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?

HULKBERRY

Colorado was among the first states in the US to legalize recreational marijuana. The first-movers of that state have been cultivating some of the most impressive hybrids known to humanity. A particular standout is already taking dispensaries by storm, and has made its way to Europe and beyond. HulkBerry has attained cult status in a short amount of time following its success at the 2014 High Times Cannabis Cup. It was unmistakable how strong this strain was, with a THC content surpassing 28%. The breeding of OG Kush with Strawberry Diesel means a powerful mix of indica and sativa effects will accompany a delicious fruity taste.

TRIPLE G

Yes, it's a coincidence that the name of this strain is similar to that of the WWE wrestler, Triple H. However, that doesn't mean there are no similarities. For one, they could both knock you down if you aren't careful. Although Triple G is not the most potent on the list (with 26–28% THC), the fact that it's indica-dominant means it'll do more than get you relaxed and euphoric—it can easily make you fly away. If you are a medicinal user and you're experiencing insomnia, chronic pain, or appetite loss, Triple G might go a long way in easing your symptoms. Expect the taste of berries, candy, and chocolate to hit your tongue, while spice, diesel and earth scents waft around you.
