Hydroponic Multi Span Greenhouse Cuts Water Use for European Leafy Green Producer

As European consumers demand fresh, pesticide-free leafy greens all year, producers are turning to soil-free cultivation. One leafy green grower wanted to combine the climate control of a modern greenhouse with the resource efficiency of hydroponics. The result was a hydroponic multi span greenhouse engineered by Xiamen Wellgain Greenhouse Engineering Co., Ltd..

The project set out to prove that a commercial greenhouse can be both highly productive and genuinely sustainable when the structure and the growing system are designed together.

Client Background and Challenge

The client grows lettuce and mixed salad greens for retailers that require a steady, high-quality supply. Their goals were clear:

• Reduce water and nutrient consumption
• Produce clean, consistent leafy greens without soil-borne disease
• Maintain productivity through colder months
• Use every square meter of the greenhouse efficiently

Solution: Multi Span Structure with Hydroponic Growing

We supplied a multi span film greenhouse integrated with an NFT hydroponic growing system. The steel frame and film covering create a stable micro-climate, while sloped PVC growing channels deliver a continuous nutrient film to the roots — maximizing water and nutrient use and speeding up growth cycles.

Project Configuration

Results and Benefits

• Significant water savings – recirculating nutrient solution reduced water use compared with soil growing.
• Faster, cleaner harvests – crops matured quickly and uniformly with no soil-borne disease pressure.
• Higher output per square meter – multi-layer channel layouts maximized usable growing area.
• Steady supply – the greenhouse micro-climate kept production reliable across seasons.

Delivery and Support

Xiamen Wellgain Greenhouse Engineering Co., Ltd. supported the client throughout, from greenhouse sizing and channel layout to system documentation and export logistics. Because the structure and the growing system were specified together, the client avoided the compatibility problems that often arise when a greenhouse and its equipment are sourced separately.

Looking Ahead

The modular nature of the multi span frame means the grower can expand capacity in stages as retail demand grows, adding bays and channel runs without disrupting existing production. This scalability was a decisive factor in choosing a Wellgain greenhouse over a fixed custom structure.

Why the Project Worked

Pairing a strong structural envelope with an efficient growing method gave the client the best of both worlds: a protected, controllable environment and dramatically lower resource consumption. Xiamen Wellgain Greenhouse Engineering Co., Ltd. advised on channel profiles, layout and system sizing from the early planning stage.
