Best High-Yield Weed Strains for 2020

Nine of the Best High-Yield Cannabis Strains and How to Grow Even Larger Crops

Cannabis strains are frequently bred to produce particular types of highs or even striking-looking buds. It takes a lot of time and effort to bring a crop to harvest, though, so growers often seek out strains that are known for high yields if they are going to invest time and resources into growing this fascinating plant.

Fortunately for them, cannabis breeders have devoted more effort to boosting yields than pursuing any other goal aside from ramping up THC content. There are now dozens of cannabis strains on the market that combine high yields with other desirable features. A look at nine of the most popular and impressive follows, ordered by expected yield when grown indoors.

  1. Triple XL

Expected yield indoors: 800-1000 g/m2

Most heavy yielding strains today are meant to be at least somewhat well-rounded. Triple XL is a bit of a throwback in that it emphasizes yield to a degree not seen with many modern strains.

The famously large buds that add the “XL” to its name allow this strain to put up yield numbers that few others can approach. As a cross between two indica-heavy hybrids, a well-known sativa, and Cannabis ruderalis, Triple XL features a fairly stony high and a moderate level of THC. It might seem a bit gimmicky compared to some high-yield alternatives, but Triple XL delivers on its promise of generating huge buds and impressively large crops.

  1. Big Bud

Expected yield indoors: 600-800 g/m2

Big Bud’s name says it all, much like Triple XL, one of its best-known descendants. Although big bud does not quite reach Triple XL’s yield numbers or bud size, it brings a bit more to the table in certain respects.

Some fans find Big Bud’s aroma superior to Triple XL’s similarly earthy nose, for instance. Like Triple XL, Big Bud is by no means the fastest flowering cannabis strain, but does develop fairly modest amounts of THC.

Although it is 85 percent indica, Big Bud produces a high that starts out lively and then settles down to a more characteristically mellow experience. A tendency to produce few leaves boosts effective yields and makes for slightly easier processing.

  1. Critical Mass

Expected yield indoors: 500-750 g/m2

Whereas both Triple XL and Big Bud are known for their notably large buds, Critical Mass mostly shines with regard to density. It has a reputation for producing buds so sizable and heavy that they fall off before being harvested.

With a fairly high level of THC and two-to-one indica-to-sativa genetics, Critical Mass is a favorite of medical marijuana users looking for help with pain management or sleeping. Critical Mass comes from a refinement of the approach that created Big Bud, courtesy of a well-known Dutch seed bank. It matures at a reasonable rate and is often recommended to novices.

  1. Moby Dick

Expected yield indoors: 500-750 g/m2

Sativa-dominant hybrid Moby Dick has been credited with some of the most impressive yields of all. While reliable-seeming reports of up to 1500 grams per square meter indoors have been seen online, most growers are happy with half that figure.

Moby Dick’s legendary yields are far from its only desirable feature. Its healthy THC levels combine with its sativa heritage to enable highs that many fans find especially enjoyable. As a daytime smoke for most, Moby Dick is often used to combat anxiety and depression, and is also a favorite of many recreational users.

The main reason for the variation among reported Moby Dick yields is simply that it is a fairly demanding strain in terms of required pH and electrical conductivity. Once growing conditions have been established and stabilized, though, most find that it needs little attention.

  1. Super Silver Haze

Expected yield indoors: 500-600 g/m2

Another high-yield, sativa-heavy hybrid, the super silver haze strain has won many awards over the course of its long history. Its pungent aroma comes courtesy of an even older parent, the legendary and prolific Skunk #1.

Super Silver Haze is a wake-and-bake standby for millions, since its sativa high perks users up like few others. A moderately high average level of THC helps keep Super Silver Haze from ever feeling overwhelming.

As with Moby Dick, Super Silver Haze yields vary more in practice than the conservative estimates above suggest. Super Silver Haze is somewhat finicky itself, but there are also a couple of closely related versions of the strain on the market that account for some of the variation.

  1. Amnesia Haze

Expected yield indoors: 500-600 g/m2

Amnesia Haze combines one of the most influential sativa hybrids with a number of indica and sativa cannabis landraces from all over the world. It retains its hybrid parent’s 80-percent sativa heritage and is known for a focused, creative high belied by its name.

Despite being heavy on sativa genes, Amnesia Haze develops in a fairly bushy fashion that makes it easy to grow indoors. It does take time to mature, with indoor flowering times of up to 12 weeks making it the slowest on this list.

That puts most commercial growers off, but Amnesia Haze’s other features have made it a favorite of many amateurs. Generous yields combine with an appealing high and unusual genetics to make Amnesia Haze interesting and a little different.

  1. Gorilla Glue #4

Expected yield indoors: 500-600 g/m2

The #4 variety of Gorilla Glue is probably the most popular of the numerous strains with this well-known name. Unlike the other members of the family, Gorilla Glue #4 came into being by accident, when, legend has it, a hermaphrodite mistakenly got pollinated.

As its name suggests, Gorilla Glue #4 is known for producing plenty of sticky resin, but it also features notably high yields. Although it leans toward sativa, Gorilla Glue #4 encourages a fairly relaxing, mellow high. Its very low CBD levels might limit its efficacy at treating many physical disorders, but people suffering from anxiety and the like often find it appealing. Get your gg #4 seeds here at

  1. Bruce Banner

Expected yield indoors: 450-600 g/m2

Combining high yields with exceptional THC levels, bruce banner is a favorite of growers who aim high. Some Bruce Banner buds have been reported to reach the level of 30% thc strains, and the #3 variety of the strain still holds the official Cannabis Cup record.

That and everyday results experienced by growers have helped Bruce Banner #3 become the default at most seed banks, with other members of the family now being scarce. Growers appreciate Bruce Banner’s reasonable flowering time, as well as the way it combines high THC levels with yields that outpace most other OG Kush descendants.

  1. Power Plant

Expected yield indoors: 450-550 g/m2

Starting with a hardy sativa landrace from South Africa, Power Plant’s breeders aimed to produce one of the most fast-flowering, disease, and mold resistant marijuana strains available. This strain features very healthy yields and an uplifting high. They were successful enough that Power Plant has gone on to win quite a few awards, an accomplishment for a hybrid with roots well off the beaten path.

A moderate level of THC makes Power Plant accessible, and many medical users find that it helps alleviate depression and nausea while boosting appetite. Although it can be planted outdoors, most opt to grow Power Plant inside, which is the type of cultivation its breeders focused on.

There are Plenty of Other Ways to Improve Yields

The nine strains of cannabis seeds above cover a lot of ground in terms of what they have to offer, but all produce yields ranging from healthy to exceptional. Of course, there are many other yield-focused strains worth considering, which is one of the things that makes growing cannabis so interesting and rewarding.

Regardless of the strain you opt for, other decisions you make and actions you take will significantly impact yields, too. Some of the issues that can cause yields to balloon or plummet are:

  • A single cannabis plant grown outdoors will often produce a lot more marijuana than one of the same strain cultivated inside. That plant will also take a lot longer to mature, even to the point of allowing multiple indoor crops to beat it to harvest time. Switch to a hydroponic system and yields can rise even higher, since plants expend less energy seeking out nutrients.
  • Make sure that your cannabis plants grow in a medium that supports the intake of nutrients and water, and yields will improve. If pH or electrical conductivity levels in a growing medium stray too far from the ideal, yields will suffer.
  • Cannabis plants require large quantities of a number of macronutrients and smaller amounts of about a dozen other elements. Even a slight nutritional deficiency can lessen yields, particularly if it intrudes into flowering time.
  • A lack of light or uneven coverage can stunt the flowering of otherwise healthy cannabis plants. Lighting schedules need to be adjusted late in a plant’s life to maximize yields.
  • Training via topping or nondestructive methods will encourage cannabis plants to produce more, larger buds. Even novice growers can quickly master low-stress training techniques that improve yields without endangering plants.
  • Judging when to harvest cannabis plants is not always straightforward. Harvesting too early can cut yields significantly, even when no other mistakes were made along the way.

Between choosing an appropriate strain and paying attention to matters like these, it should always be possible to generate healthy yields with a cannabis crop. Even growers who prioritize other issues appreciate abundant harvests.
