Cloning How-to

What you will need:

  • Heat Pad (preferably with thermostat)
  • Fluro Light
  • Timer (set for 18 hours, for fluro lights).
  • Propagation container with clear vented lid
  • Measuring cup
  • Spray Bottle
  • Chopstick or stick (at least 4cm long with 2mm diameter).
  • Clean towel or cloth.
  • Latex gloves.
  • Rockwool cubes (large)
  • Clone gel or powder
  • Sterile blade
  • Methylated Spirits (For cleaning of equipment).
  • Propagation solution, Canna Rhizotonic (4ml / litre of water).
  • An area with ventilation (fresh air) is recommended.
  • Clean sterile equipment is a must.

Simple Cloning Method

  1. Select a healthy young cutting with many nodes or side branches in the vegetive stage. Flowering plants may also be used, but will take longer to develop roots and there will be a higher rate of cuttings not striking roots. It is recommended to have fast growing plants for better health and yields. The cutting should be no longer than 15cm but no shorter than 5cm. The diameter of the stem at the base of the cutting should be about 2mm diameter. Larger or smaller cuttings will work, but can take longer to root.
  2. Remove cutting from mother plant with a sharp sterile blade with a diagonal cut. Place cutting into a cup with propagation solution covering the fresh cut(this will prevent air getting inside cutting). Remove the bottom side branches and leaves up to 4cm from the base of the cutting. Also some of the bigger shade leaves can either be removed or cut in half.
  3. Use chopstick or stick (at least 4cm long with 2mm diameter) and make a hole in the centre of the rockwool cube about 4cm deep. The hole should be slightly larger than the diameter of the cutting.
  4. Pre wet rockwool cubes with 50mls of the propagation solution around the area that the hole has been made. Pour some cloning gel or powder into a small container. This will prevent contaminating the unused gel, so it can be used again in the future. Dip cutting into the gel or powder, up to 4cm from the base of cutting and wipe off excess. DO NOT USE EXTRA GEL OR POWDER. A light coating works best.
  5. Gently insert cutting into rockwool cube. If the cutting does not fit snug and tight, remove a small amount of rockwool from the side of the cube and insert it in the hole.
  6. Place cuttings in propagation container on the heat pad set at 26°C. All the vent holes on the clear vented lid should be closed until roots are seen coming out of the rockwool cubes. The environment in the propagation container should be very humid. Cuttings should be sprayed with propagation solution once per day, everyday until roots appear. The clear vented lid should be dried every day to avoid moulds and rots affecting the cuttings.
  7. The cuttings can be watered about every 2 to 3 days with 30mls to 40mls of the propagation solution. Once roots are seen, half strength nutrient solution can now be applied. The vent holes can be gradually opened and then the clear vented lid removed. The whole process should take between 7 to 16 days.
