Top 10 High THC Strains​ : what are the strongest cannabis strains?

Looking to grow something that will get you really high? But like I mean, really really high? Then you’ve found the right list! Here I will present some of the strongest strains I’ve come across through my research.

This list contains marijuana strains with 25% THC or over that I can personally recommend or that I’ve found enough user reviews to feel confident in recommending.

Before we start it’s important to point out that some strains have greatly evolved over the years and despite having the same name, depending on which vendor you buy it from, characteristics may vary.

Advantages of high THC strains​

Some people might wonder what are the advantages of high THC strains. First of all, they can help with many illnesses as they’re great for appetite stimulation and pain relief. Find out more about this in our medical marijuana section.

Some people also look for strong marijuana strains in order to consume less weed and still get the same effect. Whether it be for monetary or medical reasons, some people just can’t consume too much and therefore a stronger strain can help with that.

What determines THC content?​

Many factors come into play when it comes to a plant’s THC content. First of all obviously genetics, different strains have different lineages with each their own THC content. But that’s not all, how you grow the plant is going to alter it’s THC content.

All along the grow cycle you influence the quality of your final product. During flowering time, and especially the second half of that time, is when you start to influence the final THC level of your plant. Some determining factors are: how much light the plant gets, how humid the environment is, what time you choose to harvest, and even how you dry your buds.
