London Primary School:
Growing System for School Catering and Curriculum
A growing system for a primary school serves two objectives simultaneously: reliable fresh food production for a daily catering operation, and a living educational resource that connects students directly to where their food comes from. Designing for both requires a different approach than either objective alone.
Saturn Bioponics, working with a specialist education sector partner, designed and installed a polytunnel-based hydroponic growing system for a London primary school with approximately 400 students. The system supplies fresh salads and vegetables to daily lunchtime catering throughout the academic year, with curriculum integration across science, nutrition, and sustainability supporting active student engagement in growing and harvesting activities.

The Challenge: Designing for Catering, Curriculum, and Community Simultaneously
The London primary school had a clear set of objectives: grow fresh produce on site, supply it consistently to the school catering operation, and use the growing system as an active part of the curriculum. These objectives pull in slightly different directions. A pure catering installation would prioritise yield, operational simplicity, and year-round consistency. A pure educational installation might prioritise accessibility and visual engagement over production throughput. A system that serves both well requires those requirements to be held in balance from the design stage.
School growing systems also operate within a specific environment: one where the staff running the system are primarily teachers and catering personnel rather than specialist growers, where the production function must fit around the rhythms of the academic year, and where the system design must be appropriate for the school community it serves. Adapting a commercial growing system for this context requires genuine design consideration — not just a scaled-down version of something designed for a different purpose.
Saturn Bioponics worked with a specialist education sector partner who brought detailed knowledge of school procurement, regulatory requirements, and curriculum integration. Together, the partnership delivered a system that met all three objectives — fresh food for catering, active educational resource, and a source of community ownership and engagement for the wider school.

The System: Polytunnel Hydroponics for Catering and Curriculum
A polytunnel-based hydroponic facility within the school grounds provided the year-round production environment the catering function required, while also creating a defined, managed growing space that could be used as an active educational setting throughout the academic year.
Polytunnel Infrastructure — Year-Round Production
The polytunnel structure enabled consistent fresh produce supply across all terms — including the autumn and winter months when outdoor growing would not be viable. Year-round availability is the operational requirement for a catering function; a system that produces only in summer terms does not support daily meal preparation throughout the academic year. The polytunnel also provided the defined physical space required for managing student engagement in growing activities — a clear boundary between the general school grounds and the growing environment.
Hydroponic Growing Systems — Fresh Salad and Vegetable Production
The hydroponic growing systems were specified for the crop portfolio required by the school catering operation: fresh salads and a range of vegetables suited to integration into daily lunchtime meal preparation. Crop selection balanced catering requirements — varieties that perform reliably in a polytunnel hydroponic environment and integrate smoothly into kitchen operations — with educational interest, ensuring students could engage meaningfully with recognisable, familiar crops throughout the growing cycle.
Curriculum Integration — Growing as a Teaching Resource
The educational access layout was designed alongside the production system. Student engagement zones allowed involvement in growing and harvesting activities as part of the curriculum. The system supported science teaching through plant biology and growth cycles; nutrition education through the direct connection between growing, cooking, and eating; and sustainability education through water efficiency, reduced food miles, and closed-loop thinking. Teaching staff were briefed on how to use the growing system as a teaching resource, with the operational layout designed to support classroom-to-growing-area educational activities throughout the academic year.
Operational Design — School Staff Operation
The system was designed from the outset to be maintained by school staff — catering personnel and teaching staff — without requiring specialist growing expertise. Operational simplicity was a core design requirement: clear, straightforward procedures for routine maintenance, irrigation management, and crop harvesting, documented in a format suitable for handover between staff members across academic years. The education partner provided the school-specific operational integration, procurement navigation, and ongoing support framework appropriate to the school environment.

Outcomes: Fresh Food, Active Curriculum, and Community Ownership
Fresh salads and vegetables produced on site are integrated into daily lunchtime meal preparation, improving the quality and freshness of catering produce while reducing procurement costs. The catering team has a consistent, local supply of produce that students have had a direct hand in growing — a connection that changes how the food is perceived and received at mealtimes.
Student involvement in harvesting activities and growing education has created genuine engagement with food production — one of the most effective ways to build understanding of nutrition, sustainability, and where food comes from. The school-wide involvement in producing food for their own meals generates a sense of community ownership and pride that standard catering provision simply cannot create. For a primary school, the growing system is not just a food production facility. It is part of what the school is.

What This Project Demonstrates for Schools
The London primary school project sits within Saturn Bioponics' broader educational portfolio — alongside university research facilities at Birmingham and Warwick, agricultural colleges at Pershore and CAFRE, and international academic partnerships. The school project represents a different application of the same underlying capability: designing growing systems for the specific objectives and operating environment of the institution, rather than adapting a general-purpose commercial system.
For schools considering a growing system, the decision involves more than the growing technology. It involves how the system will be used day-to-day by people whose primary role is education and catering, not horticulture. Saturn Bioponics designs with that reality in mind — and the education sector partnership model means there is specialist support for the school environment aspects of the project that sit outside Saturn's core growing system expertise.
Frequently Asked Questions
Questions from school business managers, head teachers, catering teams, and education sector partners considering school growing systems.
What does a hydroponic growing system designed for a primary school look like?
A primary school growing system is designed around the specific requirements of the school environment — the catering objectives, curriculum integration aims, available space, and operational capabilities of the staff who will run it. At the London primary school, this meant a polytunnel-based hydroponic facility producing fresh salads and vegetables for daily lunchtime catering, with an access and operational layout supporting student engagement in growing and harvesting activities as part of the curriculum. The system was specified to be maintained by school staff without specialist growing expertise, with operational simplicity built into the design from the outset.
Can a school growing system supply a meaningful proportion of fresh produce for daily catering?
Yes — and the London primary school project demonstrates this directly. The polytunnel-based system supplied fresh salads and vegetables to daily lunchtime meal provision for approximately 400 students throughout the academic year. Year-round production through the polytunnel environment enabled consistent supply across all terms. The catering integration reduced procurement costs for fresh produce while improving quality and freshness. Consistency of supply is the operational requirement for a catering function, and the system was designed to deliver that throughout the full academic year.
How is a school growing system integrated into the curriculum?
Effective curriculum integration requires the growing system to be designed for dual use from the outset — as a food production facility and as an educational resource. At the London primary school, the system supported science education through plant biology and growth cycles; nutrition education through direct connection between growing and eating; and sustainability education through water efficiency, food miles, and closed-loop resource use. Students were involved in appropriate harvesting activities as part of their learning programme, creating direct engagement with the food production chain.
What crops are best suited to a primary school hydroponic growing system?
Salad crops and leafy vegetables are well-suited to school growing systems: short production cycles allow students to observe the full growing process within a term; they are familiar and recognisable to children; they integrate easily into school meal preparation; and they perform reliably in a polytunnel hydroponic environment throughout the academic year. At the London primary school, fresh salads and a range of vegetables formed the core crop portfolio — providing consistent catering supply and a meaningful range of growing experiences for students across different year groups.
What space is required for a primary school growing system?
Space requirements depend on the production objective — whether the aim is a meaningful catering contribution or a primarily educational growing experience. For a system supplying fresh produce to daily catering for several hundred students, a polytunnel growing area is typically required to achieve year-round production at useful volumes. Saturn Bioponics works with schools and their education partners at briefing stage to establish what is achievable within available space before specification begins.
Does Saturn Bioponics work directly with schools, or through education sector partners?
The London primary school project was delivered through a specialist education sector partner — a company with specific expertise in school environment navigation, procurement processes, and educational integration. This partnership model combines Saturn Bioponics' technical growing system expertise with the education partner's knowledge of school administration and curriculum requirements. Saturn Bioponics is open to both direct engagement with schools and institutions, and partnership-based delivery where a specialist education partner is the preferred route.
