The prescribed conveying path is described by at least one conveying chain guide rail 24, 25 which is bolted to and supported by one side of the conveying frame 1 relative to the X-Axis of the prescribed conveying path, the at least one conveying chain guide rail 24, 25 guide and support, in conjunction with at least one conveying chain drive sprocket 3 which is driven by and mounted to and supported by a drive shaft 4 which is driven by and mounted to and supported by to a conveying chain drive motor/gearbox 5 see FIG. 1, FIG. 2, FIG. 10, and FIG. 27 which is supported by and bolted to a motor/gearbox 5 supporting mechanism which is bolted to and supported by one side of the conveying frame 1 relative to the X-Axis of the prescribed conveying path, and in conjunction with a plurality of idler sprocket 32 mechanisms see FIG. 11, and FIG. 27 which are supported by and bolted to the conveying frame 1, at least one conveying chain 26 as it is recirculated around the prescribed conveying path relative to the X-Axis of the prescribed conveying path. The at least one conveying chain 26 is connected to an absolute position encoder which provides absolute conveying chain 26 position feedback to the PLC. The conveying chain 26 links possess bearings that contact the at least one conveying chain guide rail 24, 25 guide surfaces to reduce friction when the at least one conveying chain 26 is recirculated around the prescribed conveying path, at least one take-up adjustment mechanism will be required for the conveying chain 26 it is not defined herein. The conveying chain 26 links are manufactured with spigot pins 155. The conveying chain motor 5 is powered by a variable frequency drive controlled by the PLC which allows recirculation speed and direction change to by affected on the conveying chain 26.

[0216] In another embodiment the conveying chain 26 is replaced by a conveying drive belt and the conveyor drive assembly and the conveying tray locking mechanism are modified accordingly.

[0217] In another embodiment the conveying chain 26 is replaced by a conveying cable and the conveyor drive assembly and the conveying tray locking mechanism are modified accordingly.

[0218] In another embodiment the prescribed conveying path is generally oriented along the Y-Axis of the conveying frame.

[0219] In another embodiment the prescribed conveying path form is a multiple tiered arrangement see FIG. 45 and requires internal 180 degree conveying chain guide rails see FIG. 45 to define the prescribed conveying path, the conveying chains for the internal 180 degree conveying chain guide rails must be disconnected from the conveying chains running around the remainder of the prescribed conveying path, the internal 180 degree conveying chains must run at a higher speed than the chains running around the rest of the prescribed conveying path to allow adequate spacing for the plants in the tightened radius.

[0220] In another embodiment the prescribed conveying path form is substantially altered to allow the at least one conveying tray assembly 2 to remain upright as it recirculates around the prescribed conveying path, the conveying tray assembly 2 is decoupled from its two tray chain locking mechanisms relative to the Z-Axis of the prescribed conveying path, the conveying tray assembly 2 has two swivel mechanisms one swivel mechanisms mounted on each side of the conveying tray assembly 2 relative to the Z-Axis of the prescribed conveying path, each swivel mechanisms has a chain locking mechanism mounted to it the tray chain locking mechanisms the conveying tray assembly 2 to rotate about its Z-Axis, a cam follower is attached to one side of the conveying tray assembly 2, the plurality of conveying chain guide rails 24, 25 are modified a have an alignment cam profile machined into them 2 relative to the X-Axis of the prescribed conveying path, the cam follower makes continuous contact with the alignment cam profile machined into the plurality of conveying chain guide rails 24, 25 as the conveying tray assembly 2 recirculates around the prescribed conveying path, the cam follower is pushed by the alignment cam profile machined into the plurality of conveying chain guide rails 24, 25 and this compels the at least one conveying tray assembly 2 Z-Axis to remain perpendicular to the conveying frames 1 X-Axis as it recirculates around the conveying pat, the plant stems constrained within the at least one conveying tray assembly 2 therefore remain perpendicular to the conveying frames 1 X-Axis as they recirculated around the prescribed conveying path in the natural orientation of all growing plants.

[0221] A plurality of conveying tray assemblies 2 maybe be locked onto the conveying chains 26 at variable offset distances relative to the X-Axis of the prescribed conveying path between the conveying tray assemblies 2 depending on the surface area requirements of the plants at all stages of their life cycle. FIG. 2 shows the conveying tray assemblies 2 offset six inches from each other thus twelve inches exists between plant stems relative to the X-Axis of the prescribed conveying path. If the conveying tray assemblies 2 are locked on the conveying chains 26 with no gap between the offset distance is zero inches and there exists 6 inches between the plants stems relative to the X-Axis of the prescribed conveying path Two conveying tray locking mechanisms 70,71 and 72 see FIG. 8, FIG. 9, FIG. 36, and FIG. 37 are mounted one on either side of the conveying tray assembly's 2 double skin tray 65 relative to the L-Axis of the prescribed conveying path to nodes on the underside of the conveying tray assembly's 2 double skin tray 65 see FIG. 8, FIG. 9 and FIG. 36. The two tray locking mechanisms are identical and are assembled as follows; the tray chain lock 70 see FIG. 8, FIG. 9, FIG. 36 and FIG. 37 is mounted on two tray chain lock sliders 72 see FIG. 8, FIG. 9, FIG. 36. The two tray chain lock sliders 72 are inserted through the two tray lock slider penetrations 157 see FIG. 37 machined into the tray chain lock 70 see FIG. 8, FIG. 9 and FIG. 36. A tray chain locking spring 71 is also mounted onto each tray chain lock slider 72 see FIG. 8, FIG. 9, FIG. 36. The two tray chain lock sliders 72 are inserted through the penetrations machined in the nodes on the underside of the conveying tray assembly's 2 double skin tray 65 see FIG. 8, FIG. 9 and FIG. 36. The two tray chain lock sliders 72 are locked to the nodes relative to the Z-Axis of the prescribed conveying path causing the tray chain lock 70 and the two tray chain locking springs 71 to also be locked in place. The two tray locking mechanisms are operable as follows; the two tray chain locking springs 71 push against the inside face see FIG. 37 of the tray chain lock 70 which is free to slide on the two tray chain lock sliders 72 relative to the Z-Axis of the prescribed conveying path causing the tray chain lock 70 to move to its locked position relative to the Z-Axis of the prescribed conveying path. An external force pushing against the outside face see FIG. 37 of the tray chain lock 70 relative to the Z-Axis of the prescribed conveying path in the opposite direction to the force applied by the two tray chain locking springs 71 is required to cause the tray chain lock 70 to move to its unlock position, the tray chain lock 70 has a push latch mechanism similar to that of a retractable pen not shown herein that keeps the tray chain lock 70 in the unlocked position until it is pushed on again at which point the push latch mechanism is released and when the pushing force is removed the tray chain lock 70 is then moved to the locked position by the two tray chain locking springs 71. Two tray chain locking spigot pin penetrations 156 see FIG. 37 are also machined into the tray chain lock 70 see FIG. 8, FIG. 9, FIG. 36 and FIG. 37. When the two conveying tray locking mechanisms mounted at either side of a conveying tray assembly's 2 double skin tray 65 are in the locked position, the distance between the outside faces see FIG. 37 of the tray chain locks 70 relative to the Z-Axis of the prescribed conveying path is equal to Distance L see FIG. 31 which is the distance between the conveyor chains 26 inner link faces across the conveyor drive assembly Distance L see FIG. 31 relative to the Z-Axis of the prescribed conveying path. When the two conveying tray locking mechanisms mounted at either side of a conveying tray assembly's 2 double skin tray 65 are in the unlocked position, the distance between the outside faces see FIG. 37 of the tray chain locks 70 relative to the Z-Axis of the prescribed conveying path is less than Distance S see FIG. 31 which is the distance between the conveyor chains 26 inner conveyor chain locking spigot pin faces across the conveyor drive assembly Distance L see FIG. 31 relative to the Z-Axis of the prescribed conveying path. The two conveying tray locking mechanisms mounted at either side of a conveying tray assembly's 2 double skin tray 65 in conjunction with the conveying chains locking spigot pins are operable as follows an external force pushing against the tray chain lock's 70 outer face in the opposite direction to the force applied by the two tray chain locking springs 71 is applied to both tray chain locks causing both the tray chain locks 70 to move to their unlocked positions the conveying tray assembly 2 now be inserted into the conveyor drive assembly 128 relative to the Z-Axis of the prescribed conveying path, if the two tray chain lock's 70 two tray chain locking spigot pin penetrations 156 mounted at either side of the conveying tray assembly's 2 double skin tray 65 are aligned with the same relative conveying chain 26 link's two conveying chain locking spigot pins on the two conveying chains 26 the external force can be removed from the outside faces of the two chain locks 70 mounted at either side of a conveying tray assembly's 2 double skin tray 65 and the two tray chain locking springs 71 mounted at either side of the conveying tray assembly's 2 double skin tray 65 will move the two tray chain locks 70 mounted at either side of a conveying tray assembly's 2 double skin tray 65 to their locked positions capturing the same relative conveying chain 26 link's two conveying chain locking spigot pins on the two conveying chains with the two tray chain locking spigot pin penetrations 156 machined into the tray two chain locks 70. The conveying tray assembly 2 is now locked onto the conveyor drive assembly.

The plurality of media holder assemblies #1 to #6 78 to 83 are component parts of the media holders position adjustment assembly 129 see FIG. 28. The plurality of media holder assemblies #1 to #6 78 to 83 are constrained in the slot machined into the conveying tray assembly's 2 double skin tray 65 relative to the Z-Axis of the prescribed conveying path. The offset distance between the plurality of media holder assemblies #1 to #6 78 to 83 can be adjusted relative to the Z-Axis of the prescribed conveying path if the conveying tray assembly 2 is aligned with media holders drive assembly 124 see FIG. 1, FIG. 2, and FIG. 21 relative to the X-Axis of the prescribed conveying path and if the conveying tray media holders drive stepper motor assembly 10 is in the couple position, the offset distance between media holder assemblies #1 to #6 78 to 83 can be adjusted from zero to six inches thus the distance between plant stems can be adjusted between six inches to 12 inches relative to the Z-Axis of the prescribed conveying path. Media holder assembly #1 78 is locked to the double skin tray 65 and the media holder assemblies #2 to #6 79 to 83 are free to move relative to media holder assembly #1 78 linearly relative to the Z-Axis of the prescribed conveying path. The media holder component 15 has a media holder drive housing 134 machined into its base see FIG. 29 a media holder drive housing gear slot 135 is machined into media holder component's 15 drive housing 134, a right lead screw threaded penetration 131 is machined into the media holder component's drive housing 134, the portion of the lead screw threaded penetration 131 through which the media holder lead screw 77 is fitted and locked into the media holders lead screw gear 116 is drilled out to provide a smooth bore within which the media holder lead screw 77 can rotate freely, and a smooth bore penetration 132 is machined into the media holder component's 15 drive housing 134 through which the media holders splined drive shaft 75 is passed and in which the media holders splined drive shaft 75 is free to rotate, the media holders splined drive shaft 75 also passes through, but is not locked to the media holders splined drive gear 117 which is located in the media holder drive housing gear slot 135, the media holders lead screw gear 116 and the media holders splined drive gear 117 are now meshed and rotate together. The media holder lead screw 77 of media holder assembly #1 78 is threaded into the lead screw threaded penetration 131 of media holder #2 79. The media holder lead screw 77 of media holder assembly #2 79 is threaded into the lead screw threaded penetration 131 of media holder #3 80. The media holder lead screw 77 of media holder assembly #3 80 is threaded into the lead screw threaded penetration 131 of media holder assembly #4 81.

Media holder #6 82 does not require a media holder lead screw. 77 nor a media holder splined drive gear 117 nor a media holder lead screw gear 116. The media holders splined drive shaft 75 is inserted through the media holder drive shaft smooth bore penetration 132 of each media holder assembly #1 to #6 78 to 83 and through the media holders splined drive gears 117 which are housed in the media holder drive housing gear slot 135 of each media holder assembly #1 to #6 78 to 83. The media holders splined drive shaft 75 is locked relative to the Z-Axis of the prescribed conveying path but free to rotate in the smooth bore penetration 132 machined into the media holder component's 15 drive housing 134. A media holders splined drive coupling gear 76 is fixed to the end of the media holders splined drive shaft 75 protruding from the smooth bore penetration 132 of media holder assembly #1 78. Rotating the media holders splined drive coupling gear 76 causes the media holders splined drive shaft 75 to rotate within the smooth bore penetrations 132 machined into the media holder component's 15 drive housing 134 which causes the plurality media holder assemblies splined drive gears 117 to rotate which causes their meshed counterpart plurality of media holders lead screw gears 116 to rotate which causes the plurality of media holder lead screws 77 to rotate. The media holders position adjustment assembly 129 is operable as follows see FIG. 8, FIG. 21, FIG. 28, and FIG. 29, if the conveying tray assembly 2 is aligned with media holders drive assembly 124 see FIG. 2, relative to the X-Axis of the prescribed conveying path and if the conveying tray media holders drive stepper motor assembly 10 is moved to the couple position by the conveying tray media holder drive stepper motor engagement actuator assembly 11 so that the conveying tray media holders drive gear 137 is meshed with the media holders drive coupling gear 76, the conveying tray media holders drive stepper motor 136 can be rotated under PLC control.

[0228] The recirculating plant growing mechanism may have at least one LED light bar cleaning tray assembly 21. If an LED light bar cleaning tray assembly 21 is to be used in the recirculating plant growing mechanism the conveying drive assembly's 128 maximum capacity of conveying tray assemblies 2 is reduced by one to leave space on the conveying chains 26 for the LED light bar cleaning tray assembly 21. In this embodiment the PLC will automatically store the LED light bar cleaning tray assembly 21 in the airlock transfer assembly 126 see FIG. 26 when the LED light bar cleaning tray assembly 21 not in use, and when the airlock transfer assembly 126 is not required for other duties, clamped in the tray clamp carriage 20 see FIG. 1 and FIG. 24 that are mounted on the airlock transfer assembly's 127 see FIG. 1, FIG. 2, FIG. 24 and FIG. 26 air lock transfer actuators 14 see FIG. 1, FIG. 2, FIG. 23, FIG. 24 and FIG. 26, when the airlock transfer assembly 126 is required for other duties or when LED light bar cleaning is desired the PLC will automatically lock the LED light bar cleaning tray assembly 21 onto the conveyor drive assembly's 128 two conveying chains 26 in the location reserved for it in the same manner that has be described above and below for a conveying tray assembly 2. The LED light bar cleaning tray assembly's 21 base has the same type of two conveying tray locking mechanisms as the conveying tray assembly 2 that are mounted in the same manner and relative positions as the two conveying tray assembly's 2 locking mechanisms mounted on either side of a conveying tray assembly's 2 double skin tray 65, the tray chain locks 70 have a push latch mechanism similar to that of a retractable pen not shown herein that keep the tray chain locks 70 in the unlocked position until it is pushed on again at which point the push latch mechanism is released and when the pushing force is removed the tray chain lock 70 is then moved to the locked position by the two tray chain locking springs 71. The LED light bar cleaning tray assembly 21 can therefore be locked onto the conveyor drive assembly's 128 two conveying chains 26 in the same manner as has be described above and below for a conveying tray assembly 2. When an LED light bar cleaning tray assembly 21 is locked on the conveying chains 26 it can be recirculated around the prescribed conveying path in the same manner as has been as has already been described above for a conveying tray assembly 2. The LED light bar cleaning tray assembly 21 has a cleaning tray cleaning solution pressure bladder tank 114 see FIG. 4, FIG. 5, FIG. 6, and FIG. 38 in place of a conveying tray assembly's 2 double skin tray 65. The cleaning tray cleaning solution pressure bladder tank 114 has the same dimensions as a double skin tray 65 relative to the X-Axis and Z-Axis of the prescribed conveying path. The cleaning tray cleaning solution pressure bladder tank 114 has a slightly taller dimension than a double skin tray 65 relative to the Y-Axis prescribed conveying path to provide more cleaning solution capacity. The cleaning tray cleaning solution pressure bladder tank 114 has an inlet cleaning solution coupler with non-return valve 158 see FIG. 5, FIG. 6, and FIG. 38 mounted on and ported into the base of the cleaning tray cleaning solution pressure bladder tank 114.

The LED light bar cleaning tray assembly 21 has two cleaning head mechanisms see FIG. 4, FIG. 5, FIG. 6, and FIG. 38 mounted in mirror image of each in recesses see FIG. 4, FIG. 5, and FIG. 38 cut into the cleaning tray cleaning solution pressure bladder tank 114 at either end relative to the Z-Axis of the prescribed conveying path. Two threaded penetrations, the penetrations are not shown herein, are machined into the front face of the recesses FIG. 4 cut into the cleaning tray cleaning solution pressure bladder tank 114 at either end relative to the Z-Axis of the prescribed conveying path. The two cleaning head mechanisms are assembled in the same manner. An LED light bar cleaning sponge 34 is mounted to the front face see FIG. 4 of the cleaning tray mount 110 see FIG. 4, FIG. 5, FIG. 6, and FIG. 38. An LED light bar cleaning squeegee 35 is mounted to the front face of the cleaning tray mount 110 see FIG. 4, FIG. 5, FIG. 6, and FIG. 38. The cleaning tray mount 110 has a penetration machined into the front and rear face of the cleaning tray mount 110, relative to the Z-Axis of the prescribed conveying path the penetration is aligned with the center point of the LED light bar cleaning sponge 34 relative to the X-Axis and Y-Axis of the prescribed conveying path the penetration is not shown herein, that allows the cleaning tray mount cleaning solution delivery tube 15 see FIG. 4, FIG. 5, and FIG. 38 to pass through the cleaning tray mount 110. The cleaning tray mount cleaning solution delivery tube 15 is attached and sealed to the penetration through the front face of the cleaning tray mount 110. A penetration is machined into the front face of the recesses cut into the cleaning tray cleaning solution pressure bladder tank 114 the penetration is not shown herein, an O-ring seal is installed in the penetration that allows the fully retracted position to pass through the O-ring seal and into the cleaning solution pressure bladder tank 114. The cleaning tray mount cleaning solution delivery tube 15 penetrates the cleaning tray cleaning solution pressure bladder tank 114 and couples with a mechanically operable valve not described herein which when closed prevents the pressurized cleaning solution from entering the cleaning tray mount cleaning solution delivery tube 15, the mechanically operable valve is only opened when the cleaning tray mount 110 is in the fully retracted position causing the cleaning tray mount cleaning solution delivery tube 15 to open the mechanically operable valve allowing cleaning solution to flow through the cleaning tray mount cleaning solution delivery tube 15 soaking the LED light bar cleaning sponge 34 with fresh cleaning solution. The cleaning tray mount 110 has two penetrations machined into the rear face of the cleaning tray mount 110, the penetrations are not shown herein, that allow the two cleaning tray mount sliders 112 see FIG. 4, to be insert FIG. 5, FIG. 6, and FIG. 38 relative to the Z-Axis of the prescribed conveying path. The cleaning tray mounts 110 two penetrations are aligned with the two threaded penetrations that are machined into the front face of the recesses cut into the cleaning tray cleaning solution pressure bladder tank 114. The two cleaning tray mount sliders 112 are threaded at both ends. The two cleaning tray mount stops 160 see FIG. 4 have partial threaded penetrations machined in to them.

The cleaning tray mount springs are now pushing against the rear face of the cleaning tray mount 110 holding the mount in the fully extended position. When. LED light bar 6 see FIG. 15 cleaning is desired in this embodiment each group of six LED light bars 6 mounted on each groups two LED light bar track assemblies 7 see FIG. 15 mounted in the recirculating plant growing mechanism are driven under PLC control to their home positions. In their home positions three LED light bars 6 in the group are parked next to each other with zero offset distance between them relative to the Y-Axis of the prescribed conveying path on the Y-Axis portion of their groups two supporting LED light bar track assemblies 7 see FIG. 15 on one side of conveyor drive assembly 128 relative to the X-Axis of the prescribed conveying path, the three other LED light bars 6 in the group are parked next to each other with zero offset distance between them relative to the Y-Axis of the prescribed conveying path on the Y-Axis portion of their groups two supporting LED light bar track assemblies 7 see FIG. 15 on the other side of conveyor drive assembly 128 relative to the X-Axis of the prescribed conveying path. Each group of six LED light bars 6 mounted on each groups two LED light bar track assemblies 7 parked at their home positions are within reach of one of the two LED light bar cleaning sponges 34 and one of the two LED light bar cleaning squeegees 35 mounted on the LED light bar cleaning tray assembly 21 relative to the Y-Axis of the prescribed conveying path when the LED light bar cleaning tray assembly 21 recirculates past them relative to the X-Axis of the prescribed conveying path. When LED light bar 6 cleaning is desired and if the LED light bar cleaning tray assembly 21 is not already locked onto the conveyor drive assembly's 128 two conveying chains 26 the PLC will automatically recirculate the drive assembly's 128 two conveying chains 26 the chain links that the LED light bar cleaning tray assembly 21 is to be lock onto is directly in line with the Z-Axis centerline of the two exit gate assemblies 125 see FIG. 1, FIG. 2, and FIG. 22 then lock the LED light bar cleaning tray assembly 21 onto the conveyor drive assembly's 128 two conveying chains 26 in the location reserved for it. The LED light bar cleaning tray assembly 21 is operable as follows when the LED light bar cleaning tray assembly 21 is locked onto the conveyor drive assembly's 128 two conveying chains 26 the conveying chains can only recirculate in the normal direction of travel. The PLC starts the conveyor drive assembly's 128 two conveying chains 26 recirculating. When the LED light bar cleaning tray assembly 21 is positioned at the two exit gate assemblies 125 there are no LED light bars 6 within reach to push back at the either of the two LED light bar cleaning sponges 34 and either of the two LED light bar cleaning squeegees 35 mounted on the LED light bar cleaning tray assembly 21 and so the cleaning tray mount springs pushing against the rear face of the cleaning tray mounts 110 are holding the mounts in their fully extended positions. As the LED light bar cleaning tray assembly 21 recirculates away from the two exit gate assemblies 125 the two cleaning tray mounts 110 upright dodgers 113 see FIG. 4, FIG. 6, and FIG. 38 encounter the first set of conveyor frame 1 uprights located on either side of the conveyor drive assembly 128 relative to the X-Axis of and the dodging sequence begins; the prescribed conveying path and the dodging sequence begins under the motive power of the conveyor drive assembly's 128 two conveying chains 26 the two cleaning tray mounts 110 upright dodgers 113 gradually push back the two cleaning tray mounts 110 to their fully retracted positions so that the two LED light bar cleaning sponges 34 and the two LED light bar cleaning squeegees 35 recirculate past the first set of conveyor frame 1 uprights located on either side of the conveyor drive assembly 128 relative to the X-Axis of the prescribed conveying path unimpeded, at the same time fresh cleaning solution is being applied to the two LED light bar cleaning sponges 34. When the two cleaning tray mounts 110 upright dodgers 113 have recirculate past the first set of conveyor frame 1 uprights located on either side of the conveyor drive assembly 128 relative to the X-Axis of the prescribed conveying path the cleaning tray mounts 110 are released and the two LED light bar cleaning sponges 34 and the two LED light bar cleaning squeegees 35 make contact with the first group of six LED light bars 6 which are parked at their respective home positions ending the dodging sequence. The two LED light bar cleaning sponges 34 and the two LED light bar cleaning squeegees 35 recirculate down the length of the first group of six LED light bars 6 which are parked at their respective home positions cleaning the light bars, the two cleaning tray mounts 110 upright dodgers 113 see FIG. 4, FIG. 6, and FIG. 38 then encounter the second set of conveyor frame 1 uprights located on either side of the conveyor drive assembly 128 relative to the X-Axis of the prescribed conveying path and the dodging sequence is repeated. The same sequence is repeated at every set of conveyor frame 1 uprights located on either side of the conveyor drive assembly 128 relative to the X-Axis of the prescribed conveying path as the LED light bar cleaning tray assembly 21 recirculates around the prescribed conveying path.

In other embodiments the number of probe slider components 141 and thus the number of probe slider assemblies 140 can be increased or decreased which will change the maximum offset distance between the probe slider assemblies 140, if the number of probe slider assemblies 140 is one then the probe sliders position adjustment assembly 129 is not required and a probe slider component 141 will be locked at the center of the watering station plinth 40 relative to the Z-Axis of the prescribed conveying path. In another embodiment the plurality of probe slider components are pushed and pulled to their desired offset positions by pusher plates connected to actuators the probe sliders position adjustment assembly 129 is not required and locks are installed on the plurality of probe sliders components 141 to hold them in the desired offset positions when the plurality of probe sliders components 141 are not being moved.

[0255] Once conditions 1, 2, 3, 4 and 5 are met the two watering station elevating actuator assemblies 49 under PLC control moves the watering station plinth 40 in an upward direction relative to the Y-Axis of the prescribed conveying path so that the attached plurality of fertigation injection probes 50 and sensors 51 and 52 move towards the conveyor tray assembly 2 located directly above the watering station and pass through slots cut in the base of the its double skin tray 65 and pass through a plurality of media holder fertigation injection probe or sensor penetrations 133 see FIG. 29 machined into the bases of the plurality of media holder components 15 to penetrate the plurality of rooting medias to an optimal distance for fertigation and or water injection and or rooting media variable sampling, the watering station plinth 40 is now in its sample position relative to the Y-Axis of the prescribed conveying path. The watering station assembly 12 is now operable to perform fertigation and or water injection and or rooting media variable sampling tasks. The watering station plinth also acts as a glycol injection station, the two glycol coupler actuator assemblies 53 and 54 see FIG. 12 and FIG. 13 glycol coupling actuator bodies 145 see FIG. 35 are bolted to the watering station plinth 40 two penetrations are machined into the watering station plinth 40 allowing the glycol coupler actuator shafts 146 see FIG. 35 to move in an upward direction under PLC control relative to the Y-Axis of the prescribed conveying path. Glycol coupler actuator assembly 53 is the inlet glycol coupler assembly 53, and glycol coupler actuator assembly 54 is the outlet glycol coupler assembly 54. Mounted and fixed to the end of the inlet glycol coupler assembly's 53 glycol coupler actuator shaft 146 is the inlet glycol coupler 55 see FIG. 12, FIG. 13 and FIG. 35. The inlet glycol coupler 55 shares its body with the cleaning solution inlet coupler 118 see FIG. 12, FIG. 13 and FIG. 35. Mounted and fixed to the end of the outlet glycol coupler assembly's 54 glycol coupler actuator shaft 146 is the outlet glycol coupler 56 see FIG. 12, FIG. 13 and FIG. 35. The outlet glycol coupler 56 shares its body with the cleaning solution outlet coupler 120 see FIG. 12, FIG. 13 and FIG. 35. A flexible hose connection glycol inlet port 59 is provided see FIG. 12 and FIG. 13 and will be connected via a flexible hose to the glycol heat exchanging system not defined herein.

A flexible hose connection cleaning solution outlet port 121 is provided see FIG. 12 and will be connected via a flexible hose to the cleaning solution return system not defined herein. The watering station plinth 40 is still in its sample position relative to the Y-Axis of the prescribed conveying path and the inlet glycol coupler 55 is coupled to the inlet glycol coupler with non-return valve 73 mounted on the base of the double skin tray 65 of the conveying tray assembly 2 being sampled, the act of coupling causes the inlet glycol coupler's non-return valve to open 73, and the outlet glycol coupler 56 is now coupled to the outlet glycol coupler with non-return valve 74 which is mounted on the base of the double skin tray 65 of the conveying tray assembly 2 being sampled, the act of coupling causes the outlet glycol coupler's non-return valve to open 74. Glycol at the optimal root zone temperature for the plant species can now be injected into the thermal reservoir of the double skin tray 65 flushing out the existing glycol in the thermal reservoir of the double skin tray 65. Upon completion of the fertigation and or water injection and or rooting media variable sampling and glycol injection flushing tasks, the two watering station elevating actuator assemblies 49 under PLC control move the watering station plinth 40 in an downward direction relative to the Y-Axis of the prescribed conveying path so that the attached plurality of fertigation injection probes 50 and sensors 51 and 52 move away from the conveyor tray assembly 2 being sampled and move out of the plurality of rooting medias and move out of the plurality of media holder fertigation injection probe or sensor penetrations 133 and move out of the slots cut in the base of the its double skin tray 65 and the watering station assembly 12 is returned to its home position The inlet glycol coupler 55 is now de-coupled from the inlet glycol coupler with non-return valve 73 and the non-return valve is closed. The outlet glycol coupler 56 is now de-coupled from the outlet glycol coupler with non-return valve 74 and the non-return valve is closed. The conveying chains 26 can now be restarted. There exists another method of operation of the watering station assembly's 12 glycol injection station that allows it to operate independently of the watering station elevating actuator assemblies 49. If the above conditions 1, 2, and 3 are met and the watering station assembly 12 is in its home position, the inlet glycol coupling actuator assembly 53 under PLC control moves the inlet glycol coupler 55 in an upward direction relative to the Y-Axis of the prescribed conveying path until it couples with the inlet glycol coupler with non-return valve 73 mounted on the base of the double skin tray 65 of the conveying tray assembly 2 being sampled, the act of coupling causes the inlet glycol coupler's non-return valve to open 73, and the outlet glycol coupling actuator assembly 54 under PLC control moves the outlet glycol coupler 56 in an upward direction relative to the Y-Axis of the prescribed conveying path until it couples with the outlet glycol coupler with non-return valve 74 mounted on the base of the double skin tray 65 of the conveying tray assembly 2 being sampled, the act of coupling causes the outlet glycol coupler's non-return valve to open 74. Glycol at the optimal root zone temperature for the plant can now be injected into the thermal reservoir of the double skin tray 65 flushing out the existing glycol in the thermal reservoir of the double skin tray 65. Once the glycol in the thermal reservoir of the double skin tray 65 has been exchanged, the inlet glycol coupling actuator assembly 53 under PLC control moves the inlet glycol coupler 55 in a downward direction relative to the Y-Axis of the prescribed conveying path so that it de-couples from the inlet glycol coupler with non-return valve 73, the act of de-coupling causes the inlet glycol coupler's non-return valve to close 73 and the inlet glycol coupler 55 is returned to its home position relative to the Y-Axis of the prescribed conveying path. Once the glycol in the thermal reservoir of the double skin tray 65 has been exchanged, the outlet glycol coupling actuator assembly 54 under PLC control moves the outlet glycol coupler 56 in a downward direction relative to the Y-Axis of the prescribed conveying path so that it de-couples from the outlet glycol coupler with non-return valve 74, the act of de-coupling causes the inlet glycol coupler's non-return valve to close 74 and the outlet glycol coupler 56 is returned to its home position relative to the Y-Axis of the prescribed conveying path. The conveyor chains can now be restarted. The watering station plinth 40 also acts as a cleaning solution injection station, the inlet glycol coupler 55 shares its body with the cleaning solution inlet coupler 118. The outlet glycol coupler 56 shares its body with the cleaning solution outlet coupler 120.

[0256] Before the cleaning solution injection station can be operated, the following conditions must be met: [0257] 6. the Z-Axis centerline of the LED light bar cleaning tray assembly 21 must be directly over the Z-Axis centerline of the watering station assembly 12; [0258] 7. The watering station assembly 12 must be in the home position; [0259] 8. The conveying chains 26 must be stopped and not restarted until cleaning solution inlet coupler 118 is returned to its home position home position relative to the Y-Axis of the prescribed conveying path; [0260] 9. The conveying chains 26 must be stopped and not restarted until cleaning solution outlet coupler 120 is returned to its home position home position relative to the Y-Axis of the prescribed conveying path.

[0261] Meeting the following conditions is made possible by the PLC which controls the positions of the all actuators and receives the absolute position encoder feedback from all the actuators for the following tasks: [0262] Record keeping of the absolute position on the conveying chains 26 of the LED light bar cleaning tray assembly 21 locked onto the conveying chains 26 relative to the X-Axis of the prescribed conveying path; [0263] Realtime absolute position of the conveying chains 26 as they recirculate around the prescribed conveying path.

[0264] The cleaning solution injection station operates independently of the watering station elevating actuator assemblies 49. If the above conditions 6, 7, 8, and 9 are met the inlet glycol coupling actuator assembly 53 under PLC control moves the cleaning solution inlet coupler 118 in an upward direction relative to the Y-Axis of the prescribed conveying path until it couples with inlet cleaning solution coupler with non-return valve 158 mounted on the base of the cleaning tray cleaning solution pressure bladder tank 114 of the LED light bar cleaning tray assembly 21, the act of coupling causes the inlet cleaning solution coupler's non-return valve 158 to open, and the outlet glycol coupling actuator assembly 54 under PLC control moves the cleaning solution outlet coupler 120 in an upward direction relative to the Y-Axis of the prescribed conveying path until it couples with the outlet cleaning solution coupler with non-return valve 159 mounted on the base of the cleaning tray cleaning solution pressure bladder tank 114 of the LED light bar cleaning tray assembly 21, the act of coupling causes the outlet cleaning solution coupler's non-return valve 159 to open. cleaning solution can now be injected into the cleaning tray cleaning solution pressure bladder tank 114 flushing out the existing cleaning solution in the cleaning tray cleaning solution pressure bladder tank 114. Once the cleaning solution in the cleaning tray cleaning solution pressure bladder tank 114 has been exchanged, the inlet glycol coupling actuator assembly 53 under PLC control moves the cleaning solution inlet coupler 118 in a downward direction relative to the Y-Axis of the prescribed conveying path so that it de-couples from the inlet cleaning solution coupler with non-return valve 158, the act of de-coupling causes the inlet cleaning solution coupler's non-return valve 158 to close and the cleaning solution inlet coupler 118 is returned to its home position relative to the Y-Axis of the prescribed conveying path. Once the cleaning solution in the cleaning tray cleaning solution pressure bladder tank 114 has been exchanged, the outlet glycol coupling actuator assembly 54 under PLC control moves the cleaning solution outlet coupler 120 in a downward direction relative to the Y-Axis of the prescribed conveying path so that it de-couples from the outlet cleaning solution coupler with non-return valve 159, the act of de-coupling causes the outlet cleaning solution coupler's non-return valve 159 to close and the cleaning solution outlet coupler 120 is returned to its home position relative to the Y-Axis of the prescribed conveying path. The conveyor chains can now be restarted.

[0265] In another embodiment not detailed herein the watering station assembly 20 is mounted on slider mounts that slide on slider bars. One slider bar is bolted between two uprights on one side of the conveying frame 1 relative to the X-Axis of the prescribed conveying path, and one slider bar is bolted between two uprights on opposite side of the conveying frame 1 relative to the X-Axis of the prescribed conveying path. The watering station assembly stations 138 are removed from both sides of the conveyor. The sliders mounts are bolted to and support the watering station elevating actuator bodies 142 relative to the X-Axis of the prescribed conveying path. The watering station assembly 12 is positioned so that its Z-Axis centerline is aligned relative the Z-Axis centerline of the conveyor drive assembly 128, the watering station assembly 12 is positioned relative to the Y-Axis of the prescribed conveying path so that one or more plant retaining conveying tray assemblies 2 can recirculate around the watering station assembly 12 when locked onto the conveyor drive assembly's 128 conveying chains 26 unimpeded when the watering station assembly 12 is in its home position relative to the Y-Axis of the prescribed conveying path. The watering station assembly 12 is now free to slide on the slider bars relative to the X-Axis of the prescribed conveying path. Springs are mounted on the slider bars that cause the watering station 12 to return to its home position relative to the X-Axis of the prescribed conveying path if the watering station 12 is not being pulled away from its home position by a motive force. In this embodiment the watering station plinth 40 has three defined positions relative to the Y-Axis of the prescribed conveying path those being; the home position, the capture position, and the sample position. A capture bar is bolted to the watering station plinth 40 pointing toward the upper tier of conveying trays assemblies relative to the Y-Axis of the prescribed conveying path. The capture bar extends to an optimal height just above the plurality of probe slider fertigation injection probes 50 and the plurality of sensor needle tips 51 and 52 that point upwards relative to the Y-Axis of the prescribed conveying path. The base of the double skin tray 65 is modified, a capture bar penetration is machined into the base of the double skin tray 65 relative to the Y-Axis of the prescribed conveying path. The capture bar penetration is machined in a position in the base of the double skin tray 65 and is of sufficient diameter so that the capture bar can penetrate and move upwards trough the double skin tray 65, a half round capture node of sufficient strength is projected downwards from the machined penetration to sufficient depth to facilitate the capture of the capture bar, the half round node is aligned relative to the Z-Axis of the prescribed conveying path. The watering station assembly 12 is now operable to be captured by and to move when captured by a conveying tray assembly 2 locked on the conveying chains 26 and recirculating above and past the watering station 12 in the normal direction of travel. The base of the cleaning tray cleaning solution pressure bladder tank 114 is modified, a capture bar penetration is machined into the base of the cleaning tray cleaning solution pressure bladder tank 114 relative to the Y-Axis of the prescribed conveying path. The capture bar penetration is machined in a position in the cleaning tray cleaning solution pressure bladder tank 114 and is of sufficient diameter so that the capture bar can penetrate and move upwards trough the cleaning tray cleaning solution pressure bladder tank 114, a half round capture node of sufficient strength is projected downwards from the machined penetration to sufficient depth to facilitate the capture of the capture bar, the half round node is aligned relative to the Z-Axis of the prescribed conveying path. The watering station assembly 12 is now operable to be captured by and to move when captured by a conveying tray assembly 2 locked on the conveying chains 26 and recirculating above and past the watering station 12 in the normal direction of travel. The watering station assembly 12 is now operable to be captured by and to move when captured by a LED light bar cleaning tray assembly 21 locked on the conveying chains 26 and recirculating above and past the watering station 12 in the normal direction of travel. All other functionality of the watering station assembly 12 remains unchanged operating in the same manner as the fully described embodiment above. When fertigation injection and or rooting media sampling and or glycol flushing, or cleaning solution flushing is desired the watering station plinth 40 is moved upward relative to the Y-Axis of the prescribed conveying path to the capture position at a time just before a recirculating conveying tray assembly's 2 X-Axis centerline of the plurality of media holders 15 in the conveying tray assembly 2 arrives over the X-Axis centerline of the watering station assembly 12 the capture node then captures the capture bar when the X-Axis centerline of the plurality of media holders 15 in the conveying tray assembly 2 that is to capture the watering station assembly 12 is directly over the X-Axis centerline of the watering station assembly 12, or just before a recirculating LED light bar cleaning tray assembly's 21 X-Axis centerline arrives over the X-Axis centerline of the watering station assembly 12 the capture node then captures the capture bar when the X-Axis LED light bar cleaning tray assembly's 21 X-Axis centerline that is to capture the watering station assembly 12 is directly over the X-Axis centerline of the watering station assembly 12. At this point the watering station begins to move relative to the capturing conveying tray assembly 2 or relative to the capturing LED light bar cleaning tray assembly 21 under the motive power provided by the conveying chains 26 such that the X-Axis centerline of the plurality of media holders 15 in the capturing conveying tray assembly 2, or such that the X-Axis centerline of the capturing LED light bar cleaning tray assembly 21 remains directly over the X-Axis centerline of the watering station 12. The PLC the speed of the conveyor chains 26 can be reduced to a speed that the PLC calculates allows for completion of the tasks to be performed before the watering station assembly reaches the end of travel limit along the conveying bars relative to the X-Axis of the prescribed conveying path. Once the watering station assembly 12 has moved away from its slider home position relative to the X-Axis of the prescribed conveying path the PLC based upon the tasks to be performed can either raise as long as the above conditions 1, 2, 3, 4 and 5 are met and a conveying tray assembly 2 has captured the watering station assembly 2 the two watering station elevating actuator assemblies 49 under PLC control move the watering station plinth 40 in an upward direction relative to the Y-Axis of the prescribed conveying path to the sample position where fertigation, rooting media sampling, and glycol flushing can be performed, or keep the water station plinth at the capture position and as long as the above conditions 1, 2, and 3 are met raise the inlet glycol coupler 55 and raise the outlet glycol coupler 56 to perform independent glycol flushing if a conveying tray assembly 2 has captured the watering station assembly, or as long as the above conditions 3, 6, 7, 8, and 9 are met raise the cleaning solution inlet coupler 118 and cleaning solution outlet coupler 120 to perform independent cleaning solution flushing if a LED light bar cleaning tray assembly 21 has captured the watering station assembly 2. When the assigned tasks have been performed and before the watering station assembly reaches the travel limit along the conveying bars relative to the X-Axis of the prescribed conveying path. The PLC will lower the watering station plinth 40 to its home position and if necessary lower the inlet glycol coupler 55 and the to its home position and lower the outlet glycol coupler 56 to its home position and if necessary lower the cleaning solution inlet coupler 118 and the to its home position and lower the cleaning solution outlet coupler 120 to its home position. When the watering station plinth 40 moves away from the capture position towards the move position the capture bar is released and the watering station assembly 12 is driven to the home position relative to the X-Axis of the conveyor path by the springs mounted on the slider bars. The watering station assembly 12 is now ready to service another conveying tray assembly 2 or LED light bar cleaning tray assembly 21 if desired.

The number of LED light bars 6 mounted in the LED light bar assembly 123 is twelve. An LED light bar 6 is mounted on and bolted to one of the LED light bar stepper motor assemblies 162 at one end of the Consecutive Conveyor Drive Assembly Upright Pairs the opposite end of the of the same LED light bar 6 is mounted on and bolted to the corresponding and mirrored relative to the X-Axis centerline between the Consecutive Conveyor Drive Assembly Upright Pairs LED light bar stepper motor assemblies 162. The twelve LED light bars 6 are operable to travel around the u-shaped path prescribed by the twelve LED light bar's 6 associated pair of LED light bar tracks 167 relative the Z-Axis and Y-Axis of the prescribed conveying path under PLC control. Each LED light bar stepper motor assemblies 162 provides the PLC with absolute position feedback relative the Z-Axis and Y-Axis of the prescribed conveying path so precise positioning of LED light bar's 6 around the plant canopy is possible. The two LED light bar stepper motor assembly's 162 connected at either end of each LED light bar 6 are always moved contemporaneously and at the same speed by the PLC around the u-shaped path prescribed by the associated pair of LED light bar tracks 167 relative the Z-Axis and Y-Axis of the prescribed conveying path thus the two LED light bar stepper motor assemblies 162 are always in the same relative, but mirrored relative to the X-Axis centerline, positions on the associated pair of LED light bar tracks 167 relative the Z-Axis and Y-Axis of the prescribed conveying path. The two LED light bar height adjustment assembly's 165 are operable under the motive power of the four LED light bar track stepper motors 8 to vary the horizontal component distance from the X-Axis centerline of the conveyor drive assembly 128 of the four LED light bar track assemblies 7 relative the Y-Axis of the prescribed conveying path that are mounted in the LED light bar assembly 123. The four LED light bar track stepper motors 8 are always moved contemporaneously and at the same speed by the PLC so that the horizontal component distance from the X-Axis centerline of the conveyor drive assembly 128 to each of the four LED light bar track assemblies 7 relative the Y-Axis is always equal. Each of the four LED light bar track stepper motors 8 provide the PLC with absolute position feedback of the horizontal component distance from the X-Axis centerline of the conveyor drive assembly 128 to each of the four LED light bar track assemblies 7 relative the Y-Axis. The LED light bars 6 energy output PPFD can be varied under PLC control combining this feature with LED light bars 6 height and position adjustment relative to the plant canopy, and X-Axis Z Axis plant spacing capabilities described herein offers significant electrical energy savings over typical cultivation techniques.

[0273] In another embodiment one light bar height adjustment assembly 165 will be mounted at the X-Axis centerline between the Consecutive Conveyor Drive Assembly Upright Pairs. The at least one light bar height adjustment assembly 165 LED will contain at least one light bar track assembly 7 between the Conveyor Drive Assembly Upright Pairs and at least one LED light bar stepper motor assembly 162 will be mounted on the at least one light bar track assembly 7. At least one LED light bar 6 will be mounted on the at least one LED light bar stepper motor assembly 162.

[0274] In another embodiment the LED light bar track's a u-shaped path will be modified to any chosen path shape that more adequately fits the crop's canopy profile.
