Integrated Greenhouse, Water & Fertigation Project
One brief for a project where the growing envelope, the water chain and the nutrient delivery equipment have to work as one system — and one procurement package map so each part is still quoted by the supplier that actually builds it.
How should an integrated greenhouse, water and fertigation project be procured?
Plan it as one technical baseline and buy it as separate packages: greenhouse envelope, civil works, water source and storage, pumping and filtration, water treatment, irrigation zones, fertigation equipment, drain collection and disinfection, climate control, automation, electrical, energy, post-harvest, installation and commissioning. The value is in making the interfaces between those packages explicit before quotations are requested.
- Fertigation equipment is capital; fertilizer product is bought separately
- Six interface risks decide most integrated project overruns
- SeedMatchGroup coordinates procurement, not engineering
- No supplier is approached before manual review and internal approval
Where integrated projects actually fail
Each row is a boundary between two suppliers. State in the brief who owns it.
| Package | Meets | Interface risk |
|---|---|---|
| Water quality | Fertilizer solubility | Hardness, bicarbonate and sodium in the source water decide which fertilizer forms can be used at all. Whoever specifies the dosing unit is rarely the party that analysed the water. |
| Irrigation flow | Dosing capacity | Peak simultaneous zone flow must sit inside the injection capacity and channel count of the fertigation head. An oversized irrigation design quietly disables the fertigation specification. |
| Fertigation controller | Climate computer | Two control systems from two suppliers, one irrigation strategy. State which system owns the schedule, which owns the sensors, and who integrates them. |
| Drain recirculation | Disinfection | Recirculation without a sized disinfection step transfers root pathogens across the whole crop. The two are usually quoted by different packages. |
| Main equipment | Local civil and electrical works | Foundations, trenching, supply connection and standby power are almost always local scope. Gaps here appear as delay, not as a line in the quotation. |
| Greenhouse climate design | Crop assumptions | A climate specification is written against an assumed crop, cycle and target market. If those change, the envelope is wrong regardless of supplier quality. |

FAQ
One capital project where the greenhouse envelope, water source, irrigation, fertigation equipment, drain handling, climate control, energy and post-harvest are planned together rather than bought one at a time. It is still quoted as separate procurement packages, because different suppliers build different parts.
No. Fertigation is the delivery equipment and belongs to the capital project; fertilizer is a recurring product bought on different commercial terms and is always requested separately.
A single vague mega-RFQ produces offers that cannot be compared and hides the interfaces where projects actually fail. Separate packages against one shared technical baseline keep the offers comparable and make responsibility boundaries explicit.
No. SeedMatchGroup is not an engineering company, EPC contractor or agronomy consultancy. It structures the requirement and coordinates the procurement process; final design, sizing and performance are the responsibility of the appointed suppliers or your own engineer.
Nothing is sent to any supplier. A sourcing specialist reviews the brief manually, may return clarifying questions, and supplier outreach only begins after internal approval.
