A waterway structure for a flowerpot stand is disclosed. The flowerpot stand is assembled with a waterway device, including plural poles, plural bearing elements and a waterway device. Each pole is provided with an external assembly board, plural through-holes and a lower through-hole. The bearing element provides for placing a flowerpot, the waterway device is provided with plural lower water hoses and plural upper water hoses, the lower water hose is connected at a bottom of the pole, and the upper water hose is connected at a position above the pole. The pole is used as a support structure and also for a water source to flow through. Through the lower water hose, the water source enters into the connected poles and flow to the upper hoses, and is then poured into the flowerpots from the upper water hoses.

A plumbing system and water transport method. The system includes a global water source, a one way water transport mechanism, a growing tray, and a local buffer. The local buffer separates the global water source and the growing tray to prevent cross-contamination of water. The local buffer also continuously provides water to the growing tray on demand without the need for filtering or dumping of used or excess water. This results in low flow, efficient water transport.

The invention is a vertically stacked flood-and-drain growing system in which chambers are arranged in sequence to ensure complete root saturation throughout the vertical tower. Water from an upper reservoir enters the top chamber and flows downward via siphons that control flooding and draining from one chamber to the next. Each siphon is configured with a larger upflow opening and a smaller outflow opening to regulate water movement, and the siphon apex includes an opening with a removable plug to permit cleaning and maintenance. By filling only the top reservoir, water is distributed successively through all chambers, thereby delivering thorough and uniform hydration to plant roots while maintaining proper aeration.

A mobile robot configured for integration with one or more grow space components within a grow space that includes one or more grow modules, the mobile robot including: one or more sensors; a mobility mechanism; a processor; a memory; the mobile robot configured to: determine, by the mobile robot, that a grow space operation should be performed in the grow space; and based on the determination, perform, by the mobile robot, the grow space operation by integrating with at least one other component in the grow space.
