Top 10 High-Yielding Outdoor Feminized Cannabis Strains
Growing weed outdoors often provides more space, which results in bigger yields. However, poor weather conditions, pests, and diseases can hamper results. To ensure massive yields every single time, you need to start with the best genetics for the job. Below, meet 10 of the highest-yielding cannabis strains to add to your garden.
Contents:
Figuring out where to cultivate your cannabis crop is one of the very first steps in getting a grow started. Then, once you’ve decided, you’ve got to find the strains that will make the very most of your chosen environment. If you're looking to really boost your yield potential, certain varieties are better suited to this job.
Here we review our top 10 highest-yielding outdoor feminized cannabis strains. All of these cultivars thrive in hot southern climates, and some will churn out perfectly respectable harvests even in cooler northern regions.
Below, explore how to cultivate these varieties for optimal results, diving into their growth through detailed journals, and anticipate the experience they offer when smoked.
Why Grow Cannabis Outdoors?
For the most part, when we think of growing cannabis in the modern era, we think of foil-lined rooms with huge lights and fans. However, in many cases, the very best results are achievable when we grow weed as nature intended: outdoors.
There are many benefits to growing indoors, such as control over pretty much every variable. But it’s also expensive, very involved, and no lights can compare to the power and spectrum of the sun in the summer.
So for those living in a suitable climate with enough space, growing outdoors is a fantastic option. Not only is sunlight free and the best light source available, but plants grown outdoors can become huge, resulting in outrageously big yields. Plus, the natural cadence of the seasons will dictate the plants’ movement from one stage to another. All you need to do is keep them happy.
Green Gelato
Green Gelato bursts right out of the gate with impressive germination speed. This variety performs well whether sown directly into her final pot or started in cells and then transplanted once the first true leaves exceed the circumference of the original container.
Avoid overwatering in the early stages and you’ll have yourself a healthy plant standing at around 19cm during week three of growth. Plants will thrive at an average temperature of 25°C and relative humidity of 50% during veg. Ensure good sun exposure and keep plants covered from excess rainfall using row covers or a polytunnel. Your plants will transition to bloom as seasonal light begins to wane. Expect pre-flowers to quickly develop into young buds, and for a weak but noticeable smell to manifest. If left untrained and given enough room to spread her roots, Green Gelato will stretch to a height of 200cm. Expect plants to take on a deep purple hue close to harvest, and prepare to rake in up to 800g/plant in early October.
As the progeny of Sunset Sherbet and Thin Mint Girl Scout Cookies, Green Gelato features a slightly indica-dominant genetic profile. Brace yourself for a mind-blowing high fueled by a THC level of 27%, and enjoy flavors of citrus, earth, mint, pepper, and vanilla with every hit.

Punch Pie
Punch Pie will prove her worth in your garden as one of the highest-yielding strains outdoors. Soak these feminized seeds for around 12 hours before sowing them into cell trays with a sprinkle of mycorrhizal fungi to spur root development. Once the first true leaves grow beyond the edges of each cell, transplant seedlings directly into the ground or into large containers outdoors once the risk of frost has passed. Use row covers or cloches during the first two weeks to accelerate growth. Punch Pie will put on some serious mass during the vegetative phase, developing a sturdy stem and short internodes that give rise to a bushy canopy. As she transitions into bloom, defoliate lightly and emphasize phosphorus and potassium in your feeding regimen. Over the next several weeks, watch your plant stretch to 150cm and put out a large central cola alongside plenty of smaller-sized inflorescences. Get enough stash jars ready to handle up to 750g/plant once harvest comes around in late September.
Punch Pie descends from parent strains Purple Punch and Purple Kush, and boasts a THC content of 22%. Experience her relaxing and euphoric high alongside tastes of blueberry, candy, and earthiness.

Trainwreck
As one of the greatest outdoor weed strains, Trainwreck gains serious momentum early on in the growing cycle. As the descendant of hardy landrace genetics, you can sow this strain directly into its final position. Make sure to use netting to protect young shoots from birds and pests, and cover if the risk of frost still remains. Top and train your plants around the third week of veg to limit their height to 150cm. Otherwise, let them stretch to 200cm during bloom. Foliar sprays of seaweed or fish emulsion will keep plants happy during veg, alongside an average temperature of 25°C. As your plants switch to flowering, expect them to surge in height. Flowers will start to mature quickly, and companion plants such as basil and rosemary will help with odour control. Trainwreck boasts large, tapered buds caked in resin. Withhold all nutrients during the final two weeks of bloom to force plants to use up their nutrient stores and provide tastier buds. Prepare to pull in up to 700g/plant in October.
What can you expect after trimming, drying, and curing these buds? Enjoy a mellow and euphoric high paired with pleasant hints of citrus, herbs, mint, and pine.

Shogun
This legendary outdoor sativa will fill your stash jars to the brim. After successful germination, your Shogun plant will reach a height of almost 10cm by the end of the second week of veg if grown in a 2-litre pot. As things start to warm up outdoors, transplant into a sunny spot enriched with plenty of organic matter, such as mature compost or worm castings.
Within another couple of weeks, your plant will have reached 15–20cm if exposed to daytime temperatures of 25–30°C. Consider watering with drip irrigation if you’re contending with an arid climate. By the time your plant starts entering bloom, it’ll stand at around 150cm. Over the next week or so, it’ll gain another 40cm, maxing out at 190cm. Provide a steady supply of bloom nutrients and trigger a flush two weeks before harvesting a colossal yield of 650–750g/plant in late October.
The offspring of Amnesia Haze and GG4, Shogun possesses a THC content of 25% that drives a long-lasting and uplifting high. Pleasant tastes of citrus, earth, and pine are a bonus.

Lemon Shining Silver Haze
Lemon Shining Silver Haze seeds quickly burst forth into vigorous vegging plants. This award-winning variety puts her sativa dominance on full display during the vegetative phase and develops long internodes and plenty of waxy and healthy fan leaves adorned with thin leaflets.

Unless trained, plants will peak at around 120cm before entering bloom. During flowering, this variety quickly develops large, aromatic colas and stretches to a maximum height of 170cm. Consider staking particularly bud-laden branches in regions with harsh weather to prevent bending and snapping. Come harvest time in mid-October, you’ll find yourself busy processing up to 700g/plant.
Aside from ranking as one of the biggest-yielding outdoor strains, Lemon Shining Silver Haze also treats growers to a delightful high and moreish taste. Her THC level of 21% exerts a clear-headed and rejuvenating effect, whereas her terpenes serve up flavors of fruit, with citrus dominating the mix.

Amnesia Haze
Amnesia Haze offers astonishing results when grown outdoors. However, to get the maximum outcome from this variety, you’ll need to pair her with a warm and sunny climate. If you’re in a cooler region, she’ll do best in a greenhouse or polytunnel. Throughout veg, this strain will exhibit rapid growth and put out plenty of large and broad fan leaves. With room to spread their roots, plants will develop a tall and lanky main stem with long internodes.
Top and tie down your plants before flowering to limit their size to around 40cm pre-bloom. Otherwise, make sure you have enough space to handle 210cm-tall giants after stretching. If you leave plants untrained, make an effort to defoliate and aerate the canopy to protect the large central cola from excess humidity and subsequent mold. Once harvest comes around in late October, you can expect to reel in up to 700g/plant.
As the successor of Original Amnesia Haze, this cultivar combines a THC value of 22% with medium levels of CBD to generate a long-lasting and stimulating effect. Tastes of herbs, pepper, and citrus make joints hard to put down.

Transplant seedlings out into their final spots and give them a dose of compost tea to help establish a protective microbiome. This stout and bushy hybrid will grow to 100cm during veg in left untrained, exhibiting short internodes and wide, turgid, and luscious fan leaves. Throughout bloom, expect plants to pack on an extra 40cm and to develop a thick and frosty coating of trichomes. Yields of up to 700g/plant in late September will keep you elevated for months to come.
HulkBerry inherited the best traits of parent strains OG Kush and Strawberry Diesel. Her massive THC content of 27% means all users should approach these buds with caution. Strap in for a hard-hitting, uplifting high and flavors of citrus, diesel, herbs, and pepper to boot.

Royal Moby
Royal Moby has more than earned its place among high-yield outdoor seeds. Grow this strain in an area with warm weather and long summers, and you’ll unlock truly massive returns. Sow seeds into small seedling containers, and germinate companion plant species at the same time to defend your crop throughout the growing season.
.jpg "Royal Moby")
Once your seedling reaches a height of around 10cm, transplant it into a sunny but protected outdoor position. By the fifth week of veg, you’ll have a bushy plant with a dense canopy on your hands. Start defoliating now to allow light and air into the canopy. From a height of 80cm at the end of veg, your plant will stretch up to 140cm in early bloom. Enjoy the show as Royal Moby churns out a multitude of thick, bulbous, and sticky buds. Prepare to harvest up to 700g/plant in late October.
By crossing Haze and White Widow, Royal Queen Seeds successfully brought Royal Moby into the world. Her THC content of 21% offers a clear-headed and slightly stoning high, while her diverse terpene profile treats smokers to tastes of blueberry, citrus, pepper, and herbs.

Purple Queen
Not only does Purple Queen provide fantastic yields, but this pigment-filled beauty will add some serious color to your garden. Boost germination rates using the paper towel method and then sow germinated seeds into small seedling pots. Once at a height of 10cm, transplant into larger containers or directly into the ground.

This strain will perform best with an average temperature of around 27°C and a humidity of 50% during veg. Consider growing Purple Queen under cover if your environment fails to meet the optimal conditions. You’ll start to notice a subtle aroma fill the air as pre-flowers emerge during early bloom. Provide enough flowering macronutrients and you’ll have a canopy bending under the weight of big purple buds. Get your gear together and harvest 650–700g/plant in October.
Purple Queen inherited a stunning purple appearance from Hindu Kush and Purple Afghani. Aside from her good looks, this strain produces a euphoric high complemented by flavors of citrus and earthiness.

Gushers
Gushers rounds off our list of the highest-yielding outdoor strains. Last but by no means least, this robust and hardy strain faces off well against the elements to provide bulky yields at the end of a brief flowering phase. Leverage the paper towel method for optimal germination and raise seedlings indoors until the risk of frost passes.
Transplant into soil amended with organic matter and throw in some bioinoculants for good measure. Exposed to temperatures of 25°C and high humidity levels of 70%, this cultivar will grow to around 100cm by the time the flowering phase swings around, and will peak at 150cm after stretching during early bloom. Her short internodes result in a dense canopy filled with long and thick colas. Flush during the final two weeks of bloom, and get your trimming scissors ready to process 650–700g/plant in early October.
When firing up a bowl or joint packed full of Gushers flowers, expect her THC content of 24% to swiftly land a heavy body high paired with a mentally uplifting effect. Tastes of cookies and fruit will leave you pining for another hit in no time.
