Big Sioux operates through Dakota Herb's vertically integrated system, with cultivation facilities in Brandon and Lincoln County producing both Big Sioux Bud flower products and Big Sioux Extracts concentrates. The company maintains dispensary locations in Brandon, Aberdeen, Vermillion, and Huron, serving medical cannabis patients throughout South Dakota.The Big Sioux product portfolio spans two main categories: Big Sioux Bud offers premium cannabis flower and pre-rolls, while Big Sioux Extracts specializes in concentrates including distillate vape cartridges, RSO (Rick Simpson Oil), and raw distillates. All cannabis is grown indoors in climate-controlled environments using rockwool growing cubes, with precise nutrient delivery systems ensuring consistent quality and potency.The cultivation process emphasizes cloning from proven mother plants rather than seed propagation, ensuring genetic consistency and reliable THC levels across harvests. With both facilities operational, Dakota Herb forecasts weekly harvests of 125 pounds of flower, supporting steady product availability. Quality standards are maintained through the founding team's combined expertise in production agriculture, law enforcement, and logistics.
Big Sioux emerged from Dakota Herb, a Brandon-based cannabis company founded by CEO Dalton Grimmius, who brought his traditional farming background into the medical cannabis space in 2021. What started as a way to diversify a family farming operation has grown into one of South Dakota's pioneering cannabis brands, with Grimmius applying decades of agricultural expertise to cannabis cultivation.The company quickly expanded from its original Brandon facility to multiple locations across South Dakota, including Aberdeen, Vermillion, and Huron, establishing itself as a key player in the state's emerging medical cannabis market. A major milestone came in 2023 when Dakota Herb partnered exclusively with actor and cannabis advocate Jim Belushi's Belushi's Farm, bringing celebrity-endorsed strains to South Dakota patients.Big Sioux has achieved several industry firsts, including opening the first medical marijuana dispensary in Aberdeen and being among the earliest licensed operators in South Dakota's medical program. The brand has grown from a single facility to a vertically integrated operation with multiple dispensaries and cultivation sites across the state.
