Smart greenhouse specification: control system, sensors, data and commissioning
Sources reviewed: · SeedMatch Group editorial team
Short answer
A smart greenhouse specification should list what is measured, what the controller switches, how the control logic and manual overrides work, who can access and export the data, how remote access is secured and which tests prove it all works before handover. “Smart” or “IoT-enabled” on its own is not a specification; measurable functions and acceptance tests are.
What “smart” should mean in a purchase specification
SeedMatch analysis
Suppliers use “smart greenhouse” for anything from a few wireless sensors feeding a phone app to a full climate computer running vents, screens, heating, cooling, CO2 dosing and fertigation across several zones. Offers built on the same label can therefore differ completely in scope.
A useful specification describes functions rather than labels: the variables measured and where, the equipment the controller drives, how setpoints change through the day and season, what happens when a sensor or the internet connection fails, and how the grower gets the data out. Everything else follows from the crop, climate and labour plan of the project.
What controlled trials show, and what they do not
Wageningen University & Research has run the Autonomous Greenhouse Challenge since 2018. Teams have grown cucumbers, cherry tomatoes, lettuce and dwarf tomatoes with remote, AI-based control, and the organisers report that higher yields, lower water and energy use and better crop quality were achieved in the challenge compartments. The first edition, published in 2019, compared AI-controlled compartments with a manually operated reference and found that AI performed well overall, with one team outperforming the reference.
These are results from research compartments with expert teams and dense sensing. They show what well-designed control can do; they are not a yield or savings promise for a commercial site, whose result depends on crop, climate, structure, water, management and maintenance.

The specification in one table
SeedMatch analysis
The fields below are a starting point. Values are set by the buyer and confirmed in each supplier's offer; none are SeedMatch defaults.
| Layer | What to state in the request | How to verify before handover |
|---|---|---|
| Structure | Design basis for wind, snow and crop loads at the site, covering material and the design standard used (in Europe, EN 13031-1 for commercial production greenhouses). | Structural calculations and drawings signed by the responsible engineer. |
| Sensors | Variables (air temperature, humidity, radiation, CO2, substrate moisture and EC, drain volume and EC), number and location per zone, calibration certificate and recalibration interval. | Cross-check of each sensor against a reference instrument on site. |
| Climate control | Equipment the controller drives (vents, screens, fans, cooling, heating, CO2), number of climate zones, setpoint logic and manual override at each actuator. | Function test of every actuator from the controller and by manual override. |
| Fertigation | Dosing method, target EC and pH control, number of nutrient recipes, drain measurement and alarm thresholds. | Dosing test against a calibrated EC and pH meter; alarm test. |
| Failure behaviour | Safe positions on power, sensor or network failure, backup power, local operation without internet, alarm channels. | Simulated power and network failure with alarms received. |
| Data and software | Data export format and frequency, open interface or API, data ownership and retention, licence and subscription terms. | Export of a test dataset in the agreed format. |
| Cybersecurity | User accounts and roles, how remote access is secured, update policy and support period for software and firmware. | Remote-access configuration and update procedure documented. |
| Support | Training, spare parts list, service response time, documentation language. | Training delivered; as-built documentation and spare parts handed over. |
Data access and cybersecurity rules to check
In the European Union, the Data Act has applied since 12 September 2025. It gives users of connected products rights to access and share the data generated by their use, which is relevant when a greenhouse controller or sensor platform stores data in the supplier's cloud.
The Cyber Resilience Act sets cybersecurity requirements for products with digital elements. Its reporting obligations for manufacturers apply from 11 September 2026 and its main requirements from 11 December 2027. Outside the EU these laws may not apply, but the same questions belong in the request: who holds the data, how it can be exported, how remote access is protected and for how long security updates are provided.
For industrial control systems, the ISA/IEC 62443 series is the widely used reference for security practices; a supplier can state which parts of it, if any, its products or processes follow.

Commissioning and acceptance tests
SeedMatch analysis
Most disputes about smart greenhouses arise after installation, when nobody agreed in advance what “working” means. Writing the acceptance tests into the request avoids this.
- Sensor check: every sensor read against a reference instrument, with results recorded.
- Actuator check: every vent, screen, fan, pump and valve operated from the controller and by manual override.
- Alarm and failure check: simulated power, sensor and network failure, with alarms reaching the named people.
- Data check: a test export in the agreed format, and confirmation of who holds the account credentials.
- Handover: training, as-built drawings, settings backup and the spare parts list; many buyers link part of the payment to signed acceptance.
From specification to request
SeedMatch analysis
The greenhouse request form captures site, crop, area, climate, structure and control requirements. A complete specification lets the team compare offers on the same basis. SeedMatch does not publish prices or availability, and every offer must be confirmed in writing by the supplier.
Frequently asked questions
What should a smart greenhouse specification include?
The variables measured and where, the equipment the controller drives, setpoint logic and manual overrides, behaviour on power or network failure, data export and ownership, remote-access security, training and the acceptance tests that prove each function works.
Does a smart greenhouse guarantee higher yields?
No. Research such as the Wageningen Autonomous Greenhouse Challenge shows that well-designed control can raise yields and cut water and energy use in trial compartments, but commercial results depend on crop, climate, structure, water, management and maintenance.
Who owns the climate and fertigation data?
Whatever the contract says, so state it in the request. In the EU, the Data Act has applied since 12 September 2025 and gives users of connected products rights to access and share the data their use generates.
Which standard covers greenhouse structures?
In Europe, EN 13031-1:2019 sets principles and requirements for the design and construction of commercial production greenhouses. Other markets apply their own building codes, so ask the supplier to name the design basis used for your site.
Does SeedMatch sell greenhouses or quote prices?
No. SeedMatch Group coordinates buyer requests through a human-reviewed process; it does not manufacture or install greenhouses and does not publish prices. Buyers use the service free and supplier contact is mediated.
Ready to send a smart greenhouse specification?
Use the greenhouse request to send site, crop, area, structure and control requirements. A specialist reviews each request before any supplier is approached. Commercial projects start at USD 250,000.
