     TECHNICAL FIELD 
     The present disclosure relates to the field of horticulture, and more specifically to the field of fluid dynamics in horticulture to optimize production and promote a consistent attributes of plant materials. 
     BACKGROUND 
     In order to grow prolifically, most plants require specific environmental conditions, which are often not provided by outdoor cultivation. However, indoor cultivation allows for farmers to control aspects, such as airflow, air temperature, and humidity, of a plant&#39;s environment to meet specific environment conditions. Because more farmers realize that indoor cultivation is more effective than outdoor cultivation, they are searching for effective ways to control the environment for certain commercial plants, such as mint, sage, raw cocoa, flax seed, hibiscus, tomatoes, hemp, hops, and  cannabis . One of the most important aspects for indoor cultivation of plants is generating ideal air conditions. Indoor cultivators are constantly searching for effective ways to control the flow of tempered air within a grow room to help simulate the best weather conditions for their plants. However, existing systems of air drying for plants cause issues such as nonoptimal humidity levels, wind damage, and inconsistent temperature levels. 
     Humidity and temperature levels in a plant&#39;s environment can affect the growth, drying and other attributes of the plant depending on each type of plants unique growing conditions, drying conditions and the desired yield. Existing drying systems fail to provide consistently optimal levels of humidity and temperature. Nonoptimal humidity levels and inconsistent temperature can cause inconsistencies in plant material attributes such as smell, moisture levels, physical appearance, texture, size, shape and other attributes. Varying plant growth and plant material drying inhibits cultivators from achieving consistent quality in the same harvest or replicating strands of buds or flowers from previous yields. 
     Inconsistent moisture levels may also caused by direct air flow within existing plant drying systems which use either stationary or oscillating fans, or other types of air movers. Direct air flow on plan material during the drying process may damage plants, which may reduce the amount of buds and flowers, in a drying room and may also cause inconsistent drying and inconsistent moisture levels and other attributes for the plant material. The wind damage may also vary the quality and other attributes of the plants. 
     Existing plant drying systems use methods that cause the plant material to quickly over dry and lose water weight, leading to underachieving quality goals and undesirable attributes. Existing drying systems may often sometimes affect the output of the final product sold to the consumer. 
     As a result, there exists a need for improvements over the prior art and more particularly for a more efficient way of providing optimal fluid dynamics for drying plant material to reach ideal environmental conditions.

     DETAILED DESCRIPTION 
     The following detailed description refers to the accompanying drawings. Whenever possible, the same reference numbers are used in the drawings and the following description to refer to the same or similar elements. While disclosed embodiments may be described, modifications, adaptations, and other implementations are possible. For example, substitutions, additions, or modifications may be made to the elements illustrated in the drawings, and the methods described herein may be modified by substituting reordering or adding additional stages or components to the disclosed methods and devices. Accordingly, the following detailed description does not limit the disclosed embodiments. Instead, the proper scope of the disclosed embodiments is defined by the appended claims. 
     The disclosed embodiments improve upon the problems with the prior art by providing a system that effectively dries plant material for optimal plant material attributes. The system allows for an isolated flow of consistently tempered air that avoids damaging the plant material by configuring an air supply, a duct, an air mover, and a dehumidifier in an enclosed space to efficiently control air flow and the drying process. The enclosed space includes a ceiling and a wall to help isolate the flow of air so that there is more control on the humidity and temperature of the air. The air supply provides the airflow with a controlled temperature. The duct, which receives air flow from the air mover, includes a plurality of holes in a preset pattern to also contribute to the maintenance of tempered air by evenly distributing the air from the air supply. Additionally, the plurality of holes is positioned on the duct to prevent the plants from receiving direct air flow, which effectively prevents wind damage. The dehumidifier allows the humidity in the enclosed spaced to be maintained at optimal levels for efficient plant drying and other processes. 
     Referring now to the Figures,  FIG.  1    is a perspective of a plant material drying system  100 , according to an example embodiment. The system for drying plant material includes an enclosed space having a ceiling  105 , a wall  110 , an enclosed space first portion  115  and an enclosed space second portion  120 . In the present embodiment, the enclosed space has a plurality of walls  110 ; however, a single wall spanning from the floor to the ceiling may also be used and is within the spirit and scope of the present invention. 
     The system also includes an air supply  122  that comprises an air supply vent  125  and an air return vent  130 . The air supply vent is near the bottom of the air supply and allows tempered air, which is air that is adjusted to a specific temperature, to enter the enclosed space proximate to enclosed space first portion  115 . The air return vent is near the top of the air supply and retrieves air near the ceiling proximate to the enclosed space first portion. The air return vent allows the retrieved air to be recycled by the air supply to produce more tempered air. This air supply is a type of AC unit that provides better control of the temperature within the enclosed space than other styles of AC units. The system further includes at least one air mover  135  having an air mover inlet  140  and an air mover outlet  145 , wherein the at least one air mover is positioned proximate to the ceiling  105  at the enclosed space first portion and close to the air supply vent. Types of air movers may include axial air movers, centrifugal air movers, and compact air movers. However, other types of air movers may be used that are within the spirit and scope of the present invention. 
     The system includes a duct  400  horizontally arranged and having an elongated body  405 , a duct open first end portion  410 , and a duct closed second end portion  415 . The duct open first end portion is proximate the air mover outlet  145  of the at least one air mover such that air moves from the air supply vent, then to the air mover, then substantially horizontally from the duct open first end portion to the duct closed second end portion. The duct may be made from plastic and having flexible properties. The duct may be made from carbon steel, stainless steel, aluminum, Titanium, other metals or alloys, composites, ceramics, polymeric materials such as polycarbonates, such as Acrylonitrile butadiene styrene (ABS plastic), Lexan™, and Makrolon™. However, other materials may be used that are within the spirit and scope of the present invention. The duct may be formed from a single piece or from several individual pieces joined or coupled together. The components of the duct may be manufactured from a variety of different processes including an extrusion process, a mold, welding, shearing, punching welding, folding etc. However, other types of processes may also be used and are within the spirit and scope of the present invention. In the present invention the duct may be a simple lightweight duct sock. 
     To receive a consistent flow of air from the air mover, the duct open first end portion  410  is in attachment with the air mover outlet  145  and proximate to the air supply vent. The duct includes a plurality of openings  420  spaced apart in a predefined pattern on the elongated body allowing air into move from inside the duct to outside the duct in the enclosed space. The pattern of the openings may be adjusted subject to the conditions further described below. 
     A dehumidifier  150  is positioned proximate to the enclosed space first portion. The system maintains a drying space  155  within the enclosed space, wherein the drying space comprises between 60-68 degrees Fahrenheit and between 58-62 relative humidity. The dehumidifier intakes air from the enclosed space, removes moisture from the received air, and exhausts the received with a lower water content back into the enclosed space. Types of dehumidifiers may include absorption dehumidifiers or refrigeration dehumidifiers. Absorption dehumidifiers allow air to pass through desiccant material to absorb water from the air. At least one fastener  160  attaches the duct to the ceiling  105 . The fastener may include hooks, brackets, bolt, set crews, opening configured to attached to protruding element, socket screws, u-bolts, twine, etc. However, other types of fasteners may also be used and are within the spirit and scope of the present invention. 
     The enclosed space includes the ceiling  105  and the wall  110  to define the dimensions of the enclosed space. The enclosed space helps control the plants&#39; environment and maintain temperature and humidity levels by providing more isolation to the system of air flow. The enclosed space also includes the enclosed space first portion and the enclosed space second portion. The enclose space first end portion includes the air supply, air mover, and dehumidifier. The enclosed space second portion may comprise the part of the duct  400  that includes the plurality of openings  420 . 
     In the present embodiment, the air supply  122  may be a ductless split system that uses an outdoor unit containing a condenser and compressor and a wall-mounted AC unit installed indoors. The outdoor unit provides refrigerant, which is a cooling fluid, via tubing to the indoor AC unit such that the refrigerant helps the AC unit temper the air. The AC unit is a wall-mounted AC unit, which is usually attached to a wall near the near ceiling. The AC unit does not have extra parts or ducts that retrieve or exhaust air outside a room. The wall-mounted AC unit includes a vent near the bottom of the AC unit that supplies tempered air to enter the room. The AC unit also includes a vent near the top of the unit to retrieve un-tempered air that tends to rise to the top of a room. This upper vent allows the AC unit to recycle un-tempered air within a room for the AC unit to produce tempered air. Other AC unit systems, such as stand-alone or multi-split systems, that provide tempered air to the enclosed space are within the spirit and scope of the present invention. 
     The air supply vent  125  of the air supply  122  provides tempered air into the enclosed space proximate the enclosed space first portion. The air supply is configured to provide air with a temperature that consistently maintains the required temperature of the drying space  155 . 
     The air return vent  130  of the air supply  122  retrieves air from the enclosed space first portion to be recycled by the air supply. The air return vent is above the air supply to recycle the air that has lost its original temperature because hot air tends to rise. The air return vent includes an air return sensor  165  that tracks the temperature of the enclosed space to help the air supply calculate the required temperature for the tempered air. The sensor facilitates temperature of air being provided by the air supply vent  125  to help maintain the temperature of the drying space. 
     The air mover  135  includes the air mover inlet and the air mover outlet. The air mover inlet faces the air supply  122  while the air mover outlet faces the duct such that the air is flowing towards the duct. The air mover transfers the tempered air from the enclosed space first portion into the duct for the duct to distribute throughout the room. In one embodiment, the air mover may be a can fan attached to the ceiling via fastener  160 . The fastener may include hooks, brackets, bolt, set crews, opening configured to attached to protruding element, socket screws, u-bolts, twine, etc. However, other types of fasteners may also be used and are within the spirit and scope of the present invention. 
     The duct  400  guides the flow of tempered air from the air mover in a substantially horizontal direction and distributes the air from the duct open first end to the duct closed second end. The duct closed second end allows the duct to build pressure such that the tempered air is forced out of the plurality of openings. The plurality of openings  420  is positioned in a predefined pattern configured to evenly distribute tempered air into the enclosed space. The predefined pattern is configured to avoid damage to the plant material in the drying area by flowing the air in directly downward angles such that the air is not flowing directly into the plant material. The positioning of the plurality of openings also allows the flow of tempered air to avoid hitting the ceiling and creating deadhead thereby maintaining the temperature in the flow of tempered air. The plurality of holes is spaced apart at a predefined distance along the length of the drying area within the enclosed space second portion. The duct may include polymeric materials such as polyethylene, including high density polyethylene, low density polyethylene, linear low density polyethylene, medium density polyethylene, or polypropylene. The duct may be made of other materials and is within the spirit and the disclosure. The duct may be formed from a single piece or from several individual pieces joined or coupled together. The components of the duct may be manufactured from a variety of different processes including a polymerization process, polycondensation process, etc. However, other types of processes may also be used and are within the spirit and scope of the present invention. 
     The dehumidifier  150  comprises a dehumidifier inlet  170 , dehumidifier outlet  175 , and dehumidifier sensor  180 . The dehumidifier inlet retrieves air from the enclosed space proximate to the enclosed space first portion  115  to filter out a certain amount of humidity. The dehumidifier helps maintain the required range of humidity levels in the drying space. The dehumidifier outlet exhausts the filtered air back into the enclosed space proximate to the enclosed space first portion. The dehumidifier sensor tracks the relative humidity of the air in the enclosed space. The dehumidifier is configured to remove a certain amount of humidity depending on the humidifier sensor such that the optimal level of humidity is maintained in the enclosed space. The dehumidifier aims to keep the humidity level of the air in the enclosed space around 58-60 relative humidity. This level of humidity is ideal for the drying of the plant material in the drying space  155 . The dehumidifier may remove  205  pints of water per day. However, other embodiments may be used and are within the spirit and scope of the present invention. 
     The fastener  160  may include a hook, bolt, opening configured to attached to protruding element, u-bolts, etc. However, other types of fasteners may also be used and are within the spirit and scope of the present invention. The fastener attaches the duct to the ceiling so that the duct may flow air into the drying area. 
     Referring now to  FIG.  2   , a side view of the plant material drying system  100  is shown, according to an example embodiment. The system for drying plant material comprises an enclosed space having a ceiling  105 , a wall  110 , an enclosed space first portion  115  and an enclosed space second portion  120 . An air supply  122  provides tempered air into the enclosed space proximate to enclosed space first portion. At least one air mover  135  having an air mover inlet  140  and an air mover outlet  145  is positioned proximate to the ceiling at the enclosed space first portion. The system further comprises a duct  400  horizontally arranged and having an elongated body  405 , a duct open first end portion  410  and a duct closed second end portion  415 . The duct open first end portion is proximate to the air mover outlet  145  of at least one air mover  135  such that air moves substantially horizontally from the duct open first end portion to the duct closed second end portion. A plurality of openings  420  is spaced apart in a predefined pattern on the elongated body  405  allowing air into move from inside the duct to outside the duct in the enclosed space. A dehumidifier  150  is positioned proximate to the enclosed space first portion. The system also includes a drying space  155  within the enclosed space, wherein the drying space comprises between 60-68 degrees Fahrenheit and between 58-62 relative humidity. 
     The air mover transfers the air from the enclosed space proximate to the enclosed space first portion  115  in a substantially horizontal direction towards the enclosed space second portion  120  or drying area. The air moves into the air mover inlet  140  in the A direction and out of the air mover outlet  145  in the A 1  direction. In the same direction, the air flows into the duct to be dispersed into the drying space  155 . 
     The drying space  155  is under the duct and proximate to the enclosed space second portion. The drying space includes the plant material needing to be dried. The term “plant material” used in this application may include any combination of mint, sage, raw cocoa, flax seed, hibiscus, tomatoes, hemp, hops, and  cannabis . However, other types of plants, flowers and organic material may be used within the spirit and scope of the present invention. The drying space is under the duct because the duct releases tempered air through the plurality of openings  420 , which is positioned in a predefined pattern to release air. The predefined pattern includes a row of circular cutouts on each side of the vertical midline of a traverse cross-section of the duct and positioned 30 degrees below the horizontal midline of said traverse cross-section of the duct. Positioning the openings below the horizontal midline directs airflow away from the walls and ceiling to prevent deadhead and changes in temperature. This predefined pattern is also configured to avoid damage to the plant material by flowing the air at a downwards angle to create the drying space around the plants instead of directly flowing the air into the plants. Because the duct is enclosed, the air pressure increases within the duct to allow air inside the duct to be released at an increased velocity. The air in the drying space comprises temperatures between 60 and 68 degrees Fahrenheit and humidity levels between 58 and 62 relative humidity. These ranges of temperature and humidity level are considered to be optimal conditions for the drying or moisture removal of the plant material within the drying space. These conditions avoid over drying the plant material such that the plant material holds a favorable water weight for effective plant drying. 
     Referring now to  FIG.  3   , a top view of the plant material drying system  100  is shown, according to an example embodiment. The system for drying plant material comprises an enclosed space. An air supply  122  having an air supply vent  125  and air return vent  130  provides tempered air into the enclosed space. At least one air mover  135  having an air mover inlet  140  and an air mover outlet  145 . The system further comprises a duct  400  horizontally arranged and having an elongated body  405 , a duct open first end portion  410 , and a duct closed second end portion  415 . The horizontal arrangement allows the duct to span parallel to the dimensional plane of the ceiling. In the present embodiment, the at least one air mover and the elongated body of the duct may be substantially centered along an enclosed space midline  185 , which represents a horizontal line that spans through the middle of the enclosed space. The air mover may also be positioned in front of the air supply vent to receive freshly tempered air. The duct open first end portion is in attachment to the outlet of the at least one air mover such that air moves substantially horizontally from the duct open first end portion to the duct closed second end portion. A plurality of openings  420  spaced apart in a predefined pattern on the elongated body allowing air to move from inside the duct to outside the duct in the enclosed space. The system also includes a dehumidifier  150 , which has a dehumidifier inlet  170  and dehumidifier outlet  175 , that removes a certain amount of humidity from the enclosed space. The elongated body  405  of the duct has a length  425  that spans a substantial portion of the enclosed space. The elongated body of the duct may have a length that is longer than the drying space but shorter than the length of the enclosed space. This allows the plurality of holes to distribute the tempered air throughout all the drying space. 
     The air return vent  130  is proximate to the top of the enclosed space first portion  115  because some of the tempered air may increase in temperature when hitting the wall or ceiling of the enclosed space. The increase in temperature may cause the air to rise and be recycled by the air supply  122  such that the air supply can provide more tempered air. Recycling the air in the enclosed space allows the drying space to maintain the consistent range of temperature needed for the plant material. 
     Referring now to  FIGS.  4 A and  4 B , the duct  400  having an elongated body, a duct open first end portion  410 , and duct closed second end portion  415  is shown, according to an example embodiment.  FIG.  4 A  is a bottom view of an elongated body  405  of a duct, according to an example embodiment.  FIG.  4 B  is a perspective view of the elongated body of the duct, according to an example embodiment. A first portion  430  plurality of openings is arranged in a first row  435  on a first side  440  of a vertical midline  445  of a traverse cross-section  450  of the duct; A second portion  455  of the plurality of openings is arranged in a second row  460  on a second side  465  of the vertical midline. Adjacent openings  420  of the plurality of openings of the first row are at least 14-20 inches spaced apart and wherein second adjacent openings of the plurality of openings of the second row are at least 14-20 inches spaced apart. Adjacent openings are those that are directly next to another opening relative to one side of the vertical line. 
     The duct open first end portion  410  allows the duct to receive a flow of tempered air from the air mover  135  supply vent such that the tempered air travels to the closed second end portion. The close second end portion causes air pressure to build up within the duct thereby forcing the tempered air to travel through the plurality of openings  420  and into the drying space  155 . 
     The vertical midline  445  represents a line that intersects the center point of the traverse cross-section of the duct and is perpendicular to the ceiling when the duct is in attachment with the air mover. The first side  440  includes the first portion  430  plurality of openings that are arranged in the first row  435 , which oriented in a horizontal line along the edge of the duct. The second row  460  of the second portion  455  plurality of openings are positioned at an angle from the vertical midline such that the second side looks mirrored to the first side. 
     The dimensions of the openings  420  and the spaces between the openings are configured to provide the drying space  155  with a flow of tempered air that is optimal for drying. These dimensions allow for the velocity of air flow to be fitting for the plant material in the drying space. The velocity includes a speed and direction that prevents direct airflow onto the plant material and into the ceiling and wall thereby preventing wind damage to the plant material and deadhead. The direction of the airflow must be angled 30 degrees below the plane of the ceiling to prevent deadhead. The velocity provides a drying space to surrounds the plant material with air that has adjusted temperature and humidity levels. The air&#39;s velocity and levels of humidity and temperature prevents the plants material from over drying and losing too much moisture. While an optimal amount of water weight for the plant material attributes, it is necessary for the plants to lose moisture in order to prevent pathogens and pests and also to maintain certain plant attributes such as color, texture, smell, and other certain attributes. 
     Referring now to  FIGS.  5 A and  5 B , cross-sectional views of the elongated body  405  of the duct  400  are shown, according to an example embodiment.  FIG.  5 A  a cross-sectional view of the elongated body of the duct, according to an example embodiment.  FIG.  5 B  is a cross-sectional view of the elongated body of the duct, according to an example embodiment. A first portion  430  plurality of openings is arranged in a first row  435  on a first side  440  of a vertical midline  445  of a traverse cross-section  450  of the duct. A second portion  455  of the plurality of openings is arranged in a second row  460  on a second side  465  of the vertical midline. The first row is disposed on a lower side  470  of the duct between 10 and 90 degrees from the vertical midline. 
     The first portion  430  of the plurality of openings is positioned at angle β from the vertical midline on the lower side of the duct. The second portion  455  of the plurality of openings is positioned at angle α from the vertical midline. Both angles are set to 60 degrees to position the first row and the second row at 4 o&#39;clock and 8 o&#39;clock on the traverse cross-section. These angles allow for airflow that moves way from the ceiling to prevent dead head. The angles flow the air downwards to create the drying space around the plant material and to prevent direct airflow onto the plant materials. The first row  435  and the second row  460  are arranged in horizontal lines parallel to each other to achieve even distribution of tempered air. 
     Adjacent openings of the plurality of openings  420  of the first row  435  are at least 14-20 inches spaced apart and wherein second adjacent openings of the plurality of openings of the second row  460  are at least 14-20 inches spaced apart. The diameter of each opening may be 2 inches. The spacings between adjacent holes and the diameters of each hole are configured to provide a strategically distributed flow of tempered air to the plant material. This flow of air will allow the plant material to receive a steady supply optimal temperatures and humidity levels such that the plant material is not overdried and maintains a healthy water weight. 
     Referring now to  FIG.  6   , a block diagram illustrating a method  600  of providing air flow to promote plant material drying and air purification is shown, according to an example embodiment. At step  605 A, the air supply  122  adjusts the temperature of the air and supplies that tempered air via air supply vent  125  into the enclosed space first portion. At step  605 B, the dehumidifier outlet  175  provides air with an adjusted level of water content into the enclosed space first portion. Both the air supply and the dehumidifier set the range of temperature and humidity levels needed in the drying space. The air mover  135  flows air into the duct at step  610 . The air mover inlet  140  receives the air from the enclosed spaced first portion such that a flow of air into the duct  400  is provided by the air mover outlet  145 . At step  615 , the elongated body  405  of the duct horizontally guides the tempered air. The flow of air from the air mover outlet travels from the duct open first end portion  410  to the duct closed second end portion  415 . After the increase in air pressure in the enclosed duct, the airflow is forced out of the plurality of openings  420  at step  620 . At step  625 , the airflow from the predefined pattern of the openings creates the drying space  155  around the plant material. The openings of the duct flow air out in two downward angles such that the airflow avoids hitting the wall and ceiling while preventing direct flow into the plants. The two angles allow the flow of air to surround the plant material without any damage or dead head. At step  630 A, the air return vent  130  retrieves air from the enclosed space first portion to be reused by the air supply. The air return sensor  165  helps the air supply determine the temperature of the provided air in step  605 A. At step  630 B, the dehumidifier inlet  170  receives air from the enclosed space for the dehumidifier to remove a certain amount of water from the air depending on the dehumidifier sensor  180 . It is understood that this method is a continuous cycle and that each step of method  600  may operate concurrently with another step of method  600  to provide a continuous movement and introduction of tempered and dehumidified air within the system. In other embodiments, the method may further include additional steps to promote plant drying or moisture removal consistent with the systems disclosed herein.
