As global water resources become increasingly scarce, commercial growers are seeking irrigation alternatives that dramatically reduce water consumption while maintaining or increasing crop yields. NFT hydroponic systems have emerged as the leading solution for soilless agriculture, offering water savings of up to 90% compared to traditional field farming.
NFT stands for Nutrient Film Technique, a hydroponic method in which a very shallow stream of nutrient solution is recirculated past the bare roots of crops grown in inclined channels. The film is typically only a few millimeters deep: the roots receive constant moisture and nutrition while the upper root zone stays oxygenated. Because the solution is recirculated in a closed loop, water use drops by up to 90% versus open-field irrigation.
Commercial NFT hydroponic systems pair the channels with reservoirs, pumps, filtration and EC/pH controllers. G AND N FORTUNE manufactures the complete channel line – 100x50mm lettuce channels, 73x62mm MGS moving gutters and 150x100mm substrate channels – in its own 5,000 m2 factory in Dongguan, China.
First, water and nutrient efficiency: closed-loop recirculation saves up to 90% of water and around 50% of fertilizer. Second, density and speed: channels are laid at high density with fixed hole spacing, cutting growing cycles for lettuce and leafy greens to as little as 30-40 days. Third, hygiene: soilless cultivation eliminates soil-borne diseases and most pesticide use.
Finally, scalability. NFT systems scale from 200 m2 pilot greenhouses to multi-hectare facilities, and they integrate naturally with automation – moving gutters (MGS), nutrient controllers and harvest logistics. That is why our systems now operate in more than 70 countries, from Middle East water-saving programs to Southeast Asian typhoon-rated greenhouses.
Up to 90% compared with traditional field farming, because the nutrient solution recirculates in a closed loop instead of draining into soil.
NFT is one of the simplest commercial systems to operate once commissioned. Our turnkey packages include manuals, protocols and remote growing support.
Lettuce, pak choi, herbs and kale are ideal in 100x50mm channels; tomato and cucumber are better served by 150x100mm substrate channels or Dutch buckets.
