T.H. Seeds – a Dutch legend of cannabis genetics

T.H. Seeds is one of the oldest and most respected seed banks in the cannabis world, setting standards for quality, stability, and innovation in cannabis breeding for over 30 years. The brand was founded in Amsterdam in 1993 by brothers Adam and Doug as part of C.I.A. (Cannabis In Amsterdam)—a famous cannabis information center and seed shop that became a true epicenter of European cannabis culture.

Brand history and philosophy

T.H. Seeds is more than a seedbank—it’s an institution that from the beginning has combined old-school genetics with a passion for new, innovative crosses. The brand built a strong position through the philosophy “To Protect Genetics and Serve Mankind”—protecting genetics and delivering them to the community of breeders and enthusiasts worldwide.

In its early years, T.H. Seeds was already present on the scene of legendary cannabis competitions, including the popular High Times Cannabis Cup, and many of its varieties won awards for both flowers and hash. The brand was also one of the first to be inducted into the High Times Seedbank Hall of Fame, an important industry distinction.
