Abstract: The apparatus for providing nutrients to plants in a hydroponic plant growing system contains a nutrient release capsule and a capsule holder. The nutrient release capsule is a sustained release nutrient product comprising a hydroponic plant fertilizer center with a biopolymer outer coating to slow the release of the nutrients into the liquid (e.g., water). The capsule holder consists of a modifiable structure that can exist in multiple configurations to deliver different release dosage behaviors into and in response to the liquid for the hydroponic plant fertilizer.

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 housing a hydroponic system. A hydroponic system is supported by a frame and includes a water re-circulation system that provides water and other nutrients to a set of plants housed within the frame and supported by the hydroponic system. A light source is also included to illuminate the set of plants. An external plant extension is connected to the frame and extends outside of the frame, thereby providing support for an external plant placed outside of the frame and enabling illumination of the external plant by the light source of the hydroponic system. In some embodiments, the external plant may also receive water from the hydroponic system through a wick or pump coupled to the frame (directly or indirectly) in a manner the draws water from the hydroponic system and delivers the water to the external plant.

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.
