Procurement knowledge
Why greenhouse, irrigation, fertigation, pumping and energy belong to one project
These systems are coupled: greenhouse area and crop set water demand, water demand sets design flow, flow and head set pump duty, pump duty and climate equipment set electrical load, and electrical load sets the energy solution. Buying them as separate purchases creates capacity mismatches and unowned interfaces that surface during commissioning.
Why should greenhouse, irrigation, fertigation, pumping, climate control and energy be planned as one project?
These systems are coupled: greenhouse area and crop set water demand, water demand sets design flow, flow and head set pump duty, pump duty and climate equipment set electrical load, and electrical load sets the energy solution. Buying them as separate purchases creates capacity mismatches and unowned interfaces that surface during commissioning.
- Area and crop → peak water demand → design flow → pump duty → electrical load → energy solution.
- Interface gaps (who supplies the header, the panel, the sensor cable) are the most common source of delay.
- Sequential purchasing locks earlier decisions before later constraints are known.
- One baseline keeps all packages sized against the same numbers.
The dependency chain
Every downstream package inherits assumptions from the one before it. If the greenhouse is contracted before water demand is calculated, the irrigation package may need a pump that the electrical supply cannot support, and the energy package then has to absorb the difference at a premium.
Interfaces that need an owner
Name the responsible party for each interface in the RFQ, not during installation.
- Greenhouse structure to irrigation header and internal distribution.
- Head unit to fertigation dosing and to the climate controller.
- Pump station to electrical panel, control signals and protection.
- Energy system to the load profile of pumps, fans, screens and lighting.
- Civil works to equipment foundations, trenching and drainage.
Practical sequence
Define crop and area, calculate water demand and flow, size filtration and dosing, derive pump duty and head, total the electrical load, then package the scopes with named interfaces and issue them against one baseline.
