Run four checks before you pay for a cannabis clone: squeeze the stem, turn over every leaf, look at the root mass, and read the label for cultivar, mother plant, and pathogen testing. A healthy cutting passes all four. A cutting that fails one check is a delivery system for mites, powdery mildew, or hop latent viroid, and the cost of treating an infected room runs many times the price of a better clone.

What to look for at the counter
Stem and node structure
A healthy clone stands on its own. The stem should feel firm between your fingers, not hollow or soft at the base. Look for three to five nodes on a plant roughly 4 to 8 inches tall. Short internode spacing points to good light management at the nursery. A stretched, thin stem with wide gaps means the cutting was kept under weak light and will need support after transplant.
Legal Considerations Buying Cannabis Clones
Reject any clone with a dark, pinched, or water-soaked stem base. That is damping off, a fungal collapse that rarely reverses. Also reject plants already flowering or showing single-blade leaves and rounded tips. Those are signs a cutting was taken from a mother in bloom, which forces the plant through a revegetation cycle that can add weeks before normal growth resumes.
Cannabis Clones vs Seeds: Which Is Better for Your Grow?
Leaves, top and bottom
New growth at the top should be a clean, even green. Lower leaves may yellow slightly on a rooted cutting, which is normal as the plant mobilizes nutrients for roots. Yellowing that reaches the middle of the plant, brown leaf edges, or a purple cast on the leaf stems points to a nutrient or root problem.
Cannabis Clone Buying Guide: Price, Provenance, and Pitfalls
Turn each pot upside down and inspect the underside of the leaves along the veins. You are looking for three things:
- Fine webbing or tiny moving specks, which indicate spider mites
- Silver or bronze stippling, which is mite feeding damage
- White powdery patches or a gray fuzz, which indicate mildew or botrytis
Also check the growing tip for distorted, crinkled, or variegated leaves. Twisted new growth can signal a viroid, a pH swing, or broad mite damage, and none of those are worth bringing home.
Roots and media
If the clone is sold as rooted, slide the plug partway out of the pot or ask staff to show you. Healthy roots are white to cream, firm, and branching. Four to eight visible roots at the edge of a rockwool cube or peat plug is a good sign. Brown, translucent, or slimy roots mean root rot. A plug that drips when squeezed is overwatered and a poor bet.
Smell the media. Earthy is fine. Sour, sulfur, or ammonia smells point to anaerobic conditions. Green algae on the surface is cosmetic, but fuzzy white mold on the cube is not.
Labels and pathogen testing
A serious seller can name the cultivar, the mother plant, the date the cutting was taken, and any lab test performed on the mother. Ask directly whether the stock is tested for hop latent viroid. HpLVd spreads through contaminated blades and shared plant material, and infected plants often look normal for a full cycle while yielding less and producing weaker flowers. Visual inspection cannot rule it out. A nursery that tests and can show results is worth a premium over one that cannot.
Confirm the plant is female and came from a female mother. Clones from seed-grown plants should be sexed before sale.
Numbers to check before you commit
- Height at sale: 4 to 8 inches with 3 to 5 nodes
- Stem: firm enough to stand without a stake
- Visible roots on a rooted clone: 4 to 8, white to cream
- Media moisture: damp, not dripping
- Runoff pH: 5.8 to 6.2 for rockwool and coco
- Feed strength at handoff: EC 0.6 to 1.2
- Acclimation light: 150 to 300 PPFD for the first week
- Acclimation temperature: 65 to 75 F
- Acclimation humidity: 60 to 70 percent
Pitfalls that cost the most
- Unrooted cuttings sold as rooted. A cutting with a callus but no roots needs a humidity dome and another week or two. That is fine if you know, and a problem if you paid rooted prices.
- No quarantine. Keep new clones apart from the main garden for 10 to 14 days. Inspect leaf undersides twice in that window.
- Trusting a name. "Elite cut" and "original genetics" are marketing words. Ask for provenance and a test result, not a story.
- Buying from a flowering room. Clones taken from flowering mothers revegetate slowly and grow unevenly.
- Ignoring the media. Saturated plugs and reused trays carry root pathogens straight into your pots.
- Skipping the viroid question. HpLVd is the hardest problem to spot by eye and the easiest to bring home on a clean-looking plant.
FAQ
How do I check a clone for spider mites in the store?
Tap the stem over a white sheet of paper. Mites and their cast skins show as moving pepper flakes. Then look at leaf undersides near the veins with a phone light for webbing and stippling. If you see any, do not buy from that tray.
Is a yellow lower leaf a deal breaker?
Not on its own. One or two faded lower leaves on a rooted cutting are normal. Yellowing across the middle and top of the plant, brown edges, or soft stems are reasons to pass.
Should I buy rooted or unrooted clones?
Rooted clones cost more and carry less risk for a new grower. Unrooted cuttings work if you have a dome, a clean tray, and a week to spare. Either way, inspect the cut end for rot and confirm the cutting date.
How long should I quarantine a new clone?
Ten to 14 days in a separate space with its own tools. Watch for mites, mildew, and unusual leaf distortion before it joins the main room.
Can a clone look healthy and still carry hop latent viroid?
Yes. Many infected plants show no clear symptoms for a full cycle. Testing the mother plant is the only reliable screen, so ask for results before you buy.
When should I transplant?
When roots reach the edge of the plug and the plant has recovered from transport, often a few days after purchase. Move it into a pot sized for its root mass and keep the first week of light below 300 PPFD.
