High THC Cannabis Strains

High THC

Tetrahydrocannabinol or THC is the primary psychoactive cannabinoid compound of the plant we all love. With the latest breeding techniques, and a vast range of high-quality genetics, the average THC level in our premium strains is higher than ever. This collection is perfectly suited to those looking to add a powerhouse to their garden. Not only are these strains almost all 20% THC or greater, but they all also have well-rounded terpene profiles and moderate to high yields.
