Cannabis Seeds for Wyoming Growers

Yes. Cannabis seeds are legally classified as hemp under the 2018 Farm Bill. The seed itself contains no meaningful THC regardless of what the plant would eventually produce, so purchasing seeds — including high-THC feminized varieties — is legal in Wyoming. Triangle Seeds ships cannabis seeds directly to Wyoming customers.

Yes. Triangle Seeds ships cannabis seeds to Wyoming home growers. Orders are packaged discreetly and typically go out within 1-2 business days. Questions about your order? Text or call us M-F, 10-6 EST at (919) 410-6945.

Cannabis plants are either male or female. Only female plants produce the buds (flowers) you're growing for. Feminized seeds are bred to produce female plants almost exclusively, so you're not wasting space, time, or resources on males that need to be removed. All of the seeds we sell are feminized.

Photoperiod varieties flower in response to a change in light schedule. Outdoors, they begin flowering as days shorten in late summer. Indoors, you trigger flowering by switching to a 12-hours-on/12-hours-off schedule. They give more control over plant size and yield but take longer to finish.

Autoflower varieties flower automatically based on age, finishing 9-12 weeks from seed regardless of light schedule. For Wyoming's short outdoor growing season — often under 100 frost-free days across much of the state — autoflowers are not just a preference but essentially the only practical choice for outdoor hemp production. They allow licensed growers to plant in late May or early June and harvest well before fall frosts arrive. Not sure which is right for you? See our Strain Selection Guide.

CBD (cannabidiol) is a non-psychoactive compound found naturally in the cannabis plant, commonly reported as calming and supportive for sleep, stress, and everyday discomfort — without the high associated with THC. CBD seeds are the primary variety grown commercially under Wyoming's WDA hemp licensing program. Wyoming's short outdoor season and variable mountain climate require variety selection focused on early finish times. Home growers can purchase seeds now to be ready if Wyoming legalizes cultivation. Browse our CBD seeds or use the Strain Selection Guide to find the right variety.

No. Cannabis cultivation is a felony in Wyoming at any scale — and notably, it bypasses the misdemeanor tier entirely. Simple possession of three ounces or less is a misdemeanor (up to 12 months in jail, $1,000 fine), but growing even a single plant for personal use jumps directly to a felony. There is no medical cannabis program, no decriminalization, and no personal use exception. Even Cheyenne's city council rejected a local decriminalization proposal by a 6-3 vote in March 2023. Many Wyoming residents are purchasing seeds now to be ready if and when that changes. Read the full Wyoming home grow law breakdown.

No. Wyoming has no medical cannabis program as of 2026. The only cannabis-related patient access is a narrow 2015 law — HB 32 — that allows patients with intractable epilepsy to possess and use hemp extract containing no more than 0.3% THC and at least 5% CBD, with a physician's recommendation. There is no dispensary or in-state supply chain supporting this access. No medical cannabis bill has advanced to a floor vote in the legislature. Wyoming is bordered to the south by Colorado (adult-use since 2012) and to the north by Montana (adult-use since 2020).

No meaningful progress has been made in the 2023, 2024, 2025, or 2026 legislative sessions. Medical cannabis and decriminalization bills have been introduced but have not advanced to floor votes. A 2024 budget session decriminalization bill (HB 204) did not receive the two-thirds majority needed to pass in the short session. No comparable bill moved in 2025 or 2026. Wyoming also has no citizen initiative process, so voters cannot place cannabis reform directly on the ballot. A 2025 statewide survey found approximately 65% of Wyoming respondents support legalizing recreational marijuana, but that has not translated into legislative action.

Yes, with a Hemp Producer License from the Wyoming Department of Agriculture (WDA). Unlike many states that have shifted to the USDA federal program, Wyoming maintains its own state-level hemp licensing program. Applications are submitted through the WDA Agriculture Licensing website at agriculture.wy.gov/hemp-program. The 2026 application deadline was March 9, 2026 at 5:00 PM and has passed — the next window opens in early 2027. Once licensed, growers are subject to random audits by WDA, which inspects approximately 10% of all licensees annually. Wyoming law preempts any municipality from restricting licensed hemp cultivation on private property. See the full Wyoming hemp licensing walkthrough for details.

The application fee is $750 for individuals and businesses, or $500 for non-profit organizations and educational institutions — both non-refundable. Wyoming's $750 fee is on the higher end compared to most states in this series. Additional costs include pre-harvest THC testing fees paid directly to WDA Analytical Services Lab (contact the lab at 307-742-2984 for current pricing), and any GPS amendment fees if registered site coordinates need to be changed after approval. Licenses expire December 31 and must be renewed annually.

Wyoming spans USDA zones 3a through 6b, with most of the state in zones 3b through 5b. The high plains and basin areas of central and eastern Wyoming fall in zones 4b and 5a. The Big Horn Basin and areas around Casper reach zones 5b and 6a — the warmest growing conditions in the state. The outdoor growing season runs roughly late May through early September in most of the state, often under 100 frost-free days. Late-maturing photoperiod varieties that finish in October are not a practical outdoor choice for most of Wyoming. Autoflowering varieties that finish in 9-12 weeks are the only reliable outdoor option for most of the state. In the warmer Big Horn Basin and lower-elevation areas, short-season photoperiod strains may work with careful timing. Enter your zip code on our zone map for your specific window, then browse our autoflowering varieties, short-season varieties, or CBD seeds.

Across most of Wyoming (zones 4b-5b), last frost typically falls between late May and early June. Start seeds indoors in early to mid-May and transplant outdoors once frost risk has passed — typically late May to early June. Autoflowers started in late May will finish in late July to mid-August, well ahead of early fall frosts that can arrive in September at higher elevations. In the warmest areas including the Big Horn Basin (zones 5b-6a), a mid-May transplant is feasible with short-season strains potentially finishing in early October. Plan your WDA license application carefully — the window closes in early March, well before spring planting.
