The present invention relates to systems, methods and apparatus for multi-dimensional conveyor which allows for the planting, growing and harvesting of plants and plant material in a manner which optimizes yield, allows for consistency, allows production to be automated, and allows production to proceed in conditions which may be most favourable to product biologic activities associated with plants and/or plant products. The apparatus can be constructed of lightweight, cost-effective materials, which afford mass-production and mass-array into vast automatic growing operations.
With many jurisdictions decriminalizing the use of cannabis (C. sativa), there has been more interest in cultivating this crop. Artificial grow rooms and greenhouses have been and are starting to be used in the production of cannabis. Growing cannabis in artificial grow rooms and/or greenhouse allows for more controlled growth conditions which is safer, more predictable and easier than growing outdoors. Greenhouses offer protection from the elements and provide a longer growing season, allowing growers in northern regions the ability to grow crops either with traditional clones or from seeds. Mother nature and a Greenhouse add complexity to being able to control a critical precise environment
The growth and maturation of many plant crops, particularly cannabis, require very specific conditions to optimize the grow conditions for each particular strain or variant of the plant. There is a need at present for the large scale production of such plants both to supply emerging food and energy markets and to offset impacts to food supplies and land usage created by the increasing usage of traditional food sources as fuel and the increasing global populations placing pressures on food, water, fuel stocks, land and other resources. There is also greater demand for consistency as medical therapies using cannabis products require consistency of efficacious ingredients. Prior inventions had addressed portions of the needs far automated or high-density production of crops for food and biomass, but had not addressed these optimal characteristics.
There is also a need to be able to harvest the plants with minimal disturbance to the plants and to the people tasked with harvesting the plants or parts thereof. In order to substantially increase the production of food and other material, there is a need to fully automate farm production, as well as to produce crops within optimized structures. In addition to increasing the speed of production, increasing the speed of harvest, and reducing labor and materials costs, automation will allow the growth of plants in conditions which may be optimal for plants, such as optimal ratios between O2 and CO2, lighting, temperature, nutrient chemicals, temperature humidity, Vapor Pressure Deficit etc.
Previous inventions have failed to address these concerns. Not surprisingly, a number of patent references disclose aspects of the plant production, namely systems and methods for automating the growth and maturation of plants within climate controlled environments. For example, U.S. Patent Application No. 20170094920 teaches incubation and cultivation system for regulated plant growth. U.S. Pat. No. 8,533,993 teaches a horizontal and vertical continuous loop “zig zag” conveyor system for cultivating plants (e.g. potted sugar cane, corn, sorghum, etc.). In the conveyor, young plants start on the framework at the beginning of a lower, horizontal traverse than travel across the lower, horizontal traverse, where they ascend the conveyor along the reversing traverses and helical path of a vertical column on the framework as they mature into adolescent plants, the adolescent plants cross over along an upper, horizontal traverse on the framework to a second vertical column on the framework, where they descend the conveyor along the reversing traverses and helical path of the second vertical column until they reach final maturation at the starting position, where they may be harvested. International Patent Publication No. WO2014066844A2. The '844 Publication teaches a system that includes an enclosed space defining a controllable environment chamber. The system also includes at least one monitoring device configured to measure multiple characteristics of an environment within the chamber. The system further includes multiple actuators configured to alter the characteristics of the environment within the chamber. The enclosed space includes at, least one rack system configured to be placed within the enclosed space. Each rack system includes multiple layers configured to receive multiple plants to be grown in the chamber. The actuators may be configured to adjust the characteristics of the environment within the chamber to condition the environment based on the plants to be grown in the chamber. U.S. Patent Application No. US2012054061 teaches system for growing produce having an insulated enclosure housing having a heating, ventilation, and air conditioning (“HVAC”) system that maintains a positive air pressure within the enclosure, at least one non-compartmentalized growing tray, at least one production lane comprising at least one gravity feed growing rack and at least one watering station, wherein the gravity feed growing rack advances the growing tray along the production lane toward the watering station.
There, remains, however, a need for an automated multi-dimensional, multi-tiered conveyor system, apparatus, method and workflows that can be adjusted based on the nutrient and growth requirements of the plants for optimal growth.
Accordingly, it is an object of this invention to at least partially overcome some of the disadvantages of the prior art.
The present invention is directed to systems, apparatuses and methods for automating the growth and maturation of plants, particularly cannabis, or plant material to optimize inputs, growing time, potency, etc.

The growth and maturation of particular plant crops, particularly cannabis, may require very specific parameters, conditions, etc. to optimize the grow conditions for each particular strain or variant of the plant as well as the physical, biological and biochemical properties and profiles of the plant as well as compounds that may be harvested from the plants. Embodiments of the present invention are directed to systems, apparatuses and methods for automating the growth and maturation of plants, particularly cannabis, to optimize inputs, growing time, potency, etc.
The present invention is directed to a growing apparatus for growing plants, particularly cannabis, comprising; (a) a climate controlled grow tunnel having a plurality of movable tiers, each tier having a plurality of plants disposed therein, each tier having separate climate controls such that a plurality of growing environments is provided within the growing apparatus; and (b) at least one access point providing an operator with access to the plurality of plants as they move through the growing apparatus.
Embodiments of the present invention can maintain precision climate and artificial daylight conditions as required by the plant and has the ability to monitor all grow related parameters which, in a preferred embodiment, can be used to analyze the specific growth data and parameters so as to optimize the specific growth conditions (e.g. a growth recipe) for the plant depending on type, strain, desired production result and other factors.
The present invention allows the automation of: (a) the plant delivery at the access point of the system for maintenance (e.g. trimming and inspection) on a timed interval basis which allows efficient utilization of personnel; (b) the reduction of cross contamination from personnel in the grow operation; (c) the optimization of building space and resources (e.g. heating, cooling, electricity costs, etc.); (d) the stability of the environmental conditions within the grow tunnel allowing energy efficient control of a precision environment; and (e) the ability to measure by multiple sensor and/or sensory arrays all conditions applicable to the monitoring and integration into an optimized plant yield plan, process, or operation.
The invention provides the ability to control the environmental growing conditions, including temperature, humidity, pressure O2/CO2 concentration, etc. relative to the surrounding zone to control odor and the utility costs associated with a precision grow operation. The invention provides the ability to monitor and automatically adjust many factors, including but not limited to Temperature, Humidity, CO2%, O2%, Real time measurement of viable and non-viable contamination, etc. Other key factors include, Vapor Pressure Deficit in the chamber for calculation of Temperature/Humidity set-point, Nutrient input composition and flow measurement, Nutrient waste composition and flow measurement for measuring plant uptake of nutrients, Plant leaf color, with comparison to Light intensity sensor, at various levels within the plant canopy. Distance from canopy height to light source, Plant Root Humidity and Temperature, weight of the plant during the grow cycle, etc.
The embodiments of the present invention also provide the ability to mitigate odor and noise production. There may also be provided the ability to control the irrigation/fertilization requirements, and the impact on over/under irrigation, including standing water and its impact on contamination control. More particularly, the embodiments of the present invention provide the ability to reduce contamination during inspection and harvesting/maintenance. The embodiments of the present mention also allow operators to detect and control pests and contamination, such as mold and other diseases, parasites, insects, animals, etc., effectively and efficiently without the use of pesticides and other undesired chemicals.
The embodiments of the present invention also minimize the labor required to handle, monitor, maintain and harvest the plants. The environmental mixed load conditions of a grow room which have a day and night condition, may: (a) cause equipment meant to control the environment to be subject to significant fluctuations in load conditions: and (b) the fluctuation resulting in a difficulty maintaining precision control of the conditions that affect growth. The present invention allows access to the plants or plant material and provides the necessary infrastructure components to precisely control the temperature humidity and other controlled conditions affecting the environment.
The embodiments of the present invention provide the ability to track each plant from seed or clone to harvest, including the ability to track input (e.g. water, light, nutrients, plus others etc.) on a per plant basis. The invention also provides that ability to maintain a consistent height of the light source from the canopy height. In a preferred embodiment, female plants may be required to produce the high value flower that is used to either smoke/vape/concentrate. Cannabis growth can be started one of two ways: Seed or Clone. In Seed, the seed is germinated and then kept in a high humidity, bright, and warm (21° C.-23° C.) environment to start growth. The plant is then grown to a similar size as a clone. Seeds can be either male or female and need to be sexed during the vegetation/flower stage to identify and remove the males. If there are any male plants in the room with the females, the crop will be lost. The females will produce seeds and not the high value flowers.
In clone propagation, a branch—with leaves—is taken from a mother plant. The mother plant is known to be a good producer of the strain/strength required. Mother plants may be all female, hence all cuttings/clones from the plant will be female. Once a clone, or seed, is large enough; has at least two or three serrated leaves, and can support itself, it's moved to a vegetative room/state. In the vegetation state, the room conditions may be changed to an 18 hr on/6 hrs off lighting period (referred to as a “photoperiod”), and 20° C.-25° Cc. temperature range with 50-65% humidity, for two -three weeks before heading to flower. This is done to stimulate fan leaf growth, which allows the plant to gather the required light energy for growth. Night time temperatures should be 5° C.-8° C. (no more than 10° C.) cooler than day temperatures. A slight breeze is introduced to facilitate strong stalk growth. This air movement will continue during the flowering stage. Once in flower, the light period changes to 12 hrs on/12 hrs off to simulate fall conditions that cause the plant to go into flower (bloom) phase. The flower phase can be from 8-12 weeks depending on strain and room conditions. Generally, 18° C.-26° C. temperature range is needed with 40-55% humidity. Some strains may want it warmer or cooler. Night time temperatures should be 5° C.-8° C. (no more than 10° C.) cooler than day temperatures. The master grower will determine what is required for their plants.
The embodiments of the present invention are directed to a growing apparatus for growing plants, particularly cannabis, comprising: (a) a climate controlled grow tunnel having a plurality of movable tiers, each tier having a plurality of plants disposed therein, each tier having separate climate controls such that a plurality of growing environments is provided within the growing, apparatus: and (b) at least one access point providing an operator with access to the plurality of plants as they move through the growing apparatus.
The embodiments of the present invention maintain precision climate and artificial daylight conditions as required by the plant and the ability to monitor all grow related parameters which, in a preferred embodiment, can be used to analyze the specific growth data and parameters so as to optimize the specific growth conditions (e.g. a growth recipe) for the plant depending on type, strain and other factors.
The present invention allows the automation of: (a) the plant delivery at the access point of the system for maintenance (e.g. trimming and inspection) on a timed interval basis which allows efficient utilization of personnel; (b) the reduction of cross contamination from personnel in the grow operation; (c) the optimization of building space and resources (e.g. heating, cooling, electricity costs, etc.); (d) the stability of the environmental conditions within the grow tunnel allowing energy efficient control of a precision environment; and (e) the ability to measure by multiple sensor arrays all conditions applicable to the monitoring and integration into an optimized plant yield plan, process, or operation.
