  • the invention relates to an irrigation system for watering plants for cultivating plants indoors, in particular in a climatically sealed climate cell, the irrigation system having at least one inlet line and at least one distribution line fluidically connected to the inlet line.
  • the invention relates to a climatically sealed climate cell for cultivating plants indoors.
  • DE 1 928 939 describes a climatic chamber for growing plants indoors.
  • DE 1 778 624 describes a device for conditioning air for a climatic chamber.
  • the object of the present invention is to provide an irrigation system for watering plants for growing plants indoors, in particular in a climatically closed climate cell, as flexible as possible and for a substantially automated cultivation.
  • an irrigation system for watering plants for cultivating plants indoors in particular in a climatically sealed climate cell, is provided for this purpose, the irrigation system having at least one inlet line and at least one distribution line fluidically connected to the inlet line.
  • a plurality of water outlet units fluidly connected to the distribution line are arranged along the distribution line.
  • the irrigation system for watering plants is preferably intended for use in a system for indoor vertical plant cultivation.
  • the vertical cultivation of plants indoors also includes what is known as indoor vertical farming.
  • the environment around the plants must be optimally adjusted in terms of climate, which is why compact climate cells with the minimum required volume are ideally used.
  • Several layers, each with several rows of plants, are arranged within the climate cell.
  • the irrigation system for watering plants is preferably designed for several layers arranged one above the other, each with several rows of plants arranged next to one another.
  • irrigation or plant irrigation is to be understood as meaning the supply of water and/or a nutrient solution.
  • the supply line is the connection or the connection to the water supply. This can for example be realized by means of a pipe, a hose or the like.
  • the distribution line is fluidly connected to the feed line.
  • the distribution line serves as a guide along a row of plants and can also be designed as a tube, hose or the like.
  • the feed line and distribution line can be separate lines connected to each other by suitable connectors. Alternatively, the supply line and the distribution line could also be just sections of a single conductor.
  • the water outlet units are arranged along and fluidly connected to the manifold.
  • the water outlet units serve to discharge the water or nutrient solution into the containers in which the plants are placed.
  • trough-shaped containers so-called carrier systems
  • the trough-shaped containers i.e. the carrier systems, are used to hold and direct the water or the nutrient solution.
  • the liquid is then discharged into the carrier systems by means of the water outlet units.
  • the water outlet units are preferably designed as flexible hoses.
  • the distributor line is preferably guided in or on a substantially horizontally aligned and elongated receptacle.
  • a receptacle can be understood to mean, for example, a channel or rail for guiding the distribution line.
  • the distribution line is preferably aligned along a row of plants or a row with carrier systems on a layer. Accordingly, the recording is also aligned along a row of plants or a row with carrier systems on one layer.
  • the water outlet unit preferably has a flexible hose.
  • This can be understood to mean a piece of tubing.
  • flexible is to be understood as meaning a tube or tube piece which is at least slightly flexible and relatively easy to position and can be adjusted if necessary.
  • the distribution line could, but does not have to, be more rigid, for example tubular.
  • the water outlet unit has a holder for receiving and for positioning a water outlet of the water outlet unit.

  • the holder is preferably arranged or can be arranged in a displaceable or displaceable manner in a longitudinal direction along the distributor line.
  • the position of the precise water delivery can be set, changed and/or adjusted with the holder. This means in particular that the position can be adjusted and positioned in the longitudinal direction along a row of plants or a row with carrier systems. This makes it possible to define and predetermine the exact position of the liquid delivery into the respective carrier systems arranged one behind the other in a row.
  • the carrier systems with the substrate carriers arranged therein or the plants arranged therein are optionally or regularly displaced in the longitudinal direction. It is therefore of great importance that the holder and thus the exact position of the water outlet can be precisely adjusted.
  • the irrigation system preferably has sensors for detecting a leak. In this way, an undesired discharge of water or the discharge of the nutrient liquid can be detected in good time. Using these sensors, the leak in one of the conductors, for example in the distribution line, but also a leak in or on the hose connectors are detected.

  • a plurality of substrate carriers are preferably arranged or can be arranged in each carrier system, with each substrate carrier having a receiving area with a substrate arranged therein or which can be arranged therein for receiving the plants and/or for receiving seeds.
  • the substrate carriers are preferably arranged one behind the other within the carrier system, ie along the same row as the carrier systems themselves. Provision is also preferably made for each row to be assigned at least one distribution line of the irrigation system, with each carrier system being assigned at least one water outlet unit.
  • the distribution line can be arranged or run along a row of plants or a row with substrate carriers, as well as laterally and somewhat higher than the upper edge of an edge of the substrate carrier.
  • the liquid is preferably released via the water outlet units into the carrier systems and not into the substrate carrier or onto the plants themselves.
  • the substrate carrier on the other hand, floats or stands within the carrier system in the liquid. The carrier systems thus also serve to guide the liquid.
  • the water outlet units are adjusted or positioned by means of the holders in such a way that they discharge the liquid into an intermediate space between the outer edge of the carrier systems and the substrate carriers arranged in the carrier systems. It is important that no air gets under the substrate, for example a membrane.
  • the substrate carriers are shifted along the row relative to the water outlet units.
  • the water outlet units can be moved, adjusted or adjusted in the longitudinal direction, but essentially remain in a fixed position along the row, in contrast to the carrier systems.

  • the openings can be designed as holes in the shading means, for example the sheet metal.
  • the water outlet units are aligned exactly according to the openings in the shading means or the shading means.
  • the irrigation system in particular the water outlet units of the irrigation system, are arranged and designed without connection and in particular without contact with the carrier systems.
  • no fixed connection is provided between the carrier systems and the irrigation system or the water outlet units of the irrigation system.
  • the water outlet units are preferably attached to the receptacle for the distribution line by means of the holders in the longitudinal direction along the rows and are precisely aligned in accordance with the openings in the shading means or the shading means.
  • the climatically sealed climate cell preferably has regulating means for regulating a temperature and/or a relative humidity and/or a carbon dioxide content and/or an air speed and/or a watering duration and/or a lighting duration and/or a lighting intensity within the climate cell.
  • the climatic cell can be designed in such a way that uniform parameters are set within the entire climatic cell by means of these regulating means.
  • the climatic cell could be designed in such a way that the parameters for the individual layers can be set individually by means of these regulating means.
  • the climate cell is divided into several climate zones in the horizontal direction, in particular in the direction of the rows of plants arranged on the individual layers.
  • a climatic cell configured in this way is particularly suitable when the plants or the carrier systems with the plants arranged on them are pushed through along the rows on the individual layers in a kind of FIFO principle during the germination and/or growth phase.
