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.

- 21. A method for growing a plant comprising providing an aqueous solution comprising a pH buffered plant nutrient composition to a plant or a seed, wherein the pH buffered plant nutrient composition is capable of providing a complete set of plant nutrient ingredients for about two weeks and between about 0.2 grams and about 0.6 grams of monopotassium phosphate per liter of the aqueous solution, and wherein the pH buffered plant nutrient composition is capable of maintaining the aqueous solution at a pH of between about 3.5 and about 7.5 for about two weeks.
- 25. A pH buffered plant nutrient composition comprising a complete set of plant nutrient ingredients for growing a plant for between about one week to about 3 weeks and a buffering agent such that when said pH buffered plant nutrient composition is dissolved in water, said pH buffered plant nutrient composition is capable of maintaining the pH of water at between about 3.5 and about 7.5 for between about one week to about three weeks.
