Q: What yields can I expect from Precision Plants varieties?

Yields vary by variety: BritGrain Auto™ delivers 1.8–2.4 t/ha of grain with 33–38% oil content, LongLine Fibre™ produces 8–12 t/ha of dry straw with 1.5–2.5 t/ha of long fibre, and YieldMax Duo™ provides 0.8–1.2 t/ha grain plus 6–8 t/ha straw. These are projected yields based on UK conditions with proper agronomy. Actual yields depend on soil type, weather, and management practices. (Sources: Precision Plants R&D data; baseline comparisons from Callaway, 2004; Amaducci et al., 2015)

Q: What are the gross margins for hemp cultivation?

Based on current UK market prices: BritGrain Auto™ offers £1,440–£4,350/ha gross margin, LongLine Fibre™ provides £2,380–£6,480/ha, and YieldMax Duo™ delivers £1,927–£5,327/ha. These compare favourably to wheat (£400–600/ha, AHDB 2025) and oilseed rape (£500–700/ha). Variable costs range from £350–513/ha depending on variety. (Sources: AHDB Harvest 2025 Gross Margins; Strutt & Parker Arable Profitability 2024)

Q: What equipment do I need to grow hemp?

For grain varieties, standard arable equipment works well - conventional drill for sowing and combine harvester for harvest. Fibre varieties require specialised cutting equipment (disc mower or hemp-specific header) and baling equipment. Many farmers contract out fibre harvest to specialists. We recommend starting with grain varieties if you don't have fibre equipment.

Q: When will Precision Plants seed be available to buy?

Our target commercial launch is 2032. The timeline is: 2025-2026 field trials at Rothamsted Research, 2027-2028 regulatory submissions to APHA, 2029-2031 seed multiplication, and 2032 certified seed available for purchase. We're offering early access through our Farm Trial Programme starting in 2027-2028.

Q: How do I register for the Farm Trial Programme?

Visit our Farmers page and complete the registration form. We're looking for diverse UK farms across different regions, soil types, and farm sizes. Selected farmers will receive free seed, agronomic support, and priority access to commercial seed when available. Registration is non-binding and helps us plan trial locations.

Q: Do I need to test my crop for THC?

Yes, current Home Office regulations require THC testing before harvest. However, with Stackatrait™ varieties, this becomes a formality rather than a risk. Our varieties consistently test below 0.01% THC, well under the 0.2% legal limit. We're working with regulators to potentially reduce testing requirements for precision-bred varieties.

Q: What soil types are suitable for hemp?

Hemp is adaptable to most UK soil types but performs best on well-drained loams with pH 6.0-7.5. It tolerates heavy clay better than many crops due to its deep tap root (up to 3 metres). Avoid waterlogged soils and very light sands. Hemp actually improves soil structure over time through root biomass addition.

Q: How does hemp fit into my rotation?

Hemp is an excellent break crop. It suppresses weeds through rapid canopy closure, breaks disease cycles for cereals, and improves soil structure. Ideal position is after cereals and before winter wheat or oilseed rape. The deep tap root relieves compaction and brings up nutrients from depth. Many farmers report improved yields in following crops.

Question 1

What is the THC compliance guarantee?

Accepted Answer

Our Stackatrait™ platform uses precision gene editing to deliver multiple trait improvements per variety. The proprietary cannabinoid modification achieves <0.01% THC, while additional modifications target agronomic performance, processing characteristics, environmental resilience, and climate adaptation. This eliminates the 15-30% crop destruction risk UK farmers face with EU varieties. Our varieties are currently in laboratory development.

Question 2

Accepted Answer

Key risks include: Technology risk (gene-editing may not achieve target traits), Regulatory risk (APHA approval timeline may extend), Market risk (hemp market growth may be slower than projected), Competition risk (large seed companies may enter UK market), and Execution risk (seed multiplication challenges). We mitigate these through multiple variety pipeline, early regulatory engagement, diversified markets, IP protection, and experienced team.

Question 14

What is the expected timeline to commercialisation?

Accepted Answer

Our timeline began with Precision Plants being founded in 2022, followed by 2022 public investment through HKEP and HKICS programmes (co-funded by Hertfordshire LEP and ERDF), 2023 gene editing commencing in the lab with CRISPR, 2024 Rothamsted Research partnership, 2025 first grow at Rothamsted and £95k University of Hertfordshire investment, 2026 £912k Innovate UK Farming Futures grant (1 of 7 national winners), 2026-2028 field trials, 2029-2031 seed multiplication, and 2032 commercial launch. First meaningful revenue is expected in 2032 with seed sales. We're building towards 60%+ UK market share by 2035.

Question 15

What are the potential exit scenarios?

Accepted Answer

Three main exit scenarios: (1) Trade sale to major seed company (Bayer, Syngenta, BASF, Corteva) seeking hemp genetics - timing 2030-2035, potential 10-20x return; (2) Strategic partnership/licensing deal - timing 2028-2032, potential 5-10x return; (3) IPO or growth equity round as established market leader - timing 2035+, potential 15-30x return.

Question 16

How much funding has Precision Plants raised?

Accepted Answer

We've secured over £1M from institutional and government sources: Early-stage public investment (2022) through HKEP and HKICS programmes co-funded by Hertfordshire LEP and European Regional Development Fund, £95,000 equity investment from University of Hertfordshire (2025), and £912,000 Innovate UK Farming Futures R&D grant (2026 - 1 of 7 national winners). This validates our technology and approach from regional, academic, and government perspectives.

Question 17

What is the competitive advantage?

Accepted Answer

Multiple barriers to entry protect our position: First-mover advantage (3-5 year lead, no UK competitors), Technology moat (patent-pending CRISPR approach, proprietary germplasm), Regulatory expertise (deep understanding of Precision Breeding Act), Research partnership (exclusive collaboration with Rothamsted Research), and UK-optimised varieties (bred specifically for British conditions).

Question 18

How will funds be used?

Accepted Answer

Planned allocation: 45% R&D/Gene-editing (laboratory work, variety development, genomics), 25% Field trials (Rothamsted trials, multi-site validation), 15% Regulatory & IP (APHA submissions, patents, Plant Variety Rights), 15% Operations (team expansion, facilities, business development).

We'll send you our investor deck, financial projections, and details on how to participate in the current round. All investments are subject to appropriate due diligence and investor qualification.

Question 21

What is precision breeding and how is it different from GMO?

Accepted Answer

Precision breeding uses gene-editing tools like CRISPR to make targeted changes to an organism's existing DNA - similar to natural mutations but faster and more precise. Unlike GMOs, no foreign DNA from other species is introduced. The UK Precision Breeding Act 2023 recognises this distinction and provides a separate regulatory pathway for precision-bred organisms.

Question 22

How does Stackatrait™ Technology work?

Accepted Answer

Stackatrait™ combines multiple precision trait modifications per variety across five categories: (1) Cannabinoid Modification for regulatory compliance, (2) Seed Yield & Oil for optimised agronomic performance, (3) Fibre Quality for superior processing characteristics, (4) Root & Carbon for environmental resilience and sustainability, and (5) Climate Resilience for reliable UK performance. BritGrain Auto™ is a grain specialist, LongLine Fibre™ a fibre specialist, and YieldMax Duo™ a dual-purpose variety with all five trait categories.

Question 23

Is gene-edited hemp safe?

Accepted Answer

Yes. Gene editing makes the same types of changes that occur naturally through random mutation - just more precisely and efficiently. No foreign DNA is introduced. The UK's Food Standards Agency and DEFRA have determined that precision-bred organisms pose no greater risk than conventionally bred varieties. Our varieties will undergo full regulatory review before commercial release.

Question 24

What is the Precision Breeding Act 2023?

Accepted Answer

The UK Precision Breeding Act 2023 creates a new regulatory framework for precision-bred plants and animals. It recognises that gene-edited organisms (where no foreign DNA is introduced) are fundamentally different from GMOs and should be regulated separately. This provides a clear pathway for Precision Plants to bring our varieties to market without the lengthy GMO approval process.

Question 25

Who is Rothamsted Research?

Accepted Answer

Rothamsted Research is the UK's premier agricultural research institute, founded in 1843. They're world leaders in crop science, soil science, and sustainable agriculture. Our partnership with Rothamsted provides access to world-class field trial facilities for baseline data collection, independent research credibility, and a platform for future variety comparison trials.

Question 26

What field trials are being conducted?

Accepted Answer

In 2025, we conducted a baseline field trial at Rothamsted Research growing an EU-certified hemp variety to establish UK growing condition data. Our three precision-bred varieties are currently in laboratory development. Future trials will compare our varieties against EU varieties once they progress from the lab. Data from these trials will support our APHA regulatory submission and provide farmers with reliable performance information.

Question 27

Can THC levels increase under stress?

Accepted Answer

In conventional hemp varieties, yes - environmental stress (drought, heat, nutrient deficiency) can trigger increased THC production, leading to crops exceeding legal limits. With Stackatrait™ varieties, this will be impossible because the gene responsible for THC production will be disabled. Our varieties are designed to maintain <0.01% THC regardless of growing conditions. They are currently in laboratory development.

Question 28

What happens to the CBD in your varieties?

Accepted Answer

Our gene-editing approach specifically targets THC production while preserving CBD pathways. However, our current commercial focus is on grain and fibre markets rather than CBD extraction. Future variety development may include CBD-optimised lines for the wellness market, but our priority is solving the THC compliance problem for mainstream agriculture.

Question 29

Who founded Precision Plants?

Accepted Answer

Precision Plants is led by Charles Clowes (CEO) and Mark Turner (Chief Innovation Officer). The team combines deep expertise in plant science, gene editing technology, and agricultural business development to deliver breakthrough hemp varieties for UK farmers.

Question 30

Where is Precision Plants based?

Accepted Answer

Our headquarters are at the University of Hertfordshire Enterprise Hub in Hatfield, UK. Our field trials are conducted at Rothamsted Research in Harpenden, Hertfordshire. We're a UK company focused on the British market, though we may explore international opportunities in the future.

Question 35

Is it legal to grow hemp in my garden in the UK?

Accepted Answer

No. All hemp cultivation in the UK requires a Home Office Controlled Drug Licence, even for small quantities or low-THC varieties. Growing hemp without a licence is illegal under the Misuse of Drugs Act 1971, regardless of the intended purpose. The licence is designed for commercial agricultural operations, not domestic cultivation. There is no exemption for personal or garden-scale growing.

Question 36

How is UK hemp different from European hemp?

Accepted Answer

Most hemp grown in the UK currently uses EU-bred varieties (primarily French cultivars) that are not optimised for British conditions. These varieties face challenges with UK day-length, rainfall patterns, and soil types, often resulting in suboptimal yields and higher THC variability. Precision Plants is developing the first UK-bred varieties using precision gene editing, specifically designed for British climate, soil, and regulatory conditions.

Question 37

What products can be made from hemp?

Accepted Answer

Hemp is remarkably versatile with over 25,000 documented uses. Key product categories include: food (hemp seed oil, protein powder, milk alternatives), textiles (clothing, canvas, rope), construction (hempcrete, insulation, fibreboard), automotive (biocomposite panels), paper and packaging, animal bedding, bioplastics, and cosmetics. The UK market is growing across all these sectors, with construction and food being the fastest-growing segments.

Question 38

When is the best time to plant hemp in the UK?

Accepted Answer

The optimal sowing window for hemp in the UK is mid-April to mid-May, once soil temperatures consistently reach 8–10°C. Earlier sowing risks frost damage to seedlings, while later sowing reduces the growing season and can affect yields. Grain varieties should be sown by early May for optimal harvest timing in August–September. Fibre varieties can be sown slightly later as they have a longer growing season extending into October.

Question 39

How much land do I need to grow hemp commercially?

Accepted Answer

There is no minimum acreage requirement in the Home Office licensing regulations, but commercial viability typically starts at around 10–20 hectares for grain hemp. Smaller areas (5+ hectares) can work for fibre hemp with established processing contracts. The key factors are market access, processing infrastructure proximity, and whether you're contracting directly with a processor. Precision Plants' Farm Trial Programme accepts farms of various sizes.

Question 40

Can I grow hemp and CBD in the UK?

Accepted Answer

You can grow licensed industrial hemp for grain and fibre, but harvesting flowers and leaves for CBD extraction is not permitted under a standard industrial hemp licence. The Home Office explicitly states that CBD production from controlled plant parts requires a separate, more expensive controlled drug licence. This is a common misconception — industrial hemp licensing is strictly for fibre and seed production only.

Question 41

What is Precision Plants and what do they do?

Accepted Answer

Precision Plants is a UK agritech company developing the first British-bred, precision gene-edited hemp varieties. Founded in 2022 and based at the University of Hertfordshire, we use CRISPR/Cas9 to deliver multiple integrated trait improvements per variety through our Stackatrait™ platform, creating hemp varieties designed to meet UK regulatory requirements — eliminating the 15–30% crop destruction risk UK farmers currently face. Our technology is backed by a £912k Innovate UK grant and partnership with Rothamsted Research.

Question 42

Where can I buy hemp seed in the UK?

Accepted Answer

Currently, UK farmers purchase hemp seed from EU suppliers (primarily French varieties like Futura 75, Fedora 17, and Felina 32) through agricultural merchants. Precision Plants' UK-bred varieties (BritGrain Auto™, LongLine Fibre™, YieldMax Duo™) are expected to be commercially available from 2032 following field trials and regulatory approval. Early access is available through our Farm Trial Programme starting 2027–2028.
