Wyoming cannabis clone laws come down to one question: can an adult legally keep a cannabis plant at home? In Wyoming the answer is no: there is no adult-use law, no medical program, and no legal path for keeping cannabis plants at home.
This page is a plain-English guide to Wyoming 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 Wyoming.
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 Wyoming, we do not recommend ordering live clones to a Wyoming address.
Wyoming Cannabis Clone Laws: Quick Facts
| Topic | Wyoming (as of October 2026) |
|---|---|
| Adult-use status | Not legal |
| Medical program | None (only a narrow hemp-extract exception) |
| Home plants | Not allowed |
| Hemp | Licensed hemp production under the Wyoming Department of Agriculture |
Are Clones Legal in Wyoming?
A clone is a rooted cutting of a cannabis plant. Once it is in your home, it is a plant, so the Wyoming clone laws that matter are the state’s rules on cultivation and possession. Wyoming is one of the few states with neither adult-use nor a comprehensive medical program.
Adult-Use and Medical Cannabis Are Not Legal
Possession and cultivation of marijuana are offenses under the Wyoming Controlled Substances Act. Ballot efforts for medical and adult-use cannabis have not reached voters.
Hemp Is Regulated Separately
Wyoming licenses hemp production through its Department of Agriculture. Hemp licensing does not authorize keeping cannabis plants at home.
Tribal Land
The Wind River Reservation is governed by the Eastern Shoshone and Northern Arapaho tribes, which set their own rules on tribal land.
What Wyoming Clone Laws Mean for Live Plants
Federal hemp rules and Wyoming 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 Wyoming, no adult may keep a cannabis plant at home, so a live clone has no legal home there.
That is why we treat Wyoming 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 Wyoming, follow Wyoming 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 Wyoming 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 Wyoming
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 Wyoming cannabis seeds guide for how Wyoming 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 to Transplant a Cannabis Clone
Adult home cultivation is not legal in Wyoming under current law. The clone, climate and strain notes below are general reference information from our original Wyoming guide for adults 21+; they are not a recommendation to grow in Wyoming.
Read these steps as general reference; Wyoming cannabis clone laws decide whether a plant may be kept.
When ready (white roots, 5–7 days new growth):
- Pre-moisten 1-gallon pot soil
- Dig hole sized to cube
- Add mycorrhizae
- Plant cube directly
- Top level with soil
- Backfill gently
- Light water
- Reduce light 48 hours, ramp up
- Watch 7 days
Common Mistakes
- Underwatering in arid WY climate
- Burying the stem
- Cold water
- Hot light too soon
- Skipping mycorrhizae
Hardening Off for WY’s Intense Sun and Wind
Hardening off is covered here as general reference; Wyoming cannabis clone laws still decide what is allowed.
WY’s high-elevation intense UV and persistent wind make hardening off challenging:
- Days 1–2: Dappled shade, 1–2 hours, sheltered from wind
- Days 3–4: Partial sun, 3–4 hours, sheltered
- Days 5–6: Half day outside with wind protection
- Days 7–8: Full day with shade cloth
- Days 9–10: Outside overnight if lows above 55°F (which isn’t every WY night even in summer)
WY’s combination of intense UV + persistent wind + dry air is genuinely punishing. Most WY locations are at 4,000-7,000 feet elevation — UV intensity is among the highest in the country.
USDA Plant Hardiness Zones in Wyoming
These climate notes are background only; Wyoming cannabis clone laws decide whether any plant may be kept at all. For the legal side, see the Wyoming cannabis clone laws sections earlier on this page.
WY spans USDA zones 3b through 6a — among the coldest in the country, with elevation as the primary driver.
| Region | USDA Zone | Avg. Winter Low | Major Cities |
|---|---|---|---|
| – | 3b–4a | -35°F to -25°F | Yellowstone, Wind River high country |
| Cody / Northwest | 4b–5a | -20°F to -10°F | Cody, Powell, Lander |
| Laramie / Snowy Range | 4a–4b | -25°F to -15°F | Laramie, Saratoga |
| Northeast WY | 4b–5a | -20°F to -10°F | Sheridan, Gillette, Buffalo |
| Casper / Central | 4b–5a | -20°F to -10°F | Casper, Riverton, Glenrock |
| Cheyenne / Southeast | 5a–5b | -15°F to -5°F | Cheyenne, Pine Bluffs |
| Green River Basin | 4b–5a | -20°F to -10°F | Rock Springs, Green River, Evanston |
| Jackson Hole | 3b–4a | -35°F to -25°F | Jackson, Wilson |
Growing season ranges from 45 days in Jackson Hole to 140 days in southeast WY.

Best Cannabis Strains for Wyoming
Nothing in this list changes Wyoming cannabis clone laws; it is background on which cuts suit the climate.
WY’s climate filter: speed, cold tolerance, UV tolerance, wind tolerance.
Outdoor Picks (Where Season Permits)
Northern Lights — cold-climate classic, 7-9 week flower, sturdy.
Hindu Kush — landrace, fast flowering, drought-tolerant, handles wind. Genetically pre-adapted to high desert.
Critical Mass — handles cool conditions, big yields.
Frisian Dew — bred for short cool seasons.
Blueberry — cool-night performer.
Autoflowers for Short WY Seasons
Autoflowers don’t clone usefully — seed-only. 60-75 day cycles match WY’s short season better than photoperiod strains.
Indoor Statewide
WY has very cheap electricity (~10 cents/kWh, hydroelectric and natural gas advantages). Cold winters ease heat dissipation:
- GG #4 — original clone-only cut
- OG Kush cuts
- Wedding Cake, Sunset Sherbert
- Zkittlez
What to Avoid
- Long-flowering sativas (10+ weeks) — won’t finish anywhere outdoor in WY
- Heat-loving equatorial strains
- Stretchy hybrids — WY wind destroys them
Local Considerations for WY Growers
Local conditions do not change Wyoming cannabis clone laws; they only describe the growing environment.
Cold
Outdoor cultivation is genuinely difficult almost everywhere in WY. Even southern WY has 45+ day windows where overnight frost is possible.
Wind
WY is one of the windiest states in the country. Sustained 30+ mph wind is routine on the high plains. Wyoming wind would strip leaves off most strains in days.
UV
WY’s elevation creates intense UV exposure. Beneficial for trichome production but punishing on unprepared plants.
Water
WY is arid. Drip irrigation essential.
Soil
WY soils typically alkaline, low in organic matter, often rocky. Container cultivation cleanest.
Snow
WY snow can come early September in mountain areas. Outdoor harvest timing is critical.
Pests
- Grasshoppers — severe in dry years
- Spider mites — thrive in dry WY summers
- Aphids — common
- Mormon crickets — periodic outbreaks
- Wildlife — significant pressure
Wildlife
- Mule deer — significant pressure throughout
- Pronghorn — won’t typically eat plants but disrupt
- Black bears, grizzly bears — northwest WY (Yellowstone region)
- Elk — mountain areas
Hail
Summer thunderstorms with hail can destroy plants in minutes.
Indoor Cultivation in Wyoming
WY has very cheap electricity (hydroelectric + natural gas + coal infrastructure) and cold winters that ease heat dissipation. Indoor cultivation works well from a cost perspective. If/when WY ever reforms (which is a long way off), indoor would be the dominant style.
How to Check Wyoming Cannabis Laws Yourself
Summaries go out of date. Before you act on anything you read about Wyoming clone laws, including this page, check the primary sources:
- Read the current statute or regulation linked in our sources, not a news story about a bill that may not have passed.
- Check the official Wyoming agency page for any medical program rules, including plant limits if they exist.
- Look at the effective date of any new law. A bill that passed one chamber is not law.
- Ask a licensed attorney in your state if your situation is unusual, such as a move, a lease, or tribal land.
Wyoming Situations We Get Asked About
Living near Colorado or Montana
Neighboring state rules stop at the state line. Do not bring plants or cannabis into Wyoming.
Visitors to Yellowstone or Grand Teton
Federal law applies in national parks, and cannabis is illegal there.
Moving to a legal state
If you are relocating, check the new state’s plant limits and lease rules before you order anything for the new address. Our guides for Colorado and Montana are a good place to start.
Buying a gift
Every order must be placed by, and delivered to, an adult 21+ who is responsible for following the law at that address.
