Cloning powder is favoured among commercial growers and those planning on large crops. As a powder, it has by far the longest shelf-life of any rooting product; plus, you can root a lot of clones using little powder. After you make your cut, you need to cover the tip in powder. Most growers fill a bottle cap or small cup and tap off the excess. Then, place your cutting in your medium of choice.


Cloning liquid is pretty versatile. Some growers like to dilute a few ml in 6.0pH water and immerse rooting mediums like coco coir, Jiffy pellets, or rockwool cubes in the solution to promote root zone development. More common is for growers to dunk a fresh cutting in a lid full of cloning liquid for 5 seconds, and then insert in the rooting medium.


Cloning gel is probably the most popular form of rooting hormone used by home growers these days. Again, to use gel, it’s more or less the same as the other two methods. You dunk your cutting into a small cup full of gel, only the gel is a gooey consistency and covers more of the cutting base and lower stem. Gel is easy to use and very effective. Dunk and pop your clone in a rooting cube.


Some home growers will mix cloning powder with seedling potting mix to make it more auxin-rich. This is most effective with seedlings in small pots or containers. As the plants transition to vegetative growth proper, you need to transplant to a medium with fewer auxins or stem development will be stunted.

Other growers will use a light solution to assist rooting by adding a few ml of cloning liquid with watering, directly after transplant. This is in order to promote root development without building up too many auxins in the medium that will inhibit stem growth later.


The ideal habitat for cannabis clones is a propagator under an 18-6 light schedule. Cool white CFL, MH, or LED will do just fine. Powerful lamps  are too intense and not needed. 250W is about right for any light system. Don’t be tempted to run 24 hours straight to speed things up. Clones do most of their actual rooting during the dark cycle. So stick with a conventional 18-6 cycle.

Maintaining optimal environmental conditions during propagation is critical to clone survival. Try to keep humidity 60%+ and temps at 24°C. You can occasionally mist plants with pure water if the RH gets a bit too low. Successfully rooting clones can become routine if you can control the climate and master your method.
