At Maverick Genetics, we specialise in high THC cannabis seeds designed for growers who want top-tier potency, bold flavours, and impressive harvests. Our collection is handpicked to satisfy both experienced cultivators and adventurous connoisseurs.

What is THC and why does it matter?

THC, short for tetrahydrocannabinol, is the main psychoactive component in cannabis. It’s what delivers the euphoric effects associated with a cannabis high. Through expert breeding and careful selection, certain strains have been developed to contain extremely high THC levels making them favourites among those who want strong effects, whether for recreational or medicinal use.
