In recent years the potency of cannabis has increased along with typical THC levels. The cannabinoids present in modern buds are much higher than those from a decade ago.
The benchmark for a powerful cultivar seems to rise frequently.
So what makes one strain better than the next? Are high THC indica strains all potent? Join us as we discover the answers to these questions. We also provide you with a list of powerful indica options to try.
Let’s get started by looking at how to select a heavy indica strain.
What makes one indica strain better than others?
Before deciding on the strongest indica strain, we need to establish a criteria. Does higher THC content automatically mean a better bud? Not necessarily.
While high THC content may be a common criterion, the quality of cultivars extend beyond these levels. There are hundreds of these cannabinoids, and their unique interactions affect the traits of the strain.
Scientifically, you can divide cultivars into chemotypes. The term classifies strong indica strains according to their chemical makeup. The specific ‘blend’ of these compounds results in a unique experience. The current classifications are:
We can classify strains according to their dominant compounds. These influence the effects and your energy levels after toking.
The dominant terpenes influence the scent, flavor, and even the effects of a strain. In 2018, researchers discovered three distinctions based on terpenes.
Let’s take a closer look at these in the table below.
|Compound chemotypes||Terpene chemotypes|
|THC chemotypes: THC dominant chemotypes produce euphoric psychoactive sensations. The potency affects your perception of time, and your thoughts get hazy. High-THC indica strains form part of the first category.||Myrcene dominant chemotypes: These varieties contain myrcene and pinene terpenes. Kush plants usually belong to this category. The aromas are mostly pine with hints of earth.|
|CBD chemotypes: The experience is mellow and relaxed with CBD dominant chemotypes. Medicinal users favor these options for their reported health benefits. These strains don’t typically induce psychoactive effects.||Limonene and beta-caryophyllene chemotype: Limonene is responsible for fruity citrus scents and is present in orange rinds too. Beta-caryophyllene is commonly found in pepper and gives high THC indica strains a spicy flavor profile.|
|Mixed chemotypes: When a strain contains high quantities of both THC and CBD, the effects are different for indica vs. sativa strains. These usually induce balanced sensations of positive energy and uplifted moods. |
Unlike heavy indica varieties, mixed chemotypes tend to be relaxing without inducing sedation.
|Terpinolene chemotype: Cultivars with terpinolene as the dominant terpene offer a floral, woody profile with allspice notes. It’s typically found in sativa variants but can have sedative effects when combined with other compounds.|
