highest yielding strain in the world

Highest Yielding Indoor Strains in 2020

Ready to rock 2020 with some monster harvests? If you’re looking for bigger yields this year, you’re in great company. Cannabis growers are always looking to boost the size of a harvest while enhancing the quality of the crop. This year it’s as important as ever to get more out of every bud, so here is our comprehensive list of the best strains of 2020 in terms of bigger yields and ease of growing.

Planning for Maximum Yield: The Basics

Yield is just another word for harvest in the cannabis grower vertical. For indoor growers, yield tends to be measured by square meter of growing space—how much product you can get out of every square meter of plant in that space.

There are a host of factors that can impact yield. This is the main reason why estimating yield is imprecise. Roughly, however, for most indoor cannabis strains under good growing conditions today, you can expect at least 14 ounces of product per square meter as a baseline estimate.

From there, of course, it might go way up, depending on the strain and the quality of the seeds. And since yield is so crucial to most home growers, that quality and the potency of the cannabis seeds definitely matter.

No matter how green your thumb is or how much time you spend on lighting or trimming your garden, to a large extent, the yield is controlled by the genetics of the plant. In this guide, we offer up the ten best, easy-to-grow cannabis strains to grow this year based on high yield.

Let’s face it—there’s never been a better time to start. Legalization is becoming more and more mainstream. There are over 30 medical marijuana states in the US already.

And right now, it’s the tail end of a planting season and warm weather is here, no matter where you are. It’s time to choose your highest yielding strains for this year’s crop—and we have some ideas.

As we evaluated the strains that are out there right now, we considered lots of factors. Many new growers especially are hoping for the most budget friendly strain, but although cost is important, this isn’t always the smartest move if you really want to end up with a harvest. You also have to consider whether your chosen strain is suitable for medical use, its estimated flowering period, the probable THC content, and other factors.

It’s never exactly cheap to grow medical grade cannabis, but selecting high potency, high quality seeds to scale up yields is one way to reduce costs. Fortunately, as we are currently living through a sort of cannabis breeding renaissance, there are many excellent, high-yield cultivars out there that produce dense, sticky buds frosty with trichomes.

Here we’ve narrowed it down to 10 of the highest yielding strains. We aimed for the sweetest yield-to-effort ratio for new growers, and tried to include indicas, sativas, and hybrids.

Each of these strains is reliable, and the linked seed bank will not let you down. Follow germination instructions to harvest an impressive yield, and remember that autoflowering versions of seeds, although they will probably outperform other strains will still produce less than photoperiod versions of the same strains.

So here they are, the best high yielding strains for 2020:

Big Bud

If you’re looking for a certain cash crop that’s also an excellent strain for breeding, Big Bud is a great choice. This high yield cannabis cultivar has won multiple awards. This child of love and science was brewed by Sensi Seeds from Afghani, Northern Lights, and Skunk #1 and genetics.

Big Bud cannabis plants are responsive, remaining at medium height when grown indoors. Yet these huge buds, the inspiration for the strain’s name, truly pack on the extra weight during flowering. In fact the one downside to growing Big Bud is that these plants will be heavy enough to collapse under their own weight if you don’t support them.

Since the 1980s, Big Bud has basically been the old school high yield strain. Especially when you consider how compact this plant is, 600g/m2 is a pretty impressive yield.

Better still, this is a great choice for breeders. These genetics have gone on to produce super stars like Granddaddy Purple, which have all the flavor and stoney effects of a purple strain or something like OG Kush with the high yields of the Big Bud genetics.

Speaking of genetics, another reason this cultivar is so friendly to growers is that it is very resistant to diseases, molds, and pests. Even for noobs, basic care will result in huge, heavy nugs on these plants.

Benefits:

  • Produces seriously huge buds
  • Classic indica effects
  • Delicious, unique, fruity aromas and flavors
  • High THC levels
  • Difficulty: easy
  • Type: photoperiod
  • Sativa/Indica: 40% / 60%
  • Seed Sex: feminized
  • Average plant height: 36″-60″
  • Ready for harvest in: 49 to 77 days
  • Approximate indoor yield: up to 25 ounces/3 square feet
  • Taste and aroma: sweet, lemon, fruity, grape, peppery, spicy, earthy
  • Effects: euphoric, energetic, happy uplifted, and relaxed
  • Medical treatment: stress, pain including chronic pain, headaches including migraines, PTSD, insomnia, and eating disorders
  • THC content up to 20%
  • CBD content up to 0.1%

Blue Dream

Blue Dream—the sometimes maddeningly popular offspring of the famous indica strain Blueberry and sativa powerhouse Super Silver Haze. It’s not just an amazing medical marijuana strain or some basic recreational strain that accidentally got popular.

Blue Dream hits that sweet spot with a powerful, potent, sativa dominant set of effects. This relaxing but uplifting hybrid delivers peppery, berry scented aromas and a lasting buzz.

The true legend status of this strain comes in with the way you get to slide into a gentle euphoria and then settle into a full-body relaxation. Perfect for both experienced users and newbies, it’s a great all day strain.

Just like the rest of the experience, the effects are balanced, with deep body effects and a nice cerebral high that’s not too much. The end result is relaxing for mind and body, but not sedating.

Blue Dream is also a grower’s favorite for its massive yields. It is happiest growing indoors, in that it can be sensitive to fluctuations in temperature and weather. Make sure you’ve got space for it, though, because it is a tall plant, and for best results prepare to top your crop as it gets taller. This strain does respond well to SCROG and SOG techniques.

Blue Dream is also an excellent breeder, and you’re likely to get plenty of interest in any progeny from this strain. Still, especially for a sativa-dominant strain, this is a truly easy-to-grow option. One of the best, even with less effort, with a high yield within 10 weeks.

Benefits:

  • Hugely popular strain
  • Great resistance to mildew and pests
  • High yields
  • Balanced effects
  • Difficulty: easy
  • Type: photoperiod
  • Sativa/Indica: 60% / 40%
  • Seed sex: feminized
  • Average plant height: 48″-72″
  • Ready for harvest in: 63 to 70 days
  • Approximate indoor yield: up to 21 ounces/3 square feet
  • Taste and aroma: berry, blueberry, fruity, herbal, mangoes, sharp earthy, sweet, vanilla
  • Effects: creative, euphoric, happy, relaxed, uplifted
  • Medical treatment: depression, fatigue, inflammation, headaches including migraines, menstrual cramps, pain, PTSD, stress
  • THC content: up to 24%
  • CBD content: up to 2%

Cheese Quake

One of the most interesting things about Cheese Quake is its amazing genetic history. Although its parents are both pretty stoney indica strains—Querkle and Cheese—this exceptional hybrid is very well-balanced, with an energizing form of relaxation suitable for almost any kind of activity.

In fact, one of the things consumers like most about Cheese Quake is the way the mental high and the body buzz balance out so well. The head effects hit first as stress melts away, and then the pain relief sets in. For many users, this is a fine social strain, although maybe not something you’re going to use to climb Mount Everest!

Like most of the cheese family, the aroma of this one is surprising. Yes, some definite sour undertones that are pungent, but not an actual cheesy smell. It’s more of an umami, a savory flavor with hints of fruity, sweet grape.

Cheese Quake is a decently potent cultivar, usually weighing in around 18% THC. It also may have CBD content of up to 1.5%, which can add pain relief but may reduce its psychoactive effects. This makes for a manageable experience and lots of relaxation without the couch-lock and lost time.

Better still from a grower’s standpoint, Cheese Quake is very forgiving and easy to grow. Better grown indoors, you lose nothing taking these marijuana seeds inside as these plants really spread and grow as fast as you want. As long as you top off early, you’ll stay in great shape with large, heavy proportions and an amazing yield.

Benefits:

  • Huge, heavy buds
  • Very fast-growing roots
  • Excellent pain relief qualities
  • Nice, balanced high
  • Difficulty: easy
  • Type: photoperiod

  • Seed Sex: feminized
  • Average plant height: 36″-72″
  • Ready for harvest in: 56 to 63 days
  • Approximate indoor yield: up to 18 ounces/3 square feet
  • Taste and aroma: cheese, grape, pungent, sour, sweet
  • Effects: euphoric, focused, happy, relaxed, uplifted
  • Medical treatment: anxiety, depression, fibromyalgia, insomnia, muscle relaxer, pain, rheumatoid arthritis, stress
  • THC content: up to 18%
  • CBD content: up to 1.5%

Chocolope

For one of the absolute easiest sativa strains to grow, try Chocolope. This great strain crosses Cannalope Haze and Chocolate Thai. It’s a fabulous, energetic daytime strain for getting things done and just feeling some joy. In fact, if you want the gorgeous, happy energy of an Amnesia Haze or Sour Diesel but don’t want to deal with a tough grow? Chocolope is your plant.

Need that cannabis strain that’s your morning coffee to get you going and then some? Want to relax, get motivated, and feel happy without getting the munchies or couch-lock? Gearing up to create something truly inspired, but you need to push yourself into getting started? Need to treat sour mood or minor pain without losing your edge? Chocolope is ideal.

Unlike most sativa and even sativa hybrid strains, this one really is an easy grow. All you really need is a tall, well-ventilated space, because its one weakness is mildews and molds. Oh—and these plants get tall. Up to 87 inches! So yes, you will need some clearance for these beauties, but they will reward you.

Benefits:

  • Happiest mood in town
  • Very easy sativa grow
  • Delicious flavor
  • Difficulty: very easy
  • Type: auto-flowering and photoperiod

  • Effects: happy, euphoria, uplifted, enhanced mood, creative, energetic
  • Medical treatment: anxiety, PTSD, and Bipolar Disorder
  • THC content: up to 21%
  • CBD content: up to 1.5%

Critical Mass

Critical Mass is a grower’s friend and a medical marijuana patient’s dream, making it one of our top ten best strains to grow right now. Descended from Skunk #1 and Afghani, this indica-dominant strain is ideal for the evening, with up to 22% THC and at least 1% CBD for additional mellow pain relief.

But if we’re being perfectly honest, Critical Mass gets even more fans from the grower side. Commercial grows use this mass production cultivar specifically because of its very high yields and ease of cloning.

Cultivated properly, Critical Mass yield even more when grown indoors, because it is prone to mold issues. Good spacing and ventilation is all you need to deal with this, and that’s the only trouble you’re likely to run into—a great strain even for beginners.

The fun part with Critical Mass comes closer to harvest time. The buds are extremely dense and heavy, and in many cases growers must use stakes to support their plants. It’s a little bit of effort for a huge payoff, because you’re literally helping the plants support that gold that you’re waiting to harvest.

Benefits:

  • Exceptional indoor yield
  • Short flowering time
  • Medical patient favorite
  • Relatively high CBD content
  • Difficulty: easy
  • Type: photoperiod

  • CBD content: up to 1%

Gold Leaf

For all of those who love instant gratification: Gold Leaf is your strain. It was bred specifically to deliver an instant hit of giggly joy, and that’s what it does.

The other breeding goal behind this strain was intended for the grower: reliable, heavy yields. For both of these reasons, Gold Leaf makes this list—and its high THC levels are a huge bonus too, let’s face it.

So, this is a fantastic option for a first time grower looking to have a 7-foot-tall plant seemingly spring out of nowhere, thanks to some sativa genetics. Use Sea of Green techniques to keep a lid on height if you like. And, with a little cropping and pruning, you’ll soon be seeing big yields of up to 23 ounces per square meter—pretty awesome.

Benefits:

  • Super happy, giggly strain
  • Reliable, big yields
  • Difficulty: easy to moderate
  • Type: photoperiod
  • Sativa/Indica: 40% / 60%
  • Seed Sex: feminized

Gorilla Glue

Balanced hybrid Gorilla Glue is a popular standby in dispensaries and personal stashes across the US. Its family history includes Chocolate Diesel, Chem’s Sister, and Sour Dubb.

Gorilla Glue may be famous for being a high-THC knockout, but it’s also a super yielder. This is even more striking when you consider the plant is reasonably compact—especially inside. GG is also highly resistant to diseases, mold, and pests, so there is less maintenance involved with the grow. In fact, you set up your grow lights and go–no fuss, no muss with Gorilla Glue.

  • This is the couchlock everyone wants!
  • Seriously high THC levels
  • Difficulty: easy
  • Type: photoperiod

  • Approximate indoor yield: up to 21 ounces/3 square feet
  • Taste and aroma: cheese, earthy, pine, pungent, sour, sweet
  • Effects: euphoric, happy, relaxed, sleepy, uplifted
  • Medical treatment: anxiety, depression, insomnia, lack of appetite, pain, stress
  • THC content: up to 28%
  • CBD content: low

Why GSC? Well, you just can’t go anywhere these days without running into a million cookies, cake, and related strains—for good reason. This is just a powerhouse line from a grower’s perspective. With a high yield to boot, this has to be among the best strains to be growing in 2020.

Patients and recreational consumers alike love the GSC strain and its many offshoots. Delivering full body symptom relief and a gentle yet powerful suite of cerebral effects, this California cultivar earned its many awards.

For beginner growers GSC is a great strain, despite its extreme yields and high THC concentrations. This is because the GSC cannabis seeds are very resistant to infestations of mold and pests. So if you’re just learning how to grow or you just can’t devote all your time to it, this is a great choice.

Benefits:

  • So many new strains to breed, so little time

  • THC content: up to 21%
  • CBD content: less than 1%

Northern Lights

The jewel of the Pacific Northwest, Northern Lights is an easy, forgiving grower in both hydroponics and soil. This parent of many a great hybrid strain has is an ideal indoor crop with a pleasant and subtle aroma that might be particularly appealing for stealth growing operations.

[Not that we would tell you to break the law. We would not. Never break the law. Be cool, follow the rules.]

Named for the extraordinary color the buds take on during flowering—a treat for growers in itself—Northern Lights is the kind of famous strain that provides both name recognition and an exceptional, stoney body high for your arsenal.

Best of all, as a strain, Northern Lights is about as straightforward and easy to grow as it gets. This plant is compact and resists trouble from disease and pests. It will flower with less light, usually in about 7 to 9 weeks is ideal. You will love the psychedelic looks of these nugs and frosty trichomes!

Benefits:

  • Classic strain with name recognition
  • Massive yields indoors
  • Relaxed, mellow body high
  • Difficulty: easy
  • Type: auto-flowering and photoperiod
  • Sativa/Indica: 10% / 90%

White Widow

White Widow is going to be on just about any list like this that’s worth anything, because it is a world champion resin producer, hands down. It’s also a fantastically stable, resilient strain, and a delightful smoke

This indica-dominant hybrid was born on the Amsterdam coffee-shop circuit decades ago after Dutch breeders crossed two landrace strains: a South Indian Indica with a South American Sativa. The result was the fat, resinous buds that White Widow is now famous for. With a THC content of up to 25%, there’s a reason people are after that crystallized resin.

Now, as to yield: it’s a winner. Indoors in a flowering time of just 8 to 9 weeks, White Widow can yield up to 18 ounces per square meter. You’ll be surprised that the taste of White Widow leans toward the earthy when you see how sugar frosted these buds look.

White Widow thrives just about anywhere, but although it resists pests and mold, it will produce the highest, most stable yields inside. Not a total knockout, most users report they can consume White Widow any time of day and remain productive, avoiding couchlock.

If you do any research on medical marijuana strains you’ll find White Widow is sought after for menstrual cramps, fibromyalgia, migraines, and other top complaints. It’s also a social, chilled experience for recreational users, making it a popular choice among consumers.

Benefits:

Tips for Boosting Yields

The best thing you can do to boost your yield? Select the best high-yield strains like these. You get off to the best start with the best genetics, and not all cultivars are created equal.

Still, there are best practices for higher yields, and following them can help. Here is a quick list of tips and tricks to boost your harvest:

Growing medium

Hydroponic or soil? For the maximum yield, hydroponic growing is optimal, although the skill set can be daunting and the startup costs can be high. Composing your own organic soil medium is the excellent alternative for increasing yields, because it enables you to boost growth by controlling the ratios of coco, perlite, soil, and other mediums.

Lighting

Space high intensity lights evenly to maximize coverage and create the right environment for growing. Maintain sufficient light during the veg stage, and then increase light intensity during flowering to raise overall yields.

Container size

As plant roots outgrow their containers, it gets too difficult for them to effectively take in the nutrients and water they need. As your plants grow, be sure you’re increasing your pot size, too.

Nutrients

Your choice of nutrients can maximize cannabis yields, as well. Time the process so your plants get the right nutrients at the right time; so-called “all-in-one” solutions are never ideal. Instead, focus on a fertilizer at the veg stage. Typically, a balanced NPK mix of NPK works well.

Training techniques

Fimming, pruning, super cropping, and topping are all training techniques that help expose bud sites to maximum light with minimal stress. Proper support of your plants’ stalks with stakes or trellises can also help develop bigger, stronger buds.

Harvest timing

Harvesting too soon can mean losing as much as one-quarter of your hard-fought crop. That’s because the final few weeks of the growing cycle is when those buds really do the most work. For the highest yields, be patient, watch for all of the signs, and check the proper harvest time for the strain.

Final Thoughts

We hope this list of best strains to grow in 2020 has been useful to you. The strains on this list are all easy to grow and very high yielders. In some cases you might need some minimal staking or pruning (which we told you about), but this is a minimum effort, maximum output list.

As you make your choices on what to grow in 2020, keep in mind that experience and skill affects yields when growing any crops of any sort. So do practical considerations like space, growing medium, light, and even things like local laws and regulations.

But if you’re going to grow, it just makes sense to invest in a strain that you know will deliver high yields—no matter whether you’re selling, sharing, or consuming your harvest all yourself. Enjoy your growing and harvesting.

The highest yielding indoor strains that should consider growing in 2020. Find out which strains made our "best of" list in this interesting cannabis category.

Top 10 Highest Yielding

We know you want a mountainous pile of marijuana come harvest. Great big trophy colas and nothing but the biggest dankest buds will do. How do we know this? Because we are cannabis growers too and each and every one of us dreams of one day pulling down the “Big Dirty”.

In other words, we all lust after that bumper harvest to beat all harvests. It’s time to crop a personal best. Keep reading to find out which cannabis strains can make it a reality.

1. Critical Mass

The name says it all. Top of the list has got to be Critical Mass. A refined blend of Afghani and Skunk #1 genetics Critical Mass is a pedigree producer. Heavy indica in every sense of the word. Critical Mass is a fast flowering organic bud factory. Hers is a pungent earthy smoke with a long lasting relaxing physical happy high.

Indoors due to her compact structure and rapid bloom time of just 50 days, give or take, Critical Mass is ideally suited to SOG cultivation. Similarly, outdoors in a warm southern climate Critical Mass can develop into a real ganja bush. Minimal fertiliser and hands on grower maintenance is required to crop up to 700g/m².

Experienced outdoor southern growers report yields up to 1kg per plant. However, these huge buds are susceptible to mold. High humidity is to be avoided like the plague.

2. Critical Kush

Combining the red hot US favourite OG Kush with the uber productive Critical endows the progeny, Critical Kush with a blend of amazing attributes. Not least her amazing hybrid vigour. Dank chunky Kush nuggs with a rich pine flavour in large quantities is what you get if you treat Critical Kush right.

Flowering is fast and furious with a heavy harvest ready in about 50-60 days. Plants resemble Critical in structure keeping a low profile, branching well and developing a huge main cola. The Kush genetics give buds a dense frosty attractive appearance and a powerful sedative effect.THC can exceed 20%+ making Critical Kush a genuine case of a strain that requires more experience to toke than grow.

3. Industrial Plant

Industrial Plant is probably the highest yielding version of the legendary Northern Lights. Bred from Afghani and Thai parents this particular incarnation of Northern Lights was developed for maximum yield. Industrial Plant is a classic old school spicy peppery chill out smoke. Not devastatingly potent more of a relaxing happy buzz.

Expect long running tight trophy colas in as little as 45-50 days of bloom.Best of all ripe buds and colas require minimal trimming. The flower to leaf ratio can be insane. Indoors 1m tall plants are perfect for a SOG. Outdoors Industrial Plant can climb to 2m+. Scale tipping harvests in excess of 1kg per are not unheard of. Highly recommended for beginner growers.

4. Monster

Many strains are described as a “monster” this one is the real deal. Monster is a cross of G13 Hashplant and an exotic South American mostly sativa hybrid. This space hungry beast is a huge producer of high-grade head stash. Reminiscent of old school uplifting skunks with a pleasant euphoric effect and powerful odour.

Monster is very attractive to indoor and outdoor growers as she is a proven enormous producer of mold resistant bud. Unfortunately Monster will require plenty of hands on attention to deliver the heaviest harvest. Indoors a ScrOG is a virtual necessity to tame and support those Monster colas.

Outdoors she can stretch to 4m in height. Almost unbelievable yields have been anecdotally reported of close to 3kg per plant by pro Mediterranean ganja farmers. Perhaps the only thing easily managed is her relatively short 9-10 week flowering period.

5. Big Bud

Big Bud is the original Green Bud Machine. The modern representation has been backcrossed to her original Afghan roots to further refine the classic Afghan and Skunk #1 blend. Vintage earthy hash and skunk aroma combined with an expansive full bodied flavour give these oversized buds genuine character. Delivering a relaxed body stoned effect. Very chill smoke.

Easy to grow and forgiving to novice growers Big Bud is a great introduction to high yield cannabis cultivation. Long running thick main colas and chunky side branches will require support during 60 days flowering. Plants will stay about 1m tall and still exceed 600g/m². Alternatively outdoors in large containers with Big Bud, the sky is the limit. 2m+ tall trees can hit 1kg yields.

6. Sweet Moby

Sweet Moby is a marijuana leviathan. This sticky green giant is a beastly mix of Haze and White Widow genetics. A two stage head-body effect is to be expected. Initially, a clear cerebral buzz takes you up. Followed by a calming physical wave. A mix of earthy, pine and wood scents will perfume the air when you blaze this chunky resinous stash. Sweet Moby is a smooth smoke and a real mood booster.

Indoor growers are advised to prune and train early for maximum yield as Sweet Moby can stretch to 2m tall. Outdoors she will grow to cloud eater proportions, perhaps as tall as 3m in warmer climates. 600g/m² is about the average indoor yield with a well maintained ScrOG and typical 600w lamp or LED equivalent. While experienced outdoor growers down south can pull down over 600g per plant. Flowering will take 9-10 weeks and take care to keep humidity low in the final weeks.

7. Big Foot

Big Foot is something of a cannabis cryptid. Make no mistake she is 100% real and we’ve got evidence to prove it. But unfortunately, nobody but the breeders knows the exact origin of this almost perfectly balanced 50-50 indica-sativa hybrid. Fruity skunk aroma and sweet flavours with a hint of grape make Big Foot a real treat for the palate. A jolly green smoke with a long lasting stoned sensation.

Indoors or outdoors in sunny weather, LST is highly recommended to keep Big Foot from stretching too tall during bloom. She can easily exceed 2m in height without training. Flowering is fast paced at 7-9 weeks total. Shading fan leaves will require pruning to allow greater light penetration to those long running dense colas. Yields of 500-600g/m² are typical indoors while per plant yields of the equivalent can be harvested outdoors in warmer climates.

8. Brian Berry Cough

Brian Berry Cough is a gourmet indica-sativa hybrid named after an ALS patient. This amazing strain has Strawberry Cough, Romulan and Cindy 99 genetics coursing through her calyxes. Two phenotypes present, one sweet and one sour. So there’s towering flower tops to suit every taste.

Early training goes a long way toward controlling mature plant height, which can exceed 2m indoors and possibly 3m+ outdoors in a hot dry climate. Yields can be incredibly high in just 8-9 weeks of flowering. These baseball bat buds will launch your head into outer space before gently taking you to dreamland.

9. Power Plant

Power Plant is the South African sativa hybrid that has gained an international reputation for high production of exotic head stash. For 20 years Power Plant has been the hardy reliable head stash strain of choice for commercial cultivators the world over. When she burst onto the scene in 1997 nobody had seen such amazing oversized sativa buds.

Even by today’s standards, a sativa that can flower in 8 weeks and stay below 2m indoors or outdoors is amazing. Now factor in that this robust beast can produce up to 600g/m² indoors and 500-600g per plant outdoors in the hottest conditions. Power Plant is earthy and loud. Plus she will send your head to the clouds with just a few tokes from a spliff.

10. Purple Chem

As usual, we have saved something special for our final pick of heavyweight cannabis strains. We don’t do filler folks it’s all killer strains from the first to the last. Without further ado, our final pick for this the top 10 high yielding cannabis strain countdown is a rare monstrous cannabeast from the US called Purple Chem.

This beautiful purple producer is a blend of pedigree Chemdawg and pre-98 Bubba Kush genetics. Purple Chem is or rather was the best-kept secret of pro growers. Few strains can match Purple Chems devastating combination of killer looks, fire potency and massive yields. Indoors a ScrOG is recommended to organise the dank field of lush lavender colas and keep height under 2m. 500-700g/m² of dank purple Couchlocking stash is the reward.

Outdoors 2m+ purple bud laden marijuana trees are a magnificent sight to behold in warm climate. A sun kissed fat purple harvest in the region of 500g+ per plant could be waiting for you come Croptober with Purple Chem.

Every cannabis strain featured in this top 10 countdown of heavy yielders could potentially bring you the biggest harvest of your life.
