This invention provides a container and associated growing process that promotes the growth of at least two different, specialized types of roots and that provides the optimal conditions for these two types of roots. In particular, the container defines an upper section that promotes growth of a fine intricate web of roots that is surrounded by an organic, non-organic or mixed organic and non-organic nutrient-rich medium. This upper section is separated by a permeable medium divider that allows predetermined quantities of water to pass into the upper section (to maintain desired moisture in the nutrient medium (soil), while a lower / bottom section contains a reservoir of hydroponic water that may be relatively free of any nutrients (e.g. “non-nutrient” water). Extending from the upper root ball are a series of water-drinking straw-like roots that transpire water directly from the non-nutrient reservoir and that are continually exposed to massive amounts of atmospheric oxygen. A transport (capillary) device allows water to wick from the reservoir into the upper section to maintain a desired level of moisture in the upper roots, and carrying with it additional dissolved oxygen via evaporation and transpiration. The bottom section can be filled with an acceptable porous, water-storing medium such as gravel or rock wool. The permeable medium divider can include one or more capillary devices that allow transfer of water from the lower reservoir into the upper section. In certain embodiments, the divider can include a series of formations that allow it to sit in an elevated manner on a water-containing structure (such as a sponge-like medium).
