This invention relates to a method and a system for vertical cultivation of plants in plant pots in a modular configuration. Also, the invention relates to a device for vertical cultivation of plants in plant pots in a modular configuration suitable for growing ornamental plants and food crops as well as to a special plant pot to be used in the device , the method, and the system according to the invention.

Many modular systems and methods for cultivating pot plants are known. These systems, being equipped with irrigation and illuminating systems, are embodied in horizontal as well as vertical configurations. From Chinese patent CN103250588 (A) one knows a method for cultivating plants comprising heating up plants in plant pots, illuminating them, and sprinkling. Parameters of heating up, illuminating, and sprinkling, along with the air humidity in the proximity of the cultivated plants are controlled, and the method uses a smart plant pot that was claimed in that patent to be protected also as a device. However, in the case of a large number of pots with plants such cultivation becomes complicated since every plant pot is treated individually. The number of sensors and illuminating and sprinkling devices also is significant increasing the risk of failure. Moreover, the wetting system and illumination wiring system spread out.

Chinese utility pattern CN2663591 (Y) describes a multilevel vertical wall module for cultivating flowers, where every level of the module comprises a reservoir with water and a duct delivering the water to every plant pot of the given level.

Chinese utility pattern CN203762001 (U) discloses a vertical container for plants manufactured in a modular manner from ABS plastic, provided with water permeable ports, the ports being dedicated also for ventilating the plants. Two ducts with water, placed in the upper and lower level of the module, serve for irrigation .

Also, from Polish Patent Application P346362 one knows a plant pot comprising a first space delimited by a first vertical wall and a second space delimited by a second vertical wall and a bottom wall. A porous plate separates the first and second spaces from each other. A third space delimited by a third vertical wall and the bottom wall encloses the second space. The second space serves for accommodating a moisture keeping material therein, becoming watered but being air permeable at the same time.

Also, from Polish Patent Application P.314272 a device is known for automated irrigation, particularly irrigation of pots with flowers. The device is composed from a programming apparatus and a distributing apparatus that has electromagnetic valves built into individual irrigation systems. The valves are connected electrically, via relays, to the programming apparatus in which the electronic circuit consists of a control unit linked with a control desk and a memory of switch on/off cycles as well as with a display of irrigation time and working time of individual irrigation systems.

The aim of the present invention is to provide an alternative method for cultivation of pot plants in a modular arrangement and vertical configuration that would be reliable, simple in operation, fitted to the needs of cultivated plants and simultaneously flexible such that it can be used for cultivating different ornamental plants and food crops.

Moreover, the aim of the invention is to provide a device for vertical cultivation of plants in pots, that guarantees good conditions for cultivating plants using the method according to the invention and that uses plant pots designed especially for this device as well as general-purpose pots which are merely adapted for the needs of cultivation within this device.

Moreover, the aim of the invention is to provide a special plant pot adapted in particular for the device according to the invention and making it possible to obtain the best embodiment of the method according to the present invention.

Also, the aim of the invention is to provide such a system of cultivating plants that would make it possible to expose cultivated plants in different, convenient configurations and that would be flexible enough to make it possible to adapt it to existing space and room conditions. The method according to the invention is characterized in that irrigation of plants is performed gravitationally with the use of a band of transmission made from water permeable, unwoven fabric, and comprises steps of delivering water to the highest level of the plants such that the water freely enters a pot via a irrigating channel. Next, the water penetrates the plant pot, moistening also the unwoven fabric portion of the plant pot, the excess water flowing to an overflow channel below the plant pot. The water is directed to the irrigating channel of the lower plant level and irrigates subsequent levels of the plants located below in a similar manner. From the lowest level of the plants water enters a reservoir, from which it is again pumped by a pump, after filtering, to the highest level of the plants. Water from said reservoir is delivered also to sprinklers. The water level in the reservoir is controlled by means of a lower water level sensor and an upper water level sensor that signal, on a control panel, a deficiency or a surplus of water in the reservoir, correspondingly. The ducts delivering water are flushed periodically in a closed cycle. Moreover, the plants are illuminated periodically using a source of light of a spectrum fitted for the needs of the plants and their photosynthetic and energetic efficiency, with a possibility of setting the angle of incidence of the light rays onto the leaves of the cultivated plants. The irrigating channel delivers water to the plant pot from above whereas the unwoven-fabric band of transmission of every plant pot passes the water downwardly - from the irrigating channel to the overflow channel. Optionally, the water may be delivered to the plant pot from the bottom up, from an overflow reservoir by means of a water-absorbing band connected with the bottom of the plant pot, which soaks with water and moistens the unwoven-f bric band of transmission by means of capillary action, passing water from the bottom up and irrigating the root system of the plants from below.

The modular system of vertical cultivation of plants in plant pots is characterized in that the vertical casing comprises at least one chamber in which a special plant pot is placed such that an irrigating channel is located at the top and an overflow channel is located at the bottom. The longitudinal axis of the plant pot is inclined relative to the end face of the vertical casing at an angle from 8° to 25°, preferably 13°. After placing within the chamber, the bottom wall of the plant pot is facing toward an aerating channel located in the bottom of the chamber and open to the outside. The casing is mounted to a frame-like support structure that is adapted to place illuminating means and means for extra sprinkling the plants on at least one of its sides.

The following description presents embodiments of a method and system for vertical cultivation of plants in plant pots in a modular arrangement as well as embodiments of a device for vertical cultivation of plants in plant pots in a modular arrangement, suitable for cultivation of ornamental plants and food crops, and also embodiments of a special plant pot to be used with the device, the method, and the system according to the invention. However, it should be emphasized that the described embodiments are not intended to limit the scope of protection but merely illustrate one out of many possible applications of the present invention. The present invention is applicable everywhere where a cultivation of plants is needed, making it possible to freely arrange green spaces of various scales, indoors as well as outdoors.

Fig. 1 shows a device for vertical cultivation of plants in special plant pots according to the invention, the device being shown in a first embodiment. The device of a width of 935 mm and a height of 739 mm has a vertical casing 1 that constitutes a module for a seat-like cultivation of plants. The casing 1 has a depth of 130 mm and is mounted to a frame la. The upper side and two side arms of the casing la have a width of 80 mm, whereas the bottom side has a width of 182 mm. The casing 1 comprises fifteen chambers 2 arranged symmetrically in three rows and five columns, in which special plant pots 3 are placed. All the chambers 2 are frusto-conical and have a height of 110 mm and are facing to the same side. The bottom of every chamber 2 has a diameter of 100 mm. A ventilating zone with a ventilating opening is located at the bottom of the chamber 2. At the root of the chamber, the chamber 2 has a diameter of 120 mm. An irrigating channel 4 is located above every chamber 2 and an overflow channel 5 is located below the chamber 2. The device is equipped with a closed cycle system for irrigating plants.

Water is taken from a reservoir 7 that is mounted by shape coupling to the lower part of the frame la. Also, this is the destination of excess water after the whole irrigation cycle. Water is refilled manually. The reservoir 7 contains 10.7 liters of water. The amount of water being present in the irrigation cycle is monitored and exceeding the minimum or maximum water level is signaled on a control panel 8 that is located on the front wall of the casing 1, close to the vertical side of the frame la, as shown in Fig. 2. The reservoir 7 is equipped with a lower water level sensor and an upper water level sensor. The upper water level sensor signals the minimum level of water in the system. When the water level exceeds the minimum acceptable threshold value, a diode-based signaling device 9 is switched on alerting that water in the reservoir should be refilled. Similarly, during refilling water, the second sensor, placed at the upper edge of the water reservoir above the lower sensor, generates an electric signal triggering the diode-based signaling device 9. The diode device 9 lights then in a pulsatory manner informing that the water level, in the reservoir has been exceeded. Additionally, on the panel 8 shown in an enlarged view in Fig. 4, there is a switch 10 of the irrigation, sprinkling, and illumination system as well as a potentiometer 11 for controlling the irrigation efficiency. The water circulation is obtained by means of a pump 12 controlled electronically. The nozzle of the water intake is equipped with a filter (not shown) with known water permeability parameters, removing most of contaminations. Electrical subassemblies are supplied from a DC power supply in a form of DC battery assembly 13. The power supply 13 and the pump 12 are located on the vertical side of the frame la and are covered by a cover 14. Irrigation is performed cyclically, keeping the desired humidity level of the rootstock and flushing all the piping delivering water to the plants. This ensures a longterm patency of the system working in a closed cycle, without the need of servicing, thanks to eliminating the risk of the growth of biological cultures and building-up scale inside the water ducts. Water is dispensed onto the transmission band of unwoven fabric 3e via the irrigating channel 4. In this case a water-permeability occurs perpendicular to the cross-sectional plane of the plant pot 3, that is illustrated in the following in Figs. 26 and 27. Excess water is transferred by the water-permeability in the cross-sectional plane of the plant pot 3 and transferred to a plant pot located below via the overflow channel 5. The task of the transmission unwoven fabric 3e is both to release water to the soil substrate and plant roots and also to drain the soil substrate to prevent accumulation of too much water within the substrate. In order to ensure the optimal vegetation conditions, the system is equipped with an extra illuminating-sprinkling system hidden in a lateral arm of the vertical frame la. During the operation of the system with illumination and sprinkling, a drive system, controlled electronically, opens the cover 14 for a preset time needed to illuminate and sprinkle the plants properly. The source of light is selected considering the spectrum contents as well as the photosynthetic and energetic efficiency. Sprinkling is performed by a set of atomizers supplied with water from the irrigation system. The whole device is equipped with catches for hanging on a wall. Figs. 5, 6, and 7 show an arrangement of plant pots 3 in the device. Longitudinal axes of the plant pots are inclined relative to the end face of the casing 1 at an angle of 13°. After placing a plant pot 3 in a chamber 2, this being best illustrated in Fig. 7, the bottom 3d of the plant pot 3 is facing towards an outwardly open aerating channel 6 located in the bottom of the chamber 2. The irrigating channel 4 is located directly at a height of the lower edge of a tight sheath 3b of the plant pot 3. Water enters the plant pot gravitationally and moistens the root system of the plant by means of unwoven fabrics located within the plant pot 3. Excess water is removed, also gravitationally, by means of the overflow channel 5 located in the neighborhood of the edge 3a and the lower part 3c of the plant pot 3.

A device for vertical cultivation of plants in plant pots is not limited exclusively to the shown embodiment. For example, Fig. 3 shows a rear perspective view of another embodiment of a device according to the invention. In this embodiment aerating channels 6 are located next to profiled chambers 2 and also prevent anaerobic processes within a watered plant pot and allow for cleaning the air through the plant pot. In another embodiment, in order to signal exceeding the lower or upper water level in the reservoir, separate diode signaling devices 9 are used having different colors or pulsing with a characteristic frequency. Moreover, water for the irrigation may be optionally taken from an external source, and, after the irrigation cycle, discharged to the sewer system. Moreover, water for the irrigation may be, optionally, taken from an external source and, after the irrigation cycle, may be discharged to the sewer system.

Usually, an open cycle is used in devices of larger areas. Furthermore, the number and arrangement of chambers 2 are not limited to the embodiment illustrated previously in Fig. 8, where a device is shown for vertical cultivation of plants with a vertical module having fifteen columns arranged in three rows and five columns. For example, Fig. 9 shows a device for vertical cultivation of plants having six chambers arranged in three rows and two columns. Fig. 10 shows a casing having sixteen chambers 2 arranged symmetrically in four rows and four columns, and Fig. 11 shows a device with two sets, each of them having forty-two chambers 2 arranged in seven rows and six columns on each side of the device. Figs. 11, 12, and 13 show a freestanding embodiment of the device. As seen best in Fig. 13, plants may be placed in chambers of the casing on both sides of the casing. Figs. 14-19 show flexible variants of the casing. Then, it is possible to flex the columns to expose cultivated plants in the most effective way. However, the device according to the invention is not limited to the shown embodiments. Figs. 20 to 23 show in turn an embodiment of the device with two movable frames lb and lc. The axes of revolution of the frames are parallel to the longer arm la of the casing and are placed at the half of the width of the casing 1. Then, it is possible to move the illuminating and irrigation means placed on the frames lb, lc. Figs. 24 and 25 show an embodiment of the device with the casing having sixteen chambers arranged in four rows and four columns, water being delivered to the plant pots 3 placed in the chambers 2 from below by means of capillary action. As is shown best in Fig. 7b in connection with Fig. 25, water flows down gravitationally to the reservoir 5b via a channel 5a. Water is taken therefrom by a band 3i to a special plant pot. A special plant pot, most suitable for this embodiment, is shown in Fig. 28 and 29. Fig. 28 shows an embodiment of a plant pot 3 delivering water to the cultivated plant from below. The plant pot is lined with transmission unwoven fabric 3e in the lower part, defining, also, the bottom with the band 3i protruding downwardly.

Figs. 26 and 27 show, in turn, a special plant pot 3 that makes it possible do deliver water to the cultivated plant from above. The plant pot 3 is frusto-conical and has a height of 125 mm and has an upper edge 3a, a tight sheath 3b, and a lower part 3c. The lower base of the cone of the plant pot 3 has a diameter of 95 mm, whereas the upper diameter of the cone of the plant pot 3 is 125 mm. In the tight sheath 3b there is an irrigating channel 4 and an oppositely placed overflow channel 5. The irrigating channel 4 makes it possible to deliver water to the plant pot 3 in equal doses. A water-permeable transmission unwoven fabric 3e and a water-storing unwoven fabric 3f adhere to the tight sheath 3b from inside. The use of the storing unwoven fabric 3f in the special plant pot 3 allows for optimal irrigation and aerating the rootstocks of the plants in the special plant pots 3. The upper edge 3a of the plant pot 3 is made from ornamental rubber, whereas the tight sheath 3b and the lower part 3c of the plant pot 3 is made from PVC . The unwoven fabric 3e filling the internal tight sheath 3b is a mixture of cut polypropylene and polystyrene fibers, and the unwoven fabric filling the lower part 3c and the bottom 3d is made from polypropylene fibers. The storing unwoven fabric 3f is arranged such that, on one side, it partially overlaps the irrigating channel 4, and, on the other side, overlaps the overflow channel 5. The transmission unwoven fabric 3e adheres to the lower part 3c of the plant pot. The use of unwoven fabrics 3e and 3f in the plant pots 3 results in passing water in a plane, storing water, and ability of capillary ascent that is adapted for selected groups of plants and the ways of their cultivation. Unwoven fabrics 3e and 3f occupy totally 30% of the surface area of the plant pot 3 and allow for distributing water to the whole plant pot 3 preventing over-watering, strangling the roots or over-drying them. The lower part 3c is closed by the bottom 3d made from the transmission unwoven fabric 3e. The structure of the lower part 3c closed by the bottom 3d made from the unwoven fabric 3e allows for air penetration to the lower part of the special plant pot 3 and its ventilation.

Such a cover for the rootstock prevents, mechanically, falling out of the soil substrate from the special plant pot 3 and prevents escaping spores of bacteria and fungi growing in the soil environment.

In the method for vertical cultivation of plants in special plant pots according to the invention the irrigation of plants is performed by a water band of transmission. In a first embodiment of the method according to the invention water is first delivered to the highest level of the plants by means of a pump, over every plant pot 3 with a plant. Next, the water enters the plant pot 3 freely via the irrigating channel 4, penetrating the plant pot and moistening its part of the unwoven fabric 3e and 3f. The excess water is passed to the overflow channel 5 below the plant pot and travels gravitationally to the irrigating channel 4 of the lower level of the plants, thus irrigating next levels of the plants located below. From the last, the lowest level of the plants the water gravitationally enters the water reservoir 7, from where, after filtering, it is pumped again by the pump 12 to the highest level of the plants, to the irrigating channels of the highest plants.

In a second embodiment of the method according to the invention, water is first delivered to the highest level of the plants by means of a pump, below every plant pot 3 with a plant, this being best shown in Fig. 25. Next, as shown in Fig. 29, the water enters the plant pot 3 by means of capillary action via the irrigating band 3i, penetrating the plant pot and moistening its part of the unwoven fabric 3e and 3f. Simultaneously, the water passes from below of the plant pot 3 of the higher row to the space below the plant pot 3 of a lower row. In this row the water enters the plant pots 3 in a similar way via the irrigating bands 3i. From the last, the lowest level of the plants the water gravitationally enters the water reservoir 7, from where, after filtering, it is pumped again by the pump 12 to the highest level of the plants, to the irrigating bands of the highest plants.

Also, water is delivered to sprinklers from the reservoir 7. The irrigating and sprinkling jets are controlled and the absence or a surplus of water in the reservoir 7 is signaled on the control panel 8. The water-delivering ducts are flushed cyclically in a closed cycle when the device is operated in the service mode. The illumination of the plants is performed cyclically using a source of light with the spectrum fitted for the needs of the plants and their photosynthetic and energetic efficiency.
