Since 1995, our "Head Quarters", has been located at Hemp Works in the heart of Amsterdam. Before this, we were located at infamous C.I.A. (Cannabis In Amsterdam), which we opened in 1993. Since the beginning, T.H.Seeds has relied heavily on customer feedbacks in order to improve our line of seeds. We have been working primarily with 10 strains. These strains not only have proved to be very popular with growers but have also won numerous awards.
