A cannabis clone is a rooted cutting from a mother plant, so it carries the same genes as its parent. To buy one, inspect the root ball, ask about pest and disease history, confirm the THC or CBD level, and check that clones are legal in your state. Healthy clones have white roots, firm stems, and leaves with no spots, webbing, or powdery film.
What Is a Cannabis Clone?
A clone is a plant grown from a cutting instead of a seed. The grower takes a branch from a mother plant, dips the cut end in rooting hormone, and places it in a medium such as rockwool, peat, or coco.
Once roots form, the cutting becomes a new plant with the same traits as the mother. Same flavor, same cannabinoid profile, same flowering time. That consistency is the main reason growers buy clones rather than start from seed.
Hemp Clones vs Marijuana Clones: Which Can You Buy?
Federal law defines hemp as Cannabis sativa with 0.3 percent delta-9 THC or less on a dry weight basis. Clones cut from hemp mother plants fall under that definition, and they are legal to sell and ship under the 2018 Farm Bill.
Clones from high-THC marijuana plants remain illegal at the federal level. State rules run from full legal markets to outright bans, so check your state agriculture department before you pay for anything.
For CBD buyers, this matters. A hemp clone should arrive with paperwork that shows THC content and a license number from the nursery.
What to Inspect Before You Buy
Roots
Ask for a photo of the root ball or look at it in person. Roots should be white or light tan and fill the plug without spiraling around the edge.
Brown, slimy, or sparse roots point to root rot or a cutting that never rooted. Skip those plants.
Stems and Leaves
A healthy clone stands on its own and holds its leaves out. Yellow lower leaves, purple stems, or curling tips can signal cold stress, hunger, or a pest problem.
Pests and Mold
- Check the undersides of leaves for mites, eggs, and whitefly.
- Look for webbing between stems.
- Smell the plug. A sour or musty odor can mean mold.
- Ask what the nursery uses for IPM (integrated pest management).
Questions to Ask the Seller
- What is the THC and CBD content of the mother plant, and do you have lab results?
- How old is this clone, and how long has it been rooted?
- What medium is it in, and what nutrients has it received?
- Has this batch shown any pests or disease in the last 30 days?
- Do you provide a license number and a bill of lading?
- What is your policy if the plant arrives dead?
A seller who answers all six without pause is worth your money. Vague answers about genetics or testing are a warning sign.
Why Lab Tests Matter for CBD Clones
Hemp testing rules vary by state, but the number that matters is total delta-9 THC. A clone that tests hot (above 0.3 percent) can put your crop out of compliance, and in some states that means the plants must be destroyed.
Ask for a certificate of analysis (COA) from an ISO 17025 lab. Read the sample date, the batch number, and the THC column, not just the CBD number.
How to Vet a Clone Nursery
- Confirm the nursery holds a current hemp license in its state.
- Ask how mothers are kept and how often they are replaced.
- Request a COA for the mother plant, not only for finished flower.
- Check reviews from growers in your climate, since shipping stress shows up fast.
A nursery that tracks mother plants and keeps clean records will hand over that proof. If a seller dodges the question, buy elsewhere.
How Clones Ship
Most nurseries ship rooted clones in labeled trays with a moist plug and a breathable sleeve. Plants travel overnight or in two days, and heat or cold packs go in the box depending on the season.
Moving hemp clones across state lines can require a phytosanitary certificate and a permit. Confirm the paperwork before you order.
The First 48 Hours After Delivery
- Open the box and check each plant for damage, pests, and moisture.
- Water the plug if it feels dry, but do not soak it.
- Place the clones in indirect light at room temperature for a day.
- Check for mites or eggs before you move them near other plants.
- Hold off on transplanting for a few days so they can adjust.
- Quarantine new clones away from your main grow for 7 to 14 days.
Quarantine is the step most growers skip and the one that costs the most. One infested clone can spread mites through a whole room.
What Do Cannabis Clones Cost?
Price depends on strain, quantity, and how much testing the seller provides. Single clones from a licensed nursery cost more per plant than a tray of 50, and rare genetics carry a premium.
Watch for deals that look too good. Cheap clones often come from unverified mothers, and you have no way to confirm the cannabinoid profile until you test the finished flower.
Mistakes That Kill Clones
- Planting into hot soil or a full-strength nutrient mix too soon.
- Leaving clones in direct sun before roots fill the plug.
- Skipping quarantine and mixing new plants with old ones.
- Buying without a COA or a license number.
- Ordering in extreme heat or cold without asking about shipping packs.
FAQ
Are clones female?
A cutting carries the same genes as its mother, so a clone from a female plant is female. Buy from a nursery that keeps mothers in a controlled room and confirms sex before taking cuttings.
Can I buy cannabis clones online?
Yes, for hemp. Licensed hemp nurseries sell and ship clones to states that allow it, with lab paperwork attached. Marijuana clones cannot cross state lines under federal law.
How long until a clone is ready to flower?
A rooted clone needs two to four weeks of vegetative growth before it can support flowers. Growers often flip to a 12/12 light cycle once the plant has a strong root mass and several new nodes.
Should I buy seeds or clones?
Clones give you the exact plant you already liked. Seeds give you genetic variety and a lower risk of passing pests from a nursery into your garden.
