Not just for hydro...Coco coir is a hydro medium made up of ground coconut husks.
I mix it with my soil for better aeration. It also helps regulate moisture, giving some when plants need it, and absorbing excess when watering soil too much.
It has no nutritional or pH value(neutral pH), so it needs to be mixed with nute-rich soil or plants within it need to be fed/watered more frequently.
