Abstract
A rotary growing apparatus comprises a cylindrical structure or drum provided with a series of parallel elongated, longitudinally extending, baskets adapted to receive therein the plants to be grown. A support base is provided for the drum, and a drive mechanism is adapted to rotate the drum on the support base about a rotational axis of the drum. At least one light source extends inside the drum about which the drum and the plants carried thereby can rotate. A feeding system provides nutrient fluid to the growing plants as the drum rotates and the baskets contact the nutrient fluid. The elongated baskets each include a bottom wall and a pair of side walls and are capable of receiving therein a series of plants supported by a growing medium. The elongated baskets define in the bottom and side walls thereof a plurality of apertures for allowing the nutrient fluid to access the plants. The elongated baskets are removably attached to a pair of parallel and opposed rims of the drum.
