When you grow in coco you become a soil/hydro agnostic, LOL. Yeh, it is like a hydro medium IMO but without the air/water pumps and chillers/heaters. You can use it in a drip set up or a ebb and flow, or like me and hand water.
Some do choos to treat it more like soil, but I have found more who treat it like hydro.
