The main external factors influencing the strength of your bud are: Location (e.g. indoor vs outdoor), growing medium (e.g. soil or hydroponics), nutrient levels, light source, temperature & humidity and carbon dioxide levels.

Although there are many methods of growing cannabis, they all come with a different set of pros and cons . for example, if you wanted to grow your plant under some of the UVB spectrum, you would either have to find a nice mountain close to the equator or purchase some UVB emitting LEDs. Both of these methods have problems; LED lights are rather expensive, and walking up a mountain to grow your bud will also leave you feeling pretty low on energy.


While we’ve had access to plenty of strong cannabis strains for quite some time, there are new advances in the field every day. We’re happy to present an updated list of some of the most potent varieties of the bunch. Featuring new strains like Cookies Gelato and Triple G, as well as some of the old-timers!

So now we’ve got that out the way, what are the best and strongest strains out there?

Stable genetics produce predictable features passed down from parent strains, whereas unstable genetics can often give the offspring unpredictable features which can be difficult to manage.

Powerful hybrid cannabis strains:

Original Glue is named for the stickiness of its resinous buds, and this strain certainly lives up to its name. Multiple Cannabis Cup awards serve to back up the legends of Original Glue’s potency, but we doubt you’ll need the proof once you’re stuck to the couch in stupefied contentment.

Born from The White and Fire OG, White Fire OG (also known as WiFi OG) is a force not to be trifled with. Uplifting euphoria launches your mood into the clouds with an elevated feeling that will shake creativity and happiness wide awake.

Bred by Rare Dankness Seeds, Ghost Train Haze has proven to be a lively and vigorous strain. Inheriting genetics from Ghost OG and Nevil’s Wreck, Ghost Train’s potency takes form in a jolt of euphoric energy that goes straight to the head, feeding focus and creativity.

GSC and the many Cookie-crosses descending from it have hauled their way up the ladder of fame over the last several years, and it isn’t hard to see why. Expect a crushing wave of blissful euhoria that enshrouds both mind and body with warm relaxation for hours.

Named for the whiteout of crystal resin cloaking her buds, The White has become a godsend for breeders looking to improve the potency of their genetics. The White delivers a disorienting blizzard of euphoric delirium that commands relaxation.

Godfather OG can yield up to 450 grams per m2 when grown indoors under ideal conditions. Outdoors, plants can yield up to 650 grams per m2. However, her flowering time is only 49 to 63 days. She is a great favorite among growers partly because of this.

Chiquita Banana likes to be grown both indoors and outdoors. Indoors, the plant is capable of yielding up to 400 grams per m2. When grown outdoors, her yield can reach up to 600 grams per m2.


As the name suggests, Sirius Black’s leaves and buds are dark in color with magical purple hues. Just like Sirius Black from Harry Potter. She has medium mold resistance and is preferably grown in a warm, dry climate. It is also a plant that you can easily put in a SoG (Sea of Green) setup (as long as you have good ventilation).

When growing indoors it is advisable to keep the humidity low to protect the buds from mold. Outdoors it should be grown in light, well-drained soil.

These overwhelmingly strong sedative properties make her an ideal tranquilizer for insomniacs. Sirius Black is also commonly used by medicinal users for inflammation, pain and seizures.
