Standardized where it matters
The structural rhythm, steel basis and polyethylene envelope remain consistent. That gives growers, installers and project partners a clear unit for site planning, logistics, quality control and phased investment.

Fixed geometry · repeatable quality
One commercial tunnel, repeated with confidence.
The FlowGrow Tunnel is not redesigned into a different greenhouse for every order. Its 9.60 × 32.50 m geometry, high-quality steel and high-grade polyethylene covering form a consistent 312 m² production unit. Crop, climate and water systems are then selected around that proven, repeatable basis.
A complete production package
The tunnel can be combined with water storage, filtration, irrigation, fertigation and crop-support systems. Optional low-pressure misting and individual suspended heaters extend the operating toolkit where the crop and seasonal climate justify them.
Built for practical deployment
Prepared components, repeatable connections and a structured installation sequence reduce on-site improvisation. Local teams can assemble the kit with appropriate training and supervision while DutchAgriTech retains a consistent technical basis.
Scale without changing the system
A project can start with one unit, move through the standard 3, 6 and 12-unit layouts, or combine larger clusters. Expansion adds known 312 m² modules instead of introducing a new greenhouse type at every step.
A phased expansion routeExplore 1, 3, 6 or 12 units above. Each step has an exact covered area: 312, 936, 1,872 or 3,744 m².
Climate options without vague regional claimsSuitability is assessed from actual site conditions. Natural ventilation is the basis, with optional low-pressure misting and suspended heaters where required.
Standardized. Commercially established. Ready to scale.
FlowGrow Production Cluster
Build a food-production system from known 312 m² units.
A cluster combines standardized tunnels with shared water, crop, service and logistics infrastructure. The greenhouse remains repeatable while the surrounding production system is sized for the project.
- 12-unit cluster
- 3,744 m² covered area
- 24-unit example
- 7,488 m² covered area
- Shared systems
- Water, fertigation, service, packing and cold storage as required
- Deployment model
- Commercial farms, institutions and structured grower programs
Institutional application
Repeatable units make programs easier to specify, train and expand.
Food-production programs can deploy the same physical greenhouse across multiple growers or sites while organizing shared procurement, installation, water infrastructure, agronomy, training and market access. The result is a scalable operating concept—not a collection of unrelated tunnel designs.

Before a price is valid
Country, site, structural loads, crop, production objective, utilities, local works, installation scope, currency basis, exclusions and validity must be confirmed.
Where this model fits
The FlowGrow Tunnel is the most accessible route for modular protected cultivation where simple operation, phased investment and physical compartmentalization matter more than maximum environmental control. It can suit a first commercial step, a distributed grower program or a farm that wants to add production in manageable units.
How it must be operated
Tunnel performance depends on disciplined basic horticulture: reliable water, uniform irrigation, ventilation management, crop hygiene, frequent scouting and timely harvest. Repeating small structures increases the number of beds, plants, irrigation lines and crop-work routes that must be managed. The operating plan must therefore test total labour, water, plant material and crop-protection exposure—not only the low structure cost.
Risk and resilience
Separated tunnels can limit the physical reach of storm damage, disease or an irrigation problem, but simpler climate protection gives less control over heat, humidity, season length and market timing. The model is strongest when the operator understands that distributed robustness and lower technical dependency are purchased with more area and more routine crop work.
Project facts to verify
The model name is not yet the specification.
Site, crop, market and operating evidence determine the final configuration. These questions must be answered before engineering and budget direction become reliable.
- Wind, rainfall, heat and ventilation requirement
- Water quantity, quality, storage and filtration
- Plant count, labour route and hygiene between tunnels
- Market window and realistic protected-crop performance
Commercial qualification
Transparent direction before a formal quotation.
We will not publish fabricated package prices. Budget guidance becomes meaningful only when its basis, scope and validity are explicit.
- Indicative supply range
- Quotation after location, unit count, crop and selected systems are qualified
- Indicative complete-project range
- Complete-project range requires water, utilities, logistics, installation and local-works inputs
- Lead-time basis
- Confirmed after engineering scope, production slot, logistics route and local readiness review
- Local works assumption
- Foundations, utilities, roads, drainage and local labour are defined per site and quotation

Tunnel greenhouse questions
Direct answers for early project decisions.
What is the standard FlowGrow Tunnel size?
Every standard greenhouse is 9.60 × 32.50 metres, providing exactly 312 m² of covered production area. The geometry, high-quality steel and high-grade polyethylene covering remain consistent between projects.
How can a FlowGrow Tunnel project expand?
Standard configurations contain 1, 3, 6 or 12 tunnels. Larger projects combine the same repeatable units into clusters; 24 tunnels, for example, provide 7,488 m² of covered production area.
Which crops can be grown in a tunnel greenhouse?
Potential crops include tomatoes, peppers, cucumbers, strawberries and leafy greens. The appropriate crop depends on climate, market window, water quality, labour and the achievable growing environment.
Is a tunnel greenhouse suitable for a hot climate?
It can be suitable in warm, dry, Mediterranean, subtropical and seasonally dry locations when orientation, ventilation, film, insect netting, shade and water strategy are assessed together. Optional low-pressure misting is available; suspended heaters can support colder periods.
How much does a commercial tunnel greenhouse cost?
A valid quotation depends on location, structural loads, unit count, crop systems, water infrastructure, logistics, installation and local works. The former generic price-per-square-metre indication is therefore not used.
When should a grower move to Multi-Span or AeroVenlo?
Move from separate Tunnel units to a connected Multi-Span when centralized production space and climate functions become important. AeroVenlo is the next professional step when full Venlo geometry, greater growing volume and double continuous roof ventilation are required.
