Indica-dominant strains are hybrid genetics that are created when indica and sativa strains are crossed. This certain type of strain leans more toward the indica side in terms of its growth pattern and the effects it has on the end user. Indica-dominant strains of cannabis are known for their ability to produce deep cerebral euphoria and a strong body high.
