A guide to high-THC strains

A guide to high-THC strains

Are you looking to purchase cannabis seeds with extreme THC levels? Well, you’re about to discover some of the best strains to suit your desires. However, before we introduce you to our superstar weed varieties, we think you’ll find this brief guide helpful for your cultivation endeavours. Below, find out the key benefits of growing strains loaded with THC, and how to raise them.

Benefits of strains with a high THC content

Why do growers choose to cultivate high-THC strains in the first place? Well, part of the answer is quite obvious: they contain more THC! Higher quantities of the psychoactive cannabinoid means it takes less plant material to experience equally potent effects. With weaker varieties, many experienced smokers might need a whole joint to feel suitably high, whereas with a high-THC strain, a single bong hit might suffice. Overall, a stash of high-THC flowers lasts longer. Those with a particularly high tolerance can also use them to make extremely powerful edibles and extracts to really scratch their itch.

Growing cannabis with higher THC levels

You might think that growing high-THC cannabis takes some kind of special approach—but you’d be mistaken. You can grow these plants in the same way as other varieties. Strains high in THC are innately “wired” to churn out much higher quantities of the cannabinoid. However, this doesn’t mean you can get away with taking shortcuts. Ultra-potent plants still depend on powerful lights, high-quality organic nutrients, and a mindful watering schedule to express their full genetic potential.

Buy the best high-THC genetics available
