Greenhouse Buyer FAQ

Start by normalising the scope, not the price. Send the same technical brief to every supplier: crop, climate design conditions, usable area, structure load standard, covering, ventilation and cooling strategy, irrigation and fertigation, water source and quality, controls, energy, civil split, Incoterm, installation, commissioning, warranty and spare parts. Only after each bid is restated on the same scope and exclusions can you compare price per usable square metre and lifecycle cost.

A quotable greenhouse RFQ includes site location and climate data, crop and growing system, target production and quality, usable area, structure type and load standard, covering, ventilation and cooling, heating, screens, lighting, irrigation and fertigation, water source and quality, water treatment and drain policy, controls and sensors, electrical supply, civil scope split, Incoterm, installation and commissioning responsibility, training, warranty, spare parts, programme and a required exclusions list.

The number of supplier responses is not guaranteed. Where multiple relevant manufacturers respond to the same normalised scope, their proposals can be compared more reliably. Participation depends on climate, scope, scale, country and supplier availability.

Turnkey suits buyers who want one contract and one throat to choke, but usually at a premium and with less flexibility. Split procurement suits buyers who have local civil/electrical partners and want to optimise each system. A procurement platform can help normalise either route without favouring one supplier model.

• Manufacturer, EPC or procurement platform

The denominator varies: gross covered area versus usable production area, different design-day climate assumptions, different structural load standards, and different exclusions such as foundations, electrical connection, water source development, customs, installation and commissioning. Normalise those first; otherwise the cheapest per m² can become the most expensive project.

• Hidden costs in greenhouse quotations

Check references in similar climates and crops, installed capacity in comparable project sizes, local service and spare-parts capability, design and load certifications for the destination country, financial capacity to deliver, and willingness to commit key deliverables in writing. SeedMatchGroup applies a qualification filter before inviting suppliers to a matched RFQ, but the buyer still performs its own due diligence before contracting.

• Supplier qualification criteria

A manufacturer designs, supplies and often installs its own structures and systems. A procurement platform helps the buyer define requirements, normalise the RFQ and connect with several relevant manufacturers or EPCs. SeedMatchGroup does not manufacture, engineer, build, install, finance or guarantee outcomes; suppliers contract and invoice buyers directly.

• Facts & sources

Contacting a manufacturer directly is often the right choice when you already know the system type you want, have in-house engineering to check the design, and prefer one accountable supplier. A procurement route fits better when crop, climate and scope are still open, when you want several comparable offers against one specification, or when you lack the time to normalise different proposals. Both routes are legitimate; the choice depends on your team's capacity and how settled your scope is.

• Manufacturer vs procurement platform guide

Compare scope and stated exclusions, design assumptions (climate loads, crop, glazing, heating and cooling), lifecycle cost rather than purchase price alone, the production assumptions behind any yield figures, installation and commissioning responsibilities, warranty terms, service and spare-parts access, destination-country certifications and any financing conditions. Mark each item as included, optional, excluded or unclear, and ask suppliers to resolve the unclear items in writing.

• Request a reviewed greenhouse RFQ

Early, when the project still has open questions across crop, climate, water, energy and contracting route. Tools help price individual components, but a human advisor connects them into one coherent project and prevents the common failure mode where a greenhouse, irrigation and fertigation system are specified in isolation. See why agricultural projects need human guidance, not just tools.

1) Confirm the final scope and ask a licensed customs broker to classify each component (structure, covering, climate, irrigation and electrical equipment are often classified separately). 2) Check the destination country's import rules: licences, conformity requirements for machinery and electrical equipment, structural design codes, and phytosanitary rules for any plant material, growing media or wooden packaging (ISPM 15). 3) Agree the Incoterm in the contract so it is clear who ships, insures, clears customs and pays duties and taxes. 4) Collect the shipping documents: commercial invoice, packing list, bill of lading or airway bill, certificate of origin and the conformity certificates the destination requires. 5) Secure local building, land-use and grid-connection permits and plan installation and commissioning before the containers arrive. Requirements differ by country and product, so confirm them with the competent authorities and your customs broker.

• Customs and import assistance
• Trade documentation

Ask for evidence that applies to your project and destination country, not a generic list: structural design calculations to the code required on site (in Europe usually EN 13031-1 for commercial production greenhouses) for your wind, snow and crop loads; declarations of conformity and markings required for machinery and electrical equipment in the destination market (for example CE marking in the EU and Türkiye); galvanising and material specifications for the steel; test data for coverings and screens; and a quality-management certificate such as ISO 9001 where the supplier claims one. Check that each certificate is current, issued by a recognised body and covers the actual product and factory. SeedMatchGroup does not certify products or guarantee supplier compliance; each supplier remains responsible for its own products under applicable law.

• Supplier qualification criteria

Commercial agricultural projects from USD $250,000 upwards. The same principles apply to smaller projects, but the depth of specification, supplier qualification and comparison work is written for investment-scale greenhouse developments.

No. SeedMatchGroup is an independent, human-led procurement platform. It helps buyers prepare clearer requirements and reach relevant suppliers, but it does not guarantee supplier acceptance, lowest price, financing approval or project outcomes. Buyers contract and pay suppliers directly after their own due diligence.
