Looking for bigger yields? You’re not alone. Most cannabis growers are constantly searching for ways to improve the size of their harvest without affecting the quality of their bud. Hence, we’ve put together this list of our biggest-yielding strains that’ll leave you with awe-inspiring harvests of top-tier bud.


Sweet ZZ literally smells like something out of a candy shop. If you love saccharine aromas and complex flavours, this strain is a must-try. Sweet ZZ is a unique blend between Grape Ape and Grapefruit, two very aromatic strains known for their potency and big yields. This is an indica-dominant cultivar, which becomes very clear in the grow room; these plants grow to roughly 80–140cm and flower in about 7–9 weeks.

Sweet ZZ starts developing its unique, fragrant aroma during the vegetative phase, which only intensifies during bloom. At the same time, this plant will get to work maturing a thick central cola and smaller buds on its branches. Toward the end of the cycle, you’ll notice plants getting heavy with big, resinous, and aromatic buds.

Come harvest, make sure you’ve got some time on your hands. This strain is first on our list for a reason; it produces really impressive harvests of up to 500–700g/m² indoors and 400–600g/plant outdoors.

Shining Silver Haze is our star Haze strain. Combining some of the best genetics, our breeders have managed to create a Haze that delivers big yields and extra potency, all within a short flowering time. Our Shining Silver Haze is roughly 75% sativa-dominant and was bred to create a new, fresh tribute to the classic Dutch Coffeeshop favourite, Super Silver Haze.

And while it performs well indoors and out, we recommend planting Shining Silver Haze outdoors to accommodate its big structure. These plants easily grow over 2m tall and can prove tricky to manipulate indoors, especially for beginner growers. Wherever you decide to sow your seeds, make sure your plants get plenty of light to reach their full potential.

Once ready to harvest, this strain will reward you with big, eye-catching buds. Yields can obviously vary depending on a number of factors, but under the right conditions, Shining Silver Haze can produce 600–650g/plant outdoors and up to 650g/m² indoors.

Somango XL is one of our star indicas. This strain produces thick, eye-catching buds with a fruit-forward aroma. And it’s not named “XL” for nothing; while it might grow small, the plant can produce some incredible yields.

A cross between Somango and Critical 47, this strain has very obvious indica genetics. Think small plants of roughly 60–120cm with short internodes and branches. By the time bloom comes around, these plants start to produce a delicious fruity aroma. That aroma deepens as the plant bulks up with thick, characteristically indica-style buds.

Somango XL needs roughly 8–9 weeks to reach full maturity. It is particularly well-suited for training techniques as it is small and easy to manipulate. Remember, this is one of our special “XL” strains. When harvesting indoors, you can expect to bring in about 575g/m². Outdoors, yields can vary, but tend to be around 600g/plant.

Haze Berry is exactly what you'd imagine—a cross between a powerhouse Shining Silver Haze and Blueberry. And the results are spectacular.

This strain combines the best of Dutch and US genetics, making for a sturdy plant that produces huge yields of extra-tasty bud. Although it is 80% sativa-dominant, Haze Berry is a very balanced strain. It delivers the high of an indica, yet grows more like a sativa, developing into a tall plant with thin, light green leaves.

Despite its sativa-dominant genetics, Haze Berry can still grow well indoors. If controlled properly, these plants only reach about 60–100cm and produce yields of 525–575g/m². Outdoors, Haze Berry likes plenty of light and big pots. In these conditions, it can easily produce over 600g/plant.

As you probably know, the yields of your cannabis plants can vary based on a variety of factors outside of their genetics. Soil, lighting, nutrients, space, and other environmental factors can all affect the growth of your plants and, ultimately, their ability to produce a sizeable yield.

To maximise your yields, we generally recommend growing indoors because it gives you far more control over a number of these variables. However, keep in mind that many strains thrive outdoors, especially when grown in big-enough pots. There is, after all, no lighting substitute for the sun’s rays.

Training is also really important to keep in mind. Many strains respond exceptionally well to high-stress and low-stress techniques, so be sure to experiment with things like topping, ScrOG, fimming, and more to really push your plants to the limit.
