Compare greenhouse production strategies
Compare the business case—not just €/m².
A coherent greenhouse comparison binds each technology level to its own marketable yield, season, plant count, labour, water, losses, market timing and risk.
The comparison rule
Never combine tunnel CAPEX with high-tech performance.
A low structure price does not automatically create a low cost per kilogram. Equally, a professional greenhouse does not automatically deliver a high yield. Crop performance depends on the greenhouse, location, variety, planting date, climate strategy, water and nutrition, crop protection, workforce, technical reliability and management discipline working together.
The illustration below compares three FlowGrow routes against a common annual tomato production target. It is a decision example, not a quotation or yield promise. Its purpose is to show why area, technology and required marketable yield must move together. Before commercial use, every assumption must be replaced or confirmed for the actual geography, crop cycle, supply scope and market.
- Marketable production
- Use saleable kilograms after plant losses, rejected product and pack-out—not theoretical biological output.
- Revenue timing
- Calculate weekly harvest against the applicable weekly selling price and buyer requirements.
- Total operating system
- Include plants, labour, water, fertilizer, crop protection, energy, maintenance, packing and logistics.
- Downside case
- Test delayed planting, lower yield, weaker prices, crop loss, technical downtime and management gaps.
Annual production ≠ annual revenue
Two greenhouses producing the same annual kilograms may not create the same sales. Earlier or later harvests, consistency, grade, pack-out and access to a stronger market window can change the average realized price. Revenue should therefore be modelled as weekly marketable kilograms multiplied by the relevant weekly price.
Risk is transferred, not eliminated
Separated tunnels can distribute damage, disease and restart risk across units, but use more land, plants and routine crop work for the same output target. A connected multi-span greenhouse concentrates control and professional performance in a smaller footprint, while a crop, irrigation or management failure can affect a larger share of production at once.
OPEX depends on local reality
More plants can increase plant material, irrigation, fertilizer, crop-protection exposure and crop-work volume. Higher technology can reduce land and routine labour but increase energy, maintenance and specialist-management requirements. Local wages, energy prices, water quality and operating strategy decide the result.
What the final feasibility model must show
Compare total and per-kilogram economics.
The final project model should connect investment and working capital to a monthly crop and sales curve. It should show normal, adverse and strong-season scenarios and make the effect of yield, price, timing and loss visible. No desired return may be created by silently increasing yield, selling price or terminal value.
- Land and plants
- Area, density, total plant count, plant-material cost and expansion capacity.
- Water and inputs
- Source, treatment, storage, fertilizer, crop protection, drainage and recirculation assumptions.
- People and systems
- Headcount, skill profile, management, climate control, maintenance and technical dependency.
- Commercial result
- Weekly sales, OPEX, working capital, operating cashflow and sensitivity without guarantees.
