A plantlet holder (25) is formed of nutrient solution-absorbing, open celled, phenolic foam, with an upper handling portion (55), an insertion well (60) for a plantlet and a lower portion (56) adapted to laterally locate in a ring (30) in a work stand (24), the handling portion (55) adapted to be frictionally gripped for robotic or manual handling. Robotic handling apparatus includes a pair of plantlet holder gripper manipulator arms (40) adapted to engage the handling portion (55) for movement of a plantlet holder (25) between a material source portion, an operator work portion (14), and a material delivery portion. The operator work portion (14) is characterised by the work stands (24) locating the plantlet holders vertically by a step portion (32).

An ultraviolet radiation blocking sheet for blocking ultraviolet radiation while allowing passage of visible light includes a film that is substantially transparent to light that has a wavelength of 495 to 570 nanometers. The film also is substantially absorbent of light that has a wavelength shorter than 495 nanometers. The film is configured to position between a light source and an object to be protected from ultraviolet radiation. The film absorbs the ultraviolet radiation emitted from the light source while allowing light that has a wavelength of 495 to 570 nanometers to pass through the film to illuminate the object.

A vertical planter having a partitioned tray, a liner, and a sliding wire support grid, wherein the partitioned tray engages the sliding wire support grid to provide access to the partitioned tray.

A set for assembling a length and shape adjustable planter comprising (a) a plurality of elongate troughs being length customizable by cutting thereof; the elongate troughs having a longitudinal axis and a H-inverted cross section; the elongate troughs interconnectable therebetween; (b) interconnecting members configured for interconnecting the elongate troughs in series; and (c) end members configured for mounting onto a free end of the elongate troughs. A surface of each trough at least partially is provided with a surface profile distributed over a length of the trough. The interconnecting members are securable on the surface profile.

Provided is an expandable, modular tower planter having an internal vertical composting capability, and a method of assembling and using the same. Provided in various example embodiments is a modular composting garden container system comprising a base and a plurality of stackable rings forming a tower upon the base, including an optional base ring specially sized, shaped, and positioned to connect the tower to the base. A plurality of perforated, stackable tube sections are provided that are removably assembled into a compost tube assembly of selectable height and mounted within the interior of the tower and above the base. A plurality of holding struts are sized, shaped, and positioned to removably connect the compost tube assembly with the tower and to securely locate the compost tube assembly relative to the tower. Means are provided for recovering nutrient-rich drainage and selective recovery of compost material for reintroduction into the system.

A floating garden for individually potted plants, comprising a buoyant body with a plurality of through-bores extending from the top to the bottom surfaces, the through-bores adapted to receive potted plants and potting soil. Each through-bore comprises a larger diameter upper portion and a smaller diameter lower portion aligned with each other, and a netting cup in the lower portion extending adjacent the bottom surface of the buoyant body. The netting cup holds a wicking material such as peat moss in the lower portion of the through-bore, while the upper portion of the through-bore holds potting soil and the plant.

There is disclosed a water treatment apparatus for treating stormwater, the water treatment apparatus comprising a volume of filter media, a baffle and an inlet conduit. The baffle extends upwards from the volume of filter media and defines a pre-treatment zone on one side of the baffle and a treatment zone on an opposing side of the baffle. The inlet conduit opens into the pre-treatment zone and is separated from the treatment zone by the baffle. The baffle is configured to regulate a flow of stormwater received via the inlet conduit by controlling the passage of stormwater from the pre-treatment zone to the treatment zone.
