Cloning Cannabis 101: An Introduction to Plant Reproduction

Cloning is a method of propagating plants that use asexual reproduction by cutting and rooting a healthy shoot. This results in clones. It is also referred to as 'taking a cutting.'

A clone has only one parent and is a genetic duplicate of that parent. Many types of plants in the wild can do this naturally through a variety of processes; for example, when a strawberry plant lays down runners, the resulting baby strawberry plants are clones of the original. Because of this natural ability, plant cloning is distinct from the controversy and ethical debate surrounding animal cloning.

MARIJUANA SEEDS >>> If you can't get a clone of a plant you like and want to grow, the next best thing is to get the right genetics by purchasing a brand-name seed from a breeder like Greenhouse, Paradise, or Royal Queen. They have kept the strain consistent and offer a pure strain to grow just like a clone.

Cloning has been used by humans for thousands of years to select plants with specific desirable properties, such as high yields or pleasant flavors. Farmers of marijuana are no exception. The donor plant is also known as a 'mother plant.' Your cloned marijuana is typically extracted from a mother plant while it is still in the vegetative stage. While they can be removed from your plant while it is flowering, the clone must revert to the 'vegging' stage, and the hormonal shift required will slow growth as the plant receives 'confusing' signals.

Why is cannabis cloned?

You can determine the gender of your plants. They share the same genes.

To the mother, i.e., select a female;

You can save money by buying seeds in bulk.

You can grow a large number of new individual plants; if you have a high-yielding, tasty, or especially potent individual plant, you can replicate it.

Although we recommend spending as much money as possible on good seeds from a reputable company elsewhere on this site, this is only to get you started. You can be self-sufficient for cuttings with a well-designed grow room programmed, growing only the highest quality weed from cuttings that you have selected yourself. Because they are genetically identical, all new smoke will taste the same as the last (given the same nuts).

How to Cut a Marijuana Leaf

Taking a cut is the first step in cloning your plants. Although taking a cutting from a flowering plant is possible, we recommend against it. Once your plants have finished flowering, let them do their thing: grow high-quality weeds for you.

As the donor, select a healthy plant with at least six nodes or that is at least four weeks old. Young pre-flowering plants can be cut for cuttings. Once you've decided on a phenotype and are certain of its sex, keep it growing under 18-20 hours of light to prevent it from entering the flowering cycle. This will be your mother plant, and if cared for properly, she will provide you with an almost infinite supply of cuttings. Some growers take cuttings from all of their plants (before flowering) on a regular basis, especially if they are starting a batch of plants from seed. These cuttings are clearly labeled to match the parent plants. When the parent plants are finished, the best one can be chosen, and the appropriate clone can be selected. Your next generation of young plants will be exact replicas of your favorite adult.

A clean, sharp razor blade, scalpel, or sharp scissors are required for cutting. Using rubbing alcohol, sterilize the cutting edge.

Make a 45-degree angle cut, i.e., on the 45. Choose a low-growing green branch with two or three nodes (not a fan leaf). Avoid using woody branches. Cut the branch at a diagonal angle about 14 inches (5-10mm) below a node with the razor.

Rooting your cutting

Low light to encourage rooting More is not better because the clone will not add leaf mass or perform significant photosynthesis. The light essentially causes certain hormones to be released.

A structure of support

Moisture near the roots

To keep the leaves from drying out, keep the humidity high.

To make a single clone, place your cutting in a Dixie cup with several inches of water and cover it with a plastic baggie to retain moisture. Every three days, change the water. Marijuana clones will take 6 to 14 days to root. White bumps will appear on the lower part of the stem submerged in water just before the roots appear (if that is the method you are using). Some gardeners transplant when the roots are one inch long, while others wait until the roots are six inches long. We prefer to wait until they are at least 3" long. Longer roots take longer to develop but result in less shock when transplanted.

Rooting marijuana with a gel or powder

Although cuttings can be rooted in water, it is preferable to use a rooting gel or powder. Remove the bottom leaves of the cutting and soak them in the rooting compound before planting them in your preferred growing medium. Rockwool cubes work especially well. The cutting is extremely fragile at this point. It should not be forced into the growing medium. Make a hole with a pencil and gently insert the cutting, closing the hole with your fingertips. If you take the cutting just above a node on the plant, the branch will split in half as if you had pinched it.

This way, your mother plant will produce an exponential number of cuttings, ensuring that you are never short of babies for your nursery. Give your cuttings a drink of water and a mist from a water sprayer once they're all ready and in their pots. Make certain that no light can reach the roots. If you have several cuttings, place them in a propagation tray with a plastic lid to help limit transpiration and ensure that the plant retains plenty of water. Remember that the young clone has no roots at this stage and must absorb water through the leaves and cut stem.

The young plants will require light, but in their vulnerable state, it is critical not to burn them with hot lights. Begin by placing a fluorescent light or full spectrum LED grow light about 10 inches (25cm) away and gradually moving it closer as the plant grows. If you don't have enough room for a separate nursery, place the young plants in the grow room, partially shaded by the mother plant's leaves.
