Ventilated film route
Consider where the market window can be served with disciplined ventilation, irrigation and crop work.
Limit: Do not assign glasshouse yield, year-round output or climate stability to a simpler cover.

Commercial Tomato Greenhouse Project Scenario
How a tomato greenhouse brief joins the buyer, climate, water, energy, labour and start-up plan before selecting a structure.
Discuss your projectScenario status
A planning example, not a delivered client case.
This scenario combines general greenhouse design and operating lessons. It is not a real DutchAgriTech installation. No client, location, area, yield, savings or sales result is claimed. Actual recommendations require a verified site, crop, buyer and project scope.
Starting situation
The commercial question comes first.
Imagine a grower seeking regular fresh-market tomato supply beyond the local open-field season. The buyer wants consistent grade and delivery by week, but the site has hot months, an uncertain water source and no confirmed energy strategy. The immediate question is not how many square metres of glass to buy. It is which crop calendar and quality standard can be supported by the location and the operating team.
The project team first agrees the tomato type, variety shortlist, grade, pack and target harvest weeks. It tests the hardest climate periods and samples source water. Only then can it compare a ventilated film greenhouse with a glasshouse offering more climate control. A higher-control design may be justified by the desired season, but only if power, energy, maintenance and crop-management capability are credible.

Professional glasshouse route
Consider where durability and additional control support the defined crop cycle and buyer specification.
Limit: Heating, screens, cooling or lighting need separate energy and operating cases.
Phased development
Reserve layout, utilities and water capacity for expansion after the first crop and team are proven.
Limit: Expansion space is useful only if the first phase has a coherent business case.
System decision
Climate and energy
Model temperature, humidity, radiation and ventilation by month. If heating, cooling, screens or supplemental light are proposed, specify their purpose, energy source, reliability and control responsibility. The best equipment list is not automatically the most profitable crop plan.
System decision
Water and root zone
A laboratory analysis and seasonal supply assessment determine treatment, storage, fertigation and drainage. Define monitoring and an emergency irrigation response before automation is selected.
System decision
Labour and post-harvest
Trellising, pruning, scouting, harvest, grading and packing create recurring labour peaks. Calculate saleable kilograms after grade-out and loss, then match weekly harvest to packing capacity and buyer collection.
Project sequence
What happens before a budget becomes useful?
The order matters: each decision narrows the next one. Keep unknowns visible rather than turning them into a precise-looking price or production claim.
- Confirm buyer specification and weekly demand.
- Collect climate, land, water and utility evidence.
- Shortlist crop cycle and greenhouse control level.
- Define supplied systems, local works and commissioning.
- Test a delayed start, lower grade-out and higher energy cost.
Evidence and downside
Test what could invalidate the plan.
If peak heat, water quality or energy cost makes the intended season impractical, shorten or move the crop window before increasing technology. If the buyer cannot confirm grade and cadence, do not convert biological yield into assumed revenue.
The useful output is a tomato production brief with two comparable scope and operating options. Area, investment and expected harvest remain provisional until the site, buyer and management inputs are checked.
