- the valve 1010 is electrically connected to a clock 1014 which switches on dry air supply from the upstream components of the system 1000 at a predetermined time at or near sundown, and then switches to CO2 supply from the line 1012 at a predetermined time at or near dawn.
- the output 1016 of the valve 1010 is connected to a hoop house or the like.
- Humidity in greenhouses and hoop houses is a significant problem principally at night. Build up of high humidity levels in greenhouses and hoop houses routinely goes straight to 100% humidity at night, when the ventilation doors and windows are closed. This is due to the plants continued respiration of large amounts of water vapor. This nighttime buildup of humidity and moisture condensation, is directly responsible for resulting mold formation on the flower, which is an economic management problem for both cannabis growers and other crops grown in greenhouses. The presence of mold can render the harvest completely valueless.
- the current invention can be used at night, when it is not delivering the daytime CO 2 enrichment, to pump in pre-treated, dry air.
- a “cut-in” valve (allowing deactivated CO 2 supply to be isolated), air compressor and a dehumidifier are provided, providing for the input of ambient air that is dehumidified. This is a very efficient method as all existing field plumbing can be used to input the dry air.
- a very efficient air filter like a carbon filter is installed at the intake to remove unwanted airborne particulate and contaminants. These contaminants are removed as they can dog the emitters in the gas delivery system and can be damaging to the plants.
- the input air is passed through UV fungal spore killing lights to prevent the spread of undesirable pestilence within the grow space.
- the input air can have a thermal component added if desired.
- Odor from the production of cannabis particularly grown in older greenhouses, hoop house and outdoor production is a known public nuisance that is unresolved.
- Very stinky cannabis is most notorious as over night when build up occurs.
- the mitigation of odor from these sources is desirable. So the off-take of very humid air is also very stinky nuisance air, can take place on a hydraulically balanced line that sucks up (reverse arduous path emitter) located generally 1-3 feet distant to the input line with flow balanced to the desirable matching flow rates if necessary for pressure management desired in the structure.
- the sucking up and management of odor and humidity off-take can happen in conjunction with the dry air input.
- the two-line CO 2 system input described in the current embodiment could be used in this described methodology at night to achieve both humidity control and odor mitigation. Desirably to conserve energy the two air flows can pass across each other through an air-to-air heat exchanger to conserve energy.
- a pass-through enclosure with gaseous enrichment from the system can even be provided to suppress vector transmission as people, equipment and supplies enter and leave the production area.

The invention utilizes Carbon Dioxide gas (CO2 or CO2). The invention administers the gas in close proximity to plants growing in groups or plots so that the plants receive a maximum beneficial amount of the gas, for the longest reasonably possible time period. This also reduces cost to the grower. The system is able to maintain that close proximity distribution by various means including height adjustment means that permit the grower to easily adjust gas application height throughout the plant growth life cycle from seedlings or clones, juveniles, to mature plants ready for harvest. Further, the system permits fast and easy retraction at harvest time so that the gas distribution and application devices do not interfere with harvest tasks, whether manually or mechanized. The system is optimized to provide full monitoring and control of gas application, coordinated with light exposure, temperature regulation, watering, fertilizing and the like. The system may be integrated with lighting, heating, watering and feeding systems. Alternatively, it may be readily retrofitted to existing systems and devices.
- Referring to
FIGS. 1-5 , an embodiment of a system 10 of the invention is preferably a multi-stage system which basically comprises upstream and downstream stages or subsystems. Theupstream subsystem 12 shown inFIG. 5 receives and stores gas, particularly CO2gas. It also monitors the environment of the downstream subsystem, determines when and how to apply gas to plants growing in the downstream system, acquires gas stored in the upstream subsystem, and distributes it to the downstream system. It also has various monitoring, command and control, management, and reporting features. The downstream subsystem shown inFIGS. 14 comprises one or more plant growth areas or plots, gas distribution means, such as gas conduits, tubes or lines from the midstream subsystem, and the high efficiency, adjustable gas application means, and various sensing and monitoring means communicatively connected to the midstream subsystem. - In the system, the plant growth plot or plots are preferably relatively compact, sheltered environments such as hoop houses or greenhouses. Most particularly, the green houses are hoop-type houses that are easy to construct from basic materials such as dimensional lumber, PVC plastic conduit, lightweight but rigid metal tubing and the like for base structures. They typically have roofs or tops, most often constructed of transparent or semitransparent, thin, flexible plastic material. The plastic sheet or sheets are placed over and supported by hoop supports (typically curved to shed rain, wind, snow and the like) placed at predetermined distances apart, which are supported by the base structure. The sheets are typically stretched tight over the roof hoop supports to aid in shedding the elements, but also to reduce noise from flapping in the wind, and to improve structural integrity. Houses typically have side and end walls. Such walls may be adjusted or removed depending up temperature, climate and other factors. The walls are also typically constructed of flexible materials, most typically transparent or semitransparent materials. Hoop houses commonly are constructed on wade and have rectangular floor plans. Plants may be grown on grade, with existing soil (enhanced or not). The system may also be applied to houses constructed on slabs of concrete, asphalt or other non-soil substrates. Lastly the system may be deployed in existing interior structures such as permanent greenhouses, warehouses, and other structures. A preferred embodiment utilizes plant boxes constructed of dimensional lumber such as 2×12 s, and filled with a plant growth media composed of soil, and other materials beneficial to plant growth. Hoop houses may be provided with irrigation systems, light systems, heating systems, power, and the like. Although the invention is described in the context of a hoop houses, it is within the purview of the invention that the systems, apparatus and methods may be applicable to greenhouses or outside in fields, orchards, vineyards and the like.
- Referring to
FIG. 1 , the downstream subsection of the system 10 of the invention consists of multiple hoop houses 18 constituting a farm, with plural houses arranged in rows 20 A-C andcolumns 22 A-C, respectively, both shown started by their first members. Paths exist between rows 20 andcolumns 22 ofhouses 18 for convenient movement of staff, equipment, material and harvested crops. Referring also toFIGS. 24 , the hoop houses 18 have an elongated, rectangular configuration with first or proximal, and second ordistal end walls 90 and 94, respectively, and side waits 92 and 96. Walls 90-96 are supported bycorner posts 98A-D and a plurality of mid posts 100, the number of which depend upon the length of thehouse 18. The vertical walls 90-96 have a peripheraltop plate 102. Curved, roof hoops 104 extend from one side of theplate 102 to the other.Roof material 106 is supported by the hoops 104. Theroof 14 may be supported at its ends by one or more end supports 108. - The
exemplary houses 12 for growing cannabis have a length of approximately sixty (60) feet, a width of approximately fifteen (15) ft, and a height of approximately five (5) ft measured at the base wall and approximately nine (9) ft. at the apex of the hoop. In the preferred embodiment, the downstream stage or farm of hoop houses 12 is disposed within a fence or other security structure. Ingress and egress occurs though one or more gates. - The
upstream subsystem 12 is communicatively connected to the downstream subsystem via gas, electrical and data line conduits 24 and radio frequency (RF) and Wi-Fi wireless transmission. Gas is supplied toindividual plots 18A-C viaplot lines 28A-C. Gas may extend to plots disposed in columns behind afirst row 20A ofplots 18A-D via longitudinal feed lines, and then to further lateral trunks. Although the layout ofplots 18 in the downstream subsection have been shown rectilinearly, they may be disposed in various other linear or non-linear arrangements. Gas lines are preferably buried, but they may be disposed above grade. - A preferred embodiment of the
upstream subsection 12 is shown inFIG. 5 . Thesubsection 12 preferably comprises atank 40, a valve assembly, an electronic control assembly, and a power supply. Thetank 40 holds liquid Carbon Dioxide (CO2). It has a bulk storage capacity of between 5 and 50 Tons of liquefied CO2. It is within the purview of the invention that CO2 may be supplied in smaller quantiles such as 1,000-pound Dewars. And the system may be deployed in close proximity to a CO2 manufacturing facility (i.e., an ethanol, ammonia or power generating plant) and CO2 be directly derived therefrom. An exemplary tank is manufactured by Chart Industries of Prior Lake, Minn., USA. - The
tank 40 has a fill inlet 62. The tank is preferably also connected to a pressure builder which maintains the CO2 in a liquid form in thetank 40. An exemplary pressure builder is manufactured by Air Products of Allentown, Pa., USA. The vaporizer is also connected to thetank 40. It functions to convert CO2 from thetank 40 in a liquid state into a CO2 in a gas state for use in the system, CO2 gas exits an outlet at a pressure of between 200 and 400 psi., preferably 300 psi. An example vaporizer is available from Thermax of Dartmouth, Mass., USA. Theupstream subassembly 12 is preferably secured by its own security fence. - The upstream subsystem also comprises the valve assembly, electronic control assembly, RF and transmission and power supply. These components are preferably located in a secure housing. In the preferred embodiment, they are shown disposed in a
trailer 58. The valve assembly controls distribution of CO2 gas to the downstream system. The electronic control assembly is communicatively connected to the valve assembly and provides instructions to it, as to how to most efficiently distribute gas. The electronic control assembly is powered by power supply. The power supply preferably contains batteries and AC power connections. The upstream section also preferably has asolar array 56 for recharging the batteries of the power supply. The electronic control assembly preferably has both direct wire connections and wireless (WIFI, RF RF or the like) connections to various sensors (temperature, humidity, CO2 concentration, light intensity, wind speed, wind direction, and infrared leaf temperature readings that help determine VPD—vapor pressure deficit) disposed in the downstream section. The electronic control assembly also preferably has means to connect remotely via hardwire telephone, CDMA cell and/or satellite transmission. - Returning to
FIGS. 2-4 , the individual hoop houses 18 of the downstream section 16 include plural, for example three (3)beds 70A-C. The beds 70, preferably have an elongated, rectangular configuration, with proximal anddistal end walls side walls central planting area 80. Theplanting area 80 may utilize existing soils, on grade or built up, or preferably contains aparticular planting media 82. Thebeds 70 have a thickness or depth of between 6 and 18 inches, preferably about 10 in. when 2×12 dimensional lumber is used for the walls 72-78.Media 82 substantially tills theplanting area 80 to a depth of approximately 9 in. As is best shown inFIGS. 9 and 16 , once thebeds 70 are planted with seeds, seedlings, clones or othersmall plants 84, mulch (such as straw) may be applied to thebeds 70, covering theplanting area 80 between theindividual plants 84. A stabilizingmesh trellis blanket 118 may then be applied, covering theplanting area 80. Typically, multiple layers (for example four or more) of mesh are applied sequentially as the plants mature. Although the beds have been described as being constructed on the floor of a hoop house or the like, it is within the purview of the invention that the beds could be laid out on elevated tables or other elevated structures containing natural or artificial soils, or hydroponic liquid media, or trays, pots, soil containing bags or the like. - In the preferred embodiment shown, paths exist between beds for movement of staff, equipment, material and harvested crops. However, the intra bed paths are small and tight so that maximum space inside the house is devoted to plant growth. Because of this, applicants' invention has a means of maintaining clear paths or rendering them clear during maintenance or harvest. The exemplary bed for growing Cannabis has a length of approximately 58 feet, a width of 3 ft., and a bed height of about 1 ft. This yields a
planting area 80 of approximately 180 square feet. The intra-bod paths are approximately 18 in, wide. Ingress and egress occurs though one or both ends of the hoop house. - Each
bed 70 includes a gas emission assembly 109. Referring also toFIGS. 2 and 3 , one embodiment of the gas emission assembly 109 includes abed distribution manifold 130 and at least one gas emission line, tube orconduit 110. In the preferred embodiment, a pair oflines 110A-B is utilized. Thegas distribution manifold 130 is disposed at the first or proximal end of thebed 70, nearest the up andmidstream subsystems house 18 havingplural bed 70, themanifold 130 for each bed may receive gas from a hoop house distribution splitter or manifold 132 (connected to themain gas line 28A) viasupply lines 134.Lines 134 are preferably buried under the soil.Emission lines 110 are elongated and extend essentially the entire length of eachbed 70.Lines 110 A and B are disposed a predetermined distance apart preferably 12 in., the lines also being equally spaced from the sides of thebed 70. Thelines 110 are tubes having a central gas lumen and a plurality of emission apertures which emit CO2 gas to theplants 84. Thelines 110 are preferably constructed of a flexible plastic material and have an outside diameter of ⅝ in. The apertures are preferably circular and have a diameter of between ¼ to ¾ in. Thelines 110 are supported at each end byend posts 112 and 114. Theline 110 ends are connected to theposts 112 and 114 via at least onetension adjustment assembly 148 at eachline 110 end. Thetensioners 148 are preferably spring bias type tensioners and zip ties.Tensioners 148 may be disposed at only one, or both ends of eachline 110. The zip tie tensioners properly adjust the length and tension and the springs maintain the proper tension in the lines. In the embodiment ofFIG. 10 , thelines 110 are indirectly connected to theposts 112 and 114 vialateral members 142. Direction connection may be made in the alternative. Thelateral members 142 also can function to distribute and circulate gas. Theproximal member 142 is shown to be communicatively connected to the manifold 130 viagas line 140.Proximal member 142 is then connected to eachline 110A-B viaflexible lines 144 andcoupler assemblies 146. In view of the length and flexibility of theemission lines 110, at least one lateralmid-support assembly 106 is disposed along the length of thelines 110, typically at the mid or half way point of the length of thelines 110 generally at 20′ to 30′ intervals or such spacing necessary to prevent significant drooping in the lines and to prevent the lines from undesirable flapping in the wind. The lateral support preferably extends below and supports bothlines 110A-B for ease of adjustment. A CO2 gas line pressure sensor 156 is preferably connected in line with theassembly 130, preferably at the downstream end. This embodiment of theassembly 130 utilizes a continuous loop lumen from end to end, Alternatively, thegas lines 110 A/B may terminate at the distal end whereby all gas is emitted from the line apertures and does not circulate. - Significantly, the gas emission assemblies 109 are height adjustable so that the lines may be disposed and maintained within intimate proximity to the upper leafy canopy of the plants where sunlight is directly incident to said leaves and adjustable to the upper canopy of the
plants 84 as they grow. As the plants grow the lines can be slightly nested within'the canopy, but should never be disposed more than a few inches above the canopy due to loss of efficacy of the CO2 due to wind losses and diffusional forces losses known technically in physics and chemistry as Brownian Motion. The-lines 110 will be oriented just at the tops of the plants. - In the embodiment of
FIG. 6 , the height adjustment means 200 comprises avertical member 202, asleeve 204 adapted to be disposed around thevertical member 202, and a ratchet orpositioner assembly 206 coupled to thesleeve 204 and which selectively engages thevertical member 202. Thevertical member 202 is a studded T-Type post. Thesleeve 204 serves as a direct or indirect anchor or connection point for anemitter assembly 201. Theheight adjuster 200 permits adjustment of the position of theemitter 201 as one ormore plants 203 grow from a juvenile state (FIG. 6A ) to maturity (FIG. 6B ). Theheight adjuster 200 also permits complete removal of theemitter 201 during planting, installation of mesh trellis blankets and harvesting, by moving thesleeve 204 fully upward and over the top end of thevertical member 202, whereby thesleeve 204 and attachedemitter 201 are separated from thevertical member 202 and theemitter 201 may be moved freely away from the plant(s) 203 or earth. - As is best shown in
FIG. 5B , thevertical member 202 is an elongated post which has anaxial core 208 from whichribs 209A, B and C extend to yield a T shaped cross-section. The ribs 209 form first, second and third faces orsurfaces 210A, B and C, respectively. The faces 210 have a slight concave configuration. Studs orknobs 212 extend outwardly from thefirst face 210 A forming notches 214 between them. Rib 209C extends rearwardly from thefirst face 210A and separates second andthird faces 210B and C from each other. Each rib 209 extends radially from the center axis of thecore 208. Thestuds 212 have truncated, triangular configuration. They are spaced uniformly approximately 2.0 inches from each other (on center) yielding anotch 214 length of 1.25 inches. In this arrangement, the distance between the outward extending face of the rib 216 to the outward extending face of thestuds 212, or the effective maximum diameter “X” of thepost 202, is 1.25 inches. Thepost 202 is rigid and preferably constructed of a metallic material. Thepost 202 preferably has a bottom end which is driven into earth, soil or the like. At least onepost 202 is disposed at the end of eachplant bed 203 and serves as an support anchor for theemitter line 201.Post 202 has a preferred length or height of approximately six feet, but may have a length from four to eight feet to permit adjustable movement of theemitter line 201 as thecrop 203 below theemitter line 201 matures. - Referring also to
FIGS. 7A, 7B, 8A and B, thesleeve 204 has a tubular configuration with a central lumen 216 having an inside diameter sufficient to slidingly surround thepost 202, but still hold it closely to thepost 202. A preferred inside diameter for the lumen 216 is 1 15/16 inches for apost 202 having a maximum effective outside diameter “X” of 1¼ inches. However, the inside diameter of thesleeve 204 may vary. Thesleeve 204 has a preferred length of at least 24 inches, but it may be up to 36 inches. Theratchet positioner mechanism 206 facilitates a fast, easy to use, and secure means to raise and lower the height adjustment means 200. Theratchet mechanism 206 comprises abracket 218 and a spring clamp orbale 220. Thebracket 218 is formed of a rigid material such as galvanized steel. Thespring bale 220 is formed of a metallic material, preferably steel. Thebracket 218 has a generally rectilinear, U-Shaped configuration with three faces and an open end. Two opposing faces are fixedly coupled to the sleeve, near their outward ends, preferably by a pair of fasteners 224. The preferred dimensions of the bracket faces are 2⅜ inches (extending away from the sleeve) by 1½ inches (height) by 2⅜ inches (wide). This arrangement forms a solid base for mounting thespring clamp 220. Thebracket 218 is preferably connected to acoupler collar 228, but it may be connected directly to thesleeve 204, for example at its bottom end. Thecoupler 228 is a cylindrical member which is connected to thesleeve 204 and has an outside diameter which is slightly greater than that of thesleeve 204. Thespring clamp 220 comprises a first member 224 a, a second member 224 b, a third member 224 c, and a fourth member 224 d. These members are formed of a unitary piece of material, interconnected by 90 degree angle bends. The first member 224 a has afirst end 230 disposed inaperture 226A in face 222 b. It extends across a space or gap (preferably 2¼ inches inches) between faces 222 b and 222 a, through an aperture 226 b therein. Spring member 224 b is disposed outside of thebracket member 222A and bends to become spring member 224 c (with a bale width of preferably 2⅝ inches) spanning the gap between thefaces 222A and 222B, but entirely outside the space between those faces. Spring member 224 b bends to become final spring member 224 d which has a bendsecond end 232 that is embedded in aperture 226 c. - This
assembly 200 yields an easy to use ratchetingdevice 206 that makes a distinctive“clicking” sound as thesleeve 204 slides up the studs/notches 212/214 of thepost 202. Themechanism 206 yields a spring-loadedstop 220 that engages thestuds 212 of thepost 202. The mechanism 330 ratchets upwardly. It is releasable downwardly. As is best shown inFIGS. 7A and 7B , thesleeve 204 with a releasablyengageable positioner 218/220 has an engaged mode (FIG. 7A ) wherein thepost 202 is engaged to maintain the sleeve's height and prevents downward sliding of thesleeve 204 and allows thesleeve 204 to freely ratchet upwardly on thepost 202 incrementally. The releasably engageable positioner 218/220 can be disengaged (FIG. 7B ) to an open, nonengaging position enablingfree sleeve 204 sliding motion up and down the T-Post 202 and returned to a re-engagement. Thesleeve 204 supports at least one end of oneemitter line 201. As is best shown inFIGS. 8A and 8C , a pair ofscrews 234 secure faces 222 a and 222 b to thecoupler 228. Thescrews 234 are aligned so that their inward ends 236 are oriented along post faces 210 c and 210 b. This yields a narrowed positioning interlude that prevents thesleeve 204 from rotating around thepost 202, while at the same time, permitting thesleeve 204 to move freely vertically up and down thepost 202. Returning toFIG. 7 , thepositioner 218/220 is moved up and down by first flipping open thespring 220 to a non-engaging position, second, manually gasping thesleeve 204 and moving it into a desired position relative to thepost 202, and thirdly re-engaging thespring 220 with thepost 202. - Returning also to
FIGS. 2-4 , the method of constructing the height adjustable fluid distribution and emission assemblies (and for using such assemblies) for each bed is discussed. Posts are securely anchored into the ground or on the floor at each end of the beds. The posts are constructed and arranged such that they will not bend, even when inward pressure is applied to the top of the post. An emitter line (or simply emitter) is extended the length of the row and attached to the corresponding post at the far end of the bed. The emitter is preferably constructed of PLATIX tubing. In one alternative embodiment, the wire element is a self-supporting gas pipe. The emitter line is connected on each end to an adjustable sliding sleeve that can slide up or down on the post. The sleeve has the ability to lock or maintain to a fixed elevated position, that is height on the post, and is easily repositioned upwards or downwards to a new position as needed. The emitter line is tensioned gene ally tautly using any number of commercially available tensions like a ratchet strap, inducing minimal deflection down the length of the row from the far end post which also has the same slider arrangement. Cross members or aerial ties can be used intermittently down the row to support deflection in the emitter run as desired, for example a 3-20 foot spacing to create a scallop effect down the length of the row, but generally supporting the emitters at an equally desirable height at or just above the top of the plants from one end of the bed to the other. Another benefit of the height adjustment assembly is that it can be constructed either on-site or pre-made and delivered to the site. - As shown for example in
FIG. 6 , emitters are positioned intimately proximate to the upper leafy canopy of the crop where sunlight is predominately incident. As the crop 48 continuously grows, the sliders at each end are moved up the posts incrementally as needed to accommodate plant growth and to stay above of the introduction of the latest applied mesh trellis in the bed as is commonly known and used in the cultivation of cannabis or other such crops. Upward mobility of the device is permitted to correspond to plant growth. They may be removed or moved out of the way to facilitate harvest and other agronomic functions like the introduction of mesh. - The height adjustment assembly, including the releasably engageable positioner, sleeve, and post, can also be employed independently for other purposes like maintaining variable sign height, wind foils height (such as those disclosed in U.S. Pat. No. 10,165,73X) for Aerial Saplings, snow fences, ski area boundaries, farm fences, and the like.

FIGS. 10 A and B show an embodiment of an offset weighted foot and legheight adjustment system 400 of the invention that allowsline 402 tensioning, without drivingposts 404 into ground or a floor 406. This feature is beneficial for installation into greenhouse that have cement floors 406 or the like whereposts 404 cannot be readily driven into the ground. Thesystem 400 includes afoot 408 which serves as a base for thepost 404. Thefeet 408 are have a base 410 having aholder 412 disposed proximate an end of the base 410 which is disposed proximate one end of thebase 410. The majority of thebase 410 is disposed away from that end and is deployed, in use, under tables 414 which holdcrop 416. Again,height adjustment mechanisms 418 are part of theposts 404 and permit arrangement of theemitter lines 402 immediately abovemesh panels 420. -
FIG. 11A shows a further embodiment of the gas miner line andsupport system 500 of the invention for multiple introduction of a variety of gaseous media for micro-climate control inputs with a variety of flow rates and timing, and lines for vacuum intake of micro-climate including but not limited to odor reduction and humidity reduction.Multiple lines 502A-D are deployed by eachheight adjustment mechanism 504. Thelines 502 function forhumidity control 502A,odor control 502B, temperature control 5030, andCO2 enrichment 502D. The post and sleeve assembly can accommodate multiple lines of conductance for a variety of liquids, gases, aerosols, volumes and flow rates for a variety of micro-management objectives of the leafy canopy throughout a growth cycle. The additional lines of gaseous conductance can include thermally treated air, either heated in the colder late fall, winter and early spring months or cooled air during the summer drawn across an ambient vaporizer present, dried air to reduce humidity, micro-aerosol nutrients, flowering inducement, and reverse flow direction intake—for—odor control, humidity control and desirable micro-climate environmental practices. Curtains can be provided between the rows of the system, to isolate vectoring and maintain a variety of gaseous mixtures between adjacent rows. Referring toFIG. 11B ,odor control line 502B is fluidically connected tocontroller 506, which is connected to vacuum 508, which is connected to filter 510, which is finally connected togas output 512. -
FIGS. 12 and 13A show an embodiment of a single post cross overmanifold system 600 of the invention, that provide more than one attachment point to the vertical post. It further provides lateral supports that extend outwardly and are attached near the ends of the end support bars, thus relieving torsion across the end support bar exerted by the tensioning of the emitter lines. The advantage of this innovation is it requires only one post and sleeve assembly per bed-end, for a total of only two per bed. The single post cross overmanifold 600 for controlling gas emission receives gas from a bed distribution manifold (not shown) or from a direct gas supply line atinput connector 602. Thegas distribution manifold 600 is disposed at the first or proximal end of the bed. Referring also again toFIGS. 2-4 , forhouse 18 havingplural beds 70, the manifold 130/600 for eachbed 70 may receive gas from a hoop house distribution splitter or manifold 132 (connected to themain gas line 28A) vi a supply lines 134.Lines 134 are preferably buried under the soil.Emission lines 110 are elongated and extend essentially the entire length of eachbed 70.Lines 110 A and B are disposed a predetermined distance apart, preferably 12 in., the lines also being equally spaced from the sides of thebed 70. Thelines 110 are tubes having a central gas lumen and a plurality of emission apertures which emit CO2 gas to theplants 84. Thelines 110 are preferably constructed of a flexible plastic material and have an outside diameter of ⅝ in. The apertures are preferably circular and have a diameter of between 114 to ¾ in. Thelines 110 are supported at each end by thesingle end post 112 viaheight adjustment sleeve 113. Theline 110 ends are connected to thesleeve 113 via at least onetension adjustment assembly 148 at eachline 110 end. Thetensioners 148 are preferably spring bias type tensioners. Thetensioners 148 are slidably connected to lateral gas transfer andsupport member 142 byslide couplers 604. These enable bed width adjustment. Thelateral member 142 is also stabilized bysupport arms 606 viaconnectors 608 which are slidable about the length of thearms 606 and are thither rotatable about 2 axis. Thesupport arms 606 are connected at their proximal ends viacoupler 610 tosleeve 113. Lastly, thelateral arm 142 is coupled (rotatable about one axis) to the sleeve at it's midpoint viacoupler 612. - In view of the length and flexibility of the
emission lines 110, at least one lateral mid support assembly may be disposed along the length of thelines 110, typically at the mid or half way point of the length of thelines 110. The lateral support preferably extends below and supports bothlines 110A-B for ease of adjustment. A CO2 gas line pressure sensor is preferably connected in line with theassembly 130, preferably at the downstream end. This embodiment of theassembly 600 utilizes a continuous loop lumen from end to end. Alternatively, thegas lines 110 A/B may terminate at the distal end, whereby all gas is emitted from the line apertures and does not circulate. - Importantly, the
gas emission assemblies 600 are height adjustable so that the lines may be disposed close the plants as they grow. Thelines 110 are preferably oriented just above the tops of the plants. In the preferred embodiment the height adjustment means is theadjustable sleeve 113 with ratchet mechanism 115. This permit adjustment of the entire gas line assembly either flat (as shown) or tilted, during height adjustment. This is beneficial when plants grow disproportionally in thebeds 70. -
FIG. 14 shows another embodiment of an adjustable, universal,distal end manifold 700, which is adjustable when the width of the bed is X, the width of the elongated emitter lines is set at ¼X from either side of the bed, with line width not to exceed 3′ between inner bed spacing. This manifold 700 is disposed at the distal end. of each bed 70 (the end opposite the gas supply manifold 600). - The
distal end manifold 700 includes a pair ofheight adjustment sleeves 702, a lateral support and gas supply member 704, and flexible,adjustable gas connectors 706 which are connected to emitter lines 110. The support and supply member 704 is coupled to theheight adjustment sleeves 702 bycouplers 708. Theflexible gas connectors 706 are adjustable, forbed 70 width, byslide couplers 710. -
FIGS. 15A and B illustrate an embodiment of a gas control,system 800 of the invention that adjusts gas application relative to wind direction and magnitude. The allocation of gas goes towards the upwind line. Thesystem 800 includes a pair of emitter lines 802 A and B coupled to height adjustable line support and gas supply ends 804A and B. - The system of the invention can be extended to the control of pests such as mites. For any of the following a technician is present desirably a skilled and trained person that is a Pest Management Agent. The infested plants can be tented with a sealed plastic fabric cover. All people and mammals are directed to exit the enclosures and it is double checked to make sure it is “All Clear!” Then the CO2 gas is introduced for a period to organically kill most all of the pests on the plants without damaging the plants themselves. It is anticipated that there is wide variation between plants and pests as to toxic levels of gas exposure and the exposure level and duration is specific to the non-phytotoxicity to the host plant species and its maturity, and the lethal level of toxicity for the targeted pest species and its life cycle including eggs.
- It is anticipated that a variety of mixtures of gas can be used to accomplish, the desired outcome of non-toxic affect to the host plants and lethal affect to the pest and eggs. The level of gas(s) and duration of application is determined by two variables, determining the non-phytotoxicity to the host plants/targeted crop, and determining the lethal level and duration required to kill the targeted pest and desirably their eggs.
- Multiple plants in that garden can be tented at once and a whole group can be cleansed of pest at once either through a single tent or multiple tents. For cannabis, certain enclosures can have the gas shutoff to concentrate the flow of gas in one or more enclosures for 90 minutes, allowing the gas flow through the system without the system freezing-up through the for nation of dry ice or the likes, thus restricting the necessary flow to achieve and maintain pest lethal levels in the targeted enclosures. If necessary additional valves can be opened in the target enclosures to achieve more rapid gaseous flow rates to attain the lethal levels desired. At the end of the duration, the room is enclosure ventilated either with fans or doors and sidewalk are reopened, the elevated gas is allowed to escape and returned to normal—safe ambient levels, and workers can safely return into the space. This process can be repeated after several days to target any eggs that hatch and reduce any resurgence of pests.
- In a preferred embodiment a single pest control enclosure is established at the farm for passing new plants clones through a cleansing process, that are coming into the farm. The clones are given a CO2 bath or other gaseous media to reduce the pest count and eggs of pest present on the new plants coming from a remote source.
- It is envisioned by the invention that the liquefied gas tank, vaporizer, electronic controllers, sensor, clock and delivery pipes can be in a fully mobilized and contained unit. The unit can travel from farm to farm and provide gaseous pest control, on an as needed basis, following the same protocol as described above.

FIGS. 6-18 show a third embodiment of a pest control system, namely a fixed basepest control system 900. It comprises abuilding 902 which is disposed along a transportation corridor (for example a highway, road, street or the like) for routine shipments of clones/saplings/cultivars or the like (baby plants for transplanting) being transported from a remote production nursery, into a production region. Thebuilding 902 is preferably designed similar to a carwash, in that atruck 904, van, or lorry can drive in and out of one ormore enclosures 906 of thebuilding 902. Once thevehicle 904 transporting the clones is within the enclosure, both building ingress andegress doors 908 A and B are tightly sealed. The vehicle's 904cargo bay doors 910 are fully opened up, so that the gas fromsupply 912 provided throughinput mechanism 914 has free and unencumbered access to all of the clones. All people and animals exit theenclosure 906. The gas is then elevated within the enclosure to a lethal level as determined bysensor 916 for pests for the necessary duration as determined byclock 918. At the end of the duration, the enclosure doors 908 are reopened, the elevated gas is allowed to escape and returned to normal—safe ambient levels. The truck driver can re-enter the area to reseal hisvehicle 904cargo bay doors 910, can get back M thevehicle 904 and drive away to his destination farm for delivery of the now pest cleansed baby transplants. Thebuilding 902 is immediately ready to receive a next vehicle for processing. - A final version is to set up the clone cleansing enclosure and facility right at the production center of the clones and pass the clones through the pest control process just before they are loaded into the trucks for shipment to remote farms.
- Any of the above embodiments the procedure can be done in the dark when the plants are not undergoing photosynthesis.

FIG. 19 is a diagram of an embodiment of ahumidity control system 1000 for hoop houses of the present invention. Thesystem 1000 includes anair intake 1002, anair filter 1004 fluidly connected to theinput 1002, acompressor 1006 connected to an output of thefilter 1004, aUV sterilizer 1008 connected to the output of thecompressor 1006, and a cut invalve 1010 connected to the output of the sterilizer and to a CO2gas input line 1012. Thevalve 1010 is electrically connected to aclock 1014 which switches on dry air supply from the upstream components of thesystem 1000 at a predetermined time at or near sundown, and then switches to CO2 supply from theline 1012 at a predetermined time at or near dawn. Theoutput 1016 of thevalve 1010 is connected to a hoop house or the like. Humidity in greenhouses and hoop houses is a significant problem principally at night. Build up of high humidity levels in greenhouses and hoop houses routinely goes straight to 100% humidity at night, when the ventilation doors and windows are closed. This is due to the plants continued respiration of large amounts of water vapor. This nighttime buildup of humidity and moisture condensation, is directly responsible for resulting mold formation on the flower, which is an economic management problem for both cannabis growers and other crops grown in greenhouses. The presence of mold can render the harvest completely valueless. - Therefore, it is envisioned that the current invention can be used at night, when it is not delivering the daytime CO2 enrichment, to pump in pre-treated, dry air. A “cut-in” valve (allowing deactivated CO2 supply to be isolated), air compressor and a dehumidifier are provided, providing for the input of ambient air that is dehumidified. This is a very efficient method as all existing field plumbing can be used to input the dry air.
- Desirably a very efficient air filter like a carbon filter is installed at the intake to remove unwanted airborne particulate and contaminants. These contaminants are removed as they can dog the emitters in the gas delivery system and can be damaging to the plants. Also, desirably the input air is passed through UV fungal spore killing lights to prevent the spread of undesirable pestilence within the grow space. Also, the input air can have a thermal component added if desired.
- Odor from the production of cannabis particularly grown in older greenhouses, hoop house and outdoor production is a known public nuisance that is unresolved. Very stinky cannabis is most notorious as over night when build up occurs. The mitigation of odor from these sources is desirable. So the off-take of very humid air is also very stinky nuisance air, can take place on a hydraulically balanced line that sucks up (reverse arduous path emitter) located generally 1-3 feet distant to the input line with flow balanced to the desirable matching flow rates if necessary for pressure management desired in the structure. The sucking up and management of odor and humidity off-take can happen in conjunction with the dry air input.
- It is even envisioned that the two-line CO2 system input described in the current embodiment, could be used in this described methodology at night to achieve both humidity control and odor mitigation. Desirably to conserve energy the two air flows can pass across each other through an air-to-air heat exchanger to conserve energy.
- Further, a pass-through enclosure with gaseous enrichment from the system can even be provided to suppress vector transmission as people, equipment and supplies enter and leave the production area.
