In the world of cannabis cultivation, the art of cloning cannabis stands as a powerful tool, enabling growers to replicate their prized plants effortlessly. Cloning, often referred to as “taking cuttings,” involves the creation of miniature replicas of a parent cannabis plant, each with identical genetic makeup. This technique guarantees the perpetuation of desirable traits and offers substantial yield multiplication without added expenses. This article will delve into the intricacies of cloning cannabis, shedding light on its advantages and how to start this process effectively.
A cannabis clone is essentially a genetic twin of its parent plant. They share identical genes, ensuring that they grow in a manner akin to their progenitor. This intimate knowledge of growth patterns yield potential, and potency makes cloning an invaluable asset for cannabis cultivators. The advantages of cloning extend beyond mere replication; it’s also an economically sound method. You can create numerous new plants with minimal cloning supplies in just about a week.
Cloning offers flexibility in timing as well. You can take clones at various plant life cycle stages, from the vegetative phase to a few weeks before harvest. This versatility allows you to preserve your favorite plants for future growth easily. Moreover, clones, being more mature than seedlings, exhibit faster growth in their initial weeks, making them an ideal choice for techniques like Sea of Green or 12/12 from seed as they rapidly transition to the flowering stage.
However, it’s worth noting that cloning may only suit some growers’s preferences. Some may opt for starting with seeds, appreciating the ability to cultivate multiple strains simultaneously without additional plants. Nevertheless, cloning remains an attractive proposition for those intent on preserving and multiplying specific strains.
Before embarking on your cloning journey, gather the following materials:
Mother Plant: The source from which you will take cuttings.
Sharp Scissors or Pruning Shears
Rooting Hormone (optional)
Water
Growing Medium: Options include Starter Cubes, Rockwool cubes, peat pellets, or soil.
Container for Rooting Clones: Consider using a plastic tray, humidity dome, or propagation box.
Grow Light (optional but recommended for faster growth)
Ventilation Fan (optional but recommended for air circulation)
To commence cloning cannabis successfully, meticulous preparation is key. Ensure all tools are clean and disinfected and have the necessary materials at your disposal as listed above.
Furthermore, it’s imperative to select mature cannabis plants for cloning. You can identify maturity by examining the leaf arrangement. Alternating leaves on a stem indicate readiness for cloning. A stem with alternating leaves/nodes is an ideal candidate.
To create a new clone, soak a starter cube in water briefly. There’s no need for an extended soak. Next, select a spot on the plant with fresh, top growth and new branching. Employ a sharp instrument to make a clean 45-degree cut. The optimal length for a new cutting is roughly 5-8 inches (10-20 cm).
While vigorous growth tips in the lower half of the plant are preferred for cloning, success is achievable from any part of the plant if it possesses a healthy growth tip.
Remove large lower leaves or node points and clip the top fan leaves. This step conserves energy, as excessive photosynthesis can impede root growth. Rooting hormones or cloning products can expedite root formation. Dip the cutting into rooting hormone powder or gel immediately after removing it from the water, ensuring full base coverage. Place the clone in a moistened starter cube, pressing gently to seal the rooting area.
While automatic cloners and humidity domes facilitate cloning, achieving success without these devices is possible. Following these guidelines, almost all clones can establish roots. The next section elaborates on the prerequisites for ensuring the healthy growth of your newly created clones.
To ensure the flourishing of your clones, create an environment reminiscent of the spring season—warm and humid. As clones lack root systems, they depend on moisture from their leaves. Thus, a humid cloner or frequent misting proves beneficial until roots develop. Some growers employ heating pads to maintain temperatures around 72-77 °F (22-25 °C), slightly warmer than room temperature. Grow lights can be introduced from the outset but should be programmed to run for 18 hours and off for six hours daily. This alternation between light and darkness appears conducive to rooting. Although some growers omit lights for the initial one or two days, others opt for gentle sources like CFL bulbs. Close monitoring of new clones remains essential until they establish themselves.
It’s wise to employ light sparingly during the first ten days, especially during the initial 3-4 days. While clones require light for growth, they are delicate at this stage, primarily focused on root development. Fluorescent grow lights such as CFLs and T5s, emitting low-intensity light, are ideal for clones and readily available. Maintain them at about 8-9 inches from the clones. For HID grow lights like Metal Halide and High-Pressure Sodium bulbs, maintain a distance of 2-3+ feet to prevent scorching. When using intense lights, treat cuttings like seedlings until robust roots form. If growing in Rockwool cubes or other starter cubes, transplant the clones and introduce regular light once roots emerge. Remember, new clones are delicate and require gentle handling. With patience and optimal conditions, nearly all cuttings will root successfully, some within days and others in up to two weeks or more.
