- Also called “indo.” While the etymology is hard to pin down, most agree that it generally refers to cannabis plants that are grown indoors using hydroponic systems. Indoor-grown cannabis is favored over plants grown outdoors by many since temperature and weather control results in a consistently high-quality product. In fact, high-quality weed is often called endo as slang. This term can also be used as a shortening of the “endocannabinoid system,” but this is not as common.
