A rooting machine makes it much easier to root cuttings, but doing the process manually isn’t really that difficult either.
All you have to do is trim healthy cuttings (usually between 6 and 8 inches or 15 to 20 centimeters) from healthy plants.
Make sure to clip off most of the leaves, but leave the top ones intact.
Dip each cutting in rooting gel or powder and then place it in planting mix, sterile soil, rock wool, or Oasis cubes.
Ideal temperature for marijuana cloning
The ideal temperature is around 72-75*F (22-24*C). The roots should start showing up in 8-12 days.
If you aren’t rooting that many clones, you could try rooting them in water.
To maintain sterility, increase oxygen in the water, and promote rooting, create a solution of one part hydrogen peroxide (3%) with 5 parts water.
At first, provide the cuttings with 10 Watts of cool, white fluorescent light per square foot. Make sure that the clones are kept in a place with 65% humidity or higher.

Ideal humidity for marijuana cloning
You can maintain adequate humidity with a dome or cover, but remember to remove the covers after 5 or 6 days.
Still, try to keep them in high humidity even after you’ve removed the covers. Download my free grow guide for more tips about making clones and growing marijuana.
Once five days have passed, add some flowering formula fertilizer at 25% strength. Then, increase the intensity of the light to 20 Watts per square foot.
During the following ten days, increase the potency of the nutrients by adding some grow formula.
You should be able to see the roots within two weeks of the beginning.

Certain varieties will root more easily or in a much shorter time than others.
Algae can clog up clones that are growing in water. This will prevent the clones from growing adequately.
To avoid this, try using a dark-colored, opaque container to hold the water as it will deter algae growth.
Is it possible to take cuttings from a flowering plant? What about a ripe plant?
Solution: All flowering plants, including ripe ones, can be cloned. If feasible, use a cutting from a shaded area so that the bud won’t be as developed as non-shaded buds.
Stems that are woody should be avoided when choosing clones. That’s because harder stems make it harder for clones to root.
Flower offal should be trimmed thoroughly, but you should leave green leaves on the cutting.
Set the cutting in whatever medium you’ve decided to use, and keep the light as long as it’s there.
Then, the cutting will start to root and the new upper growth will be vegetative instead of just flowers.
