Sativas are the opposite of indicas. Tall and thin marijuana plants with much narrower leaves and grow a lighter green in color. Sativas plants are originally from Southeast Asia, Mexico, Thailand and Colombia. Once flowering has begun, they can take anywhere from 10 to 16 weeks to fully mature. Flavors range from earthy to sweet and fruity. Getting stoned of a Sativa will get you cerebral, up and energetic.

Sativa is characterized by a tall growth habit, slender fingered leaves, a low flower to leaf ratio and rather long flowering period. When smoked, sativa gives a clear, up, cerebral high while indica produces a 'stonier' more physical hit. In the last few decades, enthusiasts have created sativa/indica hybrids which combine the best features of both varieties.
