Siemens SIMATIC × LindenGreen: Container Hydroponics Oct 2026

A shipping container that grows lettuce needs factory-grade control. On October 2, 2026, VerticalFarmDaily published Siemens’ case on Czech startup LindenGreen.

GreenBox / Urbi

• GreenBox: hydroponic vertical farm in a customer-configured container
• Urbi: smaller indoor variant without the container shell
• Claimed outcomes vs field farming: up to 90% less water, 70% less fertilizer, up to 3,200 lettuce heads/month per farm

SIMATIC stack

Core controller: SIMATIC S7-1200 tying temperature, humidity, nutrient EC sensors to ventilation, circulation, dosing, and lighting. Operators use a SIMATIC HMI Unified Comfort Panel; remote support runs through SIMATIC WinCC Unified in a browser. Engineering sits in TIA Portal.

CEO Dmitrij Lipovský says installations span 10+ countries on three continents, including a large Seychelles hydroponic farm this summer, a Spain onion-research GreenBox in October 2026, and further Ukraine deliveries this year.

Why a PLC belongs in a salad box

Container CEA has to recreate climate that fields get for free. LindenGreen’s S7-1200 loop closes on temperature, humidity, and nutrient electrical conductivity while coordinating ventilation, water circulation, fertilizer dosing, and per-rack lighting programs selectable on the Unified Comfort Panel. WinCC Unified lets specialists coach crops remotely—Jan Vokál (operations) frames that as both customer support and a path to lower energy/resource footprints.

Siemens and LindenGreen are candid about vertical farming limits: high energy use, CapEx, technical complexity, power dependence, and a narrow set of economically viable crops. Their bet is targeted capacity near demand—not replacing open-field agriculture wholesale. The Spain onion-research GreenBox dated for October 2026 and Ukraine installs are concrete near-term deployments named by CEO Dmitrij Lipovský.

Is this DIY kit pricing? No public consumer MSRP in the article—industrial/project sales.

Does it replace field farms? LindenGreen and Siemens frame it as complementary capacity where land/water are constrained.
