An indoor gardening appliance includes a grow module positioned within a grow chamber for receiving one or more plant pods. The indoor gardening system includes a hydration system including a water supply for providing a flow of water into a mixing tank and a discharge nozzle for selectively discharging the flow of water into the grow chamber. The indoor gardening appliance further includes a cleaning assembly fluidly coupled to the hydration system for selectively discharging a cleaning agent into the flow of water to create a cleaning solution to facilitate a self-clean cycle.
