An apparatus for growing plants in a plurality of rotatable, cylindrical drums, in which plants grow radially inwardly of the drum, has support means, such as rails, worm gears or a Ferris wheel-type structure, to support the drums for movement from one part of the apparatus to the other. The apparatus has means to rotate the drums about their axis as they are moved through the apparatus, and means to provide water to the plants as the drums move and rotate. |
