Some cannabis strains are geared to indoor grows, while others thrive outdoors. These five strains are perfectly primed to flourish under the sun, delivering satisfying yields of potent and flavourful bud. Which one(s) will you grow?

Hallucinogens, cannabis research, mind

Growing cannabis outdoors is extremely rewarding, if mostly for the large yields and low cost of operation. Many of Royal Queen Seeds’ varieties take very well to the outdoors, thriving under the natural sunlight. That said, when it comes to outdoor growing, the strain you choose can make all the difference between success or failure. For that reason, we’ve put together a list of our top 5 outdoor strains—cultivars that are ready to harvest by late September.

With the selections on this list, you can avoid unnecessary trouble with rain and frost in October and November. While other growers are busy inspecting their developing buds for mould, you’ll be drying and curing your harvest and filling up your jars. If you missed out on our top 5 strains for colder and warmer climates, feel free to give those a look as well!

  2. Top 5 early-finishing cannabis strains to grow outdoors in 2020

    3. Northern light
    4. Sweet zz
    5. Green crack punch


    When selecting a cannabis strain to grow outdoors, speed shouldn’t be the only concern. It’s also important for plants to be productive, to have a good aroma, and to induce a pleasant effect once smoked.

    Here are the traits your outdoor strain needs to include:

    Fast flowering so you can beat rainy weather in fall
    • Good natural resistance to mould and pests
    High yields
    • Great potency, aroma, and flavour
    Superb effect


    Now that we know what makes a good strain to grow outdoors, it’s time to look at some recommended cultivars. Here are 5 of the best early-finishing outdoor strains to grow in 2020:

    1. Honey Cream Fast Flowering

    Honey Cream Fast Flowering is one of our recently updated favourites. This variety is very popular in Spain due to its sweet, creamy aroma, but you can grow it virtually anywhere in Europe.

    Its remarkably short flowering time of only 6–7 weeks makes it a good strain in regions where the weather can get ugly early in fall. However, grow it in July and August, and this will provide a sufficient window for Honey Cream to receive a lot of sunlight so she can bulk up. This way, you can harvest good amounts of sweet, potent buds in September.

    Besides its short flowering period and amazing flavour, Honey Cream convinces with a solid indica background composed of BlueBlack (Blueberry x Black Domina), Maple Leaf Indica (100% Afghan indica), and White Rhino. These three strains give Honey Cream FF an indica-dominant genetic profile, but there’s also a decent amount of sativa potency from White Widow, the predecessor of White Rhino. When things go well, plants reach outdoor heights of 180–250cm and yield up to 675g/plant.

    Honey Cream (Fast Flowering)
    Honey Cream (Fast Flowering)
    BlueBlack x Maple Leaf Indica x White Rhino
    500 – 550 gr/m2
    100 – 160 cm
    7 – 8 weeks
    THC: 16%
    Sativa 35% Indica 65%
    625 – 675 gr/plant
    180 – 250 cm
    Early October

    2. Speedy Chile Fast Flowering

    Next up is Speedy Chile. This girl combines Early Skunk genetics with several Chile indica landraces, although a third generation autoflowering plant is partly responsible for its very short flowering time of just 6 weeks (42 days!).

    But make no mistake, Speedy Chile is a photoperiod strain that flowers depending on the amount of available light hours per day. One could say that fast flowering strains are the next breeding evolution after autoflowering genetics: These strains produce high THC levels while maintaining an incredibly short total crop time.

    For outdoor cultivators and novice growers, choosing Speedy Chile Fast Flowering is a wise decision. You can fill your bags with buds in early September, which leaves no room for uncertainty regarding climate or mould issues. And the buds you gather will be excellent in their own right, producing sumptuous flavours of fruit and pine alongside a THC content of 16%.

    THC: 16%
    Sativa 30% Indica 70%
    450 – 500 gr/plant
    100 – 170 cm
    Early September
    Calming, Laughter

    3. Northern Light

    A true cannabis classic, Northern Light is an indica superstar created from eleven different seeds of Afghan and Thai genetics. Bred and hybridised repeatedly, the exact genetic breakdown remains a mystery. However, Northern Light itself is the basis for many award-winning cannabis strains.

    A fantastic outdoor strain, Northern Light feminized will push to over 2m under the sun. Then, come harvest time, you will be rewarded with dense, resin-covered nuggets and a giant main cola. The yields are quite impressive. Given full access to light and sufficient nutrition, plants produce as much as 575–625g/plant in late September (around 8–9 weeks of bloom indoors).

    Northern Light is a legend for a reason. This potent indica has the power to put you straight into couch-lock territory. This is the ideal strain if you are looking for a strong nighttime stone to help you relax and sleep. As you smoke or vape, you’ll also be treated to sumptuous flavours of citrus, spice, and fruit.

    Sativa 0% Indica 100%
    575 – 625 gr/plant
    180 – 220 cm
    Late September
    Balanced, Clear, Stoned

    4. Sweet ZZ

    Sweet ZZ is our own version of the legendary Zkittlez. With its fruity aroma and succulent flavour, it’s top favourite for all candy-loving cannabis growers.

    Bred from Grape Ape and Grapefruit, this indica-dominant hybrid takes only 7–9 weeks to flower, so you can cut this plant down in late September outdoors. When you do, better bring an extra bag, as this girl can yield up to 600g/plant in good conditions.

    Although Sweet ZZ is indica-dominant, its effects are firmly focused on the mind, not the body. It will hit you with waves of uplifting thoughts and feel-good vibes. Add its delicious flavours of citrus, berries, and candy, and you get the physical embodiment of happiness in one awesome smoke. Good thing it’s not ultra-powerful with 15–20% THC. This way, you can savour its taste and effect for a long time before reaching the point of no return.

    Sweet ZZ

    Grape Ape x Grapefruit
    550 – 600 gr/m2
    80 – 140 cm
    7 – 9 weeks

    Sativa 20% Indica 80%
    500 – 550 gr/plant
    160 – 200 cm
    Late September
    Calming, Stoned

    5. Green Crack Punch

    Hailing from Purple Punch and Green Crack, Green Crack Punch is a great example of what happens when opposites attract. Purple Punch is a superior indica-dominant strain that’s great for relaxing and easing tension, while Green Crack is a Duracell Bunny of a strain that will keep you upbeat and full of motivation.

    The result? A balanced hybrid with an average THC content of 20% that will keep you energised and inspired. Eventually, the effects will make their way to your muscles and relax your physical being. A treat to the senses, Green Crack Punch has attractive hues of bright pinks and oranges accompanied by a smooth smoke with a fruity taste.

    An excellent choice for first-time outdoor growers, Green Crack Punch is a low-maintenance plant that can tolerate small fluxes in feeding and lighting. Suitable for a wide variety of environments, this one will be ready for harvest come late September (Around 7–8 weeks of bloom indoors), with a haul of 550–600g/plant.

    The Best Strains to Grow Outdoors

    A s the skies begin to clear and the temperatures begin to rise, many people are looking for fun and rewarding outdoor activities for the summer months. For some marijuana enthusiasts, that means giving growing their own cannabis plants outside a try.

    The benefits to growing marijuana outdoors range from not having to buy weed for a while to the satisfaction of getting stoned through your own hard work and ingenuity – like hand crafting your own bong, but better.

    If you’re a novice looking to find out how green your thumb actually is, below are some of the best outdoor strains to try growing this summer.

    Best Outdoor Strains to Grow

    While there are many strains that produce excellent flower when grown outdoors in the summer months, these are some of our picks for the best outdoor strains to start with! Plus, many of the strains listed are great for beginners, too. So, find one you like and get started on your outdoor growing adventure!

    White Widow

    There’s a lot that can be said for White Widow’s appearance and potency, especially for those who still remember the legends of this strain coming out of Amsterdam. The fact that this Northern European strain is also one of the best outdoor strains for summer may come as a surprise for many, especially how easily it takes to hot, dry regions.

    While the combination of harsh sunlight and high winds that can dry out plants usually means putting in extra effort into your grow, White Widow is your easy button. The gooey coating of resin that gives White Widow its legendary frosty appearance also serves as an excellent defense mechanism against insects and fungi. Combine that with this sativa-dominant hybrid’s remarkable tolerance for high temperatures, even enduring those random heat waves, and you have yourself the ideal summer strain to grow.

    Once harvested, the euphoria and energy White Widow gives you will result in plenty of creativity and conversation, perfect for those lazy, hot summer nights on the porch.

    Durban Poison

    A pure sativa landrace strain originating in South Africa, Durban Poison is a great strain to grow outdoors and can be grown almost any time of the year so long as the weather is decent during harvest time. This strain is known to grow very tall outdoors and is perfect for any sativa lover.

    Besides being one of the best outdoor strains, Durban Poison is also one of the best daytime strains to enjoy during summer due to its clear, functional effects and energetic high. Be sure to give it a try if you’re going on an activity like a hike or bike ride!

    Super Silver Haze

    If you’re looking for a heavier sativa with White Widow’s outdoor ruggedness and ease, Super Silver Haze is one of the best outdoor strains for summer growing. For the relatively little effort you have to put in once the seeds are in the ground, Super Silver Haze will spread its roots and quickly produce high-quality, high-volume yields even throughout the hottest days.

    It is the lovechild of such notable strains as Northern Lights, Haze, and Skunk. Super Silver Haze produces a fragrant, skunky, and spicy bud that both lifts the spirits and relaxes the body. This strain is perfect to smoke in early September when it’s time to harvest and you’ll need a little inspiration while you trim. Just be certain to give each plant plenty of space to make room for those big yields.

    Grape Ape

    A cross between Skunk #1 and Afghani, Grape Ape is a popular strain both for its upbeat body high as well as its distinctive grape flavor. Although it’s one of the best outdoor strains, Grape Ape does need a little tenderness. The plant thrives in sheltered outdoor spots, so look for a patch of soil where there’s still plenty of sunlight, heat and humidity.

    Give your Grape Ape plants what they want, maintain them regularly and each plant can return a yield of about 750 grams. The deep purple leaves and dense, compact buds offer a carefree, floaty relaxation for those summer days when you’ve got a towel, some swim trunks and nowhere to be but by the water.

    A favorite among novice growers, LSD makes the list of best outdoor strains due to its natural resistance to common cannabis pests and fungi. Even better, LSD is a low-maintenance strain that flourishes in the summer heat. Similar to Grape Ape, LSD grows best in sheltered outdoor areas, so be sure to plant your seeds in a shielded spot with plenty of warmth and sunshine.

    Then, sit back (within reason) and let nature take care of the rest. LSD plants will usually flower in about 9 -10 weeks. A cross between Mazar and Skunk #1 out of Amsterdam, LSD appropriately delivers a vivid, almost psychedelic experience with a powerful body buzz and cerebral high. This is the perfect strain for summer music concerts or just sitting inside with a couple beers and a sci-fi movie on the screen.

    Blue Dream

    Blue Dream has been a staple of outdoor cannabis crops for quite some time, boasting big yields and a relatively low-effort growth process. One of the best outdoor strains for novice growers, Blue Dream does well in many summer climates and will take all the sunlight that you can give it.

    Although typically grown in hydro to maximize yields, growing Blue Dream outdoors in soil can really bring out the smooth, blueberry flavor this strain is known for. With extremely uplifting and cerebral effects, Blue Dream is a great strain for creative types looking to work on their next summer project. Bring your guitar or art supplies to the park with a joint of this one and make something new in that summer sunshine.

    This OG Kush nugget is dusted with trichomes and smells of earthy pine, sour lemon with woody undertones.

    One of the most famous strains in America (and best outdoor strains), the origins of OG Kush are rather unknown – although many believe it came out of Florida. OG Kush quickly gained a reputation amongst growers for its potent high and mellow, calming effects.

    OG Kush thrives in warmer climates and is one of the simpler strains for novices to grow. Reaching up to 9 feet when grown outdoors, the buds give off a distinct earthy pine and sour lemon scent with woody undertones. Despite growing so tall, OG Kush still has plenty of energy to produce flower and It’s known to yield up to 1100 grams of bud per plant. OG Kush has a reputation as one of the “stonier” strains, so be sure to save it for the end of the day when you’re just getting back home and ready to sleep off your weekend.

    Top 10 Feminized Outdoor Cannabis Strains

    Spring is here and it is time to start putting some seeds in the ground. To help out, we have put together a list of our top 10 feminized cannabis seeds for outdoor growing.

    Although outdoor cannabis cultivation comes with a host of challenges, the return makes it more than worthwhile. Plus, it’s a much more pleasant environment in which to watch your crop develop. Nothing compares to watering, feeding, and pruning under the warm rays of the sun, with birdsong in the air.

    But not all strains are suited to life in the great outdoors. Some can’t handle the slight shifts in temperature, much less the torrential rains, that outdoor cultivation brings. It’s vital to start out with the right genetics to obtain an optimal outdoor harvest. Outdoor plants are also much more susceptible to pests and fungal diseases. It’s important to select cultivars partly based on their hardiness and resistance to these threats.

    With that said, it’s not all about defence. Outdoor growers often have the luxury of more space, and with this comes bigger yields. Part of the strain selection process for an outdoor grow involves assessing the production potential of a particular variety.

    Below are the top 10 feminized cannabis strains to grow outdoors in 2020 for best results.

    Gelato — Zamnesia Seeds

    Zamnesia’s Gelato is a descendant of the original taste-loaded strain stemming from San Francisco. Gelato rose to fame riding on the waves of its delicious, sugary terpene profile. Zamnesia breeders put their own spin on this legend, further enhancing the taste by breeding it with an in-house phenotype, Gelato 33, alongside Wedding Cake. This genetic marriage resulted in a slightly indica-dominant variety that achieves a mind-melting THC level of 26%. The effects are smack bang in the middle of stoning euphoria and cerebral stimulation.

    Gelato is well suited to growing outdoors. Fertile soil and adequate sunlight send terpene production into overdrive, bringing her flavour to new heights. She grows to a height of 50–200cm, but can be kept shorter using LST. Gelato produces a rewarding yield of up to 400g/plant and will be ready to harvest in October.

    White Widow — Ministry Of Cannabis

    White Widow is a name known all throughout the cannabis world—and for good reason. Since emerging from the Netherlands in the 1990s, this legendary lady has scooped up plenty of awards, becoming a firm favourite among smokers, growers, and breeders alike. Her sativa dominance and high THC level make for a satisfying high that raises the mood and eases aches and pains. Her colas are tall and tapered, and ooze a resin loaded with the terpenes limonene, myrcene, and caryophyllene.

    White Widow’s abundant resin production makes her an ideal outdoor strain, especially for beginners. This viscous layer protects her—to some degree—against pests, fungal infection, and high temperatures. Although her yield isn’t the largest, her pleasant effects make up for the lack of volume. She’ll produce 300g/plant, ready to harvest during October.

    Hulkberry — Royal Queen Seeds

    Hulkberry is a go-to cultivar for outdoor growers seeking a mammoth yield. This strain was created by RQS breeders with a simple goal in mind: optimal returns. Their search for maximum output led them to cross OG Kush with Strawberry Diesel. Sure, the progeny of this pairing yields heavy, but she also offers a THC content of 27%. A small toke from this sativa-dominant beast will send a stimulating high charging through the nervous system. Handle with care!

    Hulkberry’s dense and colourful flowers are far from a scarce resource. This plant will soar to a height of 2m and churn out up to 700g. Prepare to start harvesting and trimming this bounty toward the end of September.

    Northern Lights — Sensi Seeds

    New strains come and go, but some stick around forever. Northern Lights is one such timeless classic. This 90% indica variety is prized for its heavy stone, a trait that has earned it many competition wins. Despite her popularity, the precise origins of this legend remain shrouded in mystery. Regardless, she came onto the scene during the mid-1980s and blew minds with her sedating and musclemelting properties.

    Northern Lights is a superb outdoor variety. Her short flowering time makes her a viable strain in areas with a short growing season. She’ll ripen fast and avoid the first frost in northern latitudes. She grows tall for an indica specimen, often peaking at 2.5m, and produces large flowers with beautiful orange pistils.

    Fast Bud Outdoor – Spliff Seeds

    Fast Bud Outdoor is a sativa-dominant strain that, as the name suggests, flourishes outside. This strain derives from a combination of Early Pearl x Mexican Sativa x Californian Sativa. The result is a cultivar that easily reaches heights of around 250cm and produces a huge yield of about 600–650g/plant. With an amazing THC content, her high is characteristically sativa in the best way possible. Whether smoked or vaped, Fast Bud Outdoor provides an uplifting social stone accented by a floral and peppery flavour that’s dynamic and unique. And if it wasn’t clear from the name, this strain is fast to finish.

    Runtz — Zamnesia Seeds

    As the result of a potent pairing of Gelato and Zkittlez (two powerhouse strains in their own right) comes Runtz. This is a 50/50 hybrid strain that is simply perfect for cultivating outdoors. She likes to spread out, often reaching heights of around 2 metres, and is a beautiful plant to watch grow. She boasts purple and lime green colouring with plenty of resin that is bound to stop many in their tracks.

    Ready to harvest in late September/early October, she’ll be ready before you know it. Providing larger yields of up to 450g/plant, her buds are definitely something to behold. Because of her rich parentage, Runtz offers up some sweet fruity flavours that are reminiscent of sugary candy. Complete with some huge THC levels of around 27%, she offers up effects that tap deep into her sativa and indica roots. Expect a powerful high that has moments of euphoria and will stone and relax even the most seasoned of stoners.

    Durban Poison — Dutch Passion

    Durban Poison stems from a lineage of South African landraces. Her genetically stable ancestors—the result of generations of natural inbreeding—were brought to the US during the 1970s. Ed Rosenthal, the so-called “guru of ganja” was the one who introduced these seeds to the West. The genetics were passed along to several different breeders before eventually ending up in Amsterdam, where they have since become a coffeeshop favourite. This 100% pure, unadulterated sativa provides a pleasant high that’s unparalleled in its clarity and lucidity. A modest THC content of 8–9% is ideal for the daytime when looking to remain fully functional.

    Her towering height and mould resistance make her suitable for outdoor cultivation. She’ll provide rewarding yields after a brief flowering time of 8–9 weeks.

    CBD Therapy — CBD Crew

    CBD Therapy is the result of a rigorous breeding programme that sought to broaden the gap between THC and CBD concentrations. The strain set the standard for up-and-coming CBD varieties, and was one of the first in the world to reach a THC:CBD ratio of 1:20. This cultivar provides massive amounts of cannabidiol and doesn’t induce any psychotropic effects. The strain is effective when smoked, but can also be used to make high-potency CBD extracts.

    CBD Therapy performs well outdoors, providing colourful colas endowed with sweet aromas. The strain produces a medium-sized yield after flowering for 8–9 weeks.

    Super Silver Haze — Zamnesia Seeds

    Super Silver Haze is a straight-up icon. This sativa-dominant progeny of Haze, Skunk, and Northern Lights is a productive wonder. After all, it would be impossible for such a stellar array of genetics to produce subpar results. She puts out large colas decorated in orange and white pistils and layered in shimmering resin. These flowers produce a lively and active high that prompts users to get outdoors and move their bodies. Shining Silver Haze is an excellent wake-and-bake strain to get the day started off on the right foot.

    Super Silver Haze is easy to manage, reaching a medium height outdoors. She’ll churn out a yield of up to 550g/plant in October after a flowering period of 9–10 weeks.

    Money Maker — Strain Hunters

    Money Maker will earn commercial growers some serious cash, and provide home growers with a substantial stash. The globe-trotting, landrace-seeking Strain Hunters created this behemoth by breeding Original Master Kush, Hindu Kush, and Skunk. She features a genetic makeup of 70% indica and 30% sativa—a ratio that provides a soothing body high.

    Money Maker displays a typical indica growth pattern and maintains a short height. Despite her size, she’ll pump out a colossal yield of 1kg/plant outdoors. All of these buds will be ready to harvest after only 8 weeks of flowering.
