High THC Seeds

Buy High THC Seeds in the UK 

Seed collectors have always wanted seeds with high THC levels.   

Tetrahydrocannabinol or THC is the main psychoactive component of cannabis and is responsible for the ‘high’ associated with the plant. Certain cannabis plants have been known to naturally provide high THC content; however, with the growing aid of technology, breeders have been able to identify ways to increase THC content in plants via cross-breeding.
