Washington Cannabis Clone Laws: What Adults 21+ Should Know

Washington cannabis clone laws come down to one question: can an adult legally keep a cannabis plant at home? In Washington the answer surprises people: adult-use cannabis is legal, but adults still may not keep plants at home. Only qualifying medical patients can.

This page is a plain-English guide to Washington cannabis clone laws. It covers what state law says about plants, any medical program, and how federal hemp rules fit in. It is information, not an offer to sell live plants into Washington.

Before you read on: Seeds Here Now sells only to adults 21 and older. Nothing here is legal advice. Because adult home cultivation is not legal in Washington, we do not recommend ordering live clones to a Washington address.

Washington Cannabis Clone Laws: Quick Facts

Topic	Washington (as of October 2026)
Adult-use status	Legal for adults 21+ since Initiative 502 (2012)

Regulator	Washington State Liquor and Cannabis Board (LCB)

Are Clones Legal in Washington?

A clone is a rooted cutting of a cannabis plant. Once it is in your home, it is a plant, so the Washington clone laws that matter are the state’s rules on cultivation and possession. Washington is one of only a few adult-use states that do not allow adults to keep plants at home.

Adult-Use Sales, but No Adult Home Plants

Voters approved Initiative 502 in 2012, and licensed stores have sold cannabis to adults since 2014. The law did not include home cultivation for adults. Bills to change that, including SB 6204 and HB 1449 in 2026, stalled in committee.

Medical Patients

Qualifying patients with a valid authorization may keep a limited number of plants, with higher limits for patients entered in the state’s medical cannabis authorization database. The Department of Health publishes the current rules.

Possession Limits

Adults 21+ may possess up to 1 ounce of flower and set amounts of concentrates and infused products bought from licensed stores.

What Washington Clone Laws Mean for Live Plants

Federal hemp rules and Washington cannabis laws are separate systems. A cutting can be sold as hemp-compliant under federal law, and state law still decides whether an adult may keep a cannabis plant at home. In Washington, adults may not keep cannabis plants at home even though stores are legal. Qualifying medical patients are the exception, under Department of Health rules.

That is why we treat Washington as an information-only state for clones. If you are moving to a state where adults can keep plants, read that state’s guide first. If you live in Washington, follow Washington cannabis laws as they stand today, not as they might change.

Federal Hemp Rules: What the Seed Change Means for Clones

Our clones ship as hemp-compliant cuttings under the federal hemp definition in effect today. You may have read about upcoming federal changes to hemp and seed rules. As we understand them, those changes are aimed at seeds, and live clones are not affected by the seed change.

That federal point does not change Washington law. Federal and state rules can both change, and nothing on this page is a promise about future law. For official background on the federal hemp definition, see the Congressional Research Service summary in our sources.

Cannabis Seeds and Washington

Seeds Here Now has been a US, breeder-direct seed bank since 2010, run by James Bean. Our seeds are sold only to adults 21+, in sealed breeder packs that name the breeder and lineage. See our Washington cannabis seeds guide for how Washington cannabis laws treat seeds.

Buyers are responsible for following the laws where they live.

Where Clone-Only Cuts Come From

Some famous plants, such as the Gorilla Glue #4 cut, exist only as clones taken from plants that descend from one original mother. That history is why growers talk about named cuts, and why clone sellers list the source of every mother plant.

If you are researching a cut by name, our clone FAQ explains how we describe lineage and aroma. We do not make claims about effects.

Hop Latent Viroid (HpLVd)

Hop latent viroid is a common pathogen in commercial cannabis and a fair question to ask any clone seller. Ask for current testing paperwork for a specific cut rather than relying on a general label.

How Cannabis Clones Are Made

Adult home cultivation is not legal in Washington under current law. The clone, climate and strain notes below are general reference information from our original Washington guide for adults 21+; they are not a recommendation to grow in Washington.

How a cut is made is a separate question from Washington cannabis clone laws, which cover whether it may be kept.

Mother Plant Provenance — Pacific NW History

WA and OR’s long cannabis history produced legitimate clone-only cuts: original Bubba Kush, multiple OG Kush lineages, Dutch Treat, and others have Pacific Northwest roots. Provenance matters in WA because actual cloning-cannabis-plants-a-complete-guide/”>mother plant pedigree is documented and traceable through generations of Pacific NW growers.

How to Transplant a Cannabis Clone

Read these steps as general reference; Washington cannabis clone laws decide whether a plant may be kept.

When ready (white roots, 5–7 days new growth):

1. Pre-moisten 1-gallon pot soil
2. Dig hole sized to cube
3. Add mycorrhizae
4. Plant cube directly
5. Top level with soil
6. Backfill gently
7. Light water
8. Reduce light 48 hours, ramp up over a week
9. Watch 7 days

Common Mistakes

• Overwatering (especially in damp western WA)
• Burying the stem
• Cold water
• Hot light too soon
• Skipping mycorrhizae

Hardening Off for WA Outdoor

Hardening off is covered here as general reference; Washington cannabis clone laws still decide what is allowed.

Standard 10-day acclimation. Western WA’s mild damp climate is gentle; eastern WA’s intense sun + dry heat require more shade in early days.

• Days 1–2: Dappled shade, 1–2 hours
• Days 3–4: Partial sun, 3–4 hours
• Days 5–6: Half day outside
• Days 7–8: Full day, in overnight if below 50°F
• Days 9–10: Outside overnight if lows above 55°F

Hop Latent Viroid (HpLVd)

The most economically devastating cannabis pathogen of the past decade. WA’s commercial industry has actively fought HpLVd. We use HpLVd-screened mother stock. Tissue culture lines available.

Best Cannabis Strains for Washington

Nothing in this list changes Washington cannabis clone laws; it is background on which cuts suit the climate.

Western WA / Puget Sound (Cool Damp)

Frisian Dew — bred for damp climates similar to Puget Sound. Develops purple.

Blue Dream — Pacific NW classic, mold-resistant.

Northern Lights — fast flowering for cool falls.

Durban Poison — mold-resistant landrace.

Critical Mass — handles humidity.

Eastern WA / Yakima Valley (Hot Dry)

OG Kush clone-only cuts (Larry, Tahoe, SFV) — handle dry heat.

Sour Diesel — finishes well, big yields.

Blue Dream — versatile.

Gorilla Glue #4 — clone-only, thrives in long warm seasons.

Durban Poison — heat-tolerant.

Mountain Valleys

Autoflowers from seed or indoor. Photoperiod risky outdoor above 2,000 feet.

Indoor Statewide

WA has cheap electricity (~10 cents/kWh, among the lowest nationally — hydroelectric advantage).

• GG #4 — original clone-only cut
• OG Kush cuts with Pacific NW provenance
• Wedding Cake, Sunset Sherbert, Triangle Kush
• Zkittlez
• Bubba Kush — Pacific NW clone-only

What to Avoid

• Mold-susceptible strains in Puget Sound late summer

Local Considerations for WA Growers

Local conditions do not change Washington cannabis clone laws; they only describe the growing environment.

Climate Variation

WA has more growing zones than most states. Strain selection must match region. A Seattle-perfect strain might fail in Spokane. A Yakima Valley setup is irrelevant to Forks.

Humidity (Western WA)

Late-summer Puget Sound humidity drives mold pressure. Strain selection critical.

Drought (Eastern WA)

Drip irrigation essential in eastern WA. Hard water in many areas.

Soil

WA soils vary widely — sandy on coast, volcanic in Cascades, deep loess in Palouse (excellent for cultivation), alkaline in eastern Columbia Basin. Container cultivation cleanest for variability avoidance.

Pests

• Spider mites — common
• Aphids — spring and summer
• Powdery mildew — western WA humidity
• Botrytis — bud rot in flower stage western WA
• Spotted lanternflies — emerging threat

Wildlife

• Black-tailed deer — western WA
• Mule deer — eastern WA
• Black bears — Cascade range and coastal mountains
• Elk — Olympic Peninsula and Cascades

Wildfire Smoke

Increasing concern across WA. Late-summer wildfire smoke degrades outdoor harvests. The 2020 fires affected substantial outdoor cultivation. Indoor is insulated from this risk.

Rain Timing (Western WA)

Western WA’s rainy season begins in October, ramping up through fall. Strain selection to finish before mid-October avoids late-season rain pressure.

Cheap Hydroelectricity

WA’s hydroelectric infrastructure makes electricity among the cheapest in the country. Indoor cultivation costs are dramatically lower than in coastal states or the Northeast.

Indoor Cultivation in Washington

WA has the cheapest electricity of any major state (~10 cents/kWh thanks to Columbia River hydroelectric). Cold winters ease heat dissipation. WA has built sophisticated indoor cultivation infrastructure — Seattle’s tech industry and Spokane’s cheaper real estate both support sophisticated grow setups.
