In order to evaluate the nutritional supply of lettuce seedlings (second transplant) in an NFT hydroponic system of its own construction, it was taken as an observable reference, to measure the consumption and to replace the missing aliquot of nutrients as a whole and from these data, Establish the trend that follows this process. The concentration of salts dissolved in water must be kept constant, replenishing the nutrients consumed. Initiated the culture, the concentration measurements have allowed to find a relationship between the percentage of nutrients and the relative concentration, which is appreciably lowerthan the initial concentration.
