Before the lights, the nutrients, the endless watering, every grower needs to decide: are you starting from seed? Or stepping into a genetic line that already exists? That choice determines how much control you have, how much variability you invite in, and how closely you can replicate success once you find it.
What Are Clones?
A clone is a living continuation of a plant that has already proven itself. It is not a “version” of that plant. It is the same plant, carried forward through tissue.
When a cutting is taken from a cannabis plant and successfully rooted, it retains the exact genetic makeup of its “mother“. Every trait that made that plant desirable stays intact. Growth pattern, terpene expression, cannabinoid profile, resistance, yield potential. Nothing is left to chance at the genetic level. The only change is the environment. Everything else is already decided.
How Clones Are Made
Cloning cannabis is rooted in precision, even though the process itself is deceptively simple and timeless. A grower begins by selecting a mother plant that has already demonstrated consistency and quality. This plant is kept in a vegetative state.
The vegetative stage, or “veg”, in cannabis is the crucial growth phase between seedling and flowering where the plant focuses entirely on developing roots, stems, and leaves. During this stage, which typically lasts 3–16 weeks, the plant does not produce buds but builds the structural foundation necessary for high yields.
For the purpose of cloning the mother is kept in veg often for months, or even years, so it can continuously produce viable cuttings. During this process the health of the mother plant is non-negotiable! The source matters more than most people expect. A clone carries more than genetics. Any stress, deficiency, or instability will carry forward into every clone that comes from it.
Cuttings are taken from healthy branches, typically from newer growth where cellular activity is more vigorous. The stem is cut on an angle to increase surface area, then immediately placed into water or a rooting solution to prevent air embolisms from forming inside the tissue. From there, the cutting is dipped in a rooting hormone, which encourages the development of new root cells, and placed into a sterile medium such as rockwool, peat plugs, or an aeroponic cloner.
At this stage, the plant exists in a fragile in-between state. It has leaves that continue to transpire, but no roots to replace lost moisture. This is why environmental control becomes everything. High humidity reduces water loss, low-intensity light prevents stress, and stable temperatures keep metabolic processes moving without pushing the plant too hard.
Within one to two weeks, small white roots begin to emerge. Once a healthy root system establishes, the clone transitions from survival mode into active growth, ready to be transplanted and trained like any other plant.
What It Takes to Clone Successfully
A healthy, stable mother plant sets the foundation. Clean tools and sterile conditions prevent contamination at the most vulnerable stage of the plant’s life. Humidity must remain high enough to support the cutting while it develops roots, but not so high that it encourages mold or rot. Light should be gentle and consistent, supporting photosynthesis without overwhelming the plant.
Timing also matters. Transplanting too early leads to weak root systems and stalled growth. Waiting until roots are well established gives the plant a strong start once it enters its next phase.
Why Cloning Works
Cloning works because it removes one of the biggest variables in cultivation. Genetics.
When growing from seed, even within a stable cultivar, each plant expresses itself slightly differently. This is known as phenotypic variation. Some plants stretch taller, some stay compact, some lean heavily into certain terpene profiles while others express something more muted. This variability is valuable when hunting for standout plants, but it introduces unpredictability.
Clones eliminate that unpredictability. The grower is working with a known genetic expression that has already been observed and evaluated. This allows for tighter control over the cultivation process, more consistent harvests, and a clearer understanding of how environmental adjustments impact the final product. For commercial operations and serious home growers alike, this level of stable genetics is often the goal.
Where Clones Come From in Canada
Access to clones in Canada is shaped by regulation, availability, and community. Licensed producers in some provinces offer starter plants through legal retail channels, though selection is often limited and availability can be inconsistent. Micro cultivators and nurseries are beginning to fill this gap, offering more curated genetics, but access still depends heavily on provincial regulations.
Outside of formal channels, clones often move through trusted networks of growers. Shared cuts, preserved genetics, and community knowledge play a significant role in keeping certain cultivars alive and circulating. For many experienced growers, maintaining their own mother plants becomes the most reliable way to ensure ongoing access to high-quality clones.
Starting From Seed
Growing from seed introduces a completely different dynamic. Each seed represents a unique genetic combination, even when sourced from the same cultivar. This is where variation becomes an asset. Growers can observe differences in structure, aroma, potency, and resilience, selecting standout plants to keep and refine over time.
Seeds also produce a taproot, which anchors the plant deeply and can support more vigorous early growth. This foundational structure often leads to strong, resilient plants, particularly in outdoor or large-scale grows.
The trade-off is time and uncertainty. Seeds require germination, early-stage care, and, in the case of non-feminized seeds, the identification and removal of male plants. Not every seed will produce a desirable outcome. For growers interested in discovery, the process of popping seeds is part of the appeal.
The Real Difference Between Seeds and Clones
The difference between seeds and clones is not just about how a plant starts. It is about how you want to approach cultivation. Seeds introduce variation, exploration, and the possibility of finding something unexpected. They require more time, more observation, and the potential for inconsistency. If the goal is exploration, phenotype hunting, or developing something unique, seeds offer a level of genetic diversity that clones cannot.
Clones offer stability, efficiency, and replication. They allow growers to refine a process, repeat successful outcomes, and build a reliable grow using known genetics. Both approaches have value and many experienced growers move between the two, using seeds to discover and clones to preserve.
