Abstract: A hydroponic growing system is presented. The system can include multiple growing trays in a vertical arrangement, where a pump supplies the top-most tray and each lower tray is supplied by the overlying tray, and where the plumbing elements for supply and drainage are arranged to one side of the system. The system includes variations to support different crop types within the same system, including removable growing structures for root vegetable, microgreens and supports for vining crops. The system can monitor and adjust the nutrients and other features of the systems water profile to concurrently group multiple crops in differing developing stages.

Abstract: The disclosure relates to technology for hydroponics. An aspect includes a hydroponic system comprising a tray having a drain opening in a bottom of the tray. The hydroponic system comprises a water re-circulation system configured to re-circulate water containing plant nutrients through the hydroponic system. The water re-circulation system is configured to provide the water containing the plant nutrients to the tray. The tray is configured to convey the water along the bottom the tray to the drain opening, the drain opening configured to drain the water from the tray. The hydroponic system comprises different types of removable growing structures that are configured to provide corresponding different vertical distances between a top of a hydroponic growing medium and the bottom of the tray.

Abstract: The disclosure relates to technology for hydroponics. One aspect includes a computing system comprising a network interface, and a processor coupled to the network interface. The processor is configured to receive plant observations over the network interface from a plurality of electronic devices. The plant observations are for a type of crop being grown in respective hydroponic systems. The processor is configured is modify a technique for determining a water profile based on the plant observations, the water profile for growing the type of crop in a hydroponic system. The processor is configured to determine a target water profile for growing crops in a target hydroponic system based on the modified technique, the crops in the target hydroponic system include the type of crop. The processor is configured to provide the target water profile over the network interface to a requesting electronic device.
