodium.
