Lettuce cultivation in the Nutrient Film Technique (NFT) system is most commonly used in all climatic zones. In the experiment performed at University of Agronomic Sciences and Veterinary Medicine of Bucharest, Hortinvest greenhouses, on lettuce culture in the NFT system we monitored the debit and oxygen content of the nutrient solution at the roots of lettuce plants and found that depending on its flow rate, the configuration the root system was different. We also found that there were correlations between the size of the root system and the mass of lettuce plants obtained in this system.
