- the box 6 comprises four pipes 32, two per compartment.
- the number of pipes 32 is not limiting.
- the pipes 32 travel through the culture chamber and are equipped with spray nozzles 32.1. With these nozzles 32.1, the fluid flowing in the pipes 32, that is to say the solution loaded with nutrients and minerals, is sprayed in the form of fog inside the box.
- the pipes 32 are of the same section and of the same length. Flowing fluid in the tube 24 is therefore distributed equitably between the four pipes 32.
- the pipes 32 are immobilized inside the box 6. For example, they can be fixed to the inner walls of the box 6.
- One or more programmers may for example be used to control the irrigation phases.
- a programmer may be dedicated to each compartment and / or to each culture support 60.
- a single programmer may alternatively be used for all the compartments.
- the culture box 6 comprises several culture supports 60, which are each located on one face of the box 6.
- the two opposite faces 6a and 6b of the box 6 each comprise at least one culture support 60, preferably two culture supports 60 arranged side by side.
- the fact that the culture box 6 is rotating allows to have the culture media 60 on two sides of the box, in particular on two opposite faces of the box, because the vegetation is in turn exposed to the sun's rays. The yield is improved.
- Each culture support 60 is removable. This makes it easy to harvest the plants because it suffices to simply withdraw the culture support 60 from the can 6.
- Each culture support 60 comprises a plate and one or more containers each for receiving a substrate for the plants.
- each plate is placed on at least two support pieces at right angles, that is to say in the shape of an L, of which only one of them is visible in FIG.

- Each container is a pot 60.1 or a box 60.2.
- the type of container is chosen according to the type of vegetation or planting.
- each container is removably attached to the plate of the culture support 60.
- the plate then defines openings for the positioning of the container or containers (pots, basket, box ).
- Different systems are possible for fixing the containers on the plate. In particular, it is possible to use screws, elastic clips, extensible fasteners, locking means in the form of a rotating tongue, etc. These systems make it possible to prevent the plants from falling when they are find, during the rotation of the culture box 6, upside down. These are the plants arranged on the side of the face 6b in the configuration of Figure 4.
- Each of the containers comprises a device for holding the substrate inside the container, that is to say to prevent the substrate from leaving the container when the plants are upside down.

- This device is optional depending on the type of substrate used (for example: rockwool, foam).
- Each container 60.1 or 60.2 has a perforated bottom to allow the roots R of the plants to cross the bottom of the container and penetrate inside the culture dish 6.
- the roots R then grow in the open air and are sprayed with a mist of nutrient solution by the nozzles 32.1 of the pipes 32.
- This type of culture has the advantage of using relatively little water compared to the conventional earth culture method.
- the culture dish 6 comprises separation plates 66 for separating the roots of the plants from the top with the roots of the lower plants, that is to say the roots of the plants arranged on the side of the face 6a with the roots plants arranged on the side of the face 6b.
- the separating plates 66 are fixed at mid-height inside the box 6, in particular in the example on the frame 62. They divide each compartment of the culture chamber in two.
- the partition plates 66 are removable. They can be made of woven or non-woven.
- each separator plate 66 may be a root mat, which is a horticultural felt web that is hydrophilic and rot-proof.

- the "used" liquid contained in the recuperator 8 is reinjected into the irrigation circuit of the culture box, and in particular into the supply pipe 16.
- a conduit 13 connects the recuperator 8 to the supply pipe 16.
- a suction system 19 is then used to suck the liquid contained in the recuperator 8 and reinject it into the pipe 16.
- the suction system 19 is a water pump, but it may also be, alternatively, a booster, with or without bladder, or any other suction system.
- a programmer (not shown) can be used to control the suction system 19.
- the type of circuit (open or closed) is selected according to the duration of the growth cycle of the plants, that is to say according to the nature of the plants.
- the open circuit is rather adapted to plants whose cycle of growth is long, whereas the closed circuit is rather adapted to plants whose growth cycle is short.
- the pumping of the liquid contained in the recuperator 8 is cleverly facilitated by the presence of a pumping pit 12.
- the pit 12 is an integral part of the recuperator 8. It can, however, be dissociated therefrom.
- An evacuation device (not shown) makes it possible to evacuate the liquid contained in the tank 8 towards the pit 12 in the case of a closed circuit or outside the system 2 in the case of an open circuit.
- This device can be of the passive type, as an overflow, or on the contrary of the active type, as a self-priming siphon. It is also possible to combine the two types of device (active and passive).
- a regulation system is further provided for regulating the level of liquid contained inside the recuperator 8.
- This control system comprises a conduit 20 for conveying liquid, preferably using the effect of gravity, for example the In the example, the regulation is carried out by means of a float (not shown), but any other device is conceivable.
- the system 2 also comprises light reflectors 10. More specifically, two reflector panels 10 are fixed on either side of the tray 8. The reflector panels 10 are orientable. Their orientation depends on the type of source luminous (natural or artificial) and the desired effect (concentration or dispersion of light rays). The reflector panels 10 can also help to collect the liquid discharged out of the box 6.

- the box 6 or 6 comprises a mechanism for selectively ventilating the culture chamber as a function of the humidity level and / or the temperature of the air inside the box.
- This type of mechanism is particularly advantageous for the culture of seeds. Aeration can for example be done by one or more openings in the partitions 63 or in the faces 6c and / or 6d of the box.
- at least one container is covered with an individual cap, which provides a greenhouse effect.
- At least one container is equipped with a guide for channeling the growth of roots R of the plant.
- This type of container is particularly adapted to accommodate plants with high root growth.
- the guide extends from the bottom of the container in the direction of root growth.
