Here Are 4 Cannabis Strains That Produce Massive Yields

Lighting, nutrients and correct watering regime all help to maximise yields. However, selecting the right strain can make the differences between mediocre and massive harvests. Explore four biggest producers of 2020.

Take your cannabis yields to another level with our four top strains for 2020.

Nothing beats harvesting sticky aromatic buds at the end of a grow. At that moment, all of your hard work and dedication manifests into picking the fruits of your labour. The more buds you snip from their branches, the higher the level of satisfaction.

Full-spectrum nutrients, powerful lights and perfect humidity all contribute towards better yields. However, the genetic potential of each plant also determines the size of the harvest. Some varieties are small, stealthy, and provide less productive canopies. In contrast, breeders have developed highly productive cultivars that can keep your stash jars full all year round.

Below, you’ll discover four of the highest yielding strains of 2020. All of these cultivars boast an abundance of bud sites and respond exceptionally well to training techniques. Before we take a look, let’s cover some common questions about improving cannabis yields.

Sativas or Indicas—Which Yield More?

In general, sativa-dominant cannabis strains tend to provide heavier yields. These varieties reach much taller heights—sometimes resembling small trees—and produce bigger canopies, with more bud sites.

How Do Growers Achieve Large Yields?

Genetics underpin the true potential of every strain. After selecting a cultivar that promises to produce large yields, growers need to ensure they provide powerful lighting, nutrient-rich soil, and adequate amounts of water. Training techniques can also significantly improve output.

How Is Cannabis Yield Measured?

The same strain can produce dramatically different results depending on pot size, nutrient availability and the growing environment. The estimated yield of each cannabis strain derives from an average calculated from different growers.

How Does Veg Time Affect Yields?

Plants aim to grow as big as possible in their vegetative phase. Bigger plants possess more branches and bud sites, potentially meaning bigger yields. Conditions permitting, the longer your veg time, the more likely you’ll have a large harvest.

The Four Biggest Yielding Cannabis Strains of 2020

Without further ado, here are our top cannabis strain selections for 2020, for those wanting high-yielding plants that maximise productivity and output.

Green Gelato

Green Gelato produces compact and nugget-like buds. Although her flowers are relatively small, she pumps them out in massive quantities. This highly productive strain features 55% indica and 45% sativa genetics. Despite that indica-dominance, she still produces yields that far exceed some pure sativa varieties.

Our breeders at Royal Queen Seeds developed this strain with yield in mind. After some experimentation, they settled on parent strains Sunset Sherbet and Thin Mint Girl Scout Cookies to complete the task at hand. After several generations of crosses, they landed on a stable phenotype that churned out large harvests every single time.

Green Gelato consistently delivers impressive results, both indoors and outdoors. Indoor plants reach a medium height of 80–120cm and do well even in small grow tents. Prepare to harvest a rewarding yield of up to 700g/m² after a flowering time of 8–10 weeks.

Outdoor plants can reach up to 200cm when grown in large containers and raised beds. These tall plants are capable of producing up to 800g per plant. We recommend using stakes to prevent her bountiful branches from buckling. These plants will mature just before the end of the season, during early October.

Her aesthetic flowers boast shades of dark green, deep purple, and orange. These resinous blossoms feature a massive THC content of 27% and a medley of sweet, citrusy, and earthy terpenes. Prepare for a stimulating, energetic, and long-lasting experience.

Amnesia Haze

Amnesia Haze: a name known all over the cannabis world. Chances are you’ve seen this strain displayed on the shelves in cannabis dispensaries and Dutch coffeeshops. Smokers from all generations continuously seek out this cultivar for its motivating high and delicious flavours. However, she rose to stardom also thanks to her reliable productivity.

Haze genetics came to life on the West Coast of the United States—a renown breeding hot spot. After they reached the European cannabis mecca, Holland, breeders tinkered with these legendary strains. Eventually, Amnesia Haze emerged as a promising hybrid. She features 70% sativa genetics and a tall and majestic morphology.

Indoor plants peak at 140cm, although training techniques, such as LST can keep them closer to the ground, at around 80cm. Under good quality lights and with a solid feeding regimen, plants will produce up to 650g/m² after a flowering time of 10–11 weeks. Outdoor plants can tower at the height of 210cm and produce a huge yield of 700g per plant, ready to crop during late October.

Amnesia Haze boasts tall and thick buds, decorated with protruding sugar leaves and light orange pistils. These tantalising buds exude plenty of resin with a 22% THC content and sweet and fruity terpenes. Her cerebral high makes a great wake and bake option.

This mighty sativa will plunge you into the mindset of a shogun—crystal clear cognition, rational and philosophical thinking, and unrivalled motivation. Shogun ticks all of the boxes of a truly great cannabis variety. She boasts high THC levels, incredible taste, and a yield that will keep you very busy come harvest time.

Our expert breeders developed this cultivar using two legendary cannabis varieties: Amnesia Haze and Gorilla Glue 4. Both of these strains are prized for their powerful effects and huge output. Shogun inherited all of their sought-after traits and emerged with 70% sativa and 30% indica genetics.

She grows tall and proud, with a vast canopy loaded with glistening flowers. Indoor plants peak at 140cm and are suited to large grow tents with strong lighting. With her basic needs met, she’ll easily produce 600g/m² after a flowering time of 9–11 weeks. Grown outdoors, she’ll surge to a height of 190cm and pump out up to 750g per plant by the end of October.

Skunk XL

It doesn’t take a genius to realise where Skunk XL got her name from. Simply take this strain to the end of her grow cycle to find out. This fascinating spin on Skunk genetics combines the sensations of the original strain with enhanced yields.

Skunk genetics descend from an international mix of landrace strains—Colombian, Mexican, and Afghan—and serve as building blocks to hundreds of modern cultivars. Our talented breeders crossed them with Afghan genetics to ramp up the productivity of this quintessential sativa. The progeny emerged with a perfectly even split of 50% sativa and 50% indica genetics.

Although her yields tell a different story, Skunk XL maintains a relevantly small size. Indoor plants reach 60–100cm and can be grown in small grow tents and boxes to keep things on the down-low. They’ll throw out an impressive up to 650g/m² after a brief flowering time of 7–8 weeks. Outdoor specimens grow to taller heights of 160–200cm and produce up to 675g/plant, ready for harvest in October.

Skunk XL’s balanced genetic profile exerts a high that relaxes the body while brightening up the mind. THC levels of 17% and medium quantities of CBD keep things mellow and easy to handle. Potent flavours of sweetness and earthiness make every hit a treat.

Choosing the right genetics can help growers obtain the biggest yields possible. Discover the four highest yielding strains of 2020 and keep your stash full.

1. Big Bud

Big Bud is a strain of weed which, as its name suggests, produces fatty buds. But it’s not the only quality that has made this cannabis genetics famous since it comes from a lineage of champions. The strain is also the parent of one of the most famous varieties of today, Critical, one of the most highly prized herbs in Europe.

It is a very easy-to-grow strain, it has a hybrid vigour that allows it to withstand many of the situations that cause stress to other plants. Its morphology is of hybrid Sativa tendency, with not very thick stems, the distance between the nodes is rather broad, the rapid development and the leaves of medium leaflets pulling at end.

Its Indica genetics can be seen in the flowering phase when it develops of extraordinary size and fairly quick maturation time.

These cannabis seeds are among the most recommended for people who are starting their journey in growing cannabis. Its hybrid vigour gives it such strength that it can tolerate beginners’ mistakes. It adapts perfectly to the SOG technique and the SCROG method and it should be noted that the Big Bud variety generates an extreme odour when grown indoors, so we recommend the use of carbon filters and extractor fans.

Big Bud also has very powerful effects, starting with a stimulating and almost exclusively cerebral hit. However, after a while, you’ll notice an increasingly strong relaxation of the body, inviting you to lie on the sofa. Don’t worry though, Big Bud is not a weed that will knock you out too much though; it can be consumed daily in moderation, especially if you have a certain tolerance for cannabis.

Power Plant is a strain that lives up to its name and delivers in terms of both strength and yield. The plant delivers very good results if you look after it properly and is full of flavour and abundance.

The alliance between Indica and Sativa is revealed in its taste, a fresh pine mixed with aromas of coffee with sweet and fruity notes that give it an original and unusual taste. The haze is thick and you can taste it in your mouth during the exhale.

Effects can best be described as a powerful Indica high which increases the physical sensations which gently fade into relaxation. Power Plant is a good strain to relieve pain while making you smile. Perfect for winter, it allows you to keep busy at home with fruity flavours reminiscent of summer.

Power Plant grows well indoors thanks to its reasonable maturation time and its XXL yield. It is the ideal choice for novices and experts alike.

3. Super Silver Haze

Since two brothers started growing Sativa cannabis plants around the world in the 1970s, cannabis smokers have been truly grateful for the existence of a strain called Haze. Originally, it was the culminating variety after years of selecting thousands of seeds from Colombia, Mexico, Thailand and South India. Eventually, Haze genetics would arrive in the Netherlands for further hybridization, thus constituting the pinnacle of modern Sativa cannabis strains.

There, along with now-classic strains like Skunk strains, this super hybrid would capture the sweet taste and the distinctive high of a Haze. However, what makes it exceptional is that it retains the short flowering period of an Indica. By combining the genes of Haze, Skunk and Northern Lights, one of these producers ended up creating one of the first Haze classics, Super Silver Haze, a practically mythical and expensive cannabis strain, and one of the most sought-after of all time.

The smoke from Silver Haze is simply fantastic. Smokers love the instant high that accompanies each puff of a joint or bong. Super Silver Haze provides an experience of intense calm without couch-lock and allows you to go about your day-to-day tasks. Effects heads straight to your brain and puts you in a real contemplative feeling very typical of a Haze. The taste of the smoke is just as pleasant, with a very sweet flavour that thrills the taste buds and sends notes of lemon, sandalwood and incense very stimulating.

This strain is a bit difficult to grow for beginners. You will need to provide your Super Silver Haze plants with a healthy indoor environment. This variety thrives best in hydroponic environments, making it a variety best cultivated by experts or those with at least experience in growing cannabis.

4. Blue Dream

Blue Dream is a hybrid cannabis strain that develops into a potent Sativa-dominant plant. Its genetics combine Blueberry Indica and Haze to a stunning effect leading to an impressive strain famous for its vigour, its pleasant head high and its ability to treat a range of medical conditions.

Blue Dream starts its journey with a mild cerebral high which gently develops into a feeling of intense relaxation. Blue Dream offers the soothing effects of weed whilst enabling you to stay relative alert and functional. Some users experience varying effects; this depends according to the proportion of Indica or Sativa contained in the specific phenotype.

The flavours and aromas of the Blue Dream evoke its lineage of which it is a worthy heir. Think of the powerful blueberry aromas of the Blueberry, associated with the sweet and remarkable nuances of the Haze. Some users also say they perceive certain nuances of pine, even slightly herbaceous nuances.

Blue Dream is suitable for both indoor and outdoor growing. This cannabis strain generates huge yields, producing more than 600 gr per m² indoors. During its relatively short flowering period (9-10 weeks), each plant is loaded with huge buds. It is not uncommon to see them tint light blue during their development, the colour from which this plant takes its name.

5. Green Crack

Green Crack comes from the cross between 2 great classics: a Skunk # 1 from 1989 from Super Sativa Seed Club and a clone from Afghanistan. Stable genetics at a thousand possible points, thanks to which our Green Crack will hold its resistance to all types of mould, making it exceptionally easy to grow outdoors.

The structure of the plant is packed, although it is dominated by the Sativa, the Green Crack with this peculiarity coming from its Indica side. Do not get me wrong, if it is grown in the ground its development can reach up to 2.50m. If the growing conditions are optimal, it will be able to produce up to 600gr / m2 indoors or 1 to 3 kilos outdoors, that’s enough to have enough consumption for a whole year! Its flowering does not exceed 60 to 65 days, you can harvest it from mid-October to the end of October.

Its culture is suitable for beginners as well as experts and promises an easy output outdoors both indoors and outdoors. Do you dream of having a beautiful tree at the bottom of your garden? Get the supremacy of its lateral buds loaded with resins up to the top of the plant!

Terrible taste of exotic wood, which can remind incense leaves room for an aftertaste of mango and pineapple for the pleasure of the most greedy. Its complex and lasting effect stimulates the mind and creativity, pleasant to consume throughout the day you will feel yourself walking on clouds. Its euphoric side can be quickly destroyed if you harvest it more mature. Its effect will then be much more stoned, controlling anxiety and restoring a smile when anyone dares to taste it.
