Hydroponic Systems
A commercial hydroponic system delivers nutrient-enriched water to a soilless growing medium (or bare root) under precise EC/pH control, achieving yields 2–10× open-field for leafy greens, herbs and fruiting vegetables in a controlled environment.
NFT vs. DWC for leafy greens?
NFT dominates commercial leafy production for uniformity and labour efficiency; DWC applies where root-zone volume drives canopy performance. The RFQ captures crop and cycle. Rock-wool for uniformity and control in high-tech Venlo; coco-coir where organic certification or waste route favours it.

Role in the project
Hydroponic systems replace soil as the growth medium and are the yield engine of commercial protected cropping. Fertigation, drainage and pathogen control are engineered together with the greenhouse structure and climate.
Typical applications
- Leafy greens and herbs (NFT, DWC)
- Tomato, cucumber and pepper (rock-wool or coco-coir)
- Strawberries (table-top with substrate)
- Cannabis (rock-wool or coco-coir)
Selection criteria
NFT for leafy greens; rock-wool for tomato/cucumber; DWC and ebb-and-flow for specific programmes.
Closed-loop with disinfection or drain-to-waste — regulatory, water-cost and pathogen driven.
EC, pH, drain-EC, drain-volume, temperature and dissolved-oxygen monitoring.
Engineering considerations
Crop and growth-stage specific, adjusted to source water chemistry.
UV, slow-sand filtration or ozone by pathogen risk and cost profile.
Commercial considerations
USD 30–120/m² of growing area depending on system and automation.
Procurement considerations
Confirm substrate lead time and disposal route — often overlooked.
Common mistakes
- •Sizing tanks and drains for average, not peak, flow
- •No disinfection loop in closed systems — pathogen event wipes crop cycle
- •Nutrient recipe copied from another climate without water analysis
FAQ
Before you shortlist suppliers
- Understand the buying process first: what agricultural procurement means and how RFQs are compared .
- Awarding one turnkey contract instead of separate trades? Compare EPC contractor bids for agricultural projects on identical scope.
- For processing and grading scope, see packing house cost, sizing and certification requirements .
