It is generally understood that a nutrient solution formulation should match the plant species and method of hydroponc growing. Although this has merit, it is the use factors, volume of nutrient solution applied and frequency of application that determines what the elemental content of the nutrient solution formulation should be in order to maintain plant nutrient element sufficiency. Unfortunately, little research is being done to determine what that formulation should be based on its use factors. Growers must do their own testing to determine what gives the best results in terms of plant growth and product yield and quality. Surprisingly, plants will generally grow well with a range in elemental content formulations and use factors, but when striving for maximum genetic potential growth and product yield, close matching is required. In addition, such matching can avoid nutrient element insufficiencies from occurring as well as increased efficiency in water and nutrient element reagent use.
