Abstract
A channel culture device of a type which provides multiple plant growth channels is made of a plurality of modules each having a horizontal base wall joining a pair of perforated side walls which extend upwardly and are inclined toward one another to define an interior channel of trapezoidal cross-section, having a relatively narrow opening at the top. A row of modules is placed end-to-end to define a storage channel, used primarily for moisture reserve. Placing a series of rows side-by-side in lateral abutment defines V-shaped plant growth channels between adjacent modules, and these are supplied with moisture through the perforated side walls. Various partitions may be placed within the modules to subdivide them into growth, storage, and drainage channels.
