A manifold for a hydroponic system comprises a main body, an inlet port, an outlet port, and an electrical conductivity probe. The main body defines a dosing chamber and comprises at least one dosing port in fluid communication with the dosing chamber. The at least one dosing port is configured to facilitate introduction of dosing fluid to the dosing chamber. The inlet port is coupled with the main body and is in fluid communication with the dosing chamber. The outlet port is coupled with the main body and is in fluid communication with the dosing chamber. The electrical conductivity probe is coupled with the main body and extends into the dosing chamber downstream of the at least one dosing port. The electrical conductivity probe is configured to detect an electrical conductivity of a hydroponic fluid contained in the dosing chamber. A hydroponic system and methods are also provided.

A nutriculture device includes: a culture bed having an upward facing opening; a planting panel that covers the opening of the culture bed, includes a through hole having a crop pass therethrough, and defines an internal space between the cover and the culture bed; a water retention mat inside the internal space and that retains water; a plurality of culture containers each of which supports the crop, each of which is arranged in the internal space, and each of which is provided with a bottom hole; a medium housed in each culture container; a mat-side water irrigation unit feeding water to the water retention mat; and a container-side water irrigation unit feeding water into each of the culture containers per container unit including some of the culture containers or per culture container. The nutriculture device with this configuration can cultivate high-quality crops while suppressing generated drainage water.

A plant treatment apparatus includes: a plant holding unit; an ultraviolet irradiation unit configured to irradiate a plant held by the plant holding unit with light comprising ultraviolet light in a wavelength range of no less than 270 nm and no more than 290 nm; and either (i) a plant immersion unit configured to immerse the plant held by the plant holding unit into a liquid that comprises water and is held by the plant immersion unit, or (ii) a liquid ejection unit that ejects the liquid towards the plant held by the plant holding unit.

A system for hydroponic cultivation including a cultivation container that includes an outer bucket having a drain defined in a lower portion. The outer bucket is configured to receive and support a perforated insert for holding a growing medium and tin a root mass/ball of a plant. The cultivation system also includes an elongated trough having an upper portion and a lower portion. The trough defines a longitudinal irrigation channel inclined downwards from a first end towards a second end. The upper portion forms shoulders on opposing sides of the trough for receiving the cultivation container. An irrigation system is also provided to deliver a hydroponic solution to the plant, which includes a delivery unit associated with the cultivation container and is configured to deliver the hydroponic solution to the plant from an upper portion of the cultivation container. A lighting system is also provided to deliver light to portion and side canopies of the plant.
