Hydroponics is a system in which plants are grown in a nutrient solution rather than soil. A variety of hydroponic techniques have been developed including nutrient film technique (NFT), top-feed drip systems, water spray systems, aerosol spray systems (also referred to as aeroponics), wicking systems, deep water culture, raft culture, ebb-and-flow techniques, and systems utilizing fish waste as the plant nutrient (sometimes referred to as aquaponics or aquaculture). Although successful in some situations, conventional hydroponic systems, such as an NFT system, suffer from a number of challenges that have impeded its adoption or widespread success. For example, the needs of plants, including nutrient, water, light, physical support, etc., vary significantly over the plant's lifecycle. This makes it difficult for an integrated mechanical system to meet the needs of a plant as those needs change dramatically over the plant's life cycle. For example, plant roots can create a dam that impedes water (supplemented with nutrients) from reaching plants positioned further downstream of the water flow. As a result, successful hydroponic systems have generally been limited to a small class of plants, such as herbs, lettuce, and tomatoes, that grow quickly and well in a nutrient solution. Accordingly, it is desirable to provide improved techniques for hydroponic systems that can accommodate the changing needs of a plant and can meet those needs at scale.
Various embodiments in accordance with the present disclosure will be described with reference to the drawings, in which:
Systems and methods in accordance with various embodiments of the present disclosure may overcome one or more of the aforementioned and other deficiencies experienced in conventional approaches to cultivating plants. In particular, various embodiments describe methods, services, systems, and apparatuses for a hydroponic growing system that is modular and scalable for growing plants. For example, a plant growing system (e.g., a hydroponic plant growing system) is provided. The system includes, for example, one or more configurable wells operable to hold a nutrient solution for fertilizing and hydrating one or more plants. In various embodiments, the wells can detach from the bottom of the unit. The wells can be hallowed on the inside and can allow the roots of various plants to grow down into them instead of growing outward along the bottom. The system includes an inlet element, outlet element, a control component, among other such elements and/or components. The inlet element is operable to couple to an appropriate transfer component for inlet water and nutrient flow. The outlet element is configured to operate as an outlet for the water and/or other solutions. Outlet element includes an adjustment device configured to control the rate of flow and height of the water and/or solution in the system. The control component is operable to control one or more devices to ensure optimal plant growth and/or plant growth environment.
Advantageously, embodiments described herein provide for sidewalls increased in height, which allows plant roots of larger plants to sit higher above the water, providing the roots with oxygen. Further, because individual wells are smaller than the width of the plant growing unit, water can move along the sidewalls of the plant growing unit to reach other plants. Further still, wells of different depths can be “hot-swapped” without disruption of water to other plants and can accommodate plants of various sized roots. Various embodiments allow for adjustable wells to be converted to fit a spray system to become aeroponics. Further, the wells can provide much-needed nutrients in the situation of an unexpected shutdown, or another event such as pump failure, by maintaining sufficient water until water circulation is established. Further still, whereas conventional NFTs allow for a film of water to move along the bottom, embodiments described herein allow for various heights of water, which lends itself to additional uses, such as an automated cleaning routine. The control unit and various sensors can enable the plant growing system to automate water flow, temperature, humidity, etc., saving time and expense to an owner of such a system. For example, in conventional NFTs, the roots must touch the bottom film, which new growers may find hard to do with young seedlings as their roots have hardly developed. In accordance with various embodiments, the control unit can automatically calibrate the exit flow to increase flow and increase water height to make it easier for those who have planted seedlings to keep the roots moist until the roots further develop to where they can decrease the water height. Further still, the plant growing unit can be made out of more robust materials than a conventional unit to allow a plant support system to be added if desired for larger plants. The support system is designed to allow light to pass through to the plants. The modular plant growing unit includes components to be added or removed, such as automation components, plant support components, various sized wells, and the total size of the plant growing unit. The size of the unit can be designed for one plant or more.
Various other functions and advantages are described and suggested below as may be provided in accordance with the various embodiments.
As shown in this example, the plant growing unit 190 houses the horizontal space around the wells 110 and the horizontal space above the wells 110 (e.g., the system is enclosed). In another embodiment, such as shown in
In the example, water (or nutrient solution, etc.) flows into the plant growing unit 190 through inlet pipe 101 on an inlet end (also referred to as inlet side) of the plant growing unit 190. Water fills and flows through the enclosed horizontal space above the wells 110, passing through the roots of each suspended plant 106. Water exits the plant growing unit 190 through outlet pipe 102 on an outlet end of the plant growing unit 190. The wells 110 may be extended in depth to accommodate the lower roots of plant 106, such that the roots can grow downward (e.g., the roots can be suspended freely over wells 110), as opposed to growing laterally and/or densely within a vertically restricted space. Therefore, roots of plants positioned upstream (e.g., plants closer to inlet pipe 101) will not dam up or impede the water flow to plants positioned downstream (e.g., plants closer to outlet pipe 102).
The bottom of plant growing unit 190 includes nutrient solution containers 110, 111, 112, and 113 (also known as wells, containers, chambers, or other growing media containers.) Although four wells are shown, any number of wells can be utilized in accordance with the embodiments described herein. For example, plant growing unit 190 can be scaled up or down to add more plants if necessary. In an example, plant growing unit 190 can include fewer or additional wells. Wells 110, 111, 112, and 113 can be impermeable as to hold any water or nutrient solution for the lower roots of the corresponding suspended plants, and may be made of stainless steel, plastic, etc.
The wells 110, 111, 112, and 113 are operable to hold a nutrient solution for fertilizing and hydrating one or more plants 116. The wells can detach from the bottom of the plant growing unit 190. The wells can be hollowed on the inside, allowing roots of various plants to grow down into the depth of the wells 110, 111, 112, and 113, instead of growing outward (e.g., laterally) along a uniform floor of a hydroponic enclosure in a conventional NFT (nutrient film technique). Advantageously, such characteristics allow for larger plants to have greater root density to intake nutrients and prevent dams from forming, which can decrease the outlet flow rate. Additionally, if any mechanical components of the plant growing unit 190 were to fail, the water depth of the wells can provide nutrients for the plants to live on without the recirculation of water. Additionally, since plant growing unit 190 is not filled with water, roots of the plants 106 continue to obtain oxygen in the situation where the air pump were to cease operating.
On the inlet end of plant growing unit 190 is inlet pipe 101. Inlet pipe 101 is operable to couple to a tube of metal, plastic, or other material for inlet water flow. Inlet pipe 101 can be placed internally if the system is enclosed (e.g., see
In another example, the reservoir can also filter the water as it recirculates the water. The reservoir can collect used water (e.g., wastewater, drain water, output water, or recirculated water) that is drained out from the outlet pipe 102. It should be noted that water exiting the outlet pipe may be referred to as output water, wastewater, drain water, or recirculated water. For example, output water, drain water, recirculated water, or wastewater may be used to refer to water exiting the outlet pipe. In another example, wastewater may be used to refer to water exiting the outlet pipe that is not recirculated. In yet another example, recirculated water may refer to water exiting the outlet pipe and at least some form of the water reentering the system. For example, recirculated water may exit the outlet pipe, enter a reservoir or other such water system (e.g., a filtration system), and then reenter into the system.
The reservoir may include a pump and a filter in front of the pump, so that the recirculated water can be filtrated as it is pumped back into the system through inlet pipe 101. In another example, the recirculated water may be discarded manually or automatically, and the reservoir is replenished with fresh water. In yet another example, there may be a separate reservoir for collecting recirculated water and another reservoir for supplying fresh water (or nutrient solution).
In accordance with various embodiments, as water flows from inlet pipe 101 to outlet pipe 102, plant growing unit 190 begins to fill water into the wells 110, 111, 112, and 113. The floor of the space above the wells 110, 111, 112, and 113 may be level, and the water may flow from inlet end to outlet end based on water flow rate from inlet pipe 101. In some embodiments, from the inlet to the outlet there is a decrease in gradient to allow the water to easily flow from one side to the other based on gravity.
The flow rate of water moving through the system may be controlled by adjusting the inlet pipe 101, the outlet pipe 102, the pump (not shown), or a combination thereof. For example, the outlet pipe 102 may be adjusted via adjustment device 104 to control the, discussed in further detail in
In another embodiment, the inlet pipe 101 may include an inlet valve (not shown) which adjusts the flowrate of water entering through the inlet pipe 101 may be encased in the inlet pipe 101, wherein a cutout in the inlet pipe 101 exposes the port of the inlet valve. Rotating the inlet valve about an axis parallel to the length of the inlet pipe 101 changes the size of the port of the inlet valve, which changes the flow of incoming water. An actuator may be coupled to the inlet valve to rotate the inlet valve. The actuator may be an electric motor, hydraulic moto, pneumatic motor, and the like.
Plant growing unit 190 can be made out of plastic, metal, composite materials, or other materials or a combination of materials. A top portion of plant growing unit 190 can be removable. Once the top portion is removed, a user can also access the components inside of plant growing unit 190.
Depending on the plant, the distance between the cutouts 105 can be changed to allow for adequate growth (e.g., roots may grow densely, laterally, vertically, etc.) and to use space efficiently (e.g., roots may get tangled with roots of neighboring plants if spaced too closely, but may require longer time for water to reach downstream roots if spaced too far apart). The number of cutouts and/or size (e.g., diameter) of the cutouts can be adjusted to increase efficiency for the type of plant. For example, smaller plants or seedlings may require smaller cutouts, and the smaller size allows for the plant growing unit 190 to fit a higher number of cutouts for more plants. In another example, plants whose roots tend to grow thick or highly fibrous may require lower number of cutouts to increase the distance between cutouts, to prevent roots from getting tangled with roots of a neighboring plant or prevent roots from damming up water from reaching plants downstream.
A cylindrical device 103 can be positioned proximate to each cutout 105. A cylindrical device 103 can, for example, attach to a plant support element (not shown). For example, a plant support element may be mounted onto plant growing unit 190, such as by screwing the plant support element into cylindrical device 103. It should be noted that other mechanisms may be used to secure a plant support element with a cylindrical device, such as a collapsible mechanical pole, magnets, snap connectors, etc. The plant support element may be, for example, a vertical rod, lattice, trellis, etc., which can guide or secure a plant to stay upright. The plant support element is discussed in further detail in
Outlet pipe 102 can have an outlet valve which includes and is controlled by adjustment device 104. Adjustment device 104 is a device which regulates, directs, or controls the flow of water and/or nutrient solution by opening, closing, or partially obstructing a passageway (e.g., valve port, valve opening, etc.) for the water and/or nutrient solution. For example, adjustment device 104 can be a valve, an adjustable valve, adjustment valve device, etc. Adjustment device 104 is attached to outlet pipe 102 and can be configured to control the height of the water in the system as well as the flow rate of water. Adjustment device 104 can be controlled manually or as part of an automated system. In the situation where adjustment device 104 is controlled as an automated feedback system, adjustment device 104 can be controlled based on system or environmental characteristics, such as, for example, the reading of the inlet and outlet flow rate, plant root growth, etc. For example, to determine the flow rate, flow rate monitors can be placed throughout the system to collect such readings. In an example, a flow rate monitor can be placed near the outlet end and/or the inlet end of plant growing unit 190. Individual flow rate monitors can obtain flowrate readings, and adjustment device 104 can be adjusted to control the height of the water. For example, adjustment device 104 may be raised to slow down flow rate, or raised above the water level to stop outlet flow completely. Adjustment device 104 may be lowered to accelerate flow rate. In the situation where the valve of adjustment device 104 is above water (e.g., water remains stagnant in the system), adjustment device 104 may be lowered below the water level to initiate outflow of water.
In yet another example, adjustment device 104 may be rotated to change the flow rate of water. A valve port in adjustment device 104 may be gradually exposed (e.g., the size of the valve port may increase) as it is rotated about the adjustment device 104. In the situation where an environmental characteristic requires low water turbidity (i.e., less particulates or waste in the water) but the automated feedback system reads high water turbidity, the system may control adjustment device 104 to flush the turbid water out quickly. Therefore, adjustment device 104 may be rotated to expose the valve port at its maximum size, increasing outflow of water from the plant growing unit 190.
In another example, the height of the water can be adjusted based on the growth of the roots in the system. In this example, the rate of growth and/or the growth of the roots can be determined by proximity sensors, cameras, LIDAR, etc. The rate of growth and/or growth can be used to adjust the adjustment device 104 to change the water height. For example, during the early development of the plant, the water height should be level with the bottom of the net pots 107 used to suspend the plants above the wells 110, 111, 112, and 113, which allows the rockwool at the bottom of the net pots 107 to absorb water to feed the root system. As such, the adjustment device 104 can be set accordingly such that the water is along the bottom of the net pots 107. As the plant roots grow down into the wells 110, 111, 112, and 113 from the net pots 107, the rate of growth and/or growth of the roots can be used to control adjustment device 104 such that the water height is decreased to allow more oxygen to the roots as the rate of growth increases and/or the growth of the roots increases. Over time, the water can be reduced to a thin layer of water flowing from inlet pipe 101 to outlet pipe 102, refreshing the wells 110, 111, 112, and 113 with oxygen and nutrients as it moves along. With less water in the system, the roots have less chance of developing diseases.
In an embodiment, a pressure valve (not shown) may be attached to the top of adjustment device 202 to move the valve port 201 up or down, changing the water height. The pressure valve may be securely mounted to the top of the plant growing system. In response to environmental characteristics, the pressure valve may push the adjustment device 202 downward or release adjustment device 202 upward along housing 204. In another example, a slide valve may move the adjustment device 202 vertically. Other devices, such as an adjustable valve and actuating arm, can move the adjustment device 202 upward or downward.
In the example, the level adjustment component 200 is also operable to rotate clockwise and counterclockwise about a vertical axis within housing 204, to allow change in the flowrate of water exiting the system through outlet pipe 102. As level adjustment component 200 rotates, valve port 201 becomes gradually exposed (e.g., port, also referred to as valve opening, increases in size) from the housing 204, allowing more water to flow in per unit of time, and flowrate increases. Maximum flowrate may be reached when level adjustment component 200 has rotated such that valve port 201 is completely uncovered by housing 204, allowing for the maximum amount of water to pass through per unit of time. in housing. Level adjustment component 200 may also rotate such that valve port 201 becomes gradually covered by housing 204 (e.g., port diameter, also referred to as valve opening, decreases in size), allowing less water to pass through per unit of time, and flowrate decreases. Flowrate is ceased when level adjustment component 200 has rotated such that valve port 201 is completely covered (e.g., closed) by housing 204. Various environmental characteristics may control when level adjustment component 200 is rotated. For example, when water turbidity is high in the system (e.g., too many waste particulates in the water), the water may need to be drained quickly to reduce chances of plant disease. Level adjustment component 200 may rotate to open or increase the size of valve port 201, increasing flowrate and quickly draining the output water.
In an embodiment, an actuator (not shown) may be coupled to adjustment device 202 to cause rotational movement of level adjustment component 200, changing the flow rate (e.g., of water flowing through valve port 201). The actuator may include an electric motor, hydraulic motor, pneumatic motor, among others. In yet another example, the pressure valve may cause the level adjustment component 200 to move vertically at the same time an actuator causes the level adjustment component 200 to rotate. For example, if the system needs to be quickly drained (e.g., for system maintenance, to transfer an entire set of plants, etc.), the pressure valve may push level adjustment component 200 downward while actuator rotates 200 to open the valve port 201 to its maximum size, thereby lowering the water height and increasing outflow of the water.
Below each cutout 405, a corresponding well (not shown) is positioned in the bottom casing 410. As the wells are enclosed within the bottom casing 410 of fully enclosed plant growing unit 402, they can be accessed and swapped through a removable panel (not shown), for example, along the side of bottom casing 410. The removable panel may be secured to the fully enclosed plant growing unit 402 by magnets, snap connectors, latches, and the like. In another example, the removable panel may be connected to the fully enclosed plant growing unit 402 with hinges and may be swung or lifted open like a door.
In this example, as the fully enclosed plant growing unit 402 is a fully enclosed system, the reservoir can be used for water recirculation. For example, the reservoir can collect the water drained from the outlet and pump the water or nutrient solution back into the system. The reservoir can repeat the recirculation over a plurality of cycles, ensuring that any nutrients in the water that did not get absorbed by the plants during a first cycle (e.g., the first time the nutrient solution flows through the system) can get absorbed during subsequent cycles.
In another example, the reservoir can also filter the water as it recirculates the water through the system. Thus, the outlet pipe (such as outlet pipe 102 of
In an embodiment, the reservoir can include sensors (e.g., pH, water temperature, ambient temperature, light, conductivity, etc.) to detect water quality and/or environmental conditions in the system. In the example, the sensors and other components can be located within the reservoir. In another example, some sensors components may be located in the reservoir while other sensor components are remote the reservoir. In the situation where some of the sensors and components are located in the reservoir, top casing 401 can incorporate lighting, temperature components (e.g., heating and/or cooling components), humidity components (e.g., humidifier and/or dehumidifier), sensors (e.g., temperature, humidity, etc.), and other environmental control components that can be controlled via a control system (not shown).
In an embodiment, the reservoir can include other accessories to treat or modify the water condition in the reservoir. For example, the reservoir may include air stones to aerate the water, or a water heater to change the water temperature, among others. The reservoir may include sensors to monitor the current condition of the water quality and control changes to the condition of the water (e.g., how much oxygen to release into the water through the air stones, when to stop heating the water, etc.). In an example, the air stones can be connected to airline feeds originating from an air pump. In various embodiments, the air pump can be located in the reservoir. In another example, a water heater controlled by the control system is configured to maintain the temperature of the water within one or more setpoints.
In accordance with an embodiment, each well 503 can be associated with a lid 502, which can be used to shut the cavity of the well 503, creating a watertight seal which allows well 503 to be “hot swapped” (e.g., removed from the system without losing water from the system and/or disturbing the continuous flow of water through the system, and without disturbing neighboring plants and their respective wells). In an example, lid 502 can be a sliding plate that slides over well 503 to cover or uncover the cavity of the well 503. Sliding lid 502 to completely cover the cavity of well 503 creates an airtight and watertight seal. A slot 501 between the floor of the plant growing unit and well 503 allows for installment of the lid 502, sliding the lid 502 across well 503, and for storing the lid 502 when well 503 is in an open position (for example, when the well 503 is being used to accommodate suspended plant roots).
Well 503 may be securely connected to plant growing unit, for example, via magnets, latches, clamps, snap connectors, screw thread along the edge of the well 503 and corresponding screw thread around the edge of the cutout 501 for well 503, and the like. Thus, well 503 can be detachable from the plant growing unit, and sliding lid 502 over well 503 prior to detachment to create a watertight seal allows for hot swapping of the well 503 without water loss, water flow interruption, or other disturbance to the system. Further in the example, well 503 may be entirely removed from the system or replaced with a clean well or a different sized well, etc.
In another embodiment, support net 701 may instead be a trellis, lattice, or other structure to support the structure of the plant. Support net 701 and/or rod 700 may also be used to hold parts of the plant in place to assist with pruning, grafting, etc.
Light 801 (also known as an illumination element or light source) can be a white light LED, or other such illumination element, useful in illuminating objects within at least a portion of a field of view of the camera. The device can include other elements useful for imaging as well, such as a light sensor for determining an amount of ambient light. In accordance with various embodiments, growing the roots may require darkness, especially in hydroponics, where algae can grow in the water when the nutrients and lighting come together. While the camera system 800 can be used in the dark, a light 801 can be in place to provide video and photo capture of the roots. For example, a camera can be inside the plant growing unit to provide a view of the inside of the plant growing unit. In another example, each plant can have a camera (e.g., above each corresponding well) to provide a view of each plant. In an embodiment, one or more cameras can be placed to view vegetative growth. The obtained image data (e.g., still images and/or video) can be processed to generate health data for each of the plants, and the health data can be used to control one or more sensors. In various embodiments, lidar can be utilized to provide appropriate data that, when processed, can generate health data for each of the plants.
In another example, the setup may be automated (e.g., smart setup). Sensors may capture image data of the plants or seeds in the system, and the system may be trained to identify the plants deposited into the system. Thus, the interface 900 may automatically select and/or ask the user to verify the type of plant in the system.
User device 1002 is in communication with a resource provider 1007 via the at least one network 1006. The at least one network can include a wired and/or wireless network, as may include the Internet, a cellular network, a local area network (LAN), an Ethernet, an Intranet, and the like. The user device 1002 may have varied local computing resources, such as may include central processing units and architectures, memory, mass storage, graphics processing units, communication network availability and bandwidth, etc.
Resource provider 1007 can provide services for plant growing, monitoring, and maintenance. These services can include, for example, agricultural services, gardening and nursery services, academic research in plant science, plant conservation, horticulture and landscaping, among other such services where modular systems for growing plants are considered. In certain embodiments, provider 1007 can be an intermediary between a customer and a company, such as third-party provider 1032. For example, third-party provider 1032 can utilize resource provider 1007 to provide plant growing services in a modular and scalable hydroponics system, and other services described herein.
Requests for monitoring and/or maintaining a plant growing system can be received to an interface and/or networking layer 1010 of the resource provider 1007. The interface and/or networking layer can include any of a number of components known or used for such purposes, as may include one or more routers, switches, load balancers, Web servers, application programming interfaces (APIs), and the like.
The information can be stored in content data store 1014 and as well as information associated with the user in profile data store 1016 until such information is ready to be processed. Other information may be obtained including, for example, plant data (e.g., the type of plant in the system, economic or industrial purpose for the plant, etc.). For example, intake module 1020 can receive a selection a selection of sources for one or more type of plant. The sources can include, for example, plant-related industries such as agricultural organizations, farming businesses, nurseries, herbal medicine and pharmaceutical suppliers, plant conservation groups, etc. The selected sources can be in response to user input specifying a particular plant type, intended economic use for the plant, etc. In certain embodiments, a configuration file or other instructions associated with the plant data can be obtained that specifies one or more plant type and economic purpose of the plant.
Once the sources are identified, a variety of methodologies may be used to retrieve the relevant plant data, including but not limited to, data scrapes, API access, etc. Intake module 1020 obtains plant data associated with the selection. The plant data can be stored in data store 1030 or other appropriate data store. The plant data can include, for example, the type of plant to be grown in the system, related or substitutable/alternative plant species, a timeframe or expected deadlines (e.g., to reach plant maturity, cultivation, harvesting, etc.), geographic region and geographic restrictions on the plant type, etc.
In certain embodiments, intake module 1020 can process the data to determine and configure, for example, environmental characteristics (e.g., in a configuration file) required for the appropriate plant and other information such as geographic restrictions or use restrictions on the plant type, etc. In certain embodiments, intake module 1020 can determine the specific devices required in a system to execute plant growth for the type of plant. For example, if a selected plant requires specific humidity, low water turbidity, high lighting, etc., intake module 1020 can configure the system to include misters, installation of lighting sources, appropriate number and types of water filters, fans for air circulation, etc. When the plant growing system is set up for the specified plant type, intake module 1020 also obtains environmental data (e.g., current environmental conditions in the plant growing system). Environmental data may be stored in a data store 1033.
Control module 1018 is operable to compare environmental data with the plant data (e.g., environmental characteristics required for the specified plant type). In the situation where the environmental data deviates from the environmental characteristics (for example, current water temperature drops below pre-configured temperature range), control module 1018 can control one or more of the devices to adjust the current conditions in the plant growing system. Devices can include, for example, devices operable to controlling the flow rate, lighting, nutrient dosing, pH, etc. For example, in the situation where the air temperature is too high and the humidity is too low for the specified plant type in the system, control module 1018 may cause a heating/cooling device to decrease the temperature and an actuator to rotate the adjustment device to increase the flow of water through the system to meet the requirements as identified in the preconfigured environmental characteristics for the specified plant type.
The devices may be activated by device module 1022. Device module 1022 can also monitor the condition and status of the devices in the system. For example, power to a lighting device may need to be restored or recharged, a water filter may need to be discarded and/or replaced, etc.
Reporting module 1024 is operable to provide reports and/or notifications to a user or other appropriate entity relating to the status of the system. A report or notification may inform a user how well the plant growing system is running and compare usage data (e.g., information about one or more plants, their environment, whether the plants and/or environmental data meet predetermine environmental settings, etc.). The reports and/or notifications may be presented to a user via content server 1012 or another appropriate component.
In accordance with various embodiments, additional or alternative components and elements can be used in such a system in accordance with the various embodiments. Accordingly, it should be noted that additional services, providers, and/or components can be included in such a system, and although some of the services, providers, components, etc., are illustrated as being separate entities and/or components, the illustrated arrangement is provided as an example arrangement and other arrangements as known to one skilled in the art are contemplated by the embodiments described herein.

A hosted computing environment may also be referred to as a cloud computing environment.
Control component 1111 is operable to obtain data for one or more plants in a plant growing system as well as data about the environment for those plants, and automatically control aspects of the environment to facilitate optimal plant growth and health. In an embodiment, control component 1111 is in communication with user interface component 1101 operable to generate an interface that provides a view of information associated with one or more plants and the environment of those plants for a plant growing unit. In certain embodiments, the interface can present a view of one or more plants, the inside of a plant growing unit, or some other aspect/area of the system. A user can select a plant from the user interface and can be presented a view of sensory data 1100 associated with the plant and/or environment. Sensory data 1100 can include environmental data (e.g., current conditions), for example, pH, conductivity, flow rate, turbidity, water temperature, air temperature, humidity, water temperature, plant growth rate, plant size and dimensions, and the like.
The sensory data can be stored in data store 1103. Data store 1103 can be local or remote to control component 1111. As used herein, the term “data store” refers to any device or combination of devices capable of storing, accessing and retrieving data, which may include any combination and number of data servers, databases, data storage devices, and data storage media, in any standard, distributed or clustered environment.
Configuration file 1102 is operable to configure and store settings (e.g., threshold settings or setpoints) for one or more plants and environmental conditions. For example, the settings can represent the ideal plant and/or environmental values (e.g., setpoints for environmental characteristics) for optimal growth, such as predefined ranges or thresholds for pH, water conductivity, water flow rate, water turbidity, water temperature, ambient temperature, etc. required for the specific plants in the system. For example, if a plant requires high humidity during its early stages and low humidity during its adult stages, configuration file 1102 may configure settings for acceptable humidity ranges based on the type of plant and the plant's age. Configuration file 1102 may establish a default setting for various plant types. For example, configuration file 1102 may establish a default setting for all tomato plants that includes a predefined air temperature range, humidity range, and concentration of nutrient solution, based on the requirement of an average tomato plant at a given age.
During operation, the sensory data (or other parameters of the plant growing unit) can be monitored and compared to stored settings in configuration file 1102. In the situation where the sensory data fails to satisfy designated setpoints or another threshold, control system 1111 can control one or more devices 1105 to optimize the environment contained in the plant growing unit. Devices 1105 can include, for example, devices operable to controlling the flow rate, lighting, nutrient dosing, pH, etc. For example, in the situation where the air temperature is too high and the humidity is too low for tomato plants in the system, control component 1111 may cause a heating/cooling device to decrease the temperature and an actuator to rotate the adjustment device (as in adjustment device 104 of
The system can continually monitor the plants and/or environment, and update the settings or setpoints in configuration file 1102 as the plants grow and the environment changes. For example, sensory data can be analyzed, and the results can be used to, for example, decrease water, nutrient, and light usage, along with other control parameters over time. The settings can be updated based on a set interval (e.g., hourly, daily, weekly, etc.), manually, an event (e.g., particular growth rate, plant growth amount, temperature, pH, etc.) In an embodiment, one or more setpoints can be updated based on data obtained from other users. For example, a user can, for a set of plants, begin with an initial set of setpoints for those plants. Usage data from systems of other users can be obtained. The usage data can include for example, information about one or more plants, and information about the environment of those plants. This information can include, for example, setpoint values, plant types, plant growth data, environment data, etc. Additional information can be obtained as well, including, for example, timestamp data, and other data to correlate different sets of data.
The usage data can be analyzed to determine a score that quantifies how well a particular plant is growing. The score can be compared with one or more thresholds. For example, a score that satisfies a first threshold may indicate a plant with suboptimal growth, a score that satisfies a second threshold may indicate normal growth, and a score that satisfies a third threshold may indicate optimal growth.
The usage data can be continuously analyzed, and the scores can be used to optimize setpoints for one or more systems. For example, the setpoints can be used to automatically update a user's system. In some embodiments, a message can be presented to a user that optimal setpoints are available. In the situation the user accepts the setpoints, the system can be updated. In various embodiments, a user can manually update the setpoints. A user may also be allowed to share setpoints for their system with other users. For example, a user who has found success with one or more setpoints can share those setpoints with other users so that those setpoints may be implemented in their systems.
In an embodiment, the system can capture image data (e.g., still images and/or video) or other data such as lidar data of one or more plants and/or the plant environment. The data can be captured periodically, manually, in response to an event, or a combination thereof. The data can be stored in data store 1103. In an example, as one or more plants grow, images of the root system and the vegetative growth of one or more plants can be captured and stored.
In accordance with an embodiment, the image data can and other data can be used as training data to train a model such as a neural network or another appropriate machine learning-based model to determine optimal setpoints for a given system, optimal plant environment type, etc. The image data can include, for example, images of roots and other aspects of a plant. The image data can be labeled or otherwise classified (e.g., healthy, not healthy, etc.) In some embodiments, the image data can be associated with additional data, such as environmental conditions, a timestamp, etc. The training data can be obtained from a plurality of control systems, and a training component can learn various combinations or relations of features of plant and optimal growing conditions such that when plant and/or environmental data is obtained, a model can be used to evaluate the data and output the appropriate information so that control component can optimize the environmental conditions for optimal plant growth. In various embodiments, models can be trained for specific plant varieties, environments, and the like. Examples models include, for example, logistic regression, Naïve Baye, random forest, neural network, or support vector machines (SVMs), convolutional recurrent neural network, deep neural network, or other types of neural networks or models, and/or combination of any of the above models, stacked models and heuristic rules. Various other approaches can be used as well as discussed and suggested elsewhere herein.
In an embodiment, control component 1111 can detect or receive an indication of the end of the plant growing cycle. In this situation, the system can initiate a process to clean the system automatically. For example, the system can increase the water temperature and add cleaning detergents to kill off microbes, which may affect the next set of plants growing in the system. If previous plants were to have obtained any disease, system cleaning can ensure a clean, sterile environment for the next grow. The system can check turbidity and conductivity to not only check nutrients during the growing period but also check that detergents have left the system. Users can then connect a hose to the system to drain off the detergent filled water or have it already connected to a drain enabling the user to have a fully automated system. For the later system, a drain valve can be added to the system, which would be normally closed and called by the control system to open if and when the system no longer needed to recycle water.
The system can include a communications component 1104 configured to communicate with, for example, remote servers, database systems, other plant growing controllers, computing devices, sensors, logging services, alert systems (e.g., a fire alarm), building automation systems, and the like.
Reporting component 1106 can be configured to allow a user or other appropriate entity to see how well the system is running and compare usage over time and if any adjustments should be made. Over time this data will help others who own the system with a multitude of plants and improve how the system is used and operated and how it is programmed. For example, the data can be used to tune a system to operate more efficiently or at least to operate in accordance with one or more setpoints or other thresholds.
In accordance with various embodiments, the various components described herein may be performed by any number of server computing devices, desktop computing devices, mainframe computers, programmable logic controllers, and the like. Individual devices may implement one of the components of the system. In some embodiments, the system can include several devices physically or logically grouped to implement one of the modules or components of the plant growing unit. In some embodiments, the features and services provided by the system may be implemented as web services consumable via a communication network. In further embodiments, the system is provided by one more virtual machines implemented in a hosted computing environment. The hosted computing environment may include one or more rapidly provisioned and released computing resources, which computing resources may include computing, networking and/or storage devices. A hosted computing environment may also be referred to as a cloud computing environment.
The process obtains environmental characteristics and determines 1208 whether environmental data satisfies the environmental characteristics. An automated feedback system may continuously collect and compare environmental data with environmental characteristics. Environmental characteristics can be settings that include setpoints, ranges, and thresholds for environmental conditions that are required for a particular plant type to grow optimally. For example, environmental characteristics may include predefined ranges or thresholds for pH, water conductivity, water flow rate, water turbidity, water temperature, ambient temperature, etc. required for the specific plants in the system. The environmental characteristics may be stored in a configuration file or entered manually. For example, if a plant requires high humidity during its early stages and low humidity during its adult stages, the configuration file may configure settings for acceptable humidity ranges based on the type of plant and the plant's age. In another example, default settings may be established for various plant types. For example, a default setting may be established for all tomato plants that includes a predefined air temperature range, humidity range, and concentration of nutrient solution, based on the requirement of an average tomato plant at a given age.
If the environmental data does not satisfy the environmental characteristics for the plant type in the plant growing system, the process determines 1210 whether the wells need to be swapped (e.g., removed and/or replaced). In the example, a well containing too many waste particulates may need to removed and discarded. In another example, the roots above a well may grow too long and require its current well to be replaced with a deeper sized well. In accordance with an embodiment, a well can be associated with a lid that can be used to shut the cavity of the well, creating a watertight seal which allows the well to be “hot swapped” (e.g., removed from the system without losing water from the system and/or disturbing the continuous flow of water through the system, and without disturbing neighboring plants and their respective wells). The well may be securely connected to the plant growing unit, for example, via magnets, latches, clamps, snap connectors, screw threads, etc. Thus, the well can be detachable from the plant growing unit, and closing the well with the lid prior to detachment creates a watertight seal which allows for hot swapping of the well without water loos, water flow interruption, or other disturbances to the system.
In accordance with an embodiment, if the well does not need to be replaced, but other environmental conditions must be adjusted to satisfy the environmental characteristics of the plant type, then the process identifies and changes 1214 the other environmental condition. For example, an environmental characteristic can require low water turbidity (i.e., less particulates or waste in the water) but the automated feedback system reads high water turbidity, the system may control an adjustment device attached to the outlet pipe to flush the turbid water out quickly. For example, the adjustment device may include an outlet valve partially encased in a housing at the outlet pipe. When the adjustment device is rotated about an axis parallel to the length of the outlet pipe (e.g., about a vertical axis), the outlet valve may be gradually covered or exposed by the housing, thereby increasing or decreasing the flowrate of water exiting the outlet pipe. The adjustment device may also be moved upward or downward, such that the position of the outlet valve controls the water height in the system. Thus, in this example, the adjustment device may be lowered and/or rotated to increase the size of the outlet valve, such that the turbid water can exit the system quickly. In another example, an inlet valve partially encased in a housing at the inlet pipe may be rotated about an axis parallel to the length of the inlet pipe, to cover or expose the inlet valve to change the flowrate (e.g., of the incoming water).
In yet another example, other environmental conditions may be changed to satisfy the environmental characteristics. The system may activate various devices to control, for example, the lighting, nutrient dosing, water pH, etc. For example, in the situation where the air temperature is too high and the humidity is too low for tomato plants in the system, a heating/cooling device may decrease the temperature, lighting devices installed above the well may be shut off, and an actuator may rotate the adjustment device to increase the flow of water through the system.
The process obtains 1224 environmental data (e.g., current environmental conditions in the plant growing system) and/or plant data (e.g., current quality of the plant). For example, environmental data can include current values of pH, conductivity, flow rate, turbidity, water temperature, air temperature, humidity, water temperature, plant growth rate, plant size and dimensions and the like. Sensors (e.g., pH sensors, oxygen sensors, thermometers, light sensors, conductivity sensors, pressure sensors, etc.), cameras, and the like can be used to collect the environmental data and/or plant data. Sensors may be located within various location in the plant growing system. For example, the sensors for detecting water quality (e.g., pH sensors, turbidity sensors, etc.) can be positioned within a water reservoir which collects output water from the outlet and filters and pumps freshwater into the inlet. Such sensors can thus measure the current quality of the water exiting the system (e.g., after flowing through the plant roots) as well as the quality of the water entering the system (e.g., the water used to feed the plant roots).
In another example, lighting devices and cameras, etc., may be placed inside the plant growing unit above the wells and beside the suspended plant roots to illuminate the area periodically and collect image data of the current conditions of the plant. For example, plant data based on collected image data may include the health status of the roots (e.g., infestation or infection information, healthy color, etc.), the size of the roots, growth rate, any obstruction or entanglement with neighboring roots, root density (e.g., dense roots dam up water flow to downstream plants), etc.
The process compares and determines 1226 whether the environmental data and/or plant data meets the configuration file settings. The environmental data and/or plant data may be collected and compared periodically, manually, based on an event, or a combination thereof. For example, environmental data and/or plant data can be collected over a predefined time interval (e.g., hourly daily, weekly, etc.). The data collection and comparison may also be triggered based on an event (e.g., particular growth rate, plant growth amount, temperature reaches above a threshold, pH changes by a predefined value, waterflow decreases by a predefined rate, etc.).
When the environmental data and/or plant data fails to meet the configuration file settings, the process updates 1228 the environmental conditions accordingly. For example, one or more devices can be identified in the configuration file as appropriate for adjusting the environmental conditions necessary to return the system to the configured settings for the plant. Such devices can include, for example, devices operable to controlling the water flow rate, lighting, nutrient dosing, pH, etc. For example, if environmental data indicates oxygen levels in the water are below a preconfigured threshold for the plant, air stones may be lowered into the water (e.g., water reservoir) to aerate the water. In another example, airline feeds in the water reservoir can be connected to an air pump to aerate the water and increase the water oxygen levels to meet the threshold as set in the configuration file.
