Indica is a category of Cannabis that originates from the Hindu Kush mountains of India and is believed to have a relaxing effect when consumed. Indica plants are typically shorter in stature with wide fan leaves. Indicas have a growth cycle between 8-12 weeks. Sativa strains originated in Central and South American and are believed to have an energizing effect once consumed. Sativa plants are tall and slim, with long narrow fan leaves. Sativas have a growth cycle between 10-16 weeks. Although licensed producers and the industry broadly utilize the Indica and Sativa classifications, due to generations of cross-breeding, arguably, all strains are now considered hybrids with Indica and Sativa weightings.
