White Widow is one of the best-known and still one of the most potent cannabis strains globally. Initially created in the early 1990s, its release to the coffee shops of Amsterdam was met with universal rave reviews as canna-tourists flocked in their thousands to find out whether all the advance publicity for this white strain was proper. It was and remains so today. It is bred by crossing a Brazilian sativa strain with a highly resinous South Indian indica; it is named after the plant's frosty appearance, making it white with resin.  How White Widow Grows  It is an easy strain to grow almost anywhere; its eight-week flowering period ensures that it will be ready to harvest outdoors in October in northern latitudes before the weather gets too cold. THC levels are high, around 20%.  White Widow Tastes, Smell, and Effect White Widow is designed for the utmost potency rather than any complex taste profile, although the effect is smooth and satisfying. The initial hit comes on fast and strong, leaving anyone but the most experienced user to sit down. This slowly evolves into a very relaxing high ideal for enjoying music.¬â€
