Top High Yielding Strains for 2021
The long-awaited ranking of the top high yielding strains for 2021 is here. This 2021 is a year full of incredible novelties, but also one with absences, those of Dinafem and Humboldt Seeds, two of the producers that always obtained good places in this list of the most productive marijuana seeds of 2021. In this article you will find out about this year’s highest-yielding cannabis seeds.
In order to compile this ranking of the most productive marijuana seeds of 2021, we have selected novelties whenever possible, which is why almost all of these strains are new. This 2021 year, the manufacturer with the highest number of places in this ranking is Barney’s Farm, a manufacturer that, in fact, is always on the top of our annual rankings.
What is productivity and how is it measured?
The productivity of a cannabis seed is its capacity to produce a certain amount of fruit at its full maturity. In other words, once it is harvested, it is the one that produces the most amount of flowers.
Normally all seed manufacturers in the world do their own laboratory tests, there is where they make measurements and draw conclusions. The industry standard is to make measurements indoors and outdoors. For the production capacity indoors, grams per square meter is the standard measure, while for the yield capacity outdoors, the common measure is grams per plant.
Last but not least, we have to take into account the fact that not all banks measure in the same way, but don’t worry, in our work we also know this fact, so we weight it for you. To give you an example, the indoor production measurements of the Greenhouse seed bank is always going to be higher than the one provided by other seed banks, this is because they carry out their tests with greater lighting power.
The most productive marijuana of 2021
The selection criteria for these varieties with the highest production of 2021 is as follows. First we prioritize the values offered by the manufacturers, then we take into account the results of the most reputed cannabis cups, then we confirm this data with breeders and growers, to finally offer you the best and most reliable list with the most productive marijuana of 2021. Without further ado, these are the ones:
Lemon Tree
As we said, Barney’s Farm always pleases all its fans with outstanding strains. This is the case of the new 2021 Lemon Tree, an excellent American genetics, capable of producing XXL yields.
These new seeds come from crossing Lemon Skunk with Sour Diesel, giving rise to a new hybrid genetics with very high yields. Specifically, the manufacturer indicates that in a flowering period of only 65-70 days, Lemon Tree marijuana can produce up to 650 grams per square meter indoors. Outdoors, when given the best conditions, it can reach up to 1500 grams per plant.
But this ultra-productive strain is not just that. Lemon Tree also stands out for its aromatic profile marked by limonene and myrcene terpenes, which give it a citrus and spicy fragrance at the same time. 
GH Amnesia
We continue with the most productive marijuana seeds of 2021 with the GH Amnesia from Greenhouse Seeds, a version of the well-known Amnesia strain taken to its most productive profile. This 65% sativa-indica strain promises a yield of up to 900 grams per square metre, although as we mentioned above, coming from the Greenhouse bank, it is an exaggerated figure compared to the one given by other manufacturers. But, from independent consultations, we can comment that this is one of the most productive strains of 2021.
GH Amnesia offers medium to tall plants, but with short internodal distance, which ensures an optimal ratio of flowers to leaves. It grows vigorously and, when it reaches the final weeks of flowering, it offers a striking orangey colour.
The aromas that are characteristic of this strain are complex, an original blend of nutty, petrol and olive notes, all wrapped up in a creamy sensation. 
Godzilla Glue
Third on the list of the highest yielding cannabis strains of 2021 is Godzilla Glue, an Indica hybrid from the Dr. Underground seedbank. This strain is the result of crossing two of the highest yielding marijuana strains ever seen, King Kong and Gorilla Glue #4. Specifically, this strain comes from the famous King Kong elite clone known as “Brutal Kong”.
Dr. Underground claims 1.5kg per square metre of production indoors, although this is also a figure to be taken with caution. This is a number the bank says, when the crop is provided with the optimal conditions and “advanced training techniques” are used. This means having an aeroponic system at maximum capacity and with at least 1200 watts of HPS or 850 watts of LEC light per square metre, when it is normal to have at most half that. A weighted value of this yield would be 700 grams per square metre, which is also one of the best marks of 2021.
In addition to this, Godzilla Glue has a short flowering period and a cocktail of many different terpenes, such as pinene, myrcene, ocimene and guaiol, which give it a deep and complex aroma. 
Grape Amnesia
We continue with a nice welcome to Female Seeds, a manufacturer of great value for money, which debuts today in our rankings of the best with its Grape Amnesia. Also being a fantastic strain, its price is quite affordable.
Grape Amnesia is one of the most productive marijuana plants of 2021, from Female Seeds they point to an indoor yield that can reach up to 700 grams per square meter. When grown outdoors, it can reach up to 2kg per plant, figures that are more than adequate and are considered top high yields.
To create this new high-yielding strain, an elite clone of Amnesia has been used, which has been crossed with their well-known Cindirella 99, also known as C99. The result is a Sativa-dominant hybrid strain with fruity terpenes and a high presence of active cannabinoids. 
Purple Punch
Speaking of great deals, we come to one of the best affordable producers, the 00 Seeds bank, a manufacturer that every year surpasses itself and makes varieties of great relevance and prestige available to collectors, always at the best price. In this case they present its Purple Punch, one of the most productive feminized strains of the year 2021, as well as one of the cheapest.
00 Purple Punch strain is the result of crossing Granddaddy Purple and Larry OG, to give a new variety with Indica dominance, small and compact, but with a production capacity beyond any doubt. The 00 Seeds bank says that its Purple Punch can reach up to 700 grams per square meter, always in optimal indoor growing conditions.
00 Seeds indicates 22% THC production capacity, this together with the indica dominance of this variety makes its effects are intense and mainly relaxing. 
Mimosa x Orange Punch
Probably the best strain of 2021 in all aspects, already featured in our list of the most potent marijuana of 2021 and now in this list of the most productive marijuana of 2021. This is a cross of two of the most successful genetics of recent times. Offered, once again, by the prestigious bank Barney’s Farm, which is always at the forefront of the market.
Mimosa x Orange Punch marijuana seeds performs huge yields, its large buds, violet and orange, are a catch to the eye and in weight. The bank indicates in its data sheet values of up to 700gr/m2 for indoor growing, while outdoors it could produce up to 1.5kg per plant.
In addition, it has the capacity to produce up to 30% THC, one of the highest values ever seen on the market. It is therefore a strain that produces a lot of everything.
Other notable features of this variety are its fast flowering time, as it is ready in a flowering period of only 55 to 60 days, as well as its aromatic properties, which offer a distinctly citrus fragrance. 
Moby Dick
Finally, we would like to highlight one of the most productive strains of 2021, Moby Dick from Seedstockers, a version of the well-known Dinafem strain, which is now back on the market at an unbeatable price.
Seedstockers’ Moby Dick is basically the Dinafem strain, but packaged by another bank, at a much lower price. This is a great opportunity to add this multi-award winning strain to your collection, now at a fraction of its price from a few years ago. Although this is a strain that has been around for many years, we wanted to highlight it in the 2021 list, as this is the year it has been re-released by Seedstockers.
Its credentials are widely known, great production capacity, lots of cannabinoids and a very sticky citrus aroma. Specifically its production capacity reaches up to 650gr/m2 indoors and up to 1,5kg per plant outdoors.
