This work presents provide information about the most common aspects to consider in the replace or maintenance of nutrient solution in commercial hidroponics. The information allow the evaluation of the concentration of nutrient solution used in hidroponics of several agricultural and commercial species, taking into consideration aspects which refer to the maintenance of solution phi and the monitoring of nutrient solution considering several criterion like maximum nutrient depletion, electrical conductivity, nutrient absorption curves, ions influx, solar radiation and also the monitoring of nutrient solution for NFT system and their use in research studies.
