The City of Phoenix held a government meeting on July 31, 2025, focusing on the operational aspects of the Assembled & Running System, particularly regarding the proper use of water pumps and fertilizer in hydroponic systems.

During the meeting, officials discussed the setup and adjustments necessary for the water pump, emphasizing the importance of ensuring the system is balanced and free from excessive gurgling sounds. Participants noted that the water pump's flow can be adjusted through various valves, and air stones are utilized to maintain oxygen levels in the water.

The discussion also highlighted the significance of monitoring the pH levels of the water before adding fertilizers. A calibrated pH meter was used to demonstrate that the water's pH was around 7.8 to 7.9, which is crucial for determining the appropriate amount of acid needed to adjust the pH for optimal plant growth.

Officials stressed the importance of using only fertilizers and chemicals specifically designed for hydroponic systems, warning against the use of any organic materials or products intended for traditional soil gardening. The meeting concluded with a demonstration of how to properly add fertilizer to the system, ensuring it would distribute evenly throughout the water.

This meeting underscored the City of Phoenix's commitment to promoting effective hydroponic practices, ensuring that residents are equipped with the knowledge to maintain their systems efficiently. Future discussions may focus on further refining these practices and addressing any emerging challenges in hydroponic gardening.
