High-THC Cannabis Seeds — the strongest strains from Pyramid Seeds

Looking for cannabis strains with high THC? Our most potent genetics deliver 25 to 30% THC — from the flagship Tutankhamon (lab-verified up to 33% THC) to the complete Gold Line range. All high-THC seeds with a germination guarantee, direct from the breeder, with fast, discreet worldwide shipping.

What are high-THC cannabis seeds?

THC (tetrahydrocannabinol) is the main psychoactive cannabinoid in the cannabis plant. High-THC cannabis seeds come from genetics specifically selected for maximum THC production. While standard strains usually sit between 15 and 20%, the strongest strains in the Pyramid Seeds range reach 25 to 30% THC — with Tutankhamon lab-verified as high as 33%. How much of that genetic potential ends up in the buds depends on light intensity, nutrition and, above all, the right harvest timing.
