Sinsemilla, abbreviated sensi, is the fusion of duo Spanish terms — ‘Sin’ and ‘Semilla’ which means ‘Without’ and ‘Seeds’ respectively. Simply put, sinsemilla means the absence of seeds. Sinsemilla is a seedless cannabis flower obtained from unfertilized feminine plants. Sinsemilla is the most potent form of marijuana, which can be likened to a skunk because it possesses a very high amount of THC. It is neither a Sativa, Indica, or hybrid— the only aspect that counts when a plant is being termed a sinsemilla is that it must be feminized and unpollinated.
