Description

VERTICAL GROWING SYSTEM AND USE OF SUCH SYSTEM FOR PLANT GROWING Technical field The present invention refers to a growing system for plant growing and the use of such growing system for plant growing.

Technical background Domestic plant growing has become more and more popular to grow e.g. your own herbs and salad. One underlying reason is the overall interest in a more sustainable society, a healthier lifestyle and also cooking. Another reason is that more and more people live in small apartments without access to their own garden or balcony. Also, the available living space is limited, which affects the possibility to use ordinary pots and stands for indoor growing. In an attempt to meet this, many solutions are provided that allows vertical growing. Examples are given in US 4 231 189, GB 2 147484 and US 4454 684.

Vertical growing does however imply problems when it comes to the provision of an even irrigation as seen along the vertical direction. Due to gravity, the supplied water strives downwardly with the risk of upper sections being left dry while lower sections are left with a too high degree of humidity. There is also a need to supply a device that has an appealing design. Also, the growing system should be easy to assembly and clean since the use of soil, water and fertilizers often cause deposits.

Summary One object of the present invention is to provide a growing system that may be used for domestic use in e.g. a window sill for growing plants, seedlings or even seeds.

The growing system should include an irrigation system that allows vertical growing and which irrigation system is easy operable and adjustable.

The growing system should be easy to assemble and disassemble to allow cleaning.

The growing system should be applicable no matter if it is used for traditional growing using soil or hydroponic growing.

As yet another object, the growing system should be decorative.

These and other objects are solved by a growing system for plant growing, comprising at least a first and a second growing module configured to be arranged one on top of the other as seen in a vertical direction, each growing module comprising: an inner circumferential wall and an outer circumferential wall having a longitudinal extension as seen in the vertical direction, the inner circumferential wall defining an inner space having an open upper end and an open lower end, whereby the inner spaces of each growing module together form a combined inner space configured to contain a growing medium; and the inner circumferential wall together with the outer circumferential wall defining an irrigation space encircling the inner space; and a pipe forming a through-going channel extending from the inner circumferential wall to the outer circumferential wall and forming part of a growing vessel, whereby the inner space is configured to communicate with the ambience via said through-going channel; wherein an outer surface of the pipe comprises an upper fluid receiving compartment having a bottom wall provided with an irrigation hole allowing a fluid contained in the upper fluid receiving compartment to flow into the through-going channel of the pipe, whereby a plant to be received in the throughgoing channel is irrigated.

In the context of the application the term growing medium should be interpreted as including soil, peat or a fibrous organic or synthetic material.

Thus a modularized growing system for vertical growing is provided. The growing modules are to be arranged one on top of the other to form a column with different growing levels. Each growing module comprises a through-going channel forming part of a growing vessel in which a growing medium together with a plant, a seedling or a seed is to be contained.

Growing medium to be contained in the growing vessel will be in contact with a larger volume of growing medium to be contained in the combined inner space. Since the growing medium is not restricted to traditional organic material such as soil or peat the growing system is applicable to hydroponic growing as well.

Each growing module comprises an integrated irrigation system where each pipe and hence each growing vessel comprises a dedicated fluid receiving compartment. Accordingly, each growing vessel and hence each plant will have its own dedicated irrigation no matter where in a column of growing modules the individual growing module is positioned. It is to be understood that each growing module may comprise more than one through-going channel.

The irrigation space may further comprise a lower fluid receiving compartment, wherein the upper fluid receiving compartment comprises an overflow outlet allowing any surplus fluid to flow from the upper fluid receiving compartment to the lower fluid receiving compartment. Accordingly, there is no accumulation of any larger volumes of fluid that may cause a too high degree of humidity of the growing medium.

The lower fluid receiving compartment may comprise a draining hole allowing fluid contained in the lower fluid receiving compartment to flow into an upper irrigation fluid compartment of a second growing module to be attached to a lower end of the first growing module to thereby be arranged below the first growing module.

The interaction between the upper and lower fluid receiving compartments of the first and second growing modules may be seen as a pyramid of champagne glasses where the surplus contents of the top glass, i.e. the upper fluid receiving compartment in the upper most first growing module will be allowed to flow down to the lower fluid receiving compartment in the same growing module and then further down via the draining hole to the upper fluid receiving compartment in the second growing module arranged below the first growing module. Thereby, an effective irrigation system is provided throughout the full vertical height of the column of growing modules.

The at least two growing modules in a condition when arranged to each other, one on top of the other, may be angularly displaced in view of each other as seen around a longitudinal vertical axis, whereby a lower fluid receiving compartment of a first growing module communicates with an upper fluid receiving compartment of a second growing module via the draining hole.

The angularly displaced growing modules will ensure that surplus fluid from one growing module is efficiently and correctly directed to the fluid compartment of the subsequent growing module. Also, the fluid that is received in the lower fluid receiving compartment will leave the same in the vertical direction via the draining hole in the bottom wall of the lower fluid receiving compartment and flow into an upper fluid receiving compartment of the second growing module which is attached below the first growing module. By the fluid being guided in the circumferential direction in the irrigation space in each growing module and by the plurality of growing modules being angularly displaced in view of each other around the longitudinal vertical axis, the fluid will be step wise guided in the vertical direction to the different inserts in the guiding modules throughout the column. The same principle will apply until the fluid has passed all growing modules.

The growing system may further comprise a tank configured to be arranged to an upper end of the first growing module, and wherein said tank comprises a draining hole configured to allow fluid contained in the tank to flow into the upper fluid receiving compartment of the first growing module.

The tank may have a volume large enough to hold a number of days’ fluid consumption to thereby reduce the maintenance. The tank is preferably made from a transparent material to allow easy, visual information about the remaining fluid level.

The draining hole in the tank may comprise a check valve configured to allow setting of the fluid flow from the tank to the upper fluid receiving compartment of the first growing module. Thereby the user may control the flow of fluid from the tank to the irrigation space. The check valve may, depending on the desired degree of humidity, be set from a fully closed-off flow, to dripping, or to a continuous flow.

The growing system may further comprise a plant receiving insert configured to be attached to the pipe of the growing module, wherein said plant receiving insert comprises a through-going going channel allowing the inner space to communicate with the ambience via said through-going channel. The plant receiving insert forms part of the growing vessel and is configured to be filled with a growing medium such as soil, peat, fibrous material or the like to allow growing of a plant, a seedling or a seed. The free end of the insert may be provided with a bowl-shaped opening which, when the insert is mounted to the pipe of the growing module projects out from the outer circumferential wall of the growing module.

The growing system may further comprise a base configured to be attached to a lower end of the lower most growing module, wherein said base comprises a fluid collecting compartment. Accordingly, in the event any surplus fluid should be present, such surplus fluid may be collected in the collecting compartment. The base will also act as a foundation on which the column-like growing systems rests.

According to another aspect, the invention refers to the use of a growing system with the features given above. The growing system may be arranged e.g. on a table or in a window sill.

Further objects and advantages of the present invention will be obvious to a person skilled in the art reading the detailed description given below describing different embodiments.

Detailed description Now turning to Figs. 1 and 2 one embodiment of a column shaped growing system 1000 according to the present invention is disclosed in an assembled form and in a disassembled form respectively.

Starting from the top, the growing system 1000 comprises a tank 100 having an open end 101 to be covered by a removable lid 102. The tank 100 is attached to a first growing module 200a, which in turn is attached on top of a second growing module 200b. The second growing module 200b is attached to a base 300. The interspace between the lower most growing module, in the disclosed embodiment the second growing module 200b and the base 300 comprises an optional partition wall 400, see Fig. 2. The base 300 comprises feet 302 and a spirit level 303.

Plant receiving inserts 500 are provided to be inserted into and be supported by the growing modules 200a, 200b. The individual parts will be described in detail below.

Now turning to Figs. 3 and 4, one embodiment of the tank 100 and the lid 102 is disclosed. Fig. 4 discloses a part of the tank 100 as seen from the below.

The tank 100 is configured to contain a larger volume of irrigation fluid. The irrigation fluid is typically water with or without an addition of a fertilizer.

The tank 100 comprises a circumferential wall 103. The circumferential wall 103 is preferably made of a transparent material in order to allow the user to get easy visual information of the fluid level in the tank 100. The circumferential wall 103 may be provided with a scale (not shown).

The tank 100 comprises a bottom wall 104. The bottom wall 104 may be provided as a cone 105 which diverges towards the circumferential wall 103. The cone 105 will force the fluid contained in the tank towards the lower-most portion of the bottom wall 104.

The bottom wall 104 is provided with through-going draining holes 106. Each draining hole 106 may be provided with a complementary check valve 107. As will be described below, in a condition when the tank 100 is attached to the upper most growing module 200a, the draining holes 106 are configured to be in communication with a respective upper fluid receiving compartment 211 in the upper most growing module 200a. By the check-valves 107 the user may on his/her own discretion set the fluid flow from the tank 100 to the upper most growing module 200a. Depending on how the check-valve 107 is set, the fluid flow may by way of example be fully closed-off, be fully open or partially open to allow a drop-flow only.

The lid 102 is configured to close-off the upper end of the tank 100. The lid 102 may be loosely attached to the tank 100. Alternatively, the lid 102 may be provided with any suitable locking element (not disclosed) such as threads or the like.

As is best seen in Fig. 4, the bottom of the tank 100 may be provided with optional guides 108 extending in the vertical direction. The guides 108 are intended to project into the inner space 203 of the first growing module 200a to stabilize the tank 100 when mounted thereto.

Now turning to Figs. 5 and 6, one embodiment of a growing module 200 will be described. The growing module 200 is disclosed from the top and the bottom respectively.

The growing module 200 comprises an inner circumferential wall 201 and an outer circumferential wall 202, each having a longitudinal extension as seen in the vertical direction. The inner circumferential wall 201 defines an inner space 203 having an open upper end 204 and an open lower end 205. In a condition when two or more growing modules 200 are arranged one on top of each other, the inner spaces 203 of each growing module 200 will together form a combined continuous inner space 206 configured to contain a growing medium. The combined continuous inner space 206 is preferably straight-cylindrical.

The upper and lower ends 204, 205 may be provided with a circumferential rim and recess respectively, thereby providing a vertical support of the growing modules and hence enhancing the stability of the column.

The open upper end 204 comprises two locking tongues 220. Also, the open lower end 205 comprises corresponding locking holes 221. When mounting a first and a second growing module 200a, 200b one on top of the other, the two locking tongues 220 will lockingly engage the locking holes 221 by a snap-fit, see Figs. 7a and 7b. The skilled person will understand that other connecting means may be used. As a non-limiting example, the first and the second growing modules 200a, 200b may be mounted together by a threaded engagement. It is also to be understood that the interface between the growing modules 200a, 200b may be provided with sealings if necessary.

Now turning to Figs. 5 and 6, the open lower end 205 may further comprise two radially extending flanges 222. Each flange 222 comprises a hole 223 configured to receive a screw 224 used to connect the partition wall 400 to the lower most growing module 200b, see Fig. 8.

Now turning to Figs. 5 and 6 anew, the inner circumferential wall 201 defines together with the outer circumferential wall 202 an irrigation space 207 encircling the inner space 203. In the disclosed embodiment, the irrigation space 207 is divided into four different sections. The division is provided by four pipes 208, each pipe 208 extending in the radial direction. A lower fluid receiving compartment 209 is formed between the pipes 208.

Each pipe 208 forms a through-going channel 210 that extends from the inner circumferential wall 201 to the outer circumferential wall 202. The inner space 203 is configured to communicate with the ambience via said through-going channel 210. The through-going channel 210 has a substantially circular cross section, however it is to be understood that other cross-sections are possible.

The part of the pipe 208 that extends between the inner and outer circumferential walls 201, 202 has an outer surface which forms part of an upper fluid receiving compartment 211. The upper fluid receiving compartment 211 has a bottom wall 212 which is provided with a through-going irrigation hole 213. The irrigation hole 213 has a vertical extension and allows fluid that is to be contained in the upper fluid receiving compartment 211 to flow into the through-going channel 210 of the pipe 208. Thereby, growing medium and roots of a plant to be received in the through-going channel 210 may be irrigated.

An upper end of the irrigation hole 213 is encircled by a wall portion 214. The wall portion 214 comprises an opening 215 configured to restrict fluid flow from the upper fluid receiving compartment 211 to the irrigation hole 213.

Each upper fluid receiving compartment 211 comprises two side walls 216 extending between the inner circumferential wall 201 and the outer circumferential wall 202. One of the two side walls 216 comprises an overflow outlet 217 allowing any surplus fluid in the upper fluid receiving compartment 211 to flow in the circumferential direction from the upper fluid receiving compartment 211 to the lower fluid receiving compartment 209 which, as seen in the circumferential direction, is arranged between two adjacent upper fluid receiving compartments 211. It is to be understood that both side walls 216 may be provided with an overflow outlet 217.

To contribute maintaining fluid in the upper fluid receiving compartment 211, the compartment upper fluid receiving compartment 211 may be provided with a porous or a sponge material (not disclosed).

Each lower fluid receiving compartment 209 comprises a bottom wall 218 with a through-going draining hole 219 in its lower most point. The draining hole 219 allows fluid contained in the lower fluid receiving compartment 209 to flow into an upper irrigation fluid compartment 211 of a second growing module 200b to be attached to the open lower end 205 of the first growing module 200a to thereby be arranged below the first growing module 200a in a column.

As is best seen in Figs. 1 and 2, when the growing modules 200a, 200b are attached one on top of the other to form a column, the first and second growing modules 200a, 200b are angularly displaced in view of each other as seen around the longitudinal vertical axis. As an effect thereof, a lower fluid receiving compartment 209a of a first growing module 200a communicates with an upper fluid receiving compartment 211b of a second growing module 200b via the draining hole 219 in the first growing module 200a.

The first and second growing modules 200a, 200b may be identical, no matter intended position in a column of several growing modules 200a, 200b arranged one on top of the other.

The growing modules 200 may be provided by injection molding a plastic material.

Now turning to Figs. 9a-9c, the growing system 1000 comprises plant receiving inserts 500, each insert 500 forming part of a growing vessel. The plant receiving insert 500 comprises a through-going growing channel 501 which is intended to be filled with a growing medium. It is to be understood that the plant receiving insert 500 alternatively may be provided with a pod of growing medium together with a seed.

The plant receiving inserts 500 are configured to be removably attached to the respective pipes 208 of the growing modules 200.

The first free end 502 of the plant receiving insert 500 intended to attach the pipe 208 to the growing module 200 may be provided with a cross-section complementary to that of the pipe 208 of the growing module 200 to allow insertion of the plant receiving insert 500 by a sliding movement. Alternatively, the plant receiving insert 500 may be provided with an optional locking member 507, see Figs. 9b and 9c allowing easy attachment and detachment of the plant receiving insert 500 to the growing module 200.

The opposite, second free end 503 of the pipe 208 intended to face away from the growing module 200 comprises a bowl-shaped opening 504.

As is best seen in Fig. 9a and Fig. 7a, an upper wall portion 505 of the plant receiving insert 500 is provided with a cut-out 506. In a position when the plant receiving insert 500 is attached to the pipe 208 of the growing module 200, the cutout 506 is aligned with the outlet the irrigation hole 213 of the upper fluid receiving compartment 211 of that pipe 208. Thereby, fluid leaving the irrigation hole 213 via its outlet will come in direct contact with the growing medium in the plant receiving insert 500 and wet the same.

Now turning to Figs. 2 and 10, one embodiment of the base 300 is disclosed. The base 300 acts as a foundation. An inner circumferential wall 305 of the base 300 defines a fluid collecting compartment 304.

The lower edge 301 of the base 300 comprises in the disclosed embodiment four feet 302. The feet 302 may be adjustable, e.g. by turning to allow horizontal levelling of the growing system 1000. The base 300 may comprise a spirit level 303 to facilitate levelling.

Now turning to Figs. 2 and 8, the growing system 1000 may comprise a partition wall 400 to be arranged in the interface between the lower most growing module 200b and the base 300. The purpose of the partition wall 400 is to form a bottom to the combined inner space 206 configured to contain a growing medium. The partition wall 400 may be sealingly mounted to the lower most growing module 200b by e.g. screwing. It is to be understood that the partition wall 400 also be may attached in other ways, e.g. by a snap-lock or by a threaded engagement.

The partition wall 400 comprises through-going openings 401 allowing water from the draining holes 219 of the lower fluid receiving compartments 209 in the lower most growing module 200b to flow into and be collected in the collecting compartment 304 of the base 300.

In the following the operation principle of the growing system 1000 will be discussed.

To make the growing system 1000 ready to be used, the user assembles all parts by attaching the growing modules 200 one on top of the other on the base 300. Thereby a vertical column is formed. The number of growing modules 200 may vary depending on desired height of the column. As a non-restricting example two growing modules 200 only or three to five growing modules 200 may be arranged in the column.

To ensure that the growing system 1000 stands properly on a surface, the feet 302 of the base 300 may be adjusted to thereby level the growing system 1000 properly. As an input to the user during levelling, the spirit level 303 may be used.

As the growing modules 200 are mounted one on top of the other, a combined inner space 206 is formed. This combined inner space 206 is filled with a growing medium. The growing medium may be loosely arranged in the combined inner space 206. Alternatively, the growing medium may be contained in a perforated bag (not disclosed) which is inserted from above into the combined inner space 206. The bag may be made of a water permeable material or be provided with perforations to such extent that fluid from the irrigation system may enter the growing medium and also so that roots of the plants may grow into the growing medium.

As a next step, the plant receiving inserts 500 are prepared by being filled with a growing medium. A plant, seed, or a seedling is planted in the bowl shaped opening 504. The plant receiving insert 500 may even be prepared with a pod of growing medium containing a seed. The thus prepared plant receiving inserts 500 are then attached to the respective pipes 208 of the growing modules 200.

As a final assembling step, the tank 100 is mounted on top of the upper most growing module 200a. The tank 100 is filled with irrigation fluid, typically water, and then covered by the lid 102.

The fluid will strive to leave the tank 100 due to gravity via its draining holes 106 and be received in the respective upper fluid receiving compartments 211 in the upper most growing module 200a. Depending on how the check-valves 107 are set, the fluid flow from the tank 100 may be controlled.

The fluid entering the upper fluid receiving compartment 211 in the first growing module 200a will primarily leave the same via the irrigation hole 213 and end up in the growing medium that is contained in the respective plant receiving insert 500. Should the upper fluid receiving compartment 211 be filled with fluid, the surplus fluid will leave the upper fluid receiving compartment 211 in the circumferential direction via the overflow outlet 217 and flow into the lower fluid receiving compartment 209 in the same growing module 200a.

The fluid that is received in the lower fluid receiving compartment 209 will leave the same in the vertical direction via the draining hole 219 in the bottom wall 218 of the lower fluid receiving compartment 209 and flow into an upper fluid receiving compartment 211 of the second growing module 200b which is attached below the first growing module 200a. By the fluid being guided in the circumferential direction in the irrigation space 207 in each growing module 200a, 200b and by the plurality of growing modules 200a, 200b being angularly displaced in view of each other around the longitudinal vertical axis, the fluid will be step wise guided in the vertical direction to the different inserts 500 in the guiding modules 200a, 200b throughout the column.

The same principle will apply until the fluid has passed all growing modules 200a, 200b. Any remaining fluid will be collected in the collecting compartment 304 in the base 300 from which it may be manually removed.

The principle with the fluid provided to the upper most growing module 200a and which is then transferred step-wise to subsequent lower growing modules 200b has similarities with champagne glasses in a champagne tower where the different levels of glasses are gradually flooded and where the surplus fluid fills glasses at lower levels due to a constant inflow of fluid from the top, i.e. in this case from the tank.

When a growing cycle is completed, the user can easily remove the growing medium, disassemble all components and clean them.

The invention has been described as relating to a growing system where each growing module comprising four pipes and hence plant growing inserts. It is to be understood that the number of pipes may be altered.

The plant receiving inserts may with remained function have different shapes than that disclosed.

The growing modules have been described as having a circular cross section as seen in the vertical direction. It is to be understood that other cross sections are possible with remained function. The cross section may by way of example be oval or polygonal such as triangular, quadrangular, heptagonal etc.

All parts may be made of a plastic material by e.g. injection molding.
