NFT Nutrient Film Technique This is the most popular hydroponic system nowadays, and hidroppnia people, whenever referring hidroponia nft hydroponics, immediate relate it to it. Effect of salinity and oxygen level on lettuce grown in a floating system. As with all active hydroponic systems, attention hidroponia nft be paid hidroponia nft the dependence on electricity and protect the system against possible failures that might occur, for instance, by adapting a suitable culture medium. In small plants culture, the channel is usually replaced by a rectangular section tube.
How to cite this article. AThe nutrient solution is pumped from a tank into a culture channel and flows constantly on its bottom in the form of a very thin film. Experimental structure for evaluation of saline water use in lettuce hydroponic production.
