Greenhouse Irrigation Planner
Size daily water demand, pump capacity, storage buffer and filtration category for a commercial greenhouse or hydroponic project.
Estimate only — not a quotation. Outputs are indicative planning ranges based on the values you enter and typical commercial benchmarks. Real pricing, specifications and lead times vary by country, site conditions and supplier, and are confirmed only in written offers collected through a private RFQ.

- Primary screen / disc filter <= 130 micron on delivery line.
- Standard screen/disc filtration is sufficient; no desalination line required.
- Fertigation head with EC/pH dosing and mixing tanks.
Turn this estimate into a qualified project
SeedMatchGroup is a supplier-neutral, human-led platform. We do not manufacture or resell equipment — we help buyers specify the project, review relevant suppliers privately and compare the written offers received. Supplier participation and timing are not guaranteed.
Turn this estimate into a project brief
Send these figures to the greenhouse RFQ form. Your inputs and results are attached to the brief, a sourcing specialist reviews it, and only then are suitable suppliers or project partners approached.
Buying more than once? Save these project details to your buyer profile so your site, crop, budget and timeline are pre-filled on every future request.
Indicative only. Not financial advice, not agronomic advice, not engineering design. Final numbers require supplier, agronomist, engineer and local regulatory review.

Frequently asked questions
Typical peak daily water demand ranges 3-7 L/m2/day depending on crop, climate, VPD and irrigation strategy. Recirculating fertigation systems can cut fresh-water demand 30-50% versus drain-to-waste.
Storage buffers between water source (well, mains, harvested rainwater) and peak irrigation demand, and covers outages. Commercial greenhouses target 3-7 days of reservoir buffer plus rain-harvesting tanks if the roof allows.
Drip and fertigation require <= 130 micron primary filtration (screen or disc) and often secondary sand or membrane for surface water. Hydroponic recirculation adds UV or ozone disinfection.
Turning this estimate into a request? The irrigation and fertigation request builder lists what changes a quote — system type, filtration, dosing and drain-water scope — and opens a pre-filled request that our team reviews before any supplier is contacted.
Understanding the values
What each choice in this calculator means, and how the options differ in practice.
- Peak vs average demand
- Hydraulic design follows peak daily demand. Sizing on averages leaves the crop short exactly when stress costs the most yield.
- Efficiency assumptions
- Emitter, filtration and distribution losses compound. A few points of efficiency at each step add up to a large difference at the pump.

Illustration only, not a real project or quotation. This is the structure, equipment and site-works budget for the example greenhouse, not the price of this calculator’s individual system, seeds or inputs, and not a result calculated from your entries. Excludes land, permits, packhouse, financing costs and working capital.
Based on the published commercial greenhouse cost benchmark. Written offers require a private project review; commercial projects start from USD 250K.
What can change the result?
This is a preliminary planning estimate based on the values you entered. The variables below usually move the outcome most, and should be confirmed with an agronomist, engineer and supplier offers before final design.
- Crop and cultivar — water, climate and support requirements differ per crop
- Local climate: temperature, humidity, radiation and wind exposure
- Irrigation design, emitter spacing and application efficiency
- Water quality and treatment needs (EC, pH, iron, hardness, pathogens)
Questions this calculator answers

Method and decision path
How to use this result in a commercial project
Use the result to test scope and compare scenarios. It is not a design, agronomic prescription, financing offer or supplier quotation.
1. Enter site evidence
Replace defaults with measured area, climate, water, energy, crop and commercial assumptions.
2. Test scenarios
Change one assumption at a time and record the effect on capacity, cost, demand or return.
3. Validate the duty
Ask the relevant agronomist, engineer or financial adviser to check the inputs and constraints.
4. Prepare a private RFQ
Carry the confirmed scope into a human-reviewed brief so written offers can be compared on the same basis.
Final specifications, performance, prices, supplier participation and timing depend on the site and written supplier responses; none is guaranteed by this calculator.
Tell us five things and we route your brief
These fields decide which specialist and which suppliers see your request. Nothing is submitted here — your answers are carried into the private RFQ.
The USD 250K project threshold applies to capital projects. Recurring fertilizer programmes are reviewed by shipment size, annual volume and sourcing fit.
A sourcing specialist shortlists reviewed providers for your scope and returns comparable offers. Supplier details stay with us — all communication runs through SeedMatchGroup.
Estimate only: these figures are indicative planning numbers, not a quotation. Final pricing, specifications and lead times come from supplier offers after your brief is reviewed.

Procurement answers behind these numbers
A model output only holds if the scope, contract route and delivery terms match the assumptions. These reference answers cover the commercial decisions that move the figure.
- Turnkey EPC vs separate equipment packages
- What belongs in a greenhouse equipment specification
- Normal payment milestones in equipment contracts
- Which Incoterms to use for greenhouse and irrigation equipment
- How long a commercial greenhouse takes from order to handover
- What is normally the owner's scope on a greenhouse project
Move greenhouse irrigation planner into a structured RFQ
Editorial · not a sales pitchCalculator outputs are indicative. When your numbers stabilise, a supplier-neutral RFQ turns those estimates into a consistent brief for comparing the written offers that participating suppliers provide.
The facts a complete, supplier-neutral request on this topic includes. Use it as a checklist before submitting.
- Irrigated area, block layout and topography/elevation change
- Crop, spacing and peak daily water requirement (mm/day or m³/day)
- Water source (borehole, canal, reservoir, municipal) with yield and analysis
- System type: drip, sprinkler, pivot, micro-sprinkler, fertigation
- Required flow (m³/h), pressure and number of zones/shifts
- Power availability: grid, generator or solar pumping
- Automation and control level required
- Water analysis report and borehole test results
- Field/plot map with dimensions and elevation

Supplier and project partner outreach is handled only after a commercial project brief is reviewed.
Supplier and manufacturer content is provided for research, transparency and discovery only. Buyers submit one project or RFQ to SeedMatch Group; our team validates and organises it, manages any suitable supplier or manufacturer outreach, and presents the responses through SeedMatch. There is no public directory of company identities, automatic matching, direct messaging or direct buyer-supplier contact.
