The Top 5 Strongest Cannabis Strains — 2020 Update
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!
Determining the strength of cannabis is not always straight forward, once you have have chosen which strain you would like to use, there are also a number of factors which will affect the THC content of the bud.
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.
Genetics also affect the strength of the plant. Genetics are what holds all the information about the plant. How much THC and CBD it produces, how it smells and tastes and how it grows. Cannabis displays a mix of traits from their parent strains just like humans.
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.
Nowadays, cultivators are able to select desired characteristics of growth, appearance and effect. This can be really useful in finding a strain that’s right for you and your needs.
That being said, it’s important to take all these factors into consideration when you begin your garden so that you know what kind of strain is most suitable for you. Landrace and heirloom seeds for example, have been cultivated for centuries and have traits specific to adapting to their native environment. On the other hand, when growing indoors you may want to find a strain that is less pungent, smaller in size and more pest resilient. It is for this reason that you should have a good idea about how you intend to grow your garden before you chose your seeds.
So now we’ve got that out the way, what are the best and strongest strains out there?
Combining the sugary sensations of Girl Scout Cookies and Gelato, the aptly named Cookies Gelato is a recent entry on this list and has more than earned its spot. You see, besides inheriting a sweet flavour and aroma from its parent strains, it’s got a lot of THC; around 28%, to be exact. Bringing about a euphoric rush with a relaxing touch, this hybrid makes sure you don’t go too deep in one direction, even if you’re headed for the stars. Needless to say, this might not be for you if you’re a novice smoker, but those with a bit of a tolerance will have an unforgettable time with this luxury treat.
Cannabis has only become stronger with time, and these five strains are the cream of the crop when it comes to packing a THC-fuelled punch.

What seeds to buy? Cannabis seed banks typically categorize the seeds by sex, genetics, breeder, strain name and plant traits.
Cannabis Seeds by Sex
- Regular Seeds: Grow both male and female cannabis plants. The males are culled in sensimilla (seedless bud) production. Regular seeds are the best choice for breeders. They have sustained the cannabis genus through its natural evolution.
Read—Top 15 Best Regular Seeds
- Feminized Seeds: Grow only female plants. This is accomplished by breeding two female cannabis plants together. The resulting seeds can only inherit two X chromosomes—meaning all female plants. Feminized seeds are great for growers with strict plant limits and for cloning. Read—Top 15 Best Feminized Seeds
Cannabis Seeds by Genetics
- Sativa Seeds: Grow into tall plants with slender, elongated branches, sharp leaves and large colas. Sativa originates from subtropical/tropical zones including Africa, Southeast Asia, South & Central America. The plants have a naturally long flowering cycle that’s often over 10 weeks. Resistant to molds and diseases, sativas are great outdoor climate strains. They can grow to over 15 feet tall! High THC and THCV content. People who enjoy a stimulating “head high” effect prefer sativa cannabis. Read—Top 25 Best Sativa Seeds
- Indica Seeds: Grow short plants with fat leaves, thick stems and a stocky structure. Indica originates from temperate zones such as Afghanistan, Pakistan, India, Nepal and Morocco. Traditionally used to make hash, indica cannabis is the real deal dank—super sticky and dense. Indica grows like a bush and can produce large yields in a small area. The plants have a fast flowering cycle. They may require a low humidity climate to avoid mold problems. High THC and CBD content. People who want a relaxing “body high” stone prefer indica cannabis. Read—Top 25 Best Indica Seeds
- Hybrid Seeds: Grow crossbreeds of indica and sativa, in countless combinations. Hybrid cannabis seeds are able to grow tall sativa trees that produce the dank, heavy buds of an indica. Hybrid cannabis strains are by far the most popular category of cannabis seeds sold on the market today. They come in all different plant sizes, flowering times, yields, aroma, flavors, cannabinoid contents and effects. Read—High Yield Seeds List
- *Autoflowering Seeds: Grow plants that flower automatically (non-photoperiod). The seeds may be either feminized or regular. Autoflowering varieties are made with ruderalis genetics, resulting in seeds that will bloom under any amount of light—including 24 hours/day. Auto strains stay short and finish their life cycle fast, some at under 60 days from seed. They benefit from long light hours per day to produce a decent harvest weight. The plants can be spaced closely, as in SOG or SCROG cultivation methods. Autoflowering cannabis seeds are used often by indoor cash croppers, who cycle them indoors for perpetual harvests.

☺ Cannabis seeds are also categorized by their unique traits such as high THC strains, high CBD strains, high yield strains, landrace genetic strains, inbred line strains, award winning strains and more.
