Stackatrait™ Technology
Proprietary precision trait-stacking platform — 5 trait categories combined per variety
What is Stackatrait technology?
Stackatrait™ is Precision Plants' proprietary precision breeding platform that stacks multiple beneficial traits into a single hemp variety simultaneously. It uses targeted modifications to the plant's own genes across five trait categories — Cannabinoid Modification for THC elimination, Seed Yield & Oil for enhanced grain output, Fibre Quality for superior bast fibre, Root & Carbon for deep root architecture and carbon sequestration, and Climate Resilience for UK-optimised growing — producing varieties that are THC-free, disease-resistant, high-yielding, and climate-resilient in 3–5 years.
Each trait modification has functional precedent in major crops published in leading peer-reviewed journals. The platform is classified as precision breeding under the Precision Breeding Act 2023, meaning edited varieties follow a streamlined regulatory pathway in England. All modifications target the plant's own genes with no foreign DNA introduced. — Precision Breeding Act 2023
Precision Stacking Multiple Traits Into One Variety
Stackatrait™ is Precision Plants' proprietary precision breeding platform that enables multiple, precisely targeted trait modifications within a single hemp variety. Unlike traditional breeding which takes 10–15 years per variety and often loses traits during crossing, Stackatrait™ combines THC elimination, yield enhancement, fibre quality, root development, carbon sequestration, and climate resilience — all in one elite variety with 100% trait inheritance stability.
What is Trait Stacking?
Combining multiple precision trait modifications in a single variety
Traditional plant breeding is like trying to solve a Rubik's cube — fix one side and you often mess up another. When breeders cross plants to combine traits, they frequently lose desirable characteristics in the process. It can take 10–15 years to develop a single improved variety.
Stackatrait™ changes everything. Using precision breeding techniques, we make multiple targeted modifications to a plant's own genome simultaneously — without affecting other beneficial traits. No foreign DNA is introduced. Each modification has functional precedent in major crops published in leading peer-reviewed journals.

Elite UK hemp varieties
Five Trait Categories
Each category addresses a critical performance dimension. Categories are mixed and matched across varieties to create elite hemp lines optimised for specific markets.
Cannabinoid Modification
THC Elimination & Compliance by Design
Our proprietary cannabinoid modification permanently disables the biochemical pathway responsible for THC production. This precision approach ensures <0.01% THC in all plant tissues under all environmental conditions — eliminating compliance risk entirely and giving farmers extended harvest windows without regulatory concern.
Complete THC Elimination
Permanent disabling of the THC production pathway ensures plants are genetically incapable of exceeding legal limits
Stress-Proof Compliance
No THC spikes during drought, heat, or late harvest — zero crop destruction risk under any growing conditions
Extended Harvest Windows
Farmers can harvest at optimal timing for yield and quality without regulatory risk
All Varieties Protected
BritGrain Auto (THC-free grain), YieldMax Duo (extended dual-harvest), LongLine Fibre (safe flowering harvest)
Seed Yield & Oil Quality
Maximising Grain Output & Premium Oil Profiles
Multiple precision trait modifications work together to maximise grain yield and oil quality. Our approach increases seed size and weight, boosts seed number per plant, prevents seed shatter for near-complete harvest efficiency, and produces premium high-oleic oil profiles suitable for food, health, and cosmetic markets.
Enhanced Seed Size & Weight
Significantly larger, heavier seeds with higher oil content per seed — targeting 22–27g per 1000 seeds
Increased Seed Number
Enhanced inflorescence branching produces more seeds per plant, boosting overall grain yield per hectare
Shatter Resistance
95–98% harvest efficiency by preventing premature seed drop — eliminates the largest single source of grain loss
Premium Oil Profile
High-oleic oil composition (>70% oleic acid) for extended shelf life and premium food/cosmetic positioning at £50–100/t premium
Fibre Quality & Processing
Superior Bast Fibre for Textiles & Composites
Targeted modifications to fibre architecture, lignin content, and cell wall composition optimise bast fibre content, tensile strength, and processing efficiency. Reduced lignin increases the cellulose proportion to 70–78%, while improved cell wall composition cuts retting time by 50% — critical for UK's damp autumn conditions.
Enhanced Bast Fibre Content
30–35% bast content (industry-leading); 2.4–3.5 t/ha bast fibre extracted; 1.2–1.8 t/ha textile-grade
Improved Fibre Strength
500–720 MPa tensile strength (+30% vs baseline); improved flexibility for textile spinning and composite reinforcement
Accelerated Retting
2–3 week retting time (vs 4–6 weeks baseline); 50% faster processing; critical for UK damp autumn conditions
Optimised Biomass Architecture
2.5–3.5m plant height; 8–12 t/ha dry straw; 2–3m primary bast fibre length for textiles
Root Architecture & Carbon Sequestration
Deep Rooting for Drought Resilience & Carbon Revenue
Enhanced root architecture produces deep taproots with increased lateral root density, dramatically improving drought resilience and subsoil nutrient access. The enhanced root biomass and organic matter deposition increase soil carbon storage to 8–15 t CO₂/ha annually — opening a significant new revenue stream through carbon credit markets.
Deep Root Architecture
2–3 metre taproots for drought resilience and subsoil nutrient access — far exceeding conventional hemp root depth
Carbon Sequestration
8–15 t CO₂/ha sequestered annually — comparable to young woodland and significantly above arable crop baselines
Carbon Credit Revenue
Eligible for UK Woodland Carbon Code and voluntary markets at £30–50/t CO₂ (£240–750/ha additional revenue)
Soil Structure Improvement
Root architecture breaks compaction, improves drainage, and reduces erosion — leaving soil in better condition for following crops
Climate Resilience
UK-Optimised Growing Season & Weather Tolerance
A suite of climate adaptation traits reduces the germination threshold to ~8°C (enabling mid-April sowing across most UK regions), creates auto-flowering behaviour optimised for UK latitudes (50–58°N), ensures uniform maturity for single-pass mechanical harvest, and provides lodging resistance for stable stands even in high-wind conditions.
Cold Tolerance
Germination at 8°C (vs 12°C standard); mid-April sowing; 3–4 week extended growing season across UK regions
Photoperiod Optimisation
Auto-flowering genetics optimised for UK latitude (50–58°N); eliminates photoperiod dependency for reliable maturation
Maturity Synchronisation
90–140 day predictable maturity range; uniform ripening for single-pass mechanical harvest
Lodging Resistance
Sturdy stem architecture with <3–5% lodging losses even in high-wind conditions — critical for UK weather

THC Elimination: Removing Compliance Risk
The foundation of every Precision Plants variety — permanent THC pathway disabling
The Problem with EU Varieties
Current EU hemp varieties can spike above 0.2% THC under UK growing conditions. If this happens during the Home Office inspection window, the entire crop must be destroyed — regardless of investment or contracts.
How THC Elimination Works
Pathway Identification
We identify the biochemical pathway responsible for converting precursor compounds into THC — the enzyme that produces the psychoactive compound.
Precision Modification
Using precision breeding techniques, we make a targeted modification that permanently disables the THC production pathway — rendering it non-functional.
Permanent Elimination
Without a functional THC production pathway, the plant physically cannot produce THC — achieving <0.01% THC even under extreme stress conditions (drought, heat, late harvest).
