Best Strains to Grow in Seattle

Last updated: 4 October 2022

Best strains to grow in Seattle

Washington state definitely loves its weed. It was the second state to legalize recreational cannabis sales, and residents spend hundreds of millions of dollars on weed every year. But what if you don’t want to spend your hard-earned money on weed? Cultivate it yourself with our guide to the best strains to grow in Seattle.

The first thing to note here is that growing weed in the Seattle area can be difficult. First, growers have to deal with Washington state’s marijuana laws, which prohibit home growing by private individuals. That’s why for buying cannabis seeds in Seattle you need to resort to safe online shopping. Second, the region has a wet, cool climate that favors many types of vegetation. However, weed isn’t one of these plants. That’s why it’s so important to know what strains of cannabis grow best in the Seattle climate.

Top 10 Cannabis Strains to Grow in Seattle

Seattle generally has a short growing season with limited sunlight. As a result, we’ve mainly stuck to plants that have shorter flowering phases, such as autoflowering strains. Another benefit to autoflowering strains is that they often don’t grow very tall. That will help you keep your garden stealthy – since you can’t legally grow weed here, this is an important factor.

Northern Lights (Sensi Seeds)

Northern Lights tops our list of the best Seattle strains, and it’s not hard to see why.

Even non-smokers know about Northern Lights. Anecdotal evidence suggests that Northern Lights was first bred in the Seattle area before it became famous in the Netherlands. This legendary Afghan and Thai cross is a powerful Indica that grows well indoors and has a low, shrubby profile. Northern Lights is also truly northern at heart, as it can withstand cool temperatures really well. It takes between 45 and 50 days to fully mature once it reaches the flowering cycle. Don’t sleep on this strain if you like the calming, chilled-out vibes of a pure Indica.

2 Fast & 2 Vast Auto (Heavyweight Seeds)

Number two on our list of the top Seattle strains is 2 Fast & 2 Vast Auto. This strain is what happens when breeder Heavyweight Seeds combines a giggly, relaxing high that provides introspection and creativity with a respectable 20% THC and just under 1% CBD.

This Fast and Vast and Northern Lights Auto cross is ideal for the Seattle climate. It only takes 56 days to fully mature from seed, and its maximum height is somewhere around 40 inches (100cm), making it perfect for stealth gardens. No wonder it’s one of the best strains to grow in Seattle.

Wedding Cake Auto (Original Sensible Seeds)

Wedding Cake Auto is a fairly new hybrid created by crossing Cherry Pie and Girl Scout Cookies (GSC). With a combination of tangy and spicy flavors and a mellow high, this strain is perfect for any time of day.

Wedding Cake Auto is also a great strain to grow in Seattle. This weed strain usually only spends about 5 weeks in the flowering phase thanks to its autoflowering genetics. Moreover, it doesn’t grow very tall, usually reaching heights of around 31 inches (80cm). That makes it a great marijuana strain for growing outdoors in the Seattle climate!

Girl Scout Cookies Auto (Garden Of Green Seeds)

It’s hard to go wrong with Girl Scout Cookies, one of the most famous strains of the last decade. Make it an autoflowering variety by mixing Girl Scout Cookies and Cannabis Ruderalis, and you have one of the best weed strains for growers in Seattle. Its high is simultaneously relaxing and uplifting, and it boasts a complex flavor profile with tons of sweetness and citrus.

Girl Scout Cookies Auto is also ideal for Seattle’s climate. Since it’s both Indica-dominant and an autoflowering strain, it’s easy to grow both indoors and outdoors. It develops a low, bulky shape and is easy to train to grow wider instead of taller.

Bruce Banner #3 Fast (Original Sensible Seeds)

No list of the top ten strains in Seattle would be complete without Bruce Banner #3 Fast. This strain grows big, green, and mean, just like the comic book character’s alter ego, the Hulk. Bruce Banner #3 Fast is a three-way cross between Colorado Ghost OG, Strawberry Diesel, and Black Domina, creating a potent Indica-dominant hybrid.

Orange Sherbet Auto (FastBuds)

Use LST to keep plants growing outward instead of upward to maximize your grow space, and you’ll see why Orange Sherbet Auto is one of the most popular strains to grow in Seattle right now.

Extreme Impact Auto (Heavyweight Seeds)

Here’s a strain that doesn’t pull any punches. Extreme Impact Auto is a Mazar Auto and Fast Vast Auto cross with about 21% THC, plus a dash of CBD to boot. The addition of this strain’s powerful, in-your-face hashy flavor makes it an instant classic.

High CBD Strains to Grow in Seattle

Sometimes, some smokers want a different experience: CBD. They’re not looking for the high-flying zing of a Sativa or the mellow relaxation of an Indica. Instead, they may be medical patients seeking relief, or may simply enjoy the mellow vibes of cannabis without the psychoactive effects. Whatever your reason, keep this list in mind if you’re looking for the best high CBD strains to grow in Seattle.

CBD Auto 20:1 (FastBuds)

Occupying the top slot on our list of Seattle’s best high-CBD strains is CBD Auto 20:1. By crossing CBD and a Ruderalis, FastBuds has engineered a strain with nearly 20% CBD and negligible THC.

Stress Killer Automatic CBD (RQS)

Another great autoflowering CBD strain is Stress Killer Automatic CBD. Legendary breeder Royal Queen Seeds created this majestic marijuana by mixing Lemon Shining Silver Haze, Juanita la Lagrimosa, and a Ruderalis, and the result definitely measures up. Plus, it has an unbeatable citrus flavor!

CBD Lemon Potion Auto (Barney’s Farm)

For a delicious hybrid with a heaping portion of CBD, choose CBD Lemon Potion Auto. With about 15% THC and 10% CBD, this strain is ideal for any grower who wants CBD in their cannabis without totally eliminating the THC.

CBD Lemon Potion Auto does take a little longer to mature than most of the strains here. It usually finishes in about 70 days – just slightly over the 2-month growing period that many autoflowers maintain.
