Usually refers to female marijuana plants that have been cultivated outdoors in commercial quantities using basic agricultural techniques. This method of production results in low THC content and the presence of numerous seeds due to pollination by any male plants that are present.
Often originates from, and uses varieties of marijuana (Indigenous Land Races, or ILRs) indigenous to, Mexico, Jamaica, Thailand or South Africa, for reasons relating to location, climate and cultural attitudes to marijuana use and production.
Popularity and use vary geographically: in countries of origin, this kind of weed, sometimes loose and unpressed, is the staple marijuana product. In the affluent markets of North America and Europe, more powerful, higher quality, locally grown sensimilla (lit. 'seedless') and hashish are favoured. In hashish producing countries (Morocco, Afganistan, Nepal, India) hashish is the staple form of marijuana.
