Fibre Hemp

Fibre hemp refers to Cannabis sativa cultivars selectively bred for high cellulose and bast fibre production rather than cannabinoid yield. These varieties are characterized by tall, sturdy stems with minimal branching and are grown commercially for textile, paper, construction, and composite material applications. Fibre hemp genetics prioritize stem strength, plant height, and fibre quality over flower development. Most fibre hemp varieties contain negligible THC levels and fall under legal definitions of industrial hemp in jurisdictions permitting cultivation. The category encompasses both pure fibre-type landraces and modern cultivars developed through targeted breeding for agronomic performance and fibre properties.

Breeders working in fibre hemp focus on stem diameter consistency, fibre fineness and length, plant uniformity for mechanical harvesting, and disease resistance rather than potency or terpene profiles. Modern fibre cultivars are often improved through selection for deterministic plant architecture, reduced lodging risk, and optimal maturity timing for harvest window consistency.
