Hydroponic growth system

Abstract

A hydroponic growth system comprises grow tubes and a misting assembly. Each of the grow tubes, of a generally hollow cylindrical configuration, are mounted vertically on a support assembly and comprise openings configured on an outer surface of the grow tube for receiving receptacles containing plants. Each of the grow tubes comprise a top vent and a bottom vent. The misting assembly comprises spray tubes inserted into a middle section of the grow tubes to distribute and spray a nutrient solution into an inner surface of each of the grow tubes. The nutrient solution is absorbed by roots of the one or more plants extending into the inner surface of the grow tubes. Unused nutrient solution is drained into a sump positioned beneath the grow tubes via the bottom vents and recirculated within the misting assembly for spraying the nutrient solution to grow the plants.

IV. DETAILED DESCRIPTION OF THE EMBODIMENTS OF THE INVENTION

(8) FIG. 1A exemplarily illustrates a front elevation view of a hydroponic growth system 100 mounted on a support assembly. FIG. 1B exemplarily illustrates a right-side elevation view of a hydroponic growth system 100. The hydroponic growth system 100 comprises a plurality of grow tubes 101 mounted on a support assembly 102. The support assembly 102 is shown as a frame member capable of bearing the load applied by the grow tubes 101. In different embodiments of the present invention, several types of support assemblies 102 may be used based on space requirements or other functional requirements. In the present disclosure, only two such embodiments have been discussed in detail. As used herein, “grow tubes” refer to hollow tubular structures configured to support and nourish a plurality of plants. The grow tubes 101 are of a generally hollow cylindrical configuration. However, it may be appreciated several other configurations, for example, hollow cuboidal, hollow elliptical, etc., may be used instead based on design or other functional requirements. In an embodiment, the grow tubes 101 are mounted vertically on the support assembly 102.

(9) Each of the grow tubes 101 comprise a plurality of openings 103 configured on an outer surface 101a of the grow tube 101. The openings 103 are circular in geometry and configured to receive receptacles/containers containing one or more plants. In an embodiment, the rear surface of the grow tubes 101 are detachably or fixedly attached to the support assembly 102. Each of the grow tubes 101 comprise a top vent 104 and a bottom vent 105. The hydroponic growth system 100 further comprises a misting assembly 106. The misting assembly 106 further comprises a plurality of spray tubes 107. The spray tubes 107 are inserted into a middle section of each of the grow tubes 101 as exemplarily illustrated in FIGS. 1A-1B. The spray tubes 107 contain a nutrient solution that is sprayed into the inner surface 101b of the grow tube 101 as exemplarily illustrated in FIG. 1B. The nutrient solution is sprayed into a section of the grow tube 101 proximal to the top vent 104. The one or more plants placed within the receptacles mounted on the circular openings 103 have roots extending into the inner surface 101b of the grow tube 101. The nutrient solution sprayed into the inner surface 101b of the grow tube 101 is absorbed by the roots of the plant. The unused nutrient solution is drained into a sump 108 positioned beneath the grow tubes 101 via the bottom vent 105 and recirculated within the misting assembly 106.

(10) FIG. 2 exemplarily illustrates a front elevation view of a section of a hydroponic growth system 100 having a different form of support assembly 102. In the embodiment illustrated in FIG. 2, the support assembly 102 is a tensioned cable structure having hangers to mount the grow tubes 101. The rear of the grow tube 101 can be mounted on the support assembly 102 to hang the grow tube 101 vertically or on the front of the grow tube 101 to be hung on a tension cable. If the support assembly 102 is positioned on the front of the grow tubes 101 then the tensioned cables of the support assembly 102 can serve the double purpose of being used to allow vines to grow along the tension cables as exemplarily illustrated in FIG. 2. The openings 103 are circular in geometry and configured to receive receptacles/containers containing one or more plants. Each of the grow tubes 101 comprise a top vent 104 and a bottom vent 105. The hydroponic growth system 100 further comprises a misting assembly 106 having multiple spray tubes 107. The spray tubes 107 are inserted into a middle section of each of the grow tubes 101 as exemplarily illustrated in FIGS. 1A-1B. The spray tubes 107 contain a nutrient solution that is sprayed into the inner surface 101b of the grow tube 101 as exemplarily illustrated in FIG. 1B. The nutrient solutions that is unused is drained into the sump 108 via the bottom vent and recirculated again back to the spray tubes 107 by a pumping mechanism.

(11) FIG. 3A exemplarily illustrates a front elevation view of a grow tube 101 of a hydroponic growth system 100. FIG. 3B exemplarily illustrates a right-side sectional view of a grow tube 101 of a hydroponic growth system 100. The agricultural grow tubes 101 have bottom vents 105 and top vents 104. The bottom vent 105 has an indentation with a through hole thereon to allow venting at the bottom of the grow tube 101. The circular openings 103 on the front of the grow tube 101 are used to insert plants using a circular basket that is received by the circular opening 103. In another embodiment, the circular openings 103 can be square shaped to cooperate with plants having a square root configuration called “grow plugs”. The top vent 104 can include a cap with larger size or smaller size openings as the grow tube 101 requires. The misting assembly 106, exemplarily illustrated in FIGS. 1A and 2, shoots a mist upwards which then falls back down to cover all the plant roots growing inside the grow tube 101. The grow tube 101 can further include a solar powered motor to run the motor of the misting assembly 106, a nutrition solution reclamation circuit or sump 108 as exemplarily illustrated in FIGS. 1A-2 that catches the nutrition solution at the base of the grow tube 101 and recirculates it throughout the hydroponic growth system 100 to recycle the solution.

(12) The foregoing description conveys the best understanding of the objectives and advantages of the present invention. Different embodiments may be made of the inventive concept of this invention. It is to be understood that all matter disclosed herein is to be interpreted merely as illustrative, and not in a limiting sense.
