Do-Si-Dos, formerly known as CI #5 F1, is an award winning Indica dominant strain. This strain is well received by growers, medical patients, and recreational consumers and may be one of the most popular Indica strains of all time.Known by many as a two hit and quit strain, Do-si-Dos slams the body into a wonderfully numbing, lazy mode. The desire to sit on the couch and listen to the call of munchies may be overwhelming to novice users even in lower doses.
