How to choose a commercial greenhouse supplier
Choose a commercial greenhouse supplier on nine criteria: experience with your crop, experience in your climate, projects at your scale, in-house engineering depth, installation and commissioning capability, agronomy support, local service and spare-parts presence, warranty terms per component group, and lifecycle cost rather than headline CAPEX. Reference projects in the same climate and crop are the strongest single indicator.
Supplier selection is a scoring exercise, not an impression. The criteria below can be applied to any bidder, and each one is verifiable by asking a direct question and requesting evidence.
The nine evaluation criteria
- Crop experience — reference projects growing your crop commercially, not a brochure mention
- Climate experience — projects in comparable radiation, temperature, humidity and load conditions
- Scale fit — projects at your hectarage; a supplier strong at 0.5 ha may not suit 10 ha, and vice versa
- Engineering depth — who performs structural calculation, and to which standard
- Installation and commissioning — own crews, subcontractors, supervision model and site safety record
- Agronomy support — is start-up support included, optional or absent
- Local service — presence, response time, language and spare-parts logistics
- Warranty — duration per component group and what voids it
- Lifecycle cost — energy behaviour, replacement intervals and maintenance demand
Questions that separate bidders quickly
- Which design standard did you apply for wind and snow, and what values did you use for this site?
- What is the usable growing area of the layout you have priced?
- Which parts of the installation are performed by your own crew?
- Who is responsible if the climate equipment and the fertigation controller do not integrate?
- What is your service response time to this country, and through whom?
- Which three references can I contact that grow this crop in a comparable climate?
How to score fairly
Keep technical compliance and commercial terms in separate columns. Clarify or exclude technically non-compliant bids before price is considered, otherwise the cheapest incomplete offer distorts the whole evaluation.
