The present invention relates in general to pots and, in particular, to a system, method and apparatus for drainage collection pots for plants.
Description of the Related Art
Drainage collection from potted plants is valuable for growers that wish to control the disposal of waste water (drainage) for environmental protection, or to reuse the solution which contains salt and fertilizer. Generally, the drainage is collected into holding ponds where solids precipitate out, or it is diluted with clean water and then applied to in-ground crops. Alternatively, in the case of very dry environments, it is reused after passing through or mixing with water that has passed through a reverse osmosis system.
On a larger scale, this type of drainage is potentially a kind of environmental pollution if allowed to flow into rivers, streams and groundwater. Fertilizer from golf courses and other agriculture is already being blamed for algae blooms. Several countries, especially in Europe, have passed regulations that require growers to collect waste water that contains fertilizer. These regulations will start to be enforced within several years in some countries.
Some growers place their pots in wide gutters to collect drainage. However, wide gutters have some disadvantages. For example, a gutter as wide as or wider than the pot is expensive and requires near-perfect grading over a large area. In addition, evaporation occurs in wide gutters. Evaporation wastes water and increases the humidity within greenhouses, which can effect flowering, fruiting and encourage some diseases. Leaves and other debris also can more readily accumulate in wide gutters, which impedes flow through the gutter and causes water to pool. Thus, improvements in containers for plants continue to be of interest.
Embodiments of a container for a plant may include a base having an axis, a width transverse to the axis, a bottom, and a sidewall extending axially upward from and circumscribing the base. A tier of holes may be formed in the base. The holes in the tier may span a substantially entire width of the base. In addition, the tier of holes may be located at a substantially lowest elevation of the base to define a trough at the bottom of the base.
Another version of a container may include a base having an axis, a sidewall extending axially upward from and circumscribing the base, and a bottom having an upper elevation and a lower elevation that is axially lower than the upper elevation. The lower elevation may define a trough at a central and lowest-most portion of the base. A first set of holes may be formed in the trough at the lower elevation, and may be configured to permit liquid drainage from the container. A second set of holes may be formed in the upper elevation and configured to substantially only permit air uptake to roots of a plant in the container, and configured to not facilitate liquid drainage from the container.
One embodiment of a container may include a base having an axis, a width transverse to the axis, a bottom with holes, a sidewall extending axially upward from and circumscribing the base, a plurality of legs extending below lowest-most holes in the base, and feet connecting the plurality of legs. The container may include only two feet, and half of the legs may be coupled to each foot.
An alternate example of a container may include a body that is hollow and has an open top and an open bottom, each with no closure. The open top and the open bottom may be similar in size. In addition, a tray may be configured to seat inside the body adjacent the open bottom of the container to substantially close the open bottom.

The embodiments described herein may have advantages over prior art designs. For example, the present designs favorably utilize water surface tension to collect drainage from the containers in a cost effective matter, while allowing oxygen uptake in the roots. When the plant substrate within the container is properly moist but not oversaturated, no drainage may originate from the holes at the highest vertical elevation. Rather, drainage may originate only from the holes at the lowest vertical elevation. This is due to the pressure being higher on the lower holes. Therefore, the surface tension prevents drainage from the higher holes of the containers.
In another embodiment, the tray or base may be modified to have only a single hole at the lowest elevation, such as a trough. In addition, the gutter could be a pipe, such that the single hole drains into the pipe.
