Top 10 Highest Yielding Cannabis Strains for 2020

Coming to the end of a grow and harvesting monster amounts of fresh cannabis is a delight for any farmer. After months of hard work, getting your well-cured bud finally on the scales should be a rewarding experience. We've selected some easy-to-grow, high yielding cannabis strains of 2021 so you can enjoy the fruits of your labor even more.

High yields are a top priority for a lot of commercial growers these days. Cannabis will keep getting more efficient as long as breeders continue to combine genetics to create stronger strains. Potency of cannabis has reached sky high levels and yields have been improving significantly, so there is always something new waiting around the corner.

Highest Yielding Cannabis Strains

Strawberry Lemonade - Barney's Farm (700g/m2)

First up is the scrumptious Strawberry Lemonade from Barney's Farm. This Sativa dominant genetic is the product of a cross between Lemon OG and Strawberry and is bursting with earthy terpenes that shine through like real strawberries and lemons. With THC levels up at around 20%, this strain will send anyone into a refreshing paradise of relaxation with an uplifting twist.

A perfect choice for outdoor growing, Strawberry Lemonade can grow extremely tall and can produce up to a staggering 2500g per plant. As an indoor cultivar, it still manages to compete with other top yielders in this category, pushing a satisfying 700g/m2 in under 70 days flowering.

Gelato Watermelon - Purple City Genetics ( up to 650 g/m2 )

This Indica dominant hybrid that has its origin coming from a cross between Gelato 33 and Watermelon Zkittlez produces a very high yielder with very sweet aromas and citrus/earthy touches. Her potency levels are quite high with THC-levels up to 25% which gives it also great medical potential.
Indoors she can bring in up to 650 gr/m2 but outdoors she is a stunner with yields going up to 1200gr per plant and this with a flowering period of 8 - 9 weeks.

Zkittlez - Delicious Seeds ( up to 600g/m2 )

The Zkittlez strain was created by crossing the outstanding Afghan Kush Indica with a (Grape Ape x Grapefruit) hybrid. It is an Indica dominant plant with a quite powerful but balanced and relaxing, cerebral high full with a sugary sweet flavor.

Her harvest is medium to quite high with an average of around 600g / m2 indoors and 700g per plant grown outdoors and up to 22% of THC which makes it a good opportunity for in and outdoor growing!

Orange Sherbert Auto - Fast Buds (up to 650g/m2)

Another fantastic Sativa dominant auto hybrid worth mentioning is the Orange Sherbet Auto from Fast Buds. This super citrusy sherbert lady tastes amazing and has impressive yields of 500 - 650g/m2 making it great for production purposes. Not only that, THC is at 24% so the effect is just as satisfactory.

Orange Sherbert Auto grows fast and tall, bushing out as flowers develop, so a big enough space is recommended. Seed to harvest takes around 9 - 10 weeks with little maintenance, meaning it is suited to all levels of growing. For an autoflower it is a very productive plant so is definitely one not to be missed if you are looking for big yields.

Industrial Plant - Dinafem (625g/m2)

Industrial Plant from Dinafem

Dinafem has been around for 15 years and produces some of the best strains on the market. Industrial Plant (Afghan x Thai) gets its name for being mega productive in ridiculously short times. Flowering in as low as 7 weeks, this beast of a machine can provide up to 625g/m2 when grown indoors.

Outdoor plants are worth considering too as they can yield approximately 1300g per plant, which is an attractive number for any commercial grower. Industrial Plant is an overall well-balanced strain that anyone can grow with ease.

Holy Punch - Green House Seeds (700g/m2)

Holy Punch is a medium-sized plant that grows short and bushy due to its indica dominant genetics. It's packed with complex flavors that are both sweet and spicy, leaving a perfectly fruity aftertaste. Plus, it is possible to grow indoors and outdoors in a variety of climates because of its effective resistance to mold.


Its small size is not to be underestimated, as you can still grow plenty of dank weed in relatively short cycles. Indoor plants will yield up to 700g/m2, while outdoors you can happily achieve 1000g per plant. Not bad for a strain that also gives high THC of 20% and up.

Gorilla Breath - Humboldt Seeds (up to 600g/m2)

Gorilla Breath from Humboldt

Here we present to you one of the top hybrids currently floating around the US. Gorilla Breath by Humboldt Seeds is the result from cloning the well-known GG4 and OGKB to create a new wonder bud. This aromatic beauty smells like intense sweet and earthy vanilla with flavors that resemble pine and diesel. High production of resin comes with humungous growth, especially if grown outdoors.

Depending on the climate, Gorilla Breath is able to produce a whopping 3500g per plant, reaching giant heights of up to 4 metres. The indoor yield is definitely enough to keep you smiling too, at around 450 - 600g/m2. Plants do well with training techniques such as topping or LST.

Big Devil F1 - Sweet Seeds (up to 650g/m2)

Big Devil F1 is a rapid flowering hybrid cultivar with a 65% dominance in sativa. Smokers enjoy this genetic for its sweet, earthy flavors however it benefits from having both impressive THC content (20 - 25%) and big yields as well, with indoor plants growing up to 1.7 metres and producing around 500 - 650g/m2.

The effect of Big Devil F1 is energetic, leaving the consumer feeling more alert than a heavy stoned, making it a perfect choice for daytime smoking. The smell is strong due to its chunky, resin-packed buds covered in white frosty pistil hairs, which give this plant an appearance that just makes it look like a winner.

Blue Gelato 41 - Barney's Farm (up to 700g/m2)

Blue Gelate 41 is a sweet, earthy mix born from Thin Mint Girl Scout Cookies crossed with Sunset Sherbert. It is a strong, vigorous indica dominant (60%) variety with a pungent gassy odor that when smoked, reminds one of lemons and pine trees. It is best consumed at the end of the day for relaxing as the high is extremely calming, which makes it an effective pain reliever.

Blue Gelato 41 will be ready to harvest in about 9 weeks after flipping your light schedule to 12/12. High yields are to be expected at up to 700g/m2. It is perfectly suited for growing indoors due to its robust, resilient structure and is recommended for all levels of grower.

  • THC: High
  • Indoor Yield: 600-700g/m2
  • Flowering Time: 9-10 weeks

Mokam's Tulip - Dutch Passion (650/m2)

For those who like full fruity, candy-like aromas, Mokam's Tulip by Dutch Passion will not disappoint in the least. This genetic is ripping with strong terpenes that will make your nose tickle with excitement. It inherited these superb traits from its flavourful parents, Gelato and Sherbert.

On top of that, it has a quick flowering cycle of 8 weeks, meaning multiple grows a year are possible if you are cultivating indoors. With the correct setup, harvests will deliver a tasty 650/m2 of resinous buds that spill over with sparkling trichomes. To make things easier, it is also highly resilient and makes a good choice for both indoor and outdoor growing.

Conclusion

Finding the right strain to grow can be a tough choice but a lot of it comes down to your personal preferences. There are stoners out there who will prefer more potent weed, others mind more about flavor. Whatever the case may be for you, having a decent yield at the end of your grow is encouraging to help you put the right care into the process, all the way from beginning to end.

Is Grow Diaries turning into Kotaku or something?

What did this Joshua dude ever do, to give him any credibility on this subject?
- Not only that, but this is basically just a rewrite of what the breeders are saying on their own sites. Almost like he doesn't actually have any actual experience growing the strains he's promoting..

Stop giving me notifications for this bullshit.

Ive grew Strawberry Lemonade, Green Gelato and Critical Kush..in my personal opinion all 3 are above average on yeilds and all are very, very nice smokes.. Gelato is definitely the strongest out of the 3 but SL and CK are both pretty strong strains.. I think GG was my highest yeilds with SL in 2nd and CK in 3rd..Definitely recommend all 3 strains for anyone who hasn't tried them yet.. Very high class cannabis plants!!.. :+1::four_leaf_clover:

Sorry to say but this is bullshit. It is widely mown in this committee top yielding strains give upwards of 800-1000g/m2.

The second BS was the strongest strains............Anesia seeds has some of the most powerful genetics with many being over 30%THC. Their top strain which is Future#1 has up to 37% THC so I don't know why they guy is having any "strong cannabis" stories with all 20%~ strains.

Shame on you for not reviewing what's going on in the cannabis community and on this website.

Heyyyaa, I am growing some Strawberry lemonade atm. I have to say she is a beauty to grow. However, after topping, she took very long to even push another Centimeter. So I just flipped, and in consequences, have a lower yeild on a plant that refused to grow taller than 30CM in 10 weeks or less (veg). It's a hit or miss, but over all a great grow so far :)

I like this site and the community but what are these?

I don't like these advertisement "journals" that has nothing to do with reality. :rage:
If you @JoshuaHolt want to advertise strains then please make ads and not fake journals.
If you on the other hand want to make journals then please provide some PROOF of these numbers and maybe links to succesfull diaries? Also the "HIGHEST THC STRAINS" Journal was BS. No scientific reports or any proof to back those numbers or anything else. Just empty words fueled with money.

Sorry but I really don't like these and I hope no one takes these seriously, peace :v:

Edit: There is external reference link so maybe there is proof after all. Sorry I have to check it out
