Why Grow High-THC Seeds?

High-THC weed strains from the Azarius seed bank are some of the most potent genetics you can get your hands on. You'll want to buy strains with a high THC content if you're after a long-lasting and powerful experience. Growers and smokers value these genetics for several reasons, such as having developed a high tolerance to THC or simply because they prefer hard-hitting and longer-lasting psychoactive effects.

What Is THC and How Does It Work?

THC underpins the potency of cannabis. This molecule occurs in the trichomes of weed flowers in varying concentrations depending on genetic and environmental factors. When smoked, vaped, or eaten, THC enters the brain, where it triggers the release of the feel-good molecule dopamine, resulting in a euphoric effect. Investing in high-THC weed seeds means you'll get more of this cannabinoid with every inhalation.

What Is Considered High THC?

Cannabis users often ask questions such as "What percentage of THC is enough?" and "Is 20% THC a lot?". In truth, THC affects people differently based on factors such as tolerance and genetics. However, quantities of 25–30% are generally recognised as a high THC level.

How to Choose a High-THC Cannabis Strain

When buying high-THC marijuana seeds from our seed bank, you'll want to take some time to look at each strain's unique traits. Aside from the THC level (which will determine potency), check out the terpenes in each variety to get an idea of the flavours and effects they provide. You'll also want to consider the size of each plant and how much of a harvest you can expect to receive.

Are High-THC Feminized Photoperiod Seeds Stronger Than Autoflower Seeds?

Traditionally, most growers opted for feminized photoperiod strains when looking to buy cannabis seeds with high levels of THC. However, breeders have worked hard over the years to raise concentrations in auto strains. F1 hybrid autos, for example, offer huge levels of the cannabinoid. When looking to buy plants with the highest THC concentrations, you should definitely consider autoflowering genetics!

Are Indica Genetics More Potent Than Sativa?

Should you opt for sativa or indica strains when purchasing high-THC marijuana seeds? While these labels help to describe the potential size and appearance of a cannabis strain, they do little to describe its flavour or effects. Instead, you should focus solely on the THC and terpene content of a strain to determine its power.

Does Skunk, Gelato, or Gorilla Genetics Contain the Most THC?

Skunk, Gelato, and Gorilla genetics are all famous for their high concentrations of THC. While they'll all scratch that psychoactive itch, Gorilla strains offer some of the highest THC values available.

How Do You Increase THC Before Harvesting?

All high-THC weed seeds are capable of churning out huge levels of the cannabinoid, but you need to help them along the way. Provide strong lighting, the right nutrients, and the proper quantities of water during the growing cycle to produce some truly potent cannabis.
