A close relative of marijuana, sinsemilla is a flowering cannabis plant which is commonly far higher in concentration of tetrahydrocannibol. ("THC" The active drug in marijuana) Sinsemilla is the actual flowering portion of a cannabis plant, while marijuana is classified as vegitation (leaves). Conventional marijuana yields approximately 4% THC concentration, while sinsemilla is commonly between 10-14% concentration and if grown correctly will be seedless as well.
Sinsemilla is a combination of two spanish words "Sin" meaning "without" and "semilla" meaning "seed".
