Aspects of the present disclosure relate to the field of farming systems. Specifically, aspects of the present disclosure are directed to a vertical farm and irrigation system for improving and/or enhancing various features of an agricultural growing system.
The need for fresh food is growing as the population increases and fluctuates in the climate impacted growing seasons. The current food supply model, based on traditional farming methods and long distance shipping, is economically and environmentally unsustainable. Traditional farming operations are usually located in agricultural areas, which require large upfront costs, large acreage and high operational costs from seed to sale.
Therefore, there is a need for efficient farming systems and methods and improvements thereto.
Urban agriculture faces obstacles in providing space for growing plants. Space for farming is limited in cities and rarely sufficient to meet a high demand. High start-up and operating costs of greenhouses make local crop production difficult for many businesses. Structures intended to support rooftop greenhouses, for example, must be evaluated by structural engineers and often require additional bracing to support the weight. Urban gardens often must address contaminated soil. Hydroponic systems are not easily used in urban locales, as most hydroponic systems are meant to be installed in agricultural settings, are not easily transportable, and require extensive training of personnel for operation. Thus, self-contained agricultural systems have recently been developed for generating high-yield crops. Such self-contained systems may be located in unused buildings, such as warehouses, or in specialized or repurposed closed or semi-closed environments and often utilize vertically oriented plant arrangements.
In one example approach, such systems may be contained, such as within a modular container or other closed housing (whether fixed or mobile), and may include a growing system that includes various features to support agricultural production, such as a germination station for nurturing seeds until they germinate into plants, a plurality of vertical racks to hold the growing plants, a lighting system to provide appropriate light for the plants, an irrigation system to provide nutrients to the plants, a climate control system to control the environmental conditions within the container, a ventilation system for providing airflow to the plants, and a monitoring system to monitor and control the components of the growing system. Examples of various such features are shown and described with respect to U.S. Pat. No. 10,271,486 titled Insulated Shipping Containers Modified for High-Yield Plant Production Capable in Any Environment, issued Apr. 30, 2019 (also attached hereto as Attachment 1); U.S. Pat. No. 11,026,380 titled Vertical Assembly for Growing Plants, Jun. 8, 2021; U.S. Pat. No. 10,785,925 titled Insulated Shipping Containers Modified for High-Yield Fungi Production Capable in Any Environment, issued Sep. 29, 2020; U.S. Patent Publication No. 2019/0133026 titled Modular Farm Control and Monitoring System, published May 9, 2019; U.S. Patent Publication No. 2020/0037524 titled Modular Farm with Carousel System, published Feb. 6, 2020; and U.S. Patent Publication No. 2020/0359569 titled Hub and Spoke Modular Farm System, published Nov. 19, 2020, each of the foregoing of which is hereby incorporated herein by reference in its entirety.
Various areas that need improvement or enhancement include those relating to aspects of watering and/or nutrition-related features supporting growing crops, including, for example, components making up a system that retains plants in a manner that enables the plants to be readily and easily positioned for growing, such as in a vertical arrangement, watered easily and efficiently during retention in the growing orientation, readily and easily removed from the growing orientation, including for harvesting, but also with regard to temporary removal for other purposes, such as to clear or service various parts of the watering and nutrition components of the system. Such watering and nutrition components may include, for example, various features that deliver moisture and nutrition to individual plants and may need to be regularly serviced.
Problems with existing approaches to vertically-oriented plant growth include roots or other portions of plants growing into or otherwise becoming entwined with wicking elements and/or other components of the system for retaining the plants. For example, roots may grow into the porous aspects of the wicking system and become difficult to remove or extract, and/or the retaining system may include various fabric or other porous materials into which plant roots or other plant features may become entwined. Further, as the roots of the plants grow into the felt wicking and/or other material, the material typically degrades and becomes contaminated by algae or other biological contaminants that utilize nutrients and compete with the crop itself. See, for example, the image of a wicking element with entwined roots and other materials shown
Aspects of the disclosure relate to a vertical farm system. In one example aspect, the vertical farm system comprises, at least one rack having a grow channel, a source of moisture or nutrients, wherein the moisture or nutrients are communicably deliverable to the at least one rack, first and second malleable material inserts receivable in the grow channel, each of the malleable material inserts having an edge area and the first insert being receivable within the grow channel so as to abut the second insert to form an abutting pair of edges therebetween, and a spacing component receivable between the abutting pair of inserts, wherein the spacing component and the abutting edge areas cooperatively form at least one opening extending about the spacing component, the source of moisture or nutrients being communicable to the at least one opening.
In one example aspect, the vertical farm system comprises, at least one rack having a grow channel, a source of moisture or nutrients, wherein the moisture or nutrients are communicably deliverable to the at least one rack, at least one malleable material insert receivable in the grow channel, the malleable material insert having a slot, the insert being receivable within the grow channel so as to have first and second edges of the slot forming an abutting pair of edges therebetween, and a rod component receivable between the abutting pair of edges of the insert, wherein the rod component and the abutting edges ooperatively form at least one opening extending about the rod component, the source of moisture or nutrients being communicable to the at least one opening.
In one example aspect, the vertical farm system further comprises a source of light or access to a source of light.
In one example aspect, the vertical farm system further comprises a source of airflow.
In one example aspect, the vertical farm system further comprises a wrap at least partially encapsulating the malleable material inserts.
In one example aspect, the wrap is water impermeable.
In one example aspect, the vertical farm system further comprises at least one plug or plant, when the vertical farm system includes the first and second malleable material inserts, the at least one plug or plant being receivable between the abutting pair of inserts, and when the vertical farm system includes a malleable material insert with a slot, the at least one plug or plant being receivable between the abuttable pair of edges of the slot.
In one example aspect, the received plug or plant communicates with at least one opening.
In one example aspect, the spacing component comprises a rod.
In one example aspect, the rod comprises plastic.
In one example aspect, the rod comprises one or more notches for creating the at least one opening.
In one example aspect, the vertical farm system further comprises a funnel attached to the rod for guiding the moisture and nutrients towards the at least one opening extending about the spacing component.
In one example aspect, the funnel comprises one or more notches for creating the at least one opening.
In one example aspect, the at least one opening forms at least a portion of a channel.
According to one example aspect of the disclosure, an irrigation system usable with a vertical planting system is provided, the vertical planting system including at least one rack having a grow channel, a source of moisture or nutrients, and a source of light or access to a source of light, the irrigation system comprising: a plurality of malleable material inserts, each of the malleable material inserts having at least one edge area, the plurality of malleable material inserts each being receivable within the grow channel, wherein a first one of the plurality of inserts abuts at a first one of the least one edge area with a first one of the at least one edge area of an adjacent second one of the plurality of inserts, and a spacing component receivable between the first one of the plurality of inserts and the second one of the plurality of inserts between the abutting edge areas, wherein the spacing component and the abutting edge areas form at least one opening extending about the spacing component, wherein the source of moisture or nutrients is communicable via the at least one opening with at least a portion of a plant received within the vertical planting system.
The accompanying drawings, which are incorporated into and constitute a part of this specification, illustrate one or more example aspects of the present disclosure and, together with the detailed description, serve to explain their principles and implementations.
Aspects of the present disclosure include various features of an irrigation system that address and overcome the shortcomings described above, as well as others. An example irrigation system in accordance with aspects of the present disclosure includes use of abuttingly placed pairs of foam or other malleable material, optionally encased in plastic or other material wrap that prevents root or other plant growth into the malleable material. A plurality of vertically inserted spacing components, such as plastic rods, may be emplaced between the abutting pairs of encased malleable materials, wherein each vertically inserted spacing component may cause a channel or channels, and/or other openings proximal to each inserted spacing component to be formed between the encased malleable materials into and/or through which moisture and/or nutrients may flow.
In other aspects of the present disclosure, the malleable material is not encased. For example, there may be a need to reduce production cost. One way to reduce the production cost is to omit the encasing of the malleable material. Thus, in some aspects, the extent to which protection is provided to roots growing into the malleable material may be weighed against the cost associated with encasing the malleable material. The teachings of the present disclosure may be implemented with or without the encasing of the malleable material, based on user preference.
Additional advantages and novel features of these aspects will be set forth in part in the description that follows, and in part will become more apparent to those skilled in the art upon examination of the following upon learning by practice of the disclosure.
Aspects of the present disclosure relate to improvements and/or enhancements to various features of an agricultural growing system, including, but not limited to watering and/or nutrition-related features supporting growing crops, such as various components making up a system that retains plants in a manner that enables the plants to be readily and easily positioned for growing, such as in a vertical arrangement, watered easily and efficiently during retention in the growing orientation, readily and easily removed from the growing orientation, including for harvesting, but also with regard to temporary removal for other purposes, such as to clear or service various parts of the watering and nutrition components of the system, as well as other benefits.
As shown and described with respect to
In accordance with aspects of the present disclosure,
A rod or other spacing component 310 may be placed into the slot or pair of edges 325, so as to spaceably form channels or other openings 330 (
As shown in
In operation, moisture (e.g., water) and/or nutrients may be delivered via emitter 315 (
Among other advantages over the related art of using wicking type components and other similar approaches to watering that may enable root or other entwining plant growth, aspects of the present disclosure enable removal of a plurality of plants to be readily performed in a simple process. The approach of using a single spacing component 310 results in the roots of plants growing about and along the length of the spacing component 310 throughout each rack 304. Cleaning of the system and/or harvesting of the plants, for example, may thus simply involve readily extracting the spacing component 310 from the system along with the plants attached by their roots thereto, thereby avoiding, among other things, the difficulties of separating roots/plants from a wicking strip and/or other porous feature-related problems of the related art. Moreover, since the spacing component 310 may comprise somewhat, or completely impermeable material, such as plastic, and the roots may grow about the spacing component 310 while remaining unattached to the wrap or spacing component 310, the plants may be readily harvested by merely being slid along the spacing component 310 until freed at the end. Thus, the irrigation system in accordance with aspects of the present disclosure may further reduce labor during harvesting and/or system cleaning, as well as other problems of the related art.
In other aspects, an optional funnel 328 is placed at the first end (e.g., the upper end) of the spacing component 310 to guide the moisture and/or nutrients towards the one or more channels 330 formed by the spacing component 310 being emplaced within the abutting edge 325 between the pair of wrap (320) covered foam or other malleable material inserts 301, 302.
Alternatively to the implementation shown in
Alternative to the implementation shown in
In operation, moisture (e.g., water) and/or nutrients may be delivered via emitter 315 (
