Ancillary embodiments and modifications to a homogenizer unit (“PPH”), and methods of use directed to hydroponics. The apparatus includes a homogenizer body, one or more nutrient stream inlets, one or more water inlets, a mixing zone where the water stream is commingled with the nutrient stream, and a venturi within the body immediately downstream from the mixing zone such that the commingled streams are pulled into the venturi resulting in homogenization. The PPH components are insulated to maintain the aqueous nutrient solution at a cooled, below ambient temperature. Because the prepared aqueous nutrient solution is cooled, it may also have oxygen and/or nitrogen gas dissolved therein (e.g., introduced into one of the streams introduced into the PPH). The resulting aqueous nutrient solution can be conveyed in its cooled state to roots of hydroponically grown plants to provide nutrients for the growth of the plants.
