• Rooting up to 10 days sooner

• 30% longer roots

• Up to 156% more roots


Root Riot Plant Starter Cubes

Root Riots are ideal for rooting plant cuttings. They have a great spongy texture which retains the perfect air/water ratio for healthy, rapid root growth. These cubes are specially inoculated with micro nutrients and biologically active ingredients. This gives your young cutting a slight nutrient charge that nourishes young plants and aids in root development. 




Root clonex resizeCLONEX® Mist is easy to use and generates quicker, more vigorous and healthy clones. For best results use with CLONEX® Rooting Gel and Root Riot®propagation cubes. All your cuttings benefit from housing them in a propagator with adjustable ventilation.



Instructions for use – Softwood and Semi-Hardwood cuttings


  • prop clonex mist spraySelect young growing shoots from your healthiest plants.  If possible the growing tips can be sprayed with Clonex® Mist once or twice in the week before cuttings are taken. Cut off shoot tips (1), each with four or five pairs of leaves, and remove the two lower pairs of leaves



  • prop cuttingAlways use a clean sharp knife or blade. Make a clean diagonal cut across the base of the cutting just below the lowest leaf node.


  • prop dip clonex

    Pour a small amount of Clonex into a separate container for immediate use. Do not dip cut tissue into the original container, and do not return any unused Clonex as this might contaminate the remaining gel.




  • prop in rootriotImmediately dip the cutting into Clonex (2), about 15 mm, then insert the cutting into the propagation medium (3) just deep enough to support  the cutting.




  • prop clonex mist spraySpray the new cuttings with Clonex® Mist and place in a propagator. The lid should be down and the vents closed.
  • After 2-3 days spray the cuttings with Clonex® Mist again and open the vents slightly.


Check the new roots after a few days – continue mist until the plant is established following potting up. If planting in soil, place soil carefully around the roots to avoid damaging them

TOP TIP: The new cuttings should be kept in a covered propagator, and most plant species will thrive with propagation temperatures between 21-24C with the humidity around 90%.  After new roots appear your plant will need to be hardened off. Open the propagator slightly to allow a small amount of air in.  Increase the amount of opening each day and finally remove the cover completely.  When the young plants are growing strongly they can be placed into the larger Rockwool cubes or potted into soil or coco. Place soil carefully around new roots to avoid damaging them.
