Short answer: Before shipment, buyers should receive a written warranty scope, recommended spare-parts list, manuals, electrical drawings and commissioning checklist. Warranty does not replace spare parts, routine maintenance or trained operation. Each system should have a clear acceptance test and responsibility boundary.
A greenhouse combines structure, covering, motors, pumps, controls, irrigation and crop equipment. These items may come from different manufacturers and have different service conditions. A single statement such as one-year warranty can be misleading unless it identifies the covered components, start date, exclusions and claim process.
| System | Questions to record |
|---|---|
| Steel structure | What defects are covered, and which corrosion or misuse conditions are excluded? |
| Covering | Is the warranty from the material manufacturer, and what installation conditions apply? |
| Motors and drives | Which motor, gearbox, limit switch and moving parts are included? |
| Climate controls | How are sensors, controller hardware, software settings and electrical damage handled? |
| Irrigation and fertigation | Which pumps, valves, filters and dosing components are covered? |
| Hydroponic equipment | Which channels, tanks, pumps, fittings and controllers have separate conditions? |
The first spare-parts package should reflect the installed equipment and local availability. Typical categories include fasteners, film-fixing parts, vent-drive parts, limit switches, contactors, fuses, relays, solenoid valves, pump seals, filters, irrigation connectors, drippers, sensors and repair materials. The exact list depends on the final bill of materials.
High-value components do not always need a complete spare unit. Ask the supplier which parts are common failure points, which items have a long delivery time and which replacements require factory configuration.

Commissioning and operator-training checklist
Commissioning should test the greenhouse as connected systems rather than isolated products. Check doors, vents, screens, motors, limit switches, fans, cooling-pad pumps, alarms, sensors, irrigation pressure, filter flushing, fertigation dosing and emergency operation. Record test results, controller settings and unresolved items.
Use dated photos, videos, test sheets and signed checklists. Record serial numbers for motors, controllers and pumps where available. Acceptance evidence helps distinguish transport damage, installation error, setup problems and product defects. It also gives the farm team a baseline for future maintenance.
Provide the project name, component identification, serial number if available, installation date, fault description, photos or video, controller messages and troubleshooting already completed. Do not continue operating a damaged mechanism when it may create a larger failure. Ask whether the supplier needs the failed part returned or inspected.
Routine tightening, lubrication, film inspection, gutter cleaning, filter flushing, sensor calibration and electrical checks reduce failures. Local operators should know manual override and emergency shutdown procedures. Keep critical spare parts dry, labeled and connected to the final parts list.
Often it does not. Consumables and wear parts should be identified separately in the warranty matrix and spare-parts list.
The contract should state whether it starts from shipment, arrival, installation or commissioning. Do not leave the start point undefined.
Prioritize parts matched to the installed bill of materials, items with long delivery times and components that can stop ventilation, irrigation or climate control.
Test structure interfaces, vents, drives, controls, sensors, fans, pumps, irrigation, alarms, emergency operation and operator understanding.
