Are you seeking the ideal starter cube for rooting plant cuttings and starting seeds? One that provides the perfect environment for root initiation and development once the clone or seed has first established roots? Look no further than Root Riot Plant Starter Cubes!


Root Riot Plant Starter Cubes are pH balanced and pre-moistened, so they are ready to use right out of the bag or in the tray. Made from Canadian peat moss, Root Riot cubes have a spongy texture that provides the ideal air to water ratio. This allows them to maintain a consistent moisture level. The texture also allows for even dry out, unlike stonewool cubes.

In short, Root Riot Plant Starter Cubes provide cuttings and seeds with the elements they need to produce healthy roots.

How To Use Root Riot

Root Riot grow plugs are supplied already moist. If they have become dry to touch, simply re-wet by placing them in a bowl of lukewarm water. The plant starter plugs should be spongy and moist – not saturated. Ideally they should be at room temperature. Unused cubes should be kept in the plastic bag to prevent drying.


  • Select cutting material – most species are best propagated from softwood tips. Prepare the material by cutting diagonally below a node or stem swelling. Remove all but a couple of leaves.
  • Dip the cut end into Clonex Rooting Gel and then place gently into the pre-formed hole in the top of the cube. Do not force the cutting in, insert it just far enough to support it.
  • Mist cuttings (Clonex Mist is recommended), and cover the tray with a clear lid or plastic bag to increase humidity. Maintain this humidity with regular misting.

  • Simply place seed into the hole of the cube.
  • Put the tray in a warm place until germination.
  • Keep an eye on the moisture in the cubes, especially in warm conditions which will speed drying out. Ideally moisture should just come to the surface when squeezed. If not, gently water the cubes and then drain well.

    When root are visible, the new plant is ready to be transplanted. Cubes can also now be transferred to any growing system.
