A rotary plant growing apparatus has an open-ended cylindrical drum which rotates about a horizontal axis on a support stand. A lamp is positioned at the axis of the drum. Holes in the drum hold plant pots, with the plants facing the light and the bottom of the pots extending radially outward from the drum. A tray under the drum holds a pool of water and is spaced from the drum such that the lower part of the pots contacts the water as the drum rotates, watering the plants. The apparatus is particularly suitable for hydroponic gardening.
