These are large rockwool cubes for starting seeds and rooting cuttings in hydroponic and soilless setups. Rockwool holds water well while trapping air, which is why it is a standard propagation medium for hydro growers. They suit anyone starting seeds or cuttings for a hydro system, a drip setup or a tray. Compared with peat plugs or coco coir, rockwool holds more water and stays inert, but it must be pH-conditioned before use and it does not break down.
