Hemp Hurd Fiber: A Viable Substitute for Peat Moss in Container Production of Horticultural Crops   Growers are interested in alternative, sustainable substrates to replace peat moss due to rising costs and awareness of the environmental damage caused by peat mining. Cultivation of hemp (Cannabis sativa) in the United States for the textile industry is expanding. A significant byproduct of hemp stem manufacturing is hurd, which consists of fibers that are too short for textile use. The feasibility of using hurd as a substitute for peat in the production of a range of crops, including potted flowering plants, vegetables, and ornamental shrubs and herbaceous perennials, was explored.
