A gutter system for use in a hydroponic system for cultivating a crop includes a gutter and an upper surface. Arranged in the upper surface are a plurality of openings which are mutually separated in a longitudinal direction of the gutter, such that the gutter forms a channel in which substrates for having crop units of the crop grow therein are placeable via the openings. The upper surface is provided at the position of each of the plurality of openings with a flange which extends substantially perpendicularly relative to the upper surface from an edge of the opening and as such forms a stop for a respective substrate of the substrates.

A drain shield for a plant container prevents compaction of soil, maintain drainage and provide for aeration of the roots of the plant. The drain shield comprises a unitary molded disk with a plurality of cube-like supports which are circumferentially spaced near the perimeter of the disk. The supports are positioned inward from the outer edge of the disk creating an eave around the perimeter of the disk that overhangs the supports. When the disk is placed on the bottom of a plant container, the supports form a series of uniform passages that lead to an unobstructed inner space under the disk. The side walls of the supports, as they relate to each other and to the center of the disk, are tapered in such a way that the passages between adjacent supports becomes larger toward the center of the disk. The underside of the disk, and to the inward side of the supports, is concave, forming a dome.

A system for the cultivation of plants, including: a cultivation table, in which the plants to be cultivated have been placed at least for the time of the growing stage; growing substrates in which the seeds of the plant are sown and which are placed at the initial end of the cultivation table for germination; and elongated troughs which hold the growing substrates in which troughs also the seeds and seedlings of the plant as well as the grown plants are placed during both said germination and said growing stage. In the method for cultivation of plants in a greenhouse, a growing substrate for the cultivation of plants is placed in an elongated trough, and seeds of a plant are sown in said growing substrate placed in the trough.

A planter includes an interior surface and a riser extending from a bottom of the interior surface and including a space between the riser and lateral walls of the planter. A top portion of the riser is configured to receive and support a plant therein.

A system having an elongated body defining a hollow passageway therethrough, which includes as a first opening disposed about a longitudinal upper half of the elongated body, and at least two second openings disposed about longitudinal side zones of the elongated body, wherein each of the at least two second opening has an area of between 80 and 700 cm.sup.2.

A paneling structure for configuring landscaping designs, living wall designs, and green wall designs. The paneling structure includes a panel structure and a planter structure that is affixed to the panel structure. The planter structure has a container like structure with sidewalls. One of the planter sidewalls include male protrusion members which engage with female members provided as openings along the front face of the panel structure to mount the planter to the panel. The panel structure further includes perimeter side edges being lined with male and female members. The male members of the panel structure engage with the female member of other panel structures to form a wall panel. An irrigation assembly may also be implemented into the paneling structure.

A plant pot 1 comprises a bounding wall 2 formed by a side wall 3 and a bottom 5 and includes a gel space 7 in which swellable gel grains 9 are accommodated filling the gel space in swollen state.

The plant pot further includes a substrate space 11 in which a substrate, for example, soil is accommodated. A bounding wall portion 2A, 2B bounds a part of the second space 11. Drainage openings 13 are located in the bottom 5 of this bounding wall portion 2B next to the gel space 7.

The first space 7 is partly bounded by a further bounding wall portion 2D, 2E of the bounding wall 2. Aeration openings 14 are located in this further bounding wall portion.

The gel grains 9 are contained in a pad which further includes a flexible separation sheet 15 which forms a root-permeable separation between the gel and soil during use.
