Definitions
- Above-ground cultivation rack unit particularly intended to be included in such a shelving, an above-ground culture module comprising such a unit and an above-ground culture system comprising at least two such racks.
- the present invention relates to the field of soil-less cultivation, which encompasses in particular hydroponics and aeroponics.
- the invention relates to a system of soilless cultivation.
- Soil-less cultivation unlike the so-called traditional culture, consists mainly of doing without earthy soil, in order to provide plants directly and only with the nutrients, also called inputs, which they need, with increased control over traditional culture.
- the advantages of soilless cultivation are numerous. In particular, the yields are increased, and the risks of disease are limited. The use of treatments to cure or prevent disease is thus also limited.
- the field of soilless culture includes, but is not limited to, hydroponics and aeroponics.
- Hydroponics consists of using an inert substrate in which the roots of plants develop, and irrigating the substrate with a nutrient solution including the inputs. Aeroponics dispenses with the substrate, and plant roots develop in the air. The inputs are then for example sprinkled on the roots.
- Low pressure aeroponic systems are the most widely used systems today. They are characterized in particular by the fact that the nutrient solution is sprayed through nozzles by a water pump having, generally, a high flow rate but delivering a low pressure. They correspond to an evolution of hydroponic systems where the irrigation system has been replaced.
- the high pressure employs nozzles aimed at misting the nutrient solution on the root system.
- This mist is made up of droplets, for example having a size of about fifty microns. This figure is recognized to be close to the size of the pores located on the roots of plants.
- the plants' assimilation capacity is maximum and the exchange between the roots and its propagation medium is optimized.
- Soil-less cultivation is of particular interest in regions where the climate makes traditional cultivation particularly complicated, if not impossible, due to the absence of cultivable soils and / or extreme temperatures and / or large climatic variations. .

- the shelving can be set up in any location.
- the closed shelving configuration isolates plants from the outside environment, so the environment does not need to be precisely controlled.
- the shelving makes it possible to form as many culture chambers as desired, for example by increasing the number of units and / or culture compartments per unit
- the sealing system may include a device for pressurizing the culture chamber and / or at least one seal extending around the culture chamber, when the shelving is in the closed configuration.

- the nutrient solution is then sprayed into the culture compartment 307, preferably on the root side 310 using a pump 329.
- a filter 330 is interposed between the nutrient solution reservoir 328 and the pump 329 in order to avoid s' ensure that only particles smaller than a determined size reach the culture compartment 307.
- the pump 329 is associated with a booster 331 in order to ensure the spraying of the nutrient solution in the form of droplets of determined dimensions.
- the regulation system 316 is for this purpose connected to a pressure sensor 332 and a flow controller 333 at the inlet of the culture compartment 307
- the control system 316 can also be connected to a set 334 of sensors to monitor the nutrient solution in the reservoir 328, for example the temperature, the pH, the electroconductivity and the input composition of the solution. .
- the regulation system 316 then operates taking into account the information transmitted by the sensors 317, 318, 319, 320, 321 in the culture compartment 307 in order to adjust the characteristics of the atmosphere in the culture compartment 307 , in particular the power of the ventilation device 325, of the lighting device 322 or of a temperature control device according to a predetermined control command.
- the regulation system 316 can also perform regulation of the composition of the nutrient solution, for example based on sensor data, and / or based on a recorded regulation cycle. To this end, the regulation system 316 regulates the distributor 327 so that the composition of the nutrient solution in the reservoir 328 has the expected characteristics, in particular on the basis of the information transmitted by the set 334 of sensors. The nutrient solution with determined characteristics is then pumped and sprayed into culture compartment 307. The regulation system 316, from the data of the pressure sensor 322 and the state of the flow controller 33, makes it possible to regulate the power of the pump 329.
- the culture compartment 307 may include a recuperator for the excess nutrient solution, in order to reinject it into the nutrient solution reservoir 328 after possible passage through a filter 335.
- the regulation system 316 may be common to several units 300, or even to all of the units of the culture system 100. To this end, each unit can be identified in the regulation system 316, and the regulation setpoints can be adapted to each unit 300.
- the cultivation system 100 comprising the cultivation units 300 thus makes it possible to achieve soil-less cultivation in a controlled manner, by adapting to the needs of the plants.
- [1 1 1] the arrangement in units 300 makes it possible to create, for a shelving 220, one or more culture chambers 204, each culture chamber 204 having its own characteristics, adapted in particular according to the species of plants.
- the number of units 300 is easily adaptable by juxtaposing them, increasing the number of units per row per rack 200 and / or increasing the number of shelving.
- the control system 316 offers increased control of the parameters of the soilless culture, in particular of the characteristics of the atmosphere in the culture chambers 204, but also of the characteristics of the nutrient solution sprayed on the root side of the units. 300.
