Agrifirst NFT (Nutrient Film Technique) Hydroponics System is a premium commercial hydroponic solution where a thin, continuous film of nutrient-rich water flows through enclosed growing channels, bathing plant roots in perfectly balanced nutrition and oxygen. This system produces the highest yields per square meter of any hydroponic method for leafy greens, herbs, and small fruiting crops.
How NFT Works
Plants sit in net pots within holes in enclosed PVC/food-grade channels set at a slight gradient (1–3%). A pump delivers nutrient solution from a central reservoir to the high end of each channel. The solution flows as a thin film (2–3mm) along the channel bottom, contacting plant roots before draining back to the reservoir for recirculation. Roots are exposed to both the nutrient solution and air simultaneously — creating ideal conditions for rapid, healthy growth.
Key Benefits
- 10x Higher Yield — Produces up to 10x more crop per square meter compared to soil-based farming through dense planting and rapid growth cycles
- 90% Water Savings — Closed-loop recirculation system conserves water dramatically compared to conventional irrigation
- Rapid Harvest Cycles — Lettuce ready in 25–30 days, herbs in 20–25 days — enabling 12–15 harvests per year
- Zero Soil Required — No soil-borne diseases, no weeding, no soil preparation — clean, hygienic produce
- Vertical Stacking — NFT channels can be stacked in A-frame or multi-tier configurations for even higher space efficiency
- Premium Market Pricing — Hydroponically grown produce commands 2–3x higher prices in urban retail, restaurants, and supermarkets
