For those still getting to know more about marijuana seeds, for sure you’ve already heard of the three letters T, H, and C. Most often, THC is always mentioned when describing a cannabis strain or comparing strains with each other. So what is THC?
THC stands for “tetrahydrocannabinol” and is the chemical behind marijuana’s psychological effects after smoking. It is the natural compound responsible for the sensation often described as “high” by cannabis smokers. Users familiar with the euphoric, uplifting, and even sedating feelings when smoking marijuana should thank THC for that.
Basically, THC is the one responsible for a specific strain’s potency. The higher the THC level, the more potent a strain can be. But a higher potency does not necessarily mean a better experience for everyone. This is when a user’s THC tolerance comes into play. First-time users may get overwhelmed when taking a strain with a THC level of around 20%. But for seasoned users, a higher THC means a more exciting experience.
As such, a great priority is given by cultivators to seeds that have high THC content due to the high demand. Some high THC strains are even hard to come by at the store while some are kept guarded in preparation for cannabis competitions.
So for those who would seek out to explore the limits of the mind and what cannabis has to offer, we’ve made a list of the best seeds with high THCs in the market. We did not simply decide based on which one has the highest levels but also considered the overall experience–that includes the flavor, effects, growth difficulty, and character.
