HYDRATION SYSTEM FOR AN INDOOR GARDEN CENTER

A gardening appliance includes a liner positioned within a cabinet and defining a grow chamber, a grow tower rotatably mounted within the liner and defining a root chamber, a primary water supply system for selectively providing freshwater into the root chamber, and an auxiliary water supply system comprising a wastewater tank for storing wastewater and selectively providing the wastewater into the root chamber. A controller is configured to determine that a hydration cycle needs to be performed to hydrate the one or more plant pods, determine that a freshwater supply limitation exists (e.g., an empty water supply tank or a full wastewater tank), and operate the auxiliary water supply system to provide the wastewater from the wastewater tank into the root chamber in response to determining that the freshwater supply limitation exists when the hydration cycle is needed.
