Buy cannabis clones from a licensed cultivator or retailer who can name the cultivar, describe the mother plant, and tell you when the cutting was taken. The plant should look like a healthy vegetative cannabis plant: firm stem, even green leaves, no spots, no webbing under the leaves, and white roots that hold the growing medium together. If the seller dodges questions about lineage or pest history, leave. A discounted clone that carries russet mites or hop latent viroid will cost you a whole crop.

What to look for in a clone
Clones are vegetative cuttings, so what you see is what you get. Judge the plant on structure, root development, and cleanliness, then judge the seller on records.
- Roots: white, firm, and visible at the drainage holes. Brown, slimy, or sparse roots point to overwatering or root rot.
- Stem and nodes: thick enough to stand upright, with tight internode spacing. Long, thin, stretched stems mean the mother was kept under weak light or too far from it.
- Leaf surface: flat and matte. Shiny residue, pale stippling, or fine webbing on the underside suggests mites or thrips.
- Medium: a clean plug or small pot free of algae, mold, and fungus gnat adults.
- Labeling: cultivar name, mother plant ID, rooting date, and the light cycle the plant is on.
Parameter bands that matter
- Cutting height: 4 to 8 inches is typical for a rooted clone ready for a small pot.
- Container: 2 to 4 inch cells or plugs are standard. Larger containers mean more root mass and a faster start.
- Age since cutting: 10 to 21 days for a fully rooted clone. Anything under a week is likely a fresh cutting, not a rooted plant.
- Light cycle: 18 hours on, 6 off, or 24 hours on. Keep the clone on the same cycle for the first week to limit shock.
- Root to shoot ratio: roots should match or exceed top growth. Top heavy plants with few roots stall after transplant.
- Quarantine window: 7 to 14 days in a separate space before mixing with existing plants.
Questions to ask the seller
- Which mother plant did this cutting come from, and how old is she?
- When was the cutting taken, and when did roots show?
- What pest and pathogen testing does the nursery run, and how often?
- Has this cultivar been tested for hop latent viroid?
- What light schedule and nutrient strength is the plant used to?
- What is the purchase limit and plant count rule in this state?
Pitfalls to avoid
- Buying unrooted cuttings at rooted clone prices. Unrooted cuttings need a humidity dome and skill, and they fail often.
- Taking a clone from a plant in flower without knowing it will revegetate, which takes weeks and produces odd growth.
- Mixing new clones with an established garden on day one. Pests and viroids travel with the plant, not with the soil.
- Assuming a clone is female just because the mother was. Stress can push any plant to produce male flowers.
- Moving plants across state lines. Federal law still treats cannabis as a controlled substance, and state licenses do not travel.
- Ignoring plant count limits, which cap how many clones you can legally hold at one address.
FAQ
Are clones better than seeds?
Clones give you known sex, known chemotype, and an even canopy. Seeds give you genetic variation and a taproot. Pick clones when you want repeatable results, and seeds when you want to hunt for something new.
Legal Considerations When Buying Cannabis Clones
How soon can I transplant a clone?
Once roots hold the plug together and new leaves are growing, usually 10 to 21 days after the cutting was taken. Water the plug, then move it into the final container at the same depth.
Cannabis Clones vs Seeds: Which Is Better for Your Grow?
How do I check a clone for pests?
Turn the leaves over and use a loupe on the growing tips. Look for webbing, eggs, and moving specks. Isolate the plant for a week and inspect again before it joins the garden.
Should I buy a clone that is still under a dome?
No. A rooted clone should be out of the dome and hardened off. Plants that come with condensation on the leaves have not finished acclimating and tend to wilt after transplant.
