An indoor-outdoor garden unit including a basin having an overhead canopy, connected to a water source via a main water tube and holding a plurality of opaque growing trays with removable opaque lids for optimal sprout growth in the dark. The main water supply tube operationally communicates with an on-off timer controlling water cycles. Bottom holes in each growing tray allow water, infused into the basin by any of three selectable mechanisms, to flow upwardly to water the sprouts from underneath, and serve to drain water from the growing trays and to aerate the plants between watering cycles. Sprayers on the underside of each growing tray lid allow watering from the top side. Water can be infused into the basin by the direct basin fill inlet or by a water fountain from which water impacts a water catcher member undermounted on the canopy to shed droplets into the basin.
