A restaurant owner in Barcelona, Spain, who focuses on fresh ingredients and modern cuisine, has long wanted to achieve self-sufficiency in herbs and salad greens. This approach not only ensures maximum freshness from harvest to plate, enhancing flavor and presentation, but also helps reduce long-term ingredient sourcing costs. Before this project, however, he had little to no experience with hydroponic growing systems.
Because the restaurant is located in the city center with very limited backyard and rooftop space, and with clear requirements for clean, food-safe cultivation, we recommended the 6P9 hydroponic tower growing system. This vertical hydroponic system features a compact footprint while offering 54 planting sites, significantly increasing growing density in small urban spaces. It is well suited for rooftop hydroponic farming or small backyard installations. The hydroponic tower supports multi-crop cultivation, allowing the restaurant to grow basil, mint, coriander, arugula, mixed lettuce, and other high-frequency culinary herbs and leafy greens commonly used in daily kitchen operations.
The soilless hydroponic growing method eliminates soil-related pests and diseases at the source, creating a cleaner and more controlled growing environment. With precise nutrient solution management, stable EC control, and efficient water circulation, this indoor and outdoor hydroponic system ensures consistent crop quality while using less water than traditional soil farming. For the restaurant kitchen, this means chefs can harvest fresh basil leaves directly from the rooftop for plating or pick a basket of salad greens on demand, achieving true farm-to-table hydroponics with zero-distance from production to consumption. The system supports sustainable urban farming, local food production, and year-round fresh herb supply.

The client was highly satisfied with the overall hydroponic solution and confirmed the order on the spot. By starting with a small-scale hydroponic setup, he plans to evaluate plant growth cycles, yield stability, operational efficiency, and management costs before scaling up. For this Barcelona restaurant, this hydroponic tower system is not only a pilot project, but also a practical starting point toward building a stable, scalable urban hydroponic farming model for restaurants and commercial kitchens.
