HDI Root Riot Replacement Cubes are premium propagation cubes designed to deliver faster rooting, stronger starts, and higher success rates for cuttings and seedlings.

Why Growers Choose Root Riot Cubes

Fast, aggressive root growth
Each cube is pre-charged with gentle organic nutrients and beneficial compounds that stimulate quick root initiation and healthy development.

Perfect air-to-water ratio
The spongy texture holds moisture evenly while allowing ample oxygen to reach young roots—reducing damping-off and root rot.

pH balanced & ready to use
No soaking, buffering, or preparation required. Simply insert your cutting or seed and go.

Cleaner, easier handling
Unlike rockwool, Root Riot cubes do not produce irritating fibers or dust, making them safer and easier to work with.
