Jongkind Grond Hydro Substrate granules are also suitable for various applications such as pot plant cultivation where a layer on top of media shields from algae, pests, heat and light. A bottom layer can be added for increased drainage and to prevent plants standing in water. When making custom soil mixes it is ideally used as a 50:50 mix with coco coir or composts.
Jongkind Hydro can be used alone for hydroponic substrate cultivation, its high C.E.C buffers any changes and its irregular shape helps root development and stops large interstitual spaces. Before use it is often best washed to remove dust, and then soaked in quater/half strength nutrient solution.
