Definitions
- the disclosure relates to construction of grow chambers for growing plants.
- the disclosure further relates to systems and methods for growing plants, including systems for growing of plants that employ a number of grow chambers in a stacked arrangement and including methods of using such systems to control and enhance plant growth.
- the disclosure further relates to apparatus and systems for automating the operation of growing systems, including automated components for shifting, lowering, removing or other manipulating of one or more grow chambers in a grow chamber stack.
- U.S. Pat. Nos. 9,848,545 and 10,076,090 to Joseph, et al. disclose stacked farming systems and processes which utilize stackable grow chamber systems for controlling the growth of different sections of a single plant.
- the stack of chambers may surround one or more growing plants, each plant extending within the stack of chambers and having a respective section in each of one or more of the stacked chambers, with each growing chamber surrounding a corresponding portion of the plant, such as a root mass, plant produce, plant stalk, plant canopy, etc.
- the grow chambers may be selectively added or removed during plant growth, with little to no disruption to the plant, such that different sections of the growing plant may be influenced differently by respective surrounding grow chambers and the unique environment that is created and controlled independently from the other chambers and respective plant sections housed therein.
- the grow chamber configurations may thus be utilized to manage and control plant growth, productivity, harvesting and prolong the productive life of the plant, thus enabling unique growing and harvesting methods and processes, providing growing systems that are efficient and productive such that the costs associated with operation are justified by the output produced.
- Such systems provide for increased control and management of plant growth and increase the production (yield), improve the product assortment available from plants, and increase the useful productive life of plants.
- the present disclosure provides improvements to known grow chamber systems and related methods, including improvements that reduce manufacturing costs, improve transportability of grow chambers and grow chamber systems, provide ease of construction, cleaning, storing and use, and that enhance operation and automation. Additionally, site build-out costs may be reduced, since traditional infrastructure components such as lifts, catwalks, racks, frames or the like can be eliminated or reduced in number by the use of stacked grow system architectures that incorporate aspects of the disclosure.
- grow chamber constructions may incorporate standardized parts that are easy and inexpensive to manufacture and transport and which may be quickly assembled into a grow chamber stack whereby each grow chamber provides a controlled environment for a respective section of a single plant or a number of plants extending through the grow chamber stack.
- Each chamber may include a grow chamber frame supported on at least two, and preferably four support columns.
- the chamber frame may define a floor space that may support a number of standardized floor panels, each having at least one plant interface through which the plant may extend such that the floor panels and the chamber may be installed around the plant section without disturbing the plant.
- the plant interface may engage or abut the plant stalk without damaging it and may create a barrier to keep the plant section substantially isolated within the chamber.
- the chamber frame may also define a ceiling or lid space for each chamber that may support a number of standardized or customized ceiling or lid panels, which may have the same configuration as the floor panels and may be installed around the plant section without disturbing the plant.
- Front, back and side panels may be secured to the chamber frame to define an interior space, the environment of which may be controlled, independently of other chambers in the stack, to influence growth of the plant section extending within the grow chamber.
- the chamber frame and support column construction permit removal of the front, back and side panels without removing the chamber from the stack, thereby allowing maintenance, inspection and servicing of the interior chamber space and plant section therein.
- Each support column may include an interface which permits any chamber in the stack, or a portion of the stack, to be lifted, lowered and/or supported in a vertical position, allowing removal of one or more chambers for harvesting.
- the support columns not only may support and/or be integral with the chamber frame components, but may also function as sub-frame components in the chamber stack to permit grow chambers to be stacked upon one another without the need for an external support frame for the overall stack.
- the support columns may include alignment pins and recesses such that an alignment pin of one support column may be received in a recess of an adjacent support column for an associated chamber.
- the alignment pins also provide for efficient removal of chambers from the stack in a harvesting operation as a chamber only needs to be moved a small distance to remove the alignment pins from the recesses of an adjacent chamber and to permit severing of the plant section contained in the chamber and removal of the chamber from the stack.
- the chamber construction supports grow chamber systems and processes for constructing the chamber and a chamber stack as the plant grows and without disturbing plant growth.
- an additional chamber maybe added to a base or an existing grow chamber stack by constructing the new grow chamber on a plant section not under any chamber's control .
- this process can be used to modify plant sections from a canopy or light receiving section to a root or crop productive section.
- sections of the plant can be enclosed by additional chambers and their growth modified.
- the chamber construction and chamber systems support processes for harvesting successive sections of the plant by easy removal of a desired chamber from the stack.
- a harvesting device may automate or assist manual processes for cutting plant sections and raising, lowering and removal of one or more chambers from the chamber stack for harvesting.

- a sealing element 286 may be provided on the interior surface of the exhaust panel 280 .
- FIG. 12 is a perspective view of a floor panel and plant interfaces for constructing the floor of the grow chamber.
- Floor panel may be of a generally geometric shape and formed by injection molding with a plastic material, such as a high strength thermoplastic, stainless steel that is cut into the desired geometric shape or other acceptable materials & fabrication methods.
- the floor panel 292 may include a number of semi-circular or other shaped recesses 294 which each may receive and retain therein a plant interface 296 .
- Interfaces may be a full circle in shape (as in FIG. 2 ) with a single radial slit to permit sealing around the plant stalk while conforming to the floor design & functionality.
- Plant interfaces 296 may function to provide a seal around a plant stalk to prevent the passage of light into the chamber interior and/or to isolate the chamber interior and a plant section from other chambers and plant sections, such that the environment within the chamber and surrounding the specific plant section may be controlled separately and independently from other chamber interiors and respective sections of the same plant. Additionally, these plant interfaces act to help support the plants in the grow stack. Interface may be formed from an elastomeric material that includes an outer retaining channel 297 for frictionally engaging a respective recess 294 . One or more slits 298 may be formed within the interface 296 to permit the interface to engage and/or otherwise interface with the plant stalk.
- the interface may include bristles or other features to provide a substantial sealing engagement with the plant stalk.
- a number of flow channels 293 may be formed in an upper surface of the floor panel 292 and may communicate with one or more passages 295 which permit the flow of liquid within the chamber through the chamber floor to a chamber below or to a base which collects and recirculates liquids in the system.
- each pair of floor panels 292 define three grow passages extending through the chamber floor.
- the six floor panels define nine grow passages, each of which may accommodate a single plant, with each chamber in a chamber stack controlling a respective growth environment for one section of each of the nine plants growing in the chamber stack.
- such panels may be used to form a lid or ceiling on one or more chambers.
- the present disclosure provides for a widely adaptable floor and lid configuration where any number of plant interfaces, in any size, shape and pattern, may be provided to support different crop types.
- the floor panels may be of a standardized and customizable, modular construction. That is, the floor panels 292 may be of identical shape and may fully occupy a floor space defined in the lower chamber frame 230 .
- the lower chamber frame 230 defines a floor space, bounded by the upright walls of the lower chamber members, which may have an L-shaped cross-section.
- the floor space is such that it may be completely occupied by floor panels of a standardized shape, such as a rectangular shape.
- the upper chamber frame 240 may define a ceiling or lid space for supporting ceiling or lid panels (not shown) on one or more of the chambers.
- the ceiling panels may be of a standardized shape as are the floor panels 292 and may be identical in shape (i.e., interchangeable with) the floor panels such that only a single shape panel needs to be manufactured to permit users to configure chambers with floors and ceilings or lids as needed in a given stacked chamber system.
- a lid may be constructed on an upper most chamber in a stack to shield the chamber interior from light.
- the orientation of the support columns 220 is outside of the square floor (and ceiling) space.
- the floor and ceiling or lid panels need not be formed with cutouts or discontinuities in order to fit within the floor space. Not only does this eliminate the need for non-standard shaped floor panels, but it provides for ease of installation, cleaning and maintenance of the chamber interior.
- the grow chamber construction permits a grow chamber to be constructed around one or more growing plant stalks without disturbing the growth of the plant(s).
- the chamber construction permits an operator to first construct the upper and lower frame assemblies 240 and 230 , and then secure them to the upper and lower portions of the support columns 220 using the upper and lower frame adapters.

Abstract
Description
- The disclosure relates to construction of grow chambers for growing plants. The disclosure further relates to systems and methods for growing plants, including systems for growing of plants that employ a number of grow chambers in a stacked arrangement and including methods of using such systems to control and enhance plant growth. The disclosure further relates to apparatus and systems for automating the operation of growing systems, including automated components for shifting, lowering, removing or other manipulating of one or more grow chambers in a grow chamber stack.
- Recent solutions have addressed challenges in the art to make emerging farming technologies more feasible for mainstream use and production of crops and for adaptation on a wide, commercial scale. For example, U.S. Pat. Nos. 9,848,545 and 10,076,090 to Joseph, et al., the subject matter of which is incorporated herein in its entirety, disclose stacked farming systems and processes which utilize stackable grow chamber systems for controlling the growth of different sections of a single plant. The stack of chambers may surround one or more growing plants, each plant extending within the stack of chambers and having a respective section in each of one or more of the stacked chambers, with each growing chamber surrounding a corresponding portion of the plant, such as a root mass, plant produce, plant stalk, plant canopy, etc. The grow chambers may be selectively added or removed during plant growth, with little to no disruption to the plant, such that different sections of the growing plant may be influenced differently by respective surrounding grow chambers and the unique environment that is created and controlled independently from the other chambers and respective plant sections housed therein. The grow chamber configurations may thus be utilized to manage and control plant growth, productivity, harvesting and prolong the productive life of the plant, thus enabling unique growing and harvesting methods and processes, providing growing systems that are efficient and productive such that the costs associated with operation are justified by the output produced. Such systems provide for increased control and management of plant growth and increase the production (yield), improve the product assortment available from plants, and increase the useful productive life of plants. There are continued challenges in the art to make known growing apparatus, systems and processes more suitable for mainstream and widescale production, transport and use and reduce manufacturing and crop production cost.
- There is thus a need in the relevant art for solutions that address the aforementioned challenges and others in the art.
- The present disclosure provides improvements to known grow chamber systems and related methods, including improvements that reduce manufacturing costs, improve transportability of grow chambers and grow chamber systems, provide ease of construction, cleaning, storing and use, and that enhance operation and automation. Additionally, site build-out costs may be reduced, since traditional infrastructure components such as lifts, catwalks, racks, frames or the like can be eliminated or reduced in number by the use of stacked grow system architectures that incorporate aspects of the disclosure.
- According to one aspect, grow chamber constructions may incorporate standardized parts that are easy and inexpensive to manufacture and transport and which may be quickly assembled into a grow chamber stack whereby each grow chamber provides a controlled environment for a respective section of a single plant or a number of plants extending through the grow chamber stack. Each chamber may include a grow chamber frame supported on at least two, and preferably four support columns. The chamber frame may define a floor space that may support a number of standardized floor panels, each having at least one plant interface through which the plant may extend such that the floor panels and the chamber may be installed around the plant section without disturbing the plant. The plant interface may engage or abut the plant stalk without damaging it and may create a barrier to keep the plant section substantially isolated within the chamber. The chamber frame may also define a ceiling or lid space for each chamber that may support a number of standardized or customized ceiling or lid panels, which may have the same configuration as the floor panels and may be installed around the plant section without disturbing the plant. Front, back and side panels may be secured to the chamber frame to define an interior space, the environment of which may be controlled, independently of other chambers in the stack, to influence growth of the plant section extending within the grow chamber. The chamber frame and support column construction permit removal of the front, back and side panels without removing the chamber from the stack, thereby allowing maintenance, inspection and servicing of the interior chamber space and plant section therein. Each support column may include an interface which permits any chamber in the stack, or a portion of the stack, to be lifted, lowered and/or supported in a vertical position, allowing removal of one or more chambers for harvesting.
- According to another aspect, the support columns, not only may support and/or be integral with the chamber frame components, but may also function as sub-frame components in the chamber stack to permit grow chambers to be stacked upon one another without the need for an external support frame for the overall stack. The support columns may include alignment pins and recesses such that an alignment pin of one support column may be received in a recess of an adjacent support column for an associated chamber. The alignment pins also provide for efficient removal of chambers from the stack in a harvesting operation as a chamber only needs to be moved a small distance to remove the alignment pins from the recesses of an adjacent chamber and to permit severing of the plant section contained in the chamber and removal of the chamber from the stack.
- According to another aspect, the chamber construction supports grow chamber systems and processes for constructing the chamber and a chamber stack as the plant grows and without disturbing plant growth. In a growing process, an additional chamber maybe added to a base or an existing grow chamber stack by constructing the new grow chamber on a plant section not under any chamber's control . As an example, this process can be used to modify plant sections from a canopy or light receiving section to a root or crop productive section. Thus, sections of the plant can be enclosed by additional chambers and their growth modified.
- According to another aspect, the chamber construction and chamber systems support processes for harvesting successive sections of the plant by easy removal of a desired chamber from the stack.
- According to another aspect, a harvesting device may automate or assist manual processes for cutting plant sections and raising, lowering and removal of one or more chambers from the chamber stack for harvesting.
- The above and other attendant advantages and features of the invention will be apparent from the following detailed description together with the accompanying drawings, in which like reference numerals represent like elements throughout. It will be understood that the description and embodiments are intended as illustrative examples and are not intended to be limiting to the scope of invention, which is set forth in the claims appended hereto. The drawings show example implementations according to respective aspects of the disclosure.

FIGS. 1-13 illustrate details of anexample growing system 10, and constituent parts according to aspects of the disclosure. Thegrow system 10 may include the major components of abase 100 and a number of (in this case five) grow chambers including a first chamber 200.1, second chamber 200.2, third chamber 200.3, fourth chamber 200.4 and fifth chamber 200.5 in a stacked arrangement.FIG. 1 shows the stack in a partially exploded view to reveal some of the details of the interior of the first and second chambers, which will be further explained herein. Acanopy support 300 may comprise a number of (in this case four) canopy support sections 302.1, 302.2, 302.3 and 302.4, which may be fastened to an upper chamber 200.5 with threaded fasteners to surround a plant canopy or shoot section (not shown) extending from the lid of the upper chamber 200.5. The canopy support sections may be constructed as a grid or framework from common materials and may provide support to the plant canopy/shoot section while permitting the circulation of air. As will be described, an upper frame of each chamber may have holes provided thereon to support thecanopy support 300. - Referring additionally to
FIGS. 2 and 3 , each growchamber 200 may be comprised generally of agrow chamber frame 210, which includes at least two, and in this case four, support columns 220.1, 220.2, 220.3 and 220.4. Thesupport columns 220 support and are interconnected with alower chamber subframe 230 and anupper chamber subframe 240. Afront panel 250 and arear panel 260 may be removably secured to a front and back of thechamber frame 210, respectively. Anintake side panel 270 and anexhaust side panel 280 may be removable secured to respective sides of thechamber frame 210 and may include devices for enhancing or causing circulation of air within the chamber, as will be explained. Achamber floor 290 may be formed from a number of (in this case, six) standardizedfloor panels 292 each having one or more (in this case three) plant interface recesses 294 defined in a side thereof for receiving aplant interface 296, which may engage or abut the plant and may have characteristics of a reslient seal or gasket or include bristles to keep the inner chamber environment controlled independent of other chambers, as will be explained. - With additional reference to
FIGS. 4, 5 and 6 , illustrates further details of the constituent components ofchamber frame 210 and related structure.Support columns 220 may include a solidmain body 221 which may be of a square or other cross-section (i.e., circular, rectangular or any cross-section). A square cross-sectional main body is shown. An upperframe adapter interface 222 is defined on thesupport column 220 for receiving anupper frame adapter 246. The upperframe adapter interface 222 may include ashoulder 226 formed on thesupport column 220 for supporting acollar 247 on theupper frame adapter 246. Thecollar 247 may be shaped complementarily to the upperframe adapter interface 222. An upperframe support plate 248 may extend from thecollar 247 to support theupper frame 240. Thecollar 247 may be retained in place by one or more quick connect fasteners 222.1 which may be a spring-biased pin that retracts into thesupport column 220 and snap into a respective receiving hole 246.1 defined oncollar 246 when the receiving hole 246.1 is aligned with the pin. A lowerframe adapter interface 223 may be defined on a lower portion of thesupport column 220 for receiving alower frame adapter 236. The lowerframe adapter interface 223 may include a shoulder 227 formed on thesupport column 220 for supporting acollar 237 on thelower frame adapter 236. The collar may be shaped complementarily to the lowerframe adapter interface 223. A lowerframe support plate 238 may extend from thecollar 237 to support thelower frame 230. Aninterface 228 may be defined in thesupport column 220 as an elongated slot that extends through the main body of thesupport column 220 for receiving one or more components of a shifting/lowering/supporting device, as will be described in more detail. -
FIG. 7 illustrates an exampleupper chamber frame 240. Theupper chamber frame 240 may be constructed of a number of elongatedframe side members 242, which may have an L-shaped cross-section, joined by a like number of frame joining members, in this case fourcorner members 241. Thecorner members 241 may be secured on the underside of theframe members 242, which may include mitered corners to provide for a smooth upper surface to facilitate easy installation of the upper frame and securing to the upperframe support plates 248 of the frame adapters 246 (FIGS. 4-6 ). Referring additionally toFIG. 2 , in order to provide a smooth surface and substantially continuous surface on the upper frame of the chamber, upper frame spacer strips 243, which are of the same thickness as the upperframe support plates 248 may be provided to extend between adjacentupper support plates 248. Moreover, tapered, recessed fasteners, such as flathead or tapered screws may be used to secure the frame components. Thus, a very smooth and continuous upper surface may be provided on each chamber to facilitate effective sealing between chambers as well as smooth operation when a chamber is removed from the chamber stack as will be described. -
FIG. 8 is an example construction for afront chamber panel 250. The panel may include ahinge 252 which enables the front panel to be pivotably mounted on thechamber frame 210 to enable access to the interior of the chamber. One ormore sealing elements 254, such as a gasket and/or a raised portion, which may provide a friction fit, may be provided to ensure effective sealing between the front panel and thechamber frame 210. Such sealing elements may also be provided on the other panels, such asrear panel 260 andside panels -
FIG. 9 is an exploded view of anexample intake panel 270. Theintake panel 270 may include a generally flat sheet member ormain body 271 having one or more ventilation passages orports 273 defined therein. A retaining ridge 274 may be fastened to an interior side of theintake panel 270 and may interface with and engage an upper edge of one a front lower frame member 231 (seeFIGS. 2 and 4 ), which may allow theintake panel 270 to pivot slightly thereabout to permit the panel to rest in a slightly open orientation for access to the chamber interior. A sealingelement 276 may also be fastened to an upper area of the interior surface of thepanel 270 to provide a sealing engagement with the upper frame 240 (FIG. 4 ).Side members 272 may reinforce the strength of the panel and be provided with sealing edges or surfaces to engage or interface with surfaces on respective support columns 220.1 and 220.2 (FIG. 2 ). One or morevaned cowlings 278 may influence the flow of air or other fluid through the chamber intake panel and may direct incoming air to flow in a radially outward direction relative to the cowling, thus enhancing the distribution and flow of air within the chamber interior. -
FIGS. 10 and 11 are perspective views of aside exhaust panel 280. Theside exhaust panel 280 may have a similar construction to theintake panel 270. A generally flatmain body 281 may have a number ofexhaust ports 283 formed therein, withrespective exhaust fans 288 mounted there on to force air out of the chamber interior. A retainingridge 284 may engage one of the chamber lower frame members and permit slight pivoting of theexhaust panel 280.Side members 282 provide strength and a sealing surface to engage or interface with surfaces on the respective support columns 220.3 and 220.4. A sealingelement 286 may be provided on the interior surface of theexhaust panel 280. -
FIG. 12 is a perspective view of a floor panel and plant interfaces for constructing the floor of the grow chamber. Floor panel may be of a generally geometric shape and formed by injection molding with a plastic material, such as a high strength thermoplastic, stainless steel that is cut into the desired geometric shape or other acceptable materials & fabrication methods. Thefloor panel 292 may include a number of semi-circular or other shapedrecesses 294 which each may receive and retain therein aplant interface 296. Interfaces may be a full circle in shape (as inFIG. 2 ) with a single radial slit to permit sealing around the plant stalk while conforming to the floor design & functionality. Plant interfaces 296 may function to provide a seal around a plant stalk to prevent the passage of light into the chamber interior and/or to isolate the chamber interior and a plant section from other chambers and plant sections, such that the environment within the chamber and surrounding the specific plant section may be controlled separately and independently from other chamber interiors and respective sections of the same plant. Additionally, these plant interfaces act to help support the plants in the grow stack. Interface may be formed from an elastomeric material that includes anouter retaining channel 297 for frictionally engaging arespective recess 294. One ormore slits 298 may be formed within theinterface 296 to permit the interface to engage and/or otherwise interface with the plant stalk. Alternatively, or in combination, the interface may include bristles or other features to provide a substantial sealing engagement with the plant stalk. A number offlow channels 293 may be formed in an upper surface of thefloor panel 292 and may communicate with one ormore passages 295 which permit the flow of liquid within the chamber through the chamber floor to a chamber below or to a base which collects and recirculates liquids in the system. In the illustrated implementation, each pair offloor panels 292 define three grow passages extending through the chamber floor. Thus, the six floor panels define nine grow passages, each of which may accommodate a single plant, with each chamber in a chamber stack controlling a respective growth environment for one section of each of the nine plants growing in the chamber stack. Similarly, such panels may be used to form a lid or ceiling on one or more chambers. As will be recognized by those of ordinary skill, the present disclosure provides for a widely adaptable floor and lid configuration where any number of plant interfaces, in any size, shape and pattern, may be provided to support different crop types. - In accordance with an aspect of the disclosure, the floor panels may be of a standardized and customizable, modular construction. That is, the
floor panels 292 may be of identical shape and may fully occupy a floor space defined in thelower chamber frame 230. Referring back toFIG. 2 , owing to the position of thesupport columns 220, thelower chamber frame 230 defines a floor space, bounded by the upright walls of the lower chamber members, which may have an L-shaped cross-section. The floor space is such that it may be completely occupied by floor panels of a standardized shape, such as a rectangular shape. Similarly, theupper chamber frame 240 may define a ceiling or lid space for supporting ceiling or lid panels (not shown) on one or more of the chambers. The ceiling panels may be of a standardized shape as are thefloor panels 292 and may be identical in shape (i.e., interchangeable with) the floor panels such that only a single shape panel needs to be manufactured to permit users to configure chambers with floors and ceilings or lids as needed in a given stacked chamber system. For example, a lid may be constructed on an upper most chamber in a stack to shield the chamber interior from light. The orientation of thesupport columns 220 is outside of the square floor (and ceiling) space. Thus, the floor and ceiling or lid panels need not be formed with cutouts or discontinuities in order to fit within the floor space. Not only does this eliminate the need for non-standard shaped floor panels, but it provides for ease of installation, cleaning and maintenance of the chamber interior. - As will be recognized, according to aspects of the disclosure, the grow chamber construction permits a grow chamber to be constructed around one or more growing plant stalks without disturbing the growth of the plant(s). Specifically, the chamber construction permits an operator to first construct the upper and
lower frame assemblies support columns 220 using the upper and lower frame adapters. The frame assembly can be placed on top of a first chamber within which the one or more plants are growing and the alignment projections (229,FIGS. 5 and 6 ) of the first chamber. Thefloor panels 292 may then be set in place within the lower frame floor space with therecesses 294 and plant interfaces 296 being placed around respective plant stalks. The front, back and side panels, with intake and exhaust features that provide for venting and/or circulation, may then be installed on the chamber frame and a lid, or additional chamber, may be installed on top of the (second) chamber to form an enclosed and controlled environment in the second chamber for respective sections of the plant(s). As will be recognized, the construction of each chamber in a chamber stack may thus be done to create additional controlled growth sections of existing plants and without disturbing, removing or harming the plant(s). This, in turn, enables the addition of grow chambers to the stack with virtually no disturbance to the plants and while the plants continue to grow. -
FIG. 13 is an exploded view of an example base according to an aspect of the disclosure. As will be recognized, owing to one of the advantage of the present disclosure, the modular components utilized in construction of the upper chambers 200 (FIG. 1 ) including thechamber frame 210 and supportcolumns 220 may also be utilized to construct abase 100. Instead of floor panels, a basin ortray 120 may be supported within thechamber frame 210 on theupper frame 240.Support columns 220 may be provided with adjustable pedestals 150 which support thebase 100, and thus, ultimately, the entire stack of chambers, on a floor surface. A number ofside panels 110 may be provided for aesthetic purposes. -
FIGS. 14.1 and 14.2 illustrate an example growing process that may be facilitated by the above-described chamber constructions. Configurations of the system 10 (FIG. 1 ) corresponding to particular process steps are shown to the left of the example steps. Atstep 1402, the base (“Base”) and first chamber (“C1”) are constructed in place on a surface. Plant growth is initiated, for example, by the placement of a potato start, which may constitute a first section of the plant at a first maturity level in the first chamber. As will be recognized, while a single plant is being referenced for purposes of simplicity in this example, the chambers may support multiple plants (i.e., such as the nine plant interfaces described in the examples with regard toFIGS. 1-13 ). Atstep 1406, when the first section of the plant reaches a second maturity level, which may coincide with the potato start forming a stalk or canopy, which may constitute a second plant section, a second chamber (“C2”) may be constructed around a second section of the plant. As described above, such construction of the second chamber may occur without disruption to the growth of the plant growing in the first chamber. The second plant section may be modified prior to construction of the second chamber, such as by removal of some or all of the leaves growing on the plant stalk in order to modify the second section from a stalk/canopy portion to a root mass/productive portion. The second chamber in this case may include a lid to shield the productive plant section from light and to enclose the plant section. - At
step 1408, when the plant reaches a third maturity level, a third chamber may be constructed around a third section of the plant. This may include a modification of a stalk portion of the plant as was done for the second chamber above. Similarly, atstep 1410, when the plant reaches a fourth maturity level, a fourth chamber may be constructed around a fourth plant section. As will be recognized, in this manner, sections of the plant may be modified with the addition of respective chambers, with each productive plant section having a different maturity level of the crop/produce, with the most mature productive section of the plant being in the first chamber. - In accordance with aspects of the disclosure, the grow chamber constructions disclosed herein not only eliminate the need for an external frame, and associated complexities, to support the chamber stack, but also support efficient and simple removal of chambers as part of a harvesting process. Referring particularly to
FIG. 14.2 , atstep 1420 during a harvesting step, the chambers above the first chamber, that is, the second, third and fourth chambers, are supported via the support interfaces on the support columns on the second chamber. This may be done with a stationary support, schematically represented to the left ofstep 1420, or with a shifting device, as will be described herein. Removal of the first chamber may then occur by either or both ofsteps step 1422, the portion of the stack constituted by the second, third and fourth chambers (C2, C3 and C4) may be elevated with an external lift, as indicated by the arrows. In addition, or alternatively, atstep 1424, the first chamber may simply be shifted a sufficient distance to disengage the alignment projections/connecting pins (229 inFIGS. 5 and 6 ) to permit removal of the first chamber, with or without the base. Lowering of the first chamber and base may occur by virtue of collapsible/extendable mounting features on the base, which permit the base and first chamber to lower a slight distance relative to the supported second, third and fourth chambers, so that the alignment projections clear the recesses of the support columns of the second chamber. Atstep 1426, the first plant section may be severed from the rest of the plant using acutting device. Atstep 1428, the first chamber may be removed and the crop harvested from that chamber's stacked production layer of the plant housed within the first chamber. After harvesting, the remaining chambers C2, C3 and C4 may be lowered onto the base, and another chamber added to the top of the stack to initiate modification of yet another section of the plant from a stalk into a productive section (root mass). As will be recognized, the process provides continued harvesting of crop from successive sections of a single plant. In addition, multiple productive levels of the plant may be developed under a single plant canopy and thus drawing from the same energy source. In this manner, productivity of the plant for a given energy input may be increased. - According to an aspect of the disclosure, chamber shifting devices which facilitate performance of one or more of the steps described above may be provided.
FIGS. 15-31 illustrate aportable shifting device 500 that may be utilized with a number of grow chamber stacks that may be located in a large scale grow operation. Referring toFIGS. 15 and 16 , shiftingdevice 500 may have a generally U-shaped configuration when viewed from the top, with a pair of opposed side frames 520 and 530 connected by arear cross-member 540 and a rearchamber removal carriage 545 pivotably connected to thecross-member 540. Eachside member carriages 550 for releasably engaging respective shifting interfaces (228 inFIGS. 5 and 6 ) on the support columns 220 (FIG. 2 ) on respective chambers in the chamber stack. Shifting carriages 550.1, 550.2, 550.3 and 550.4 engage respective shifting interfaces on a second chamber (not shown inFIG. 15 ) and shifting carriages 560.1, 560.2, 560.3 and 560.4 engage respective shifting interfaces on a first chamber in the chamber stack (not shown inFIG. 15 ). A pair of lead screws 555.1, 555.2, 555.3 and 555.4, on each side member, each actuated by aservo motor 557, provide for actuation of the shiftingcarriages 560. Moreover, as will be explained, each shiftingcarriage 550 may be provided with a locking mechanism and driving mechanism to permit independent movement and locking of the two shifting carriages on each lead screw relative to one another. A pair ofguide rods 558 extend on each side of eachlead screw 557 and are fixed to the side members and extend through a journal in each shifting carriage to provide for lateral support and guidance thereof. A cutting mechanism 590 (FIG. 16 ) is mounted for reciprocating movement on cutting mechanism in a direction parallel to the ground to travel in a space between grow chambers, from the front of the chambers to the back, to sever plant sections, as will be explained. -
FIG. 17 illustrates a shiftingdevice 500 disposed in position around a grow chamber stack having a first grow chamber 200.1 and second grow chamber 200.2. The shifting device may be transported into position on caster or wheel elements disposed beneath the side frames and or cross member. InFIG. 17 , the shiftingcarriages -
FIG. 18 shows the shiftingdevice 500 in position around a pair of grow chambers with thechamber receiving carriage 545 deployed to a horizontal position. Pivoting may occur by manual operation, or by appropriate automated controls and motors.FIG. 18 also shows the upper shiftingcarriages 550 in a chamber-engaging position with theguide rods 553 extended inward towards the second chamber. Referring additionally toFIG. 19 , each shiftingcarriage gripping block 552 having arecess 554 defined therein and shaped to receive the width of a supporting column on the chamber. A lockingbar 556 may be actuated by ahandle 551 through an appropriate linkage, as will be explained and may extend through the shifting interface in a respective support column (not shown inFIG. 19 ) and into a receivingslot 557 in thegripping block 552. In this manner, a respective support column (228,FIGS. 5 and 6 ) may be securely locked in place on each shifting carriage prior to shifting the chamber. Each shiftingcarriage guide rods 553 which provide vertical support to thegripping block 552 and allow it to move horizontally relative to a shifting carriage base 561 (FIG. 19 ), which selectively engages a respective lead screw. Horizontal movement of thegripping block 552 relative to the shiftingcarriage base 561 may be done manually or may be done with controlled motorized components that act upon theguide rods 553 and/or thegripping block 552. -
FIG. 20 shows the shiftingdevice 500 with the shiftingcarriages 550 in a position in which the second chamber 200.2 is lifted from the first chamber 200.1. As will be recognized, there may be additional chambers (i.e., third chamber, fourth chamber) above the second chamber and those chambers would also be lifted into an elevated position above the first chamber. In this position, thecutting mechanism 590 may travel through the space between the first chamber and the second chamber to sever the plant section(s) in the first chamber from those in the second chamber. Operation of thecutting mechanism 590 will be explained below. -
FIG. 21 shows the shiftingdevice 500 with shiftingcarriages 560 in a position in which they engage the first chamber in preparation for shifting the first chamber to permit removal thereof.FIG. 22 shows the first chamber being lifted by the shiftingcarriages 560 to create a space between the first chamber and thebase 100. Referring additionally toFIG. 23 , removal of the first chamber may be facilitated by aroller sled 547 deployed from thechamber removal carriage 545. Achamber receiving frame 548 may be supported with a number oflinkages 549 on thechamber removal carriage 545. Thechamber receiving frame 548 may be pivoted to an elevated position shown inFIG. 23 , in which it is elevated to the same height as the top of thebase 100.Roller sled 547 may then be manually rolled from thechamber receiving frame 548 onto the upper frame of the base.FIG. 24 shows theroller sled 547 in position beneath the first chamber and supported on the upper frame of thebase 100. Further details are shown inFIG. 28 , in which a portion of the shiftingdevice 500 and the first and second chambers have been omitted to show the position ofroller sled 547 on thebase 100. After the roller sled has been put in position beneath the first chamber, the lower shifting carriages are actuated to lower the first chamber 200.1 onto theroller sled 547. The handles on the shifting carriages are actuated to disengage the locking bar from the shifting interfaces of the support columns, and the shifting carriages are retracted from engagement with the first chamber support columns, as shown inFIG. 25 . The first chamber 200.1 may then be rolled onto thechamber receiving frame 548 using theroller sled 547 to the position shown inFIG. 26 . The first chamber may be subsequently lifted from thechamber receiving frame 548 and removed for further processing/harvesting steps for the plant section (crop) contained therein. -
FIG. 29 illustrates details of acutting mechanism 590, which may include a cutting band or wire 591 which extends around a rotating drive motor 592. At an opposite end is a pulley or other element (not shown) to keep the band or wire 591 in tension. Band or wire 591 may travel in a single direction, or it may reciprocate to effectuate severing of the plant section in a chamber below the cutting mechanism 591. Motor 592 and the opposite end pulley may each be mounted on acutting mechanism carriage 593 which may be slidably secured to aguide rod 594 extending from the front to the back of the shifting mechanism frame on each side thereof. Thecutting mechanism carriages 593 may be moved from the front to the back of the shifting mechanism frame with motorized components or with a manually operated linkage that allows an operator to move the assembly along theguide rods 594 and in the space between chambers when severing of a plant section is desired. -
FIG. 30 illustrates details of a linkage between the shiftingcarriage handle 551 and the lockingbar 556. The linkage may include acamming extension 558 extending from the shaft of the handle and being pivotably connected to ayoke 559 extending from the lockingbar 556. Rotation of thehandle 551 causes movement of theextension 558 and corresponding sliding movement of the lockingbar 556 within the shiftingcarriage gripping block 552. -
FIG. 31 is a cross section of a shiftingcarriage 550 showing internal components for driving and locking the shifting carriage. With regard to the locking mechanism, theguide rods 558 may be provided with friction-enhancing features, such as lockingteeth 563 formed in or extending along a side of theguide rod 558. A pair of lockinggrips 564 have mating teeth 565 formed thereon for engaging the lockingteeth 563 of the guide rods and may be mounted for reciprocal movement within journal orhousing elements 566.Linkages 567 connect the locking grips 564 to a crank 568 which may be moved by a motor (not shown) controlled by a control system. These components provide for selective locking an unlocking of the shifting carriage to theguide rods 558. With regard to the locking mechanism, a conical half-nut assembly 570, with two tapered or conical elements that may be biased outward by a spring may be selectively moved upward inFIG. 31 into locking engagement with a conical surface on a locking block 572 secured to the shifting carriage housing. Upward or downward movement of the shifting carriage may be facilitated by anouter actuating tube 574 that surrounds the lead screw and may be moved upward by a camming surface on thecrank 568 such that rotation of the crank results in upward movement of the actuating tube 547 (as well as actuation of the locking grips 564. Due to the taper/conical surfaces in the half-nut halves and in the locking block, the two halves may be forced together upon upward movement until they engage the lead screw and act as a single drive nut. The shifting carriage thus operates in this mode as though it were permanently attached to the lead screw, raising and lowering with no further action upon the half-nut assembly required. When it is desired to disengage the half-nut (i.e., to hold the associated chamber in place) the rotation of the crank in a locking direction may cause the locking grips 564 to engage the locking teeth on the guide rods and, at the same time, the lead screw may be reversed to allow the locking grip teeth to engage the guide rods. In addition, the actuator crank causes a lowering of theactuating tube 574 and the continued rotation of the lead screw may cause the half nut assembly to lower and disengage from the lead screw. The half-nut assembly thus provides selective engagement and disengagement of the shifting carriage with thelead screw 555 and is coordinated with actuation of the locking grips 564 such that the shifting carriage may be unlocked from theguide rods 558 and engaged with thelead screw 555 simultaneously or in a single operation. Alternatively, the locking mechanism and shifting mechanism may be actuated by separate actuators, each under appropriate control by a respective control system, to coordinate their operation. The dimensions of the half-nut may be selected to ensure that the half-nut can completely disconnect while also staying within the lower section of the locking block conical surface to ensure the half nut assembly remains centered at all times. - The above configuration provides for a single lead screw to raise and lower two or more shifting carriages mounted thereon independent of one another. Thus, the shifting carriages 550.1 and 560.1 (
FIG. 15 ) can be moved independent of one another using the lead screw motion and appropriate controls for the driving and locking mechanisms in each shifting carriage. -
FIGS. 32-45 illustrate a second example grow chamber system according to aspects of the disclosure and which may be used to perform the process described above relative toFIGS. 14.1 and 14.2 . Referring particularly toFIGS. 32 and 33 , growchamber system 1000 may include a base orchamber 1100 and a number of modular grow chambers (five are shown) 1200.1, 1200.2, 1200.3, 1200.4 and 1200.5. Atop framework 1300 may be provided on a top one of the chambers 1200.5 and may include anenergy source 1310 suspended therefrom as well as a number ofsupport members 1320 fastened to the corners of the upper chamber 1200.5 and extending above the upper chamber. In addition, other supporting structure may be provided, such as the gridwork shown in the system inFIG. 1 . Ashifting device 1500, which may be a scissor-type shifting device, maybe disposed beneath thebase 1100.Base 1100 may have telescoping support members 1110 (partially illustrated, seeFIGS. 43 and 44 for full illustrations) secured to support columns at the corners of thebase 1110. Rollers orcasters 1112 may be mounted on the bottom of each corner support column. - A second example modular chamber construction is illustrated in the exploded view in
FIG. 34 and in the assembled view inFIG. 41 . Alower frame 1230 is defined by a number (in this case four)channel members 1232 each of which is secured to a lower portion of the corner support columns 1220.1, 1220.2, 1220.3 and 1220.4. Thelower frame members 1232 andcorner support columns 1220 define a floor space, which supports a number of floor panels, includinginner floor panels 1293 and endfloor panels 1292, which have acutout 1294 to fit around thecorner support columns 1220. A number of floorsupport cross members 1233 may extend between two of thelower frame members 1232 and in a direction transverse to the major dimension of the floor panels to provide additional support thereto. Afront panel 1250,rear panel 1260,right side panel 1270 and leftside panel 1280 may be secured to respectivelower frame members 1232 and to thecorner support columns 1220 using threaded fasteners or other fastening devices, such as quick connect fasteners.FIG. 34 also illustrates an upper and lowernutrient distribution framework -
FIGS. 35 and 36 illustrate details of alower frame member 1232 and an example connecting feature for releasably securing thelower frame members 1232 to thesupport columns 1220.Frame member 1232 may be a generally L-shaped angled member having a horizontally extending floor support member with a vertically extendingfastening tab 1240 extending from each end thereof. Avertical wall 1235 may extend between and be fastened to thefastening tabs 1240 with threadedfasteners 1243, welding or other fastening features. Fasteningtabs 1240 include a number (in this case two) of fastening channels or hooks 1242 extending in a downward direction to engage and receive fastening pins on the support columns as will be explained. As will be recognized, thehorizontal member 1234 may be formed from a stamping operation in which fastening tabs are formed and then bent at a 90-degree angle to the orientation shown inFIG. 35 . -
FIGS. 37-39 illustrate details of thecorner support columns 1220 and how they are fastened to thelower frame members 1232.Support columns 1220 may include a roundedouter corner 1221 extending to apanel shoulder 1222 for providing a flush mount of the front, back or side panels. Eachsupport column 1220 may include a pair of lockinglevers 1226, which are mounted onpivot pins 1227 and may pivot (swing) from a stored position, in which they are secured in a springbiased clip 1228 to a locking position (shown inFIG. 39 ) in which the end of the locking levers 1226 engages thefastening tabs 1240 of thelower frame members 1232 to secure the position of the lower frame members and the engagement of lockingpins 1229 in the respective channels of thefastening tabs 1240, thus securing theframe member 1232 to thesupport columns 1220. In accordance with aspects of the disclosure, analignment pin 1225 is provided in a recess oraperture 1224 in the top of thesupport column 1220 for engaging an adjacent recess in the support column of an adjacent (upper) chamber. - In contrast to the modular chamber construction described above with regard to
FIGS. 1-13 , in this example the construction utilizes only a lower frame defining a floor space and utilizing the support columns to interconnect the lower frame constituent members. - The lower frame connections include a high strength quick connect feature, which enhances the structural strength provided by the lower chamber frame and support columns such that an upper chamber frame (as in the system of
FIGS. 1-13 ) may be eliminated or optional. This configuration also provides enhanced access to the chamber interior. Moreover, the corner support columns are disposed inward compared to the implementation ofFIGS. 1-13 , and thus partially occupy the chamber interior and provide a smooth outer perimeter of the grow chamber to enhance cleaning and appearance. -
FIG. 42 is an exploded view of abase 1100 and ashifting device 1500. As will be recognized, thelower frame 1230, cross-members 1233,support columns 1220 and front, back andside panels FIGS. 32-40 . However, a solid floor panel 1190 may be utilized instead of thefloor panels 1292, 1293 (FIGS. 34 and 41 ) in order to provide a smooth surface on the underside of the chamber for interfacing with a lift assembly. Moreover, adrip tray 1180 may be secured to the top of the base 1100 to collect liquids that may drip from the chamber stack above. - Referring additionally to
FIG. 45 , shiftingdevice 1500 may be a scissor-type shifting assembly with anouter frame 1510 and aninner frame 1520 pivotally connected to one another.Inner frame 1510 andouter frame 1520 may havefloor roller elements 1530 to engage a floor surface.Inner frame 1510 andouter frame 1520 may also include chamberfloor engaging rollers 1540, which may engage the floor 1190 of thechamber 1100. A pair of reinforcingbars 1160 may extend across the chamber floor and between two of thelower frame members 1230 to provide structural strength to the base and to prevent deformation during shifting by the shifting device. The reinforcingbars 1160 may be spaced in such a manner that they also function as guides for the chamberfloor engaging rollers 1540. Anactuator 1580, which may be a motor driven lead screw to push and pull upper cross members of the inner and outer frame apart or together to adjust the height of theshifting device 1500. -
FIGS. 43 and 44 illustrate details of a telescoping/adjustable support 1110 that may be quickly and securely fastened to each of thecorner support columns 1220 in order to maintain the vertical position of a portion of the chamber stack, as instep 1420 of the process described relative toFIGS. 14.1 and 14.2 . Eachsupport 1110 may include abracket 1112 which is shaped to engage the outer surface of thesupport columns 1220 on a selected chamber. Quick-release pins 1114 withhandles 1116 may be used to engage holes on thesupport columns 1220 to thereby fasten thesupports 1110 to respective ones of the four support columns on a given chamber. In this manner, the selected chamber and the chambers above it may be supported in a vertical position. Then, the chambers beneath the supported stack may be lowered using the shifting device 1500 a sufficient distance that the alignment pins in the support columns are clear from the recesses in the support columns above them, and removal of the chamber, after severing the plant section as needed, may occur as instep 1424 in the process ofFIGS. 14.1 and 14.2 . - It should be understood that implementation of other variations and modifications of the invention in its various aspects may be readily apparent to those of ordinary skill in the art, and that the invention is not limited by the specific embodiments described herein. It is therefore contemplated to cover, by the present invention any and all modifications, variations or equivalents.
