Short answer: A tropical NFT lettuce greenhouse should be planned as one complete production system. The greenhouse structure, shading, ventilation, cooling, NFT channels, nutrient circulation, seedling area and shipping plan must be matched to the local climate and target plant capacity.
NFT lettuce production depends on stable water flow, nutrient control and root-zone temperature. In a tropical region, high solar radiation, warm nights, humidity and unstable electricity can affect crop quality and system reliability. Buying channels and a greenhouse separately may create mismatched dimensions, insufficient cooling or difficult maintenance. A coordinated layout reduces these risks and gives the buyer a clearer equipment list for quotation comparison.
| Part | What buyers should confirm |
|---|---|
| Greenhouse | Steel specification, span and bay dimensions, covering material, ventilation openings, insect net and design climate. |
| Cooling and shading | Shade rate, exhaust-fan capacity, cooling-pad area, water circulation and control method. |
| NFT system | Channel material, channel dimensions, planting distance, support frame, slope and return-water design. |
| Nutrient system | Tanks, pumps, filters, A/B dosing, EC and pH management, valves and spare parts. |
| Operation area | Seedling section, service aisles, transplanting route, harvest handling and packing space. |
A buyer should first separate total greenhouse area from usable NFT growing area. Columns, service aisles, seedling space, nutrient tanks and work areas reduce the area available for channels. The number of plant positions therefore changes with the selected planting distance and workflow. Ask the supplier for a dimensioned channel layout rather than accepting a plant-count estimate based only on square meters.
This information helps determine whether natural ventilation, shading and circulation fans are sufficient or whether a cooling-pad and exhaust-fan system should be included.
There is no responsible fixed price for a complete NFT greenhouse without a confirmed layout and climate design. Compare quotations by supply boundary: steel quantity and coating, film specification, ventilation, cooling equipment, NFT channel quantity, pump duty, filtration, nutrient dosing, controls, spare parts, packing and installation support. A lower total price may exclude components needed for reliable operation.
Container quantity depends on the final steel structure, channel length, cooling equipment, tanks and packing method. The supplier should first freeze the bill of materials and then provide packing dimensions, gross weight and container estimate. Buyers requesting CIF pricing should provide the destination port and confirm whether local customs clearance, inland delivery and installation are excluded or included.
It may be possible, but capacity must be verified with a layout based on greenhouse dimensions, channel spacing, aisles, seedling area and operating workflow.
Plastic film is commonly considered for cost-sensitive projects, but the final covering and ventilation design should match wind, rainfall, temperature and replacement planning.
The quotation should state the greenhouse structure, covering, climate systems, NFT equipment, nutrient system, controls, drawings, spare parts, packing, trade term and installation-support boundary.
Quotation terms can be prepared after the destination port, configuration and packing plan are confirmed. The inclusions and exclusions of each trade term should be listed clearly.
