Greenhouse project planning in Vietnam — crop, climate, size and water before suppliers
Projects in Vietnam are usually shaped by humidity, disease pressure and structural loading. Ventilation and crop protection decide whether production is stable, while wind, rain and in some areas typhoon loading decide what the structure must withstand.
Short answer
Before contacting greenhouse suppliers for a project in Vietnam, define the crop and buyer, the measured climate at the exact site, the annual production target and growing area, the water source, volume and analysis, the available energy, and the technology level the market justifies. Asia-Pacific projects are typically decided by humid tropical and temperate conditions, so write those conditions into the request rather than leaving each supplier to assume them. With one specification, quotations become comparable.
What usually decides the specification in Vietnam
Humidity and disease management
High humidity limits transpiration and raises disease pressure. Vent area, air movement, screens and, where justified, dehumidification should be specified against the crop's requirements.
Structural loading
Wind speed, rainfall intensity and, in exposed regions, typhoon risk drive the structure class, anchoring and drainage. Quote requests should state the design wind speed.
Rainwater handling and harvesting
Roof drainage capacity is a design item, and harvested rainwater is often the cleanest source available for fertigation.
Crop protection and insect exclusion
Netting grade affects airflow and therefore the cooling strategy; the two must be chosen together.
Labour and automation balance
Automation should match the team that can realistically be recruited and trained at the site, not a demonstration facility.
Site information to confirm before quotations
- Design wind speed and rainfall intensity for the site
- Typical humidity range and crop tolerance
- Water source, volume and analysis, including rainwater capacity
- Site drainage and flood risk assessment
- Available labour and training requirement
Climate, water and energy vary widely inside Vietnam. Use measured data from the actual site rather than national averages — that single difference is what makes quotations comparable.
Climate, water, power and cost in Vietnam
These four inputs decide most of the specification and most of the budget. Treat them as the starting point of the request for quotation, and confirm each one with measured site data before suppliers are approached.
Climate
Northern sites have a cool season while southern sites are hot and humid year-round; typhoon exposure affects coastal structures.
Water
Surface and groundwater are used; salinity intrusion in delta areas and analysis must be checked before design.
Power and energy
Grid coverage is broad but backup for cold rooms and dosing is advisable.
What moves the cost
Wind-rated structure, humidity control, water treatment in delta areas and cold chain drive the budget.
For a budgetary range per square metre based on these inputs, use the greenhouse quote calculator. It produces a planning estimate, not a quotation.
Common reasons quotations get re-issued
- Design wind speed not stated, so structures are not comparable
- Insect netting reducing airflow below the cooling requirement
- Roof drainage and site flooding not assessed
- Humidity control omitted for a crop that needs it
- Automation level exceeding available skilled labour
