Cannabis Seeds for Washington Growers

Yes. Cannabis seeds are federally legal hemp products under the 2018 Farm Bill and can be purchased and shipped to all 50 states including Washington. Triangle Seeds ships seeds directly to Washington customers. Note that home cultivation in Washington requires a valid medical cannabis authorization — recreational home growing is not currently permitted under state law.

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 naturally as days shorten in late summer. Indoors, you trigger flowering by switching to a 12-hours-on/12-hours-off schedule. They typically take longer to finish but give more control over plant size and yield.

Autoflower varieties flower automatically based on age, usually finishing 9-12 weeks from seed regardless of light schedule. Washington's west side climate — cool, cloudy, and often damp — creates mold pressure that makes faster-finishing autoflowers an appealing outdoor option. Eastern Washington's warmer, drier climate is more forgiving for full-season photoperiod varieties. Not sure which is right for you? See our Strain Selection Guide.

CBD (cannabidiol) and CBG (cannabigerol) are non-psychoactive compounds found naturally in the cannabis plant. People commonly report CBD as calming and supportive for sleep, stress, and everyday discomfort. CBG is often described as more clarifying, associated with focus and a lighter sense of ease. Both are widely used as alternatives to pharmaceutical options for mild anxiety, inflammation, and pain.

Many growers find that blending CBD or CBG varieties with THC varieties produces a more balanced experience. Growing your own gives you direct control over what goes into your plants. Check out our Strain Selection Guide to explore our hemp varieties.

No. Washington is the only recreational-legal state where home cultivation without a medical authorization is a Class C felony, carrying up to five years in prison and up to $10,000 in fines. Recreational cannabis has been legal since 2012, but home growing rights were not included in the original initiative and eleven consecutive years of legislation have not yet changed the law. Medical patients with a valid authorization under RCW 69.51A may grow at home. Read the full Washington home grow law breakdown for details.

Non-registered patients with a written authorization may grow up to four plants. Registered patients who voluntarily enter the Washington State Medical Cannabis Authorization Database may grow up to six plants — or up to fifteen with specific provider authorization. No housing unit may have more than fifteen plants total regardless of how many patients live there. Registration is voluntary but provides higher plant limits, stronger legal protections, and tax-exempt purchasing at cannabis retailers. Read the full Washington home grow law breakdown for details.

Qualifying conditions under RCW 69.51A.010 include cancer, HIV/AIDS, multiple sclerosis, epilepsy and other seizure disorders, Crohn's disease, PTSD, Hepatitis C, Tourette's syndrome, traumatic brain injury, and other terminal or debilitating conditions. A licensed Washington healthcare provider — physician, physician assistant, ARNP, naturopathic physician, or osteopathic physician — must certify your condition and that you would benefit from medical cannabis.

Advocates are persistent. Senate Bill 6204 advanced further than any previous attempt in the 2026 session, passing out of committee before stalling in the Senate Rules X file. The same bill or a successor is expected to return in the 2027 session. Given eleven consecutive years of advocacy and growing public support, recreational home grow legalization in Washington is a matter of when rather than if. We will update this page when the law changes. See the Washington home grow laws guide for the latest.

Washington spans USDA Zones 4-9, with very different growing conditions on either side of the Cascades. Western Washington — Seattle, Tacoma, Olympia — is cool, cloudy, and damp with a season running roughly late May through September. Mold and botrytis resistance are essential for outdoor grows on the west side. Autoflowering varieties that finish before the wet fall weather sets in are a strong choice. Eastern Washington — Spokane, the Yakima Valley — is warmer and drier with a longer, more forgiving season where full-season and short-season photoperiod varieties perform well. Enter your zip code on our zone map for your specific dates, then browse autoflowering varieties or short-season varieties.

Most Washington outdoor growers start seeds indoors in late March to April and transplant after the last frost, typically late April to mid-May depending on location. Western Washington growers should prioritize finishing dates — varieties that wrap up in September fare much better than those that push into October when fall rains arrive. Eastern Washington growers have more flexibility with a longer, drier window. Check your zip code on our zone map for specific frost dates, or see our germination guide for step-by-step starting instructions.
