Cannabis

Since Northern Lights Feminized is highly-regarded and has been awarded many times over, you’d expect her to have an illustrious heritage - and you wouldn’t be wrong. Though not 100% certain, most in the cannabis community agree that this herb's genetics can be traced back to two prominent landrace strains, since she clearly takes her blissful, relaxing effects from Afghani (alongside her excellent growth traits) and her euphoric buzz from her Sativa-side, where Thai comes into play.

A hit with recreational and medicinal users, Northern Lights is full of sweet pine scents and spicy flavors, delighting the taste buds before she begins to delight the mind with her stimulating mood-enhancement. As her Indica-dominance takes the stage, your body will relax and unwind to the tune of calm tranquility before finally, her high sends you off to dreamland.

For those seeking relief from maladies via medicinal marijuana, Northern Lights Fem can free the mind of stress and depression, improve lack of appetite, resolve insomnia and provide great comfort for a variety of physiological issues including migraines and arthritis.

If you’re a beginner or an experienced grower, this is a strain that boasts hardiness to adverse weather conditions, resilience to pests and disease, and can recover from most mistakes. Throw in the fact that these seeds are feminized, and all you’re left with is the requirement to keep her trimmed and pruned - it’s hard to go wrong with Northern Lights, and her yields make her well worth the little effort that’s required

Northern Lights Feminized

Once referred to as the King of Sativa strains, Super Silver Haze Feminized earned its title fair and square. With a THC content around 23%, it’s not the strongest strain on the market, but its effects simply cannot be argued with. It’s no coincidence whatsoever that this is one of the most famous Sativa-heavy hybrids on the 420 scene.

Multiple High Times Cannabis Cup Winner

Strain Info

Super Silver Haze’s powerhouse ancestry includes cannabis classics Skunk #1, Haze and Northern Lights, all mixed together to create a herb that delivers a euphoric and energizing high wrapped up in an earthy lemon flavor. The plant dominated the High Times Cannabis Cup in the 90s, winning in ‘97, ‘98 and ‘99 consecutively.

This superstar’s meteoric ascent comes as no surprise. She’s said to relieve a wide array of physical and psychological ailments, and recreational users adore her soaring, energizing, cerebral high – swiftly followed by a deep, contemplative stone. 

Citrusy and sweet with just a hint of skunkiness, Super Silver Haze Feminized is aromatic without being overpowering, with fresh and summery notes that are just as enjoyable as her effects.

Growing Super Silver Haze Feminized 

Be warned, she’s a tricky specimen for an inexperienced grower – indeed, excellent weed doesn’t come for free! You’ll need to provide routine maintenance and keep a close eye on nutrients, providing plenty of TLC in order to pull in a huge final yield. Make sure her fertilizer contains plenty of iron, zinc and magnesium. Indoors, you can boost yields by scrogging, and outdoors, you’ll need a warm and sunny spot with a gentle breeze and no adverse conditions. 

With a chunky stalk and gorgeous forest green leaves, Super Silver Haze Feminized is a beautiful specimen to behold. As she matures, her leaves gradually turn a lovely golden-orange color – a fitting visual reminder of her mouth-wateringly aromatic and resinous buds.  


Whether you’re seeking an enjoyable wake-and-bake or an essential afternoon pick-up, Green Crack Feminized is simply unbeatable when you need an energy boost. This Indica/Sativa hybrid is really easy to grow – even for beginners – and is said to have a number of medicinal benefits too.

Strain info

There are two different phenotypes of Green Crack – a 65% Sativa-dominant version and a 75% Indica-dominant variety. The former is by far the most popular, and this is where the plant’s reputation for instant recharge and energizing effects comes from. The THC content varies from 15% to 20%, usually hovering around 17%. This makes for a really versatile plant that lends itself to loads of different smoking situations.
At a first sniff, you’ll notice a fruit-and-citrus aroma, with notes of freshly dug earth and a surprisingly dank twist. When lit up, the sweet and sour tang comes to the foreground, and the exhale contains sweet notes of pineapple and mango.

Growing Green Crack Fem

Even newbies can get great results from this plant – it’s a rewarding and straightforward growing experience from start to finish. Indoors, it can be grown in a closet or a windowsill, but you’ll need to keep the humidity levels relatively low to avoid issues with powdery mildew. Outdoors, you’ll need relatively stable and predictable Mediterranean-like conditions to get the job done.
Yields vary from moderate to excellent – anything up to 20 ounces of outstanding cannabis for every square meter of grow space. If planting outdoors, plan to harvest at the end of September for the best possible results.


Green Crack Feminized

Enjoyed responsibly, Northern Lights induces a sweeping mental euphoria that’s as remarkable as the aurora itself! The most famous light show on earth lends its name to one of the most well-known and well-loved cannabis strains on the planet. Here, in autoflowering form, she’s easier to grow than ever before. 

Multiple High Times Cannabis Cup Winner

Strain Info

Northern Lights is said to hail from Seattle, and can be traced back to the 70s. She worked her way across the globe, eventually reaching the Netherlands, where breeders worked their magic and in 1985 created the commercial herb we’ve all grown to know and love. She soon went on to win a variety of awards, including the top Indica Prize in the first ever High Times Cannabis Cup – an accolade she was awarded again in 1990 and 1997.

Originally a cross between two landrace strains, Thai and Afghani, Northern Lights Auto is almost pure Indica, at around 90% to 95% – so her potency and hard-hitting sedative qualities come as no surprise. The quintessential two-hit-and-quit strain, even the most seasoned tokers are advised to go steady. 

Enjoy her responsibly, and Northern Lights will induce a soaring cerebral high followed by a deep and heavy body stone and some serious munchies. It’s definitely a strain to be reserved for times when the diary is clear!

Growing Northern Lights Autoflower

At around 3 feet tall, Northern Lights Autoflower is an easy strain to grow. As well as flowering automatically, it’s naturally resilient to fungus, pests and mold, and sturdy in structure. Indoor growers favor the Sea of Green setup, with a temperature between 70° and 80°F. After seedlings appear, it’ll take about 7 or 8 weeks til harvest time, for a healthy and hefty yield of around 1.8 ounces of resinous buds per square foot.


This stuff may bear no resemblance whatsoever to a conventional wedding cake, but it’s certainly just as enjoyable! Heavy on the Indica side and boasting a whopping 27% THC, Wedding Cake Feminized is not for the faint-hearted. But for those who can handle her, she guarantees one of the most extraordinarily potent, punchy and long-lasting body stones you’ll ever experience.
 
Strain Info

This hybrid is a potent, powerful and uncompromising specimen that’s designed for no purpose other than to flatten you. Her genetics may be relatively well balanced, but the stone she provides is most definitely not!
A cross of the infamous Girl Scout Cookies and the classic dessert strain Cherry Pie, Wedding Cake is an Indica-dominant hybrid that turned out to be far more than the sum of her parts.  Her deceptively Skunky flavor is guaranteed to entice you to take a second helping, while her fragrance is a generous cocktail of terpenes, including myrcene, terpinolene, limonene, ocimene, and many others.
Just a few tokes are plenty to ensure a sledgehammer soporific stone that lasts for hours and almost always ends in a long and restful sleep. Take it easy with this one, no matter how high your tolerance, because a little bit goes a long way!

Growing Wedding Cake Feminized 

You don’t need to be a seasoned commercial cultivator to get good results, but Wedding Cake does need a little more TLC than some other plants. Humidity should be kept relatively low at all times, as she has a tendency to succumb to mold. Outdoors, she needs a sunny and stable Mediterranean-like climate to thrive. Flowering comes in at around eight weeks, after which you should be looking at about 15oz of quality high-THC cannabis for every mature plant.


Genetics: Unknown; likely Super Skunk x Chemdawg

This now-legendary plant has already made a name for itself, and it’s easy to see why. Its pungent aroma is instantly recognizable, and its sour lemon and gasoline notes combine perfectly into a surprisingly enticing toke. The invigorating buzz it provides is ideal for a morning pick-me-up or a nighttime party companion. Energizing, uplifting, and impossible to ignore!

Strain info
 
Sour Diesel’s pungent and distinct scent likely comes from the rumored Skunk influence in its genetics. If you sniff it in the bag, you’ll notice hints of kerosene with warm spice and some herbal notes, but it suddenly becomes a lot more sour once it’s lit up.
Perfect as a wake-and-bake, it’s also a great partner for nights on the town – and it’s perfect enjoyed at social occasions that require a little more energy at the end of the day. The very definition of a ‘happy high’, it’s loved by writers, artists and musicians thanks to the motivational creativity boost it provides.

Growing Sour Diesel Fem

This tall and slender Sativa-dominant strain has thin leaves and a Christmas-tree shape that looks enticingly festive once the frosty trichomes come in. At less than 5 feet tall, she works well indoors or outside – although outdoors she’s a little more difficult to work with. To really get things off to a flying start, pair hydroponics with a Sea of Green (SOG) or Screen of Green (SCROG) set-up. After around 10 weeks of flowering, you’ll be rewarded with up to 1.63 ounces per square meter! 


Sour Diesel Feminized

Blue Dream is the single best-selling strain on the commercial cannabis market in North America. Equally popular among recreational and medicinal cannabis users, this feminized and fruity beauty is fragrant, flavorful and fabulous for all occasions.


With an aroma and flavor reminiscent of fresh blueberries, Blue Dream Feminized is simply irresistible. A true California original, this stuff has long been the strain of choice across the US West Coast.


The appeal of this berry hybrid lies in her diversity and versatility. From first-timers experimenting with weed in their early days to seasoned stoners or strictly therapeutic cannabis users, Blue Dream Feminized is one of few strains to cover all bases. Somehow relaxing and energizing at the same time, this ganja can be anything you want it to be.


Engineered by combining the genetics of two equally celebrated strains – Blueberry and Haze - Blue Dream is a versatile 60% Sativa and 40% Indica hybrid. DJ Short is credited with bringing the world this superstar strain, though probably had no idea at the time just how popular it would become.


Along with intensifying the fabulous fragrances and flavors of her parent strains, this Sativa-dominant specimen also routinely tests for a THC content in excess of 25%. Though somehow, she’s not the kind of strain that takes you off-guard and knocks you off your feet – even if your THC tolerance isn’t huge. 

Blue Dream Feminized

This hulking great specimen of a strain has been doing her thing for some time now, yet continues to top the table as one of the most monstrous hybrids ever concocted.

Like Marvel’s Incredible Hulk, the Bruce Banner Feminized strain is green, grows to a towering height and has enough strength to blast you into the middle of next week. However seasoned you consider yourself to be, 27% THC is more than most can handle.

What’s interesting is how this cannabis combines frankly terrifying potency with a delicate, aromatic and downright delicious flavor profile.

You’d expect these buds to reek of nothing but old-school Skunk and head-spinning dankness, but it’s actually more of a floral and fruity affair. One that belies the potency and intensity of the high to follow, which never fails to catch novice smokers off guard.

The genetic composition of Bruce Banner Feminized is relatively well balanced, coming in at around 60% Sativa and 40% Indica genetics. This is pretty much right on the money as far as the high goes, which propels you into a world of pure fantasy before delivering one hell of a body blow. All of which adds up to a hugely enjoyable and versatile strain, with a long list of potential therapeutic applications.

If all that wasn’t enough, this herb has the potential to be as generous in terms of yields as she is in potency. This being the feminized version, problematic male plants are eliminated from the equation.

Bruce Banner Fem needs some serious headspace to reach her full potential, but is nonetheless capable of producing more than 30oz of weed for every square meter of grow space. Which is (for most people at least) way more than you’ll be needing for quite some time to come.

Bruce Banner Feminized

Genetics: Gorilla Glue #4 x unknown Ruderalis
 
An excellent example of cross breeding done right, Gorilla Glue #4 Autoflower is a mighty Indica-Ruderalis that grows fast and thick with minimum effort, boasting 22% – 25% THC to boot. The flavor is something of an acquired taste, with hints of coffee, ammonia, pine and diesel, but the full on mind-and-body buzz is worth the price of admission alone. An evening delight if ever there was one!

- First place winner in the High Times Jamaican World Cup
 
Strain info

As with other similar autoflowering strains, Gorilla Glue #4 Auto is small and stocky in stature, but mighty and strong in temperament – so much so that even a beginner can manage a decent yield of sticky trichomes and dense buds with minimum maintenance. 

Once you’ve taken a toke or two, instant positivity is the first thing you’ll notice. It starts with a soaring cerebral buzz, but it doesn’t take long for a sedating high of powerful proportions to begin its descent! It’s said to be great for medicinal users seeking reprieve from physical discomforts such as arthritis, migraines and PMS, and almost always leads to a long and relaxing slumber.

Growing Gorilla Glue #4 Autoflower 

Despite the heavy foliage, pendulous buds and enormous apical cola, this strong and sturdy specimen needs no additional support. Give it 18 hours or more of light per day and it’ll pretty much grow itself – and you can even give it a full 24 hours as long as you can accommodate the extra heat (and pay the bills!). Keep the temperature between 20° and 26°C and the relative humidity around 40% to 50%. It’s usually ready for harvesting after 9 to 10 weeks – at which point you’ll get anything from 400 – 600 grams of forest green nugs covered in frosty white crystal trichomes, ready to glue up your scissors!


Gorilla Glue #4 Autoflower

The original and some would say the best, Granddaddy Purple takes all that’s fantastic about Purple strains to an entirely new level. Guaranteeing the ultimate all-round sensory experience, this bud beauty is as mesmerizing to look at as she is to smoke.


Also stylized as Grand Daddy Purple, this hybrid is one of the most celebrated and popular purple strains of all time. Famed for incredible looks, a fabulous fruity flavor and face-melting high, this mauve marijuana has been reinvented and recreated thousands of times over the years. Though it has to be said that nothing comes close to the original.


Strutting her stuff proudly for a good two decades now, Granddaddy Purple Feminized continues to set the bar for pretty much all other purple strains going. Averaging somewhere in the region of 20% THC, this Indica-heavy hybrid is potent enough to have you flat on your back indefinitely.


Officially unleashed in 2003, this strain first appeared in the San Francisco Bay Area before going global. The legendary Ken Estes is famed for bringing this mighty hybrid to the masses, which immediately caught the attention of cannabis connoisseurs for her extraordinary looks (among other standout qualities, of course).


With a genetic composition of approximately 80% Indica and 20% Sativa genetics, these buds are near-narcotic in their impact on the body. If you’re simply looking for something that gives you no choice but to relax and unwind, this one’s for you. Likewise, if you’re all about fragrance and flavor, there’s almost nothing else out there that compares to Granddaddy Purple Feminized.


While not the easiest strain to grow, cultivators’ efforts consistently feel more than justified - especially considering what you get back in return. Sticking with the feminized version will help you keep problematic male plants out of the equation, unless you’re working on your own hybrids.
