The present invention relates to a commercial site for cultivating mushrooms, such as champignon mushrooms, in beds, wherein this site comprises cultivation cells, for allowing to take place the cultivation cycle of the mushrooms which successively comprises one or more preparatory stages and one or more harvesting stages, wherein the commercial site comprises one or more sets of first cultivation cells, provided for allowing the one or more preparatory stages of the cultivation cycle to take place, wherein each set of first cultivation cells comprises at least one growing cultivation cell in which two or more layers of beds are arranged one above the other and wherein the commercial site comprises one or more sets of second cultivation cells, provided in order to allow at least one harvesting stage of the cultivation cycle to take place and in which one layer of beds is arranged or two layers of beds are arranged one above the other, wherein each cultivation is provided for first spending a period of time in one said set of first cultivation cells and then spending a period of time in one said set of second cultivation cells.

The present invention also relates to a method for cultivating edible mushrooms, such as champignon mushrooms, on a commercial site, wherein a cultivation takes place according to a cultivation cycle which successively comprises one or more preparatory stages and one or more harvesting stages, wherein the one or more preparatory stages take place in a said set of first cultivation cells and at least one harvesting stage takes place in a said set of second cultivation cells, wherein the cultivation is moved from the set of first cultivation cells to the set of second cultivation cells.

The cultivation of edible mushrooms, more specifically the cultivation of champignon mushrooms, takes place according to a certain cultivation cycle. Thus, this cultivation cycle comprises one or more preparatory stages and one or more harvesting stages. At most commercial sites, cultivation currently starts with colonized substrate on which a layer of casing soil is placed. Colonized substrate is substrate which has been inoculated with mushroom mycelium, specifically champignon mushroom mycelium (champignon mushroom spawn), and wherein the mycelium has had time to (partly) colonize the substrate. In order to start cultivation, this colonized substrate is placed in a cultivation cell and a layer of casing soil is placed on top of this substrate. This is the start of the preparatory stages which take place before champignon mushrooms can be harvested. Here, the preparatory stages comprise the mycelium growth/mycelium stage and the button stage, respectively. During the mycelium stage, the mycelium grows from the colonized substrate through the casing soil. Thereafter, buttons are formed from the mycelium. This is the button stage. This mycelium stage and button stage together last +/- 14 days. A company may also opt to execute the stages which result in a colonized substrate on the same site. These stages may then also be referred to as preparatory stages.

A harvesting stage is a period in which the champignon mushrooms are harvested. Harvesting is also referred to as 'picking' . Picking may take place manually, but may also be carried out by means of a machine which cuts the champignon mushrooms. Usually, champignon mushrooms destined to be sold fresh are picked by hand, as manual picking ensures good and visible quality. Champignon mushrooms destined for canning and freezing are usually of lower quality and are usually picked by machine.

After the button stage, the harvesting stages start. In the case of the conventional cultivation of champignon mushrooms, these harvesting stages start with a first harvesting stage which is also referred to as the first flush. During the first flush, picking is carried out for a period of 3 to 6 days, after which picking is ceased for a few days. Then the second harvesting stage (second flush) starts. During this second harvesting stage, picking is carried out for on average 2 to 5 days. Possibly there is a third harvesting stage (third flush). A fourth harvesting stage (fourth flush) is also possible. These flushes, which each are a combination of picking, waiting until picking can resume and, if required, treating the cultivation, such as spraying with water, each last +/- 1 week. The yield of the first flush is usually greater than that of the second flush. The yield of the second flush is greater than that of the third flush, etc. Usually, the quality of each flush deteriorates as well. The known methods often use a commercial site comprising one or more sets of first cultivation cells, provided for allowing the one or more preparatory stages of the cultivation cycle to be carried out, and comprising one or more sets of second cultivation cells provided for allowing at least two flushes of the cultivation cycle to be carried out. Each set of first cultivation cells usually comprises only one cultivation cell, namely the growing cultivation cell, wherein the mycelium stage and the button stage take place in this growing cultivation cell. Each set of second cultivation cells usually comprises only one cultivation cell, namely the harvesting cultivation cell, in which at least two flushes of the cultivation cycle take place. In the growing cultivation cell, several layers of beds are stacked on top of each other, and these beds are filled with colonized substrate and casing soil. The mycelium stage and the button stage take place in the two weeks during which the colonized substrate and the casing soil are located in the beds of the growing cultivation cell. Subsequently, the cultivation is moved to a harvesting cultivation cell, for example by means of a pulling device. In the harvesting cultivation cell, the beds are arranged in one layer or two layers. The advantage here is that, by stacking beds in the growing cultivation cell, it is possible to accurately control the climate, resulting in an optimum mycelium stage and button stage. In addition, only a small ground surface area is required. As no picking needs to take place in the growing cultivation cell, the beds can be placed very close together. If the beds in the harvesting cultivation cell are stacked in one layer or two layers, it is readily possible to pick the champignon mushrooms by hand. If desired, the further processing of the picked champignon mushrooms may be (partly) mechanized.

Since the beds in the harvesting cultivation cell are arranged in only one layer or two layers, this means that the required ground surface area of the harvesting cultivation cell is greater than the required ground surface area of the growing cultivation cell. However, in many places ground is scarce and/or expensive. By thus placing the beds in the harvesting cultivation cell in only one layer or two layers in order to simplify and optimize the picking, it is therefore necessary to provide a large surface area for the commercial site.

It is therefore an object of the invention to produce a commercial site for cultivating mushrooms in beds, wherein the required ground surface area is limited, but wherein picking can still proceed smoothly. This object is achieved by providing a commercial site comprising the features as presented in the first paragraph, wherein each set of second cultivation cells comprises at least two harvesting cultivation cells which are located one above the other and are separated from one another by means of a storey floor, and wherein the cultivation is distributed over the said at least two harvesting cultivation cells which are located one above the other. In this case, when moving the cultivation from a said set of first cultivation cells to a said set of second cultivation cells, the cultivation will be distributed over the harvesting cultivation cells which are located one above the other. This means that a part of the cultivation is placed in one harvesting cultivation cell of the said at least two harvesting cultivation cells and that another part of the cultivation is placed in the other harvesting cultivation cell of the said at least two harvesting cultivation cells. One or more harvesting stages then take place in each harvesting cultivation cell. By distributing the cultivation over harvesting cultivation cells which are located one above the other, the required ground surface area is limited and the beds can thus be stacked in one layer or two layers without a significantly larger ground surface area being required. It is possible to place two said harvesting cultivation cells one above the other. However, it is also possible to place three, four, etc. harvesting cultivation cells one above the other, which are separated from one another by a storey floor in order to then distribute the cultivation over three, four, etc. harvesting cultivation cells, respectively. A storey floor refers to a horizontal and structural element which has a supporting and also a separating function. The harvesting cultivation cells of a said set of second cultivation cells which are located one above the other are separated from one another by the storey floor and thus form separate harvesting cultivation cells. The harvesting cultivation cells are thus separated from one another. These harvesting cultivation cells are thus cleanable independently of one another, different climate control is possible here and the spread of diseases between the harvesting cultivation cells can easily be avoided here. In this case, the harvesting cultivation cells may therefore be disinfected separately. There is also no risk here of objects falling out of one harvesting cultivation cell into a harvesting cultivation cell located below and people cannot fall into a harvesting cultivation cell located below. The storey floor supports what is present on this floor, namely the beds in this case. In this case, this storey floor may, for example, be a concrete floor, but may equally be a metal floor or wooden floor. The concrete floor is preferably a virtually fully impermeable concrete floor, so that there is no infiltration of water from above.

If the beds in the growing cultivation cell are, for example, arranged in three layers, each set of second cultivation cells may comprise three harvesting cultivation cells which are arranged one above the other and in which the beds are arranged in one layer, wherein the ground surface area of the growing cultivation cell is then virtually the same as the ground surface area of one said harvesting cultivation cell. If the beds in the growing cultivation cell are, for example, arranged in four layers, each set of second cultivation cells may comprise, for example, two harvesting cultivation cells which are arranged one above the other and in which the beds are arranged in one layer, wherein the ground surface area of a said harvesting cultivation cell is then virtually double the ground surface area of the growing cultivation cell.

Preferably, each set of first cultivation cells comprises only one cultivation cell, namely the growing cultivation cell, with the mycelium stage and the button stage then taking place in this growing cultivation cell. In the said at least two harvesting cultivation cells which are located one above the other, it is then provided to allow preferably two flushes to take place. The rotation between the cultivation cells is then optimal in this case. The cultivation then remains for two weeks in the growing cultivation cell and also for two weeks in the said harvesting cultivation cells, as a result of which the cultivation remains in the growing cultivation cell and the said harvesting cultivation cells for approximately the same amount of time and the rotation between the cultivation cells is optimal. Consequently, after a said cultivation cell has been emptied, this cultivation cell can quickly be filled with a different cultivation of mushrooms again. It is then possible to grow up to 26 cultivations per year for each said set of first cultivation cells and for each said set of second cultivation cells together (52 weeks divided by 2).

In a preferred embodiment, the height of a said growing cultivation cell virtually corresponds to the height occupied by the said harvesting cultivation cells which are located one above the other. Furthermore, the total height occupied by a said set of first cultivation cells then preferably corresponds to the total height occupied by a said set of second cultivation cells. In this way, the building containing the said sets of cultivation cells can be constructed in a uniform manner. Since the beds are arranged in the growing cultivation cell in a number of layers, sufficient height is required here in the growing cultivation cell. In the harvesting cultivation cells, it is only necessary for a person to be able to move forwards and/or for it to be possible to arrange harvesting machines and/or machines for transporting the harvested mushrooms therein. The required height of a harvesting cultivation cell is thus low. Due to the low height, it is possible to control the climate in the harvesting cultivation cell using less energy than in the existing commercial sites. If the beds are arranged in the harvesting cultivation cells in one layer, it is possible here to use machines which are located next to and/or above the beds in order to optimize transportation of the manually picked mushrooms. It is thus possible, for example, to provide a transport system in the champignon mushroom cultivation in which the picked champignon mushrooms can be placed and with the bases being cut off by machine during transportation through this transport system. The beds may also be arranged in the harvesting cultivation cells in two layers. The picking of two layers of beds may also still be performed relatively quickly. It is also possible to opt for the use of a picking machine. If a said set of second cultivation cells comprises 2, 3 or 4 harvesting cultivation cells which are located one above the other, then the height of a said growing cultivation cell preferably virtually corresponds to the height occupied by the 2, 3 or 4 harvesting cultivation cells, respectively, which are located one above the other.

Preferably, the commercial site comprises a pulling hall which is located between a said growing cultivation cell and the at least two harvesting cultivation cells which are located one above the other, wherein the pulling hall comprises closable openings which provide access to the growing cultivation cell and the harvesting cultivation cells, respectively. In this case, the harvesting cultivation cells are thus each accessible from the pulling hall via a different opening. Using an opening which provides access to one said harvesting cultivation cell, it will thus not be possible here to access a different said harvesting cultivation cell, since the harvesting cultivation cells are separated from one another by the storey floor. Using a pulling hall, it is readily possible to move the cultivation from a said set of first cultivation cells to a said set of second cultivation cells. In this pulling hall, it is then possible to arrange pulling devices here in order to simplify and optimize the movement. These pulling devices may, for example, comprise a lift mechanism, such as a scissor lift mechanism, so that the cultivation can be distributed over the said harvesting cultivation cells using this lift mechanism. Furthermore preferably, the opening which provides access to the growing cultivation cell is located at a first side of the pulling hall and the openings which each provide access to a respective harvesting cultivation cell of the at least two harvesting cultivation cells are located at a second side of the pulling hall, wherein this second side of the pulling hall is located opposite the first side of the pulling hall. In this case, the pulling hall then forms a type of passage, at one side of which are located the growing cultivation cells of the sets of the first cultivation cells and at the other side of which are located the harvesting cultivation cells of the sets of the second cultivation cells. In a highly preferred embodiment, the cultivation cycle comprises at least two harvesting stages and the commercial site comprises one or more sets of third cultivation cells, provided in order to allow at least one harvesting stage of the cultivation cycle to take place, wherein the cultivation is provided in order to be moved from a said set of second cultivation cells to a said set of third cultivation cells. The cultivation is therefore provided for remaining for a period of time in a said set of third cultivation cells.

Preferably, the cultivation remains in a said set of first cultivation cells for a period of two weeks. The reason for this is that the preparatory stages, the mycelium stage and the button stage last virtually two weeks. In order to optimize the rotation between the sets of cultivation cells, the cultivation therefore preferably remains in the said harvesting cultivation cells of a said set of second cultivation cells for a period of two weeks. This is due to the fact that, after a said set of cultivation cells has been emptied, it is desirable to quickly fill this said set of cultivation cells with a different cultivation of mushrooms again. This means that it is only possible to carry out two harvesting stages/flushes in the harvesting cultivation cells of a said set of second cultivation cells. After the second flush, the cultivation, namely the substrate with casing soil, is not yet depleted. In principle, it would be possible to carry out a third flush in the harvesting cultivation cells of the said set of second cultivation cells, but then the rotation between the said sets of cultivation cells would no longer be optimal. Also, allowing a third flush to take place would increase the risk of diseases. The reason for this is that the cultivation then remains in one harvesting cultivation cell for a prolonged period of time, giving diseases sufficient time to multiply/develop. If working with 3 flushes, the harvesting cultivation cell would have to be sterilized by steaming after harvesting, before introducing another cultivation into this harvesting cultivation cell. As the yield and the quality of the third flush is low, the additional yield of a third flush does not outweigh the abovementioned drawbacks.

However, by providing one or more sets of third cultivation cells here, it is possible in this case to move the cultivation to a said set of third cultivation cells in order to enable additional flushes, without this compromising the good rotation. As a result, it is possible to optimize the cultivation and maximize the yield per harvest. By harvesting in a said set of second cultivation cells and also harvesting in a said set of third cultivation cells, it is possible to pick for a prolonged period of time here, without this adversely impacting the rotation. If cultivation takes place by substrate cultivation, this means that the yield per amount of colonized substrate can be higher here. Here, an increase in the yield does not mean a loss of time. For example, if using a said set of first cultivation cells comprising only one cultivation cell, namely the growing cultivation cell, this growing cultivation cell may be used for the mycelium stage and the button stage to take place, which together take two weeks, 2 flushes of 1 week each may be carried out in the said at least two harvesting cultivation cells of a said set of second cultivation cells and one or possibly 2 flushes of 1 week each may be carried out in a said set of third cultivation cells. In this case, one or two extra flushes are possible without the rotation of the growing cultivation cell and the said harvesting cultivation cells of a said set of second cultivation cells being compromised. By distributing the harvesting over two sets of cultivation cells, it is possible to harvest for a prolonged period of time without an increase in the risk of diseases and without an increase in the hygiene risks. In addition, the investment in a said set of third cultivation cells may be relatively small, because there are fewer requirements with regard to later harvesting phases. As the yield and quality of the successive harvesting stages always decrease, optimum climate control is of lesser or no importance for a said set of third cultivation cells. As the yield and quality of the at least one harvesting stage in a said set of third cultivation cells is low, it is in addition possible, for example, to opt for picking to be performed only by machine. As a result thereof, the additional labour costs can be limited. The ground surface area may then be made smaller. Obviously, it is also possible to perform picking by hand in a said set of third cultivation cells, if desired. It is possible to increase the yield and profit significantly without having to make excessively large investments, these being the outlay for a said set of third cultivation cells.

If the mushrooms are champignon mushrooms, the harvesting stages preferably correspond to the abovementioned flushes and the cultivation is moved between two flushes. However, it is also possible to move the cultivation during a flush, so that several harvesting stages do not correspond to flushes.

It may optionally be possible to additionally provide a set of fourth cultivation cells, a set of fifth cultivation cells, etc. Furthermore preferably, one layer of beds or two layers of beds are arranged one above the other in a said set of third cultivation cells, and each set of third cultivation cells comprises at least two harvesting cultivation cells which are located one above the other and are separated by means of a storey floor, and wherein the cultivation is distributed over the said at least two harvesting cultivation cells which are located one above the other. The ground surface area of a said set of third cultivation cells may thus be limited. In this case, when moving the cultivation from a said set of second cultivation cells to a said set of third cultivation cells, the cultivation will be distributed over the harvesting cultivation cells of a said set of third cultivation cells which are located one above the other. This means that a part of the cultivation is placed in one harvesting cultivation cell and that another part of the cultivation is placed in the other harvesting cultivation cell. One or more harvesting stages then take place in each harvesting cultivation cell. By distributing the cultivation over harvesting cultivation cells which are located one above the other, the required ground surface area is limited and the beds can thus be stacked in one layer or two layers without a significantly larger ground surface area being required. It is possible to place two said harvesting cultivation cells one above the other. However, it is also possible to place three, four, etc. harvesting cultivation cells one above the other, which are separated by a storey floor. Preferably, two, three, four, five or six layers of beds are arranged one above the other in the growing cultivation cell, and one layer of beds is arranged in a said harvesting cultivation cell of a said set of second cultivation cells. Furthermore preferably, one layer of beds may also be arranged in a said harvesting cultivation cell of a said set of third cultivation cells. The ground surface area of the growing cultivation cell is in this case used in an optimum manner and the climate can be very accurately controlled in the growing cultivation cell. In this case, (manually) picking the mushrooms in the harvesting cultivation cells can take place in an optimum manner.

Preferably, the cultivation uses mats and the commercial site comprises mats. The substrate is then placed on the beds by placing the mats on these beds and placing the substrate on these mats. When moving the cultivation, the mats and the substrate can then be moved together. Each cultivation cell may, however, also comprise one or more mats, in which, when the substrate is moved, the substrate is moved from one set of mats to the other set of mats. In this case, the mats of one set of cultivation cells do not end up in another set of cultivation cells. The mats thus each remain in their cultivation cell, which is separated from the other cultivation cells. This has the advantage that the risk of contamination, diseases, etc. is reduced. The reason for this is that the contaminated mats are not moved along as well. The cultivation on mats may also use, for example, a combination of the two abovementioned options for moving substrate.

In a preferred embodiment, if there are sets of first cultivation cells, sets of second cultivation cells and sets of third cultivation cells, the cultivation is moved from a said set of first cultivation cells to a said set of second cultivation cells and on to a said set of third cultivation cells, wherein these said cultivation cells are preferably virtually in line with one another, in order to thus optimize the movement of the cultivation. Preferably, the said set of second cultivation cells is situated between the said set of first cultivation cells and the said set of third cultivation cells. Furthermore preferably, there is a certain intermediate space between these successive sets of cultivation cells so that the movement of the cultivation between the said cultivation cells can proceed smoothly. For example, if the cultivation is a substrate cultivation on mats, it is possible to use devices, for example pulling devices, to move the substrate, in which case these devices are largely arranged in a said intermediate space at least during the movement of the cultivation. This said intermediate space may, for example, be a pulling hall.

The amount of time which the cultivation spends in a said set of first cultivation cells preferably virtually corresponds to the amount of time which the cultivation spends in a said set of second cultivation cells. The amount of time which the cultivation spends in a said set of third cultivation cells is then preferably virtually equal to or less than the amount of time which the cultivation spends in a said set of second cultivation cells. Furthermore preferably, the amount of time which the cultivation spends in each said set of cultivation cells is preferably virtually identical. Here, an optimum rotation has then been achieved, so that a cultivation can be present in each cultivation cell during virtually the entire year. Here, the capacity of the cultivation cells is used to an optimum extent.

Furthermore preferably, the amount of time which the cultivation spends in a said set of first cultivation cells and the amount of time which the cultivation spends in a said set of second cultivation cells is virtually 2 weeks. This means that, for cultivating champignon mushrooms by means of colonized substrate, the preparatory stages, being the mycelium stage and the button stage, take place in a said set of first cultivation cells. The reason for this is that these preparatory stages together last +/- 14 days. This also means that 2 harvesting stages, being 2 flushes, can take place in a said set of second cultivation cells. It is also possible for 1 or 2 harvesting stages, being 1 or 2 flushes, to take place in the said set of third cultivation cells without compromising the optimum rotation. Here, the capacity of the substrate is used to an optimum extent. This object is also achieved by providing a method for cultivating edible mushrooms, such as champignon mushrooms, on a commercial site as presented above, wherein a cultivation takes place according to a cultivation cycle which successively comprises one or more preparatory stages and one or more harvesting stages, wherein the one or more preparatory stages take place in a said set of first cultivation cells and at least one harvesting stage takes place in a said set of second cultivation cells, wherein the cultivation is moved from the set of first cultivation cells to the set of second cultivation cells, wherein during the transfer of the cultivation to the set of second cultivation cells, a part of the cultivation is placed into one harvesting cultivation cell of the at least two harvesting cultivation cells of the set of second cultivation cells and a part of the cultivation is placed into the other harvesting cultivation cell of the set of second cultivation cells, so that the cultivation is distributed over the at least two harvesting cultivation cells. Since, as illustrated above, the ground surface area of a said set of second cultivation cells can be limited here, this method can therefore be carried out on a limited ground surface area.

Preferably, the cultivation is moved from the growing cultivation cell to and distributed over the at least two harvesting cultivation cells of a said set of second cultivation cells with the aid of a pulling device, wherein the pulling device comprises a lift mechanism in order to thus be able to pull the cultivation into both of the at least two harvesting cultivation cells. The movement of the cultivation may be quick and simple here.

This method preferably takes place on a commercial site comprising a pulling hall which is located between a said growing cultivation cell and the at least two harvesting cultivation cells which are located one above the other, wherein the pulling hall comprises closable openings which provide access to the growing cultivation cell and the harvesting cultivation cells, respectively, wherein the pulling device is arranged in the pulling hall. Preferably, the cultivation takes place on substrate, and when moving the cultivation from a said set of first cultivation cells to a said set of second cultivation cells, the substrate is also moved. In the method of cultivation on substrate in beds, it is readily possible to move the substrate. In a preferred embodiment, the substrate is placed in the beds.

Furthermore preferably, the cultivation uses mats, and the substrate is placed on these mats. Also preferably, the mushrooms are picked manually in the one or more harvesting stages which take place in a said set of second cultivation cells.

In a highly preferred embodiment, the commercial site comprises one or more sets of third cultivation cells, wherein the cultivation is moved from a said set of second cultivation cells to a said set of the third cultivation cells. It is possible to pick manually in the said set of third cultivation cells, but it is also possible to opt for the use of a picking machine. If a picking machine is used, it is possible to arrange the beds in two or more layers in the said set of third cultivation cells. The present invention will now be explained in more detail by means of the following detailed description of a preferred embodiment of a method and commercial site according to the present invention. The sole aim of this description is to give illustrative examples and to indicate further advantages and features, and can thus by no means be interpreted as a limitation of the area of application of the invention or of the patent rights defined in the claims. Reference numerals are used in this detailed description to refer to the attached drawings, in which:

-Figure 1 shows a diagrammatic representation of a cross section through the commercial site at the location of cultivation cells over which one cultivation is distributed;

-Figure 2 shows a diagrammatic representation of a top view of the commercial site at the location of the cultivation cells illustrated in Figure 1. This commercial site comprises several sets of first cultivation cells, as many sets of second cultivation cells and as many sets of third cultivation cells. Each set of first cultivation cells comprises only one cultivation cell, namely a growing cultivation cell (2). Each set of second cultivation cells comprises two cultivation cells, namely two harvesting cultivation cells (3) which are located one above the other and which are separated from one another by means of a storey floor (4). Each set of third cultivation cells comprises only one cultivation cell, namely a harvesting cultivation cell (6).

The commercial site further comprises a first pulling hall (5) which extends between the growing cultivation cells (2) and the said harvesting cultivation cells (3) of the sets of second cultivation cells. This first pulling hall (5) comprises closable openings which provide access to the growing cultivation cells (2) and the harvesting cultivation cells (3), respectively. The openings which provide access to the growing cultivation cells (2) are located at a first side of the first pulling hall (5) and the openings which each provide access to one of the said harvesting cultivation cells (3) are located at a second side of the first pulling hall (5), wherein this second side of the first pulling hall (5) is located opposite the first side of the first pulling hall (5).

The commercial site also comprises a second pulling hall (7) which extends between the harvesting cultivation cells (6) of the sets of third cultivation cells and the said harvesting cultivation cells (3) of the sets of second cultivation cells. This second pulling hall (7) also comprises closable openings which provide access to the harvesting cultivation cells (3, 6), respectively. The openings which provide access to the harvesting cultivation cells (3) of the sets of second cultivation cells are located at a first side of the second pulling hall (7) and the openings which each provide access to the harvesting cultivation cells (6) of the sets of third cultivation cells are located at a second side of the second pulling hall (7), wherein this second side of the second pulling hall (7) is located opposite the first side of the second pulling hall (7).

The height of each growing cultivation cell (2) virtually corresponds to the height of the two harvesting cultivation cells (3) of a said set of second cultivation cells. The height of each growing cultivation cell (2) virtually corresponds to the height of each harvesting cultivation cell (6) of a said set of third cultivation cells.

In each growing cultivation cell (2), 4 layers of beds (1) are stacked one above the other. In each harvesting cultivation cell (3) of a said set of second cultivation cells, the beds (1) are in one layer and in each harvesting cultivation cell (6) of a said set of third cultivation cells the beds (1) are once again in four layers. As a result, the ground surface area of the sets of second cultivation cells is virtually double the ground surface area of the sets of first cultivation cells or of the sets of the third cultivation cells. This can clearly be seen in the figures.

The method for cultivating champignon mushrooms on this commercial site proceeds as follows:

The cultivation comprises two preparatory stages and four harvesting stages, being flushes. The cultivation takes place on substrates and mats, wherein the mats are placed on the beds (1) and the substrate is placed on these mats during the placement of the mats on the beds (1).

The two preparatory stages comprise the mycelium stage and the button stage, and these preparatory stages together last +/- 14 days. These preparatory stages take place in a said growing cultivation cell (2). After the button stage is complete, the harvesting stages start. Before being able to harvest, the cultivation is moved from the growing cultivation cell (2) to and distributed over the harvesting cultivation cells (3) of a said set of second cultivation cells. In this case, the cultivation is moved using a pulling device which is arranged in the first pulling hall (5), specifically by pulling the substrate from the mats and placing it back on other mats, wherein these other mats are placed on the beds (1) of the said harvesting cultivation cells (3) of the said set of second cultivation cells.

The cultivation remains for two weeks in this said set of second cultivation cells and two flushes are carried out during these two weeks. After these two flushes, the cultivation is pulled to the harvesting cultivation cell (6) of a said set of third cultivation cells using a pulling device which is arranged in the second pulling hall (7). In the said set of third cultivation cells, the cultivation remains for two weeks and two flushes take place. The rotation between the sets of cultivation cells is thus optimal in this case.
