Vertical Farming Technology

GCT's vertical farming technology provides communities with the ability to grow year-round in any indoor facility or greenhouse and not limited to a specific location. GCT believes that providing our clients with additional means of growing technologies will provide regionally food stability year-round.


  • Optimal Light Usage

  • Advanced Water Technology

  • Optimizing Production Technology


  • Responsible and economical water management starts with the correct pre-treatment of water. Everything that can be done at the entry-level does not need to be handled and corrected afterwards at the nursery. Therefore, it is important that entering water is free of organisms to ensure better disease control and reduce bicarbonates for a stable pH at your crop.


Surface water disinfection with UV light

  • UV disinfection systems destroy all existing organisms such as fungi, bacteria, and viruses in the irrigation water. The system can be applied for both new entry water and recycled drain water.


Stable pH with bicarbonate removal

  • When using ground-, river- and drinking water, an excessive concentration of bicarbonates may be present in the supply water. This influences the pH of your fertilizer dosing unit and the pH at the location of the drippers may rise substantially. Bicarbonate reduction helps to achieve a stable pH. 



  • You want to be able to administer the right concentrations and ratios of nutrients to achieve growth. Whatever the needs of your crops, fertilizer dosing must be flexible and reliable. GCT manages this with stable EC and pH controls. At the correct pH, the plants absorb the fertilizers effectively and a stable EC ensures better growth of your crop and a longer shelf-life in the supply chain.



  • With GCT's sophisticated irrigation monitoring system, you know the exact drain percentage and even have the plant itself determine the time at which watering takes place. The result: a healthy root system with a higher yield. Essentially, watering is tuned to the growing circumstances, the state of the crop, and the type of substrate.


Post-treatment and drain water recycling

  • The drain water is collected, filtered, and then stored in the ‘dirty’ drain water basin. As a precautionary measure, the drain water is then disinfected by the UV disinfection systems. This allows continuous recirculation of irrigation water in a safe way. As a result, expensive fertilizers are not flushed down the drain and do not contaminate the environment.

  • A sustainable environment with healthy surface water is becoming more and more important. Laws and regulations demand the treatment of effluent water before it is discharged to surface waters or the sewage system. You can treat this water to break down more than 95% of crop protection agents.

  • The EC pre-mixing allows you to reuse the drain water to the greatest possible extent; this is mixed with the necessary ratio of freshwater before fertilizers are added.



  • You want to check and control the watering of your crop as accurately as possible. The correct EC and pH are essential factors for the healthy growth of your crop. Measuring both the EC and the pH as well as the flow, accurately allows you to give your crop the right amount of nutrients. GCT supplies a range of sensors you can use to ensure the watering system starts at exactly the right time. This gives you more control over your crop, the production and together with this, naturally, your yield
