Advancing British Hemp with Precision—By Design

Precision Plants is the UK’s dedicated specialist in next-generation hemp genetics. We believe that the full promise of Cannabis sativa L.—as a foundation for sustainability, rural prosperity, and new green industries—will only be realised when British farmers and supply chains can rely on modern, compliant, and truly fit-for-purpose seed.

Founded in 2021, Precision Plants brings together pioneers of British hemp cultivation, world-class plant geneticists, and leading supply chain partners. Our company exists for one clear purpose: to make the UK a leader in science-backed, reliable, and climate-ready hemp—on British terms, for British farmers and industries.


Our Mission

Our mission is as precise as our breeding:

To deliver industry-defining, precision-edited hemp seed (Cannabis sativa L.)—bred, validated, and certified for UK conditions and regulations—so farmers, processors, and the wider bioeconomy can prosper with certainty, not risk.

Through specialist gene editing, digital traceability, and deep sector partnerships, we are removing the “fear factor” that has long hampered British hemp—and building a backbone for the nation’s next green transition.


What Sets Us Apart

  • UK-Bred, UK-Tested Hemp—Only:
    Unlike importers or generic breeders, every one of our varieties is engineered from the ground up for British soils, light, and policy. Our unique focus on hemp ensures deep expertise—no distractions, no crop dilution, just Cannabis sativa L. done right.
  • Gene Editing for Real-World Benefit:
    Precision Plants harnesses advanced tools like CRISPR/Cas9, rapid trait stacking, and molecular validation. We go far beyond conventional breeding, assembling critical traits—ultra-low/zero THC, high yield, premium grain and fibre, storm resilience—specifically demanded by British growers and processors.
  • Compliance, Guaranteed:
    Our flagship lines (like THC-Free Hemp) guarantee strict adherence to the UK’s 0.2% THC law, eliminating the uncertainty and regulatory risk that comes with “continental” imports. Legal security isn’t an add-on; it’s built in from seed to contract.
  • Digital “Seed Passports”:
    Every Precision Plants seed batch carries a cryptographically secure digital passport, documenting origin, field history, and compliance. No more lost paperwork—just instant, auditable transparency for growers, buyers, and regulators.
  • True Collaboration:
    We are trusted advisors and innovation partners to leading British research institutes (University of Hertfordshire, Rothamsted Research) and grower associations (British Hemp Alliance, Scottish and NI Hemp Associations). Every variety comes from—and feeds back into—real farm, processor, and market needs.

Our Flagship Hemp Projects

  • BritGrain Auto™:
    The UK’s first precision-bred, “compliance by design” grain hemp—empowering domestic protein and food markets with confidence and predictability.
  • LongLine Fibre™:
    Bringing homegrown, high-quality fibre to the UK’s construction, composites, and textile sectors with climate-resilient genetic innovations and supply chain certainty.
  • YieldMax Duo™:
    Dual-purpose hemp giving farmers flexibility: strong yields in grain and fibre, all in a single, regulation-ready variety.
  • StormGuard™:
    Stacking climate resilience so that British hemp withstands storm, drought, and flood—protecting yields and rural investments as weather volatility increases.

Each project is anchored in British fields, proven and refined in partnership with growers and end-users, and underpinned by open science, knowledge-sharing, and compliance excellence.


Our Vision

We see a future where Cannabis sativa L.—British-bred and British-proven—anchors rural rotations, powers sustainable supply chains, and supports profitable, net zero-ready farming from Cornwall to Cumbria.

By 2030, Precision Plants aims to be the trusted UK supplier of certified, precision-edited hemp—scaling 80,000+ hectares of innovation, opportunity, and climate action.
