Top 10 most powerful cannabis strains

Even though CBD-rich strains are becoming increasingly popular, many consumers still want to grow the most potent cannabis strains. Genetics offering very high THC concentrations, for notable psychoactive effects.

In this article we will focus on the most potent cannabis strains available on the market. Some can concentrate THC levels above 30%, genetics reserved for the most experienced users. Before we list the 10 most potent cannabis strains in the world, let's first look at what defines potency in cannabis.

What is cannabis potency?

When consuming cannabis, even the most inexperienced consumers may notice significant differences between the varieties of cannabis available. Depending on the type of genetics, more or less Indica or Sativa, it will be possible to feel more or less stimulating, energizing or on the contrary relaxing effects, either at the muscular or cerebral level.

The concentration of the different cannabinoids developed by the plant will influence the strength of the effects experienced. For example, a strain with 12% THC will have a more muted effect compared to the world's most potent cannabis strains that can produce over 30% THC.

It should be noted, however, that it is not only THC that is responsible for the potency of a cannabis strain. It's a whole! We now know that the range of terpenes produced by the plant also influences the type of effect and the overall potency of the harvest obtained.

Is it possible to increase cannabis potency?

The potency of a cannabis strain is determined by the genetics itself, but is it possible to make a cannabis strain more potent?

Growing conditions will obviously play a very important role in the production of cannabinoids, including THC. Proper nutrition will produce more trichomes in the most potent cannabis varieties.

Optimising your cultivation is key if you want to grow the most potent cannabis strains in the world. Care should be taken to ensure that the growing environment is ideal for the plants to thrive and that a stable temperature and humidity level is maintained throughout the growing process.

Basic nutrition can be supplemented with flowering stimulators, such as microbial life or sugars and carbohydrates. Some products can be added during cultivation to increase trichome production using the famous Delta 9 from Cannabiogen or Sugar Royal from Plagron.

Another very important point to enjoy the most potent cannabis strains is to harvest the plants at the right time. If you don't know how to harvest potent cannabis, you'll need to carefully monitor the maturation of the trichomes. Using a magnifying glass, the resin on the heads should be observed.

Once the trichomes are mostly milky, and before oxidation begins, the plants should be harvested. If you harvest too early, or too late, the concentration of cannabinoids may vary and thus the potency of the harvested herb. Take your time and harvest the most potent cannabis varieties at the right time.

The conservation of the harvest should not be neglected in order to be able to enjoy the most potent cannabis varieties possible. Store your herb in an airtight container, away from light, in a cool place, and with a humidity between 50 and 60 %. Keeping it in good conditions will allow you to enjoy the power of your herb for a long time.

Is there a way to measure the potency of cannabis?

Although it is possible to notice the potency of cannabis at the time of consumption, it can be interesting to know the precise cannabinoid content of a newly harvested herb. This will allow the consumer to know the exact THC concentration, but it is also interesting for people who only want to consume CBD and want to be sure that their harvest is THC-free.

However, this operation is not necessarily very simple to carry out. To find out the exact percentage of cannabinoids, the most reliable solution is to send a sample (herb, hashish, rosin, etc.) to a laboratory that performs this type of test.

The most famous is the laboratory of the Foundation Canna, which analyses cannabinoids, but also terpenes, heavy metals, pesticide residues and moulds. The best way to be sure of the quality and potency of your cannabis!

However, for several years now, there have been solutions available to all growers, with tests that can be carried out at home, which do not require much equipment or special knowledge.

Companies such as Alpha-Cat offer kits to perform this type of test, called thin layer chromatography (TLC). This type of test does not give you the exact percentage of cannabinoids, but it does give you a fairly accurate idea of the THC or CBD concentration of the sample being tested.
