Leading UK Salad Grower:
Commercial Hydroponic Growing System Transformation
A £30M revenue salad operation with a fundamental problem: the production system was not delivering the yield, quality, or market positioning that the scale of the business required. Replacing it meant integrating new and existing systems without disrupting an operation that couldn't afford to stop producing.
Saturn Bioponics transformed a 1.2Ha Worcestershire salad facility from soil-based growing to high-intensity hydroponic production over an 8+ year relationship — with the major installation completed in 2021. The project achieved up to 6x lettuce production increase, 4.9x Pak Choi improvement, multi-year retail contracts and premium category wins with major UK retailers, and opened entirely new herb revenue streams — through the installation of Saturn Grower systems and Autogrow Multigrow, integrated with the client's existing Priva environmental control infrastructure.

The Challenge: A Scale Operation Constrained by Its Production System
At £30M revenue, this Worcestershire salad grower was operating at commercial scale — but the production system was holding the business back. Soil-based growing methods, both in greenhouse and outdoor field production, were generating yields well below what modern hydroponic alternatives could achieve. Disease pressure was reducing saleable crop percentages. Food safety and quality consistency were limiting access to premium retail categories. And the crop portfolio was restricted to what the existing system could reliably produce.
The transformation required was not a simple system upgrade. It was a complete conversion of the production methodology, integrated with existing infrastructure that represented a substantial capital investment, delivered without disrupting the ongoing commercial operation. Saturn Bioponics had been working with the business since 2016 — the trust required to take on a project of this scale was already established.
Pre-Transformation Constraints
Low planting density and limited annual cycles reducing total production per square metre
Soil-borne disease pressure reducing saleable crop percentages and increasing production losses
Quality variability preventing access to premium retail Finest category contracts
Crop portfolio limited to lettuce and Pak Choi — no viable herb production capability
Poor greenhouse infrastructure utilisation relative to the capital investment it represented
Food safety compliance limitations relative to the standards major retailers increasingly required
The Solution: Integrated Transformation of a Live Commercial Operation
Saturn Bioponics delivered a complete turnkey hydroponic system across the 1.2Ha facility — installing the complete hydroponic system into a new greenhouse facility, and integrating it with the client's existing Priva environmental control infrastructure from their wider operation. Making Autogrow Multigrow and Priva work together as a single system — two platforms not designed to interoperate — was the central technical challenge of the project.
Saturn Grower Tower System — Maximum Space Utilisation
The Saturn Grower vertical tower system provided the high planting density and production cycle frequency required to achieve the step-change in yield. The four-zone crop area design provided operational flexibility — enabling different crops, protocols, and growing conditions to be managed independently across the facility, and allowing phased introduction of new crop varieties without disrupting core production.
Control System Integration — Autogrow and Priva
Saturn Bioponics installed Autogrow Multigrow as the hydroponic nutrition and irrigation management system, and integrated it with the client's existing Priva environmental control infrastructure. Priva is a capable greenhouse environment platform but operates as a relatively closed system — integrating it with Autogrow required a carefully designed interface approach. Saturn blended the two: Priva managing greenhouse environmental control and heating, Autogrow handling hydroponic nutrition and irrigation, with a universal sensor network bridging both systems to create complete cultivation parameter visibility across the facility. The result was a single operational system, with the data architecture for remote support and ongoing optimisation.
Sustainable Infrastructure Integration
Beyond the hydroponic systems, Saturn Bioponics integrated biomass heating and energy supply, rainwater collection and treatment systems feeding into the irrigation network, and all facility services within the single project scope. This comprehensive integration approach — one partner managing the complete system — eliminated the interface complexity and accountability gaps that multi-supplier projects create.

Commercial Results
The transformation produced measurable improvements across every commercial dimension the client needed to address — yield, quality, market position, and crop diversity.
Before — Soil-Based Production
Lettuce
18 plants/m²/year — outdoor field production
Pak Choi
90 saleable heads/m²/year — soil greenhouse, 75% saleable
Herbs
No viable production capability
Retail access
Seasonal contracts only — no multi-year supply agreements
After — Saturn Hydroponic System
Lettuce
Up to 6x production increase — higher density, more cycles
Pak Choi
4.9x improvement — 95% saleable, higher planting density
Herbs
Basil and parsley — new profitable revenue streams
Retail access
multi-year retail contracts and premium category wins — major UK retailers
The herb programme delivered a particularly significant commercial outcome. Basil production achieved 2.6kg/m² per cut across multiple annual cycles — a crop the existing system could not produce competitively, now generating an entirely new revenue stream that diversified the business's market position and reduced dependence on the core salad categories. The retail relationship improvement — from standard category to multi-year retail contracts and premium category wins — changed the commercial structure of the business at the top line, not just at the cost level.
Frequently Asked Questions
Questions from commercial growers considering hydroponic conversion or system integration.
What yield improvements can a commercial grower expect from converting soil production to hydroponics?
Yield improvements from soil-to-hydroponic conversion depend on the baseline production system, crop types, and the hydroponic system design. At the leading UK salad grower project, Saturn Bioponics achieved up to 6x lettuce production increase and 4.9x Pak Choi improvement. These figures reflect the combined effect of higher planting density, more production cycles per year, and dramatically improved saleable crop percentage through better disease management and quality consistency. The conversion also enabled entirely new herb crop revenue streams not viable in the prior system.
How do you integrate a new hydroponic system with existing greenhouse control infrastructure like Priva?
Integrating with existing control systems such as Priva requires a layered approach. Priva operates as a relatively closed system — it excels at greenhouse environmental control but has limited data visibility for hydroponic nutrition and irrigation management. Saturn Bioponics integrated Priva for its core environmental function while adding Autogrow Multigrow for hydroponic nutrition and irrigation management, and a universal sensor network to create complete cultivation parameter visibility. This preserved the client's existing infrastructure investment while delivering the precision hydroponic control capability the new system required.
What is required to secure premium retail Finest category contracts for fresh salad crops?
Premium retail category contracts require consistent crop quality, food safety standards meeting retailer specification, supply reliability across the year, and traceability documentation demonstrating compliance throughout the production chain. Soil-based growing creates inherent quality variability and food safety risk — particularly from soil-borne disease pressure — that makes consistent premium specification difficult to achieve. The conversion to hydroponic production eliminated the primary sources of quality variability, enabling this salad grower to achieve multi-year retail contracts — a step change from the seasonal contracts that had previously been the limit of their retail relationships — alongside premium category wins with major UK retailers.
How is a commercial hydroponic system financed alongside a large existing growing business?
Major hydroponic system investments for established growing businesses are typically structured through a combination of business capital and external equipment financing. The leading UK salad grower project was delivered in partnership with an external financing provider, with Saturn Bioponics coordinating the technical specification and delivery alongside the financing structure. This enabled the client to commit to the full transformation without requiring the total capital outlay upfront, with the production improvements generating the revenue to service the financing from the first growing season.
Can a legacy greenhouse be converted to hydroponic production without rebuilding from scratch?
Yes — and the leading UK salad grower project demonstrates this directly. Saturn Bioponics installed Autogrow Multigrow and the complete Saturn Grower hydroponic system into the new greenhouse, integrating them with the client's existing Priva environmental control infrastructure. Universal sensors, rainwater harvesting, and sustainable biomass energy integration completed the full system scope — delivered as a single integrated project.
What crops can be added to an existing salad operation through hydroponic conversion?
Hydroponic systems open crop portfolio options not viable in soil-based greenhouse production. For the leading UK salad grower, the conversion enabled basil and parsley production alongside the core lettuce and Pak Choi operation. Basil achieved 2.6kg/m² per cut across multiple annual cycles — an entirely new profitable revenue stream. The ability to extend into herbs significantly diversified the client's market position and reduced dependence on the core salad crop categories.
