ABSTRACT:
This invention provides pH buffered plant nutrient compositions, methods for fertilizing a plant growing or a seed germinating in a hydroponics system, methods for growing a plant in a hydroponics system, and methods for making a pH buffered plant nutrient composition. The compositions and methods of this invention are useful with distilled water, deionized water, filtered water, and United States municipal tap water. The compositions and methods of this invention are useful with most of the municipal water supplies in the United States. pH buffering agents useful in the practice of this invention include phosphate buffers, aquarium buffers, 2-[N-morpholino]ethanesulfonic acid, and mixtures thereof.
