From DFT and NFT systems to full automation, validated by real-world results like Berkshire with higher output, lower labor, and a scalable production model
Deep Flow Technique (DFT) is a hydroponic system in which plants grow in a continuously flowing layer of nutrient-rich water. This ensures that the roots have constant access to water, oxygen, and nutrients.
The larger water volume helps maintain stable conditions, resulting in uniform growth and strong plants. DFT is therefore highly suitable for the propagation of crops such as leafy greens.
In combination with automation from Flier Systems, the process is precisely controlled and optimized for maximum efficiency and plant quality.
With the Nutrient Film Technique, a thin film of nutrient solution flows continuously past the plant roots. This ensures optimal oxygen uptake and a high germination rate.
The NFT line from Flier Systems combines uniform sowing quality with significant labour savings — fully automated from start to finish.
Berkshire Produce transformed an existing greenhouse into a modern hydroponic lettuce facility using Deep Flow Technique and targeted automation.
By redesigning and optimizing the process, Berkshire achieved higher production, improved stability, and reduced losses. At the same time, manual labor was reduced and internal logistics were made more efficient.
This case demonstrates that hydroponic cultivation, when properly designed, is scalable and can deliver strong economic performance.
From substrate preparation and seeding to transplanting, growing, transport, and harvest handling, each stage is integrated into a continuous automated flow.
Centralized software manages planning, timing, and process coordination, creating transparency and predictability across the entire production system.
Operators supervise the system rather than perform repetitive physical tasks. This reduces labour intensity while improving consistency and scalability.
