Root Riot® Plant Starter Cubes are pre-moistened propagation cubes made from composted and finely milled Canadian sphagnum peat moss for starting seeds and rooting cuttings in soil or hydroponic systems. This tray of 50 cubes features a pH-balanced, spongy structure that maintains an ideal air-to-water ratio to support rapid root initiation and development. Designed to hold their shape during transplanting, the cubes help reduce transplant stress while providing a consistent environment for healthy young plants. Ready to use and easily rehydrated if needed, they are suitable for a wide range of propagation applications.
