DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0036] According to an embodiment of the present invention, there is provided a commercial modular plant growing system 100 as shown in FIG. 1. The system 100 includes stacked growing modules 102 for growing plants. Each growing module 102 includes central pipe fastening means 104, as described below, to facilitate releasable fastening with an adjacent growing module 102.

[0037] Advantageously, the fastened modules 102 can be rapidly fastened together, and later released for cleaning and maintenance using the pipe fastening means 104, without the need for tools, skill or strength.

[0038] As can best be seen in FIG. 1b, the growing modules 102 fasten together to form stacked or vertical towers. Each tower can include up to ten to fifteen growing modules 102. The commercial system 100 can include up to ten to one thousand towers watered through top inlets 106 from a central water supply which advantageously enables water quality (e.g. nutrients, pH, etc.) for the towers to be carefully monitored, facilitates cleaning and maintenance, and reduces buying costs for the user.

[0039] The system 100 also includes a common drainage conduit 108 for draining water from the modules 102, at a single point, back to the central water supply. The water supplied from the top inlets 106 is provided to a spreader 110 or shower screen for spreading water to irrigate the plants in the lower modules 102. The spreader 110 can be reversed to form a bung to seal the topmost module 102 at point 112 when not in use.

[0040] Each growing module 102 includes five growing ports 114 in which the plants are located. Each port 114 includes a pot 116.

[0041] As can best be seen in FIG. 2b, the pipe fastening means 104 includes threadably interconnecting pipes 200. Each pipe 200 has a tapered stem 202 with a threaded free end 204 for hand screwing into an adjacent stem 202. At the base, each pipe 200 includes an annular flange 206 terminating the pipe 200.

[0042] As can best be seen in FIG. 2c, each growing module 102 includes a base 208, and a top 210 for topping the base 208. The module base 208 sits on the flange 206 of the centrally located pipe 200, and the top 210 is held in place by the base 208 above. Each top 210 includes recesses 212 for receiving the pots 116 of the ports 114 (see also FIG. 1b). Similarly, each base 208 defines respective aligned recesses 214 to accommodate the plants from a lower module 102.

[0043] For transport, prior to assembly, the tops 210 can be stacked and nested together and the bases 208 can be stacked and nested together.

[0044] FIG. 3 shows the modular plant growing system 100, with central pipe fastening means 104, adapted for residential use and being portable.

[0045] The residential system 100 includes a self-contained irrigator for irrigating the plants. The irrigator includes a water tank 300 for receiving water draining from the modules 102. The 75-litre tank 300 includes an annular, free-turning lid 302 with a supply inlet for receiving fresh water. The irrigator also includes a submersible pump 304, located within the tank 300, for pumping water up through the pipe fastening means 104 to water plants in the modules 102. The pipe fastening means 104 forms a conduit for conveying water from the pump 304 to the spreader 110 in the topmost growing module 102. The irrigator also includes a drain 306 in the lowermost module 102 for draining the water back into the tank 300.

[0046] The pipe 200, base 208, top 210, tank 300, and lid 302 are all integrally formed, preferably by injection molding.

[0047] FIG. 4 shows the modular plant growing system 100, with bayonet fastening means 104, adapted for commercial use.

[0048] As can best be seen in FIG. 5, the bayonet fastening means 104 includes twist lock formations to facilitate twist-locking of the modules 102 together. The twist lock formations include a bayonet fitting, with posts 500 for being received in L-shaped slots 502. The twist lock formations therefore lock a base 208 and a top 210 of each module 102 together, as well as adjacent modules 102 together.

[0049] FIG. 6 shows the modular plant growing system 100, with bayonet fastening means 104, adapted for residential use.

[0050] The residential system 100 includes a self-contained irrigator for irrigating the plants. Once again, the system includes a submersible pump 304, located within the tank 300, for pumping water up through a central conduit 600 for conveying water from the pump 304 to the spreader 110 in the topmost growing module 102. However, the conduit 600 is formed from press-fit (and not threaded) pipes 200 of each module 102.

[0051] Turing to FIG. 7, each growing module 102 includes a base 208, and a top 210 for topping the base 208. The base 208 and top 210 of each module 102 is fastened together using friction-fit formations, namely in the form of engaging posts 700a, 700b. The posts 700a are axially pushed into hollow posts 700b during assembly to form a snug fit, and can be removed by pulling apart during disassembly.

[0052] Turing to FIG. 8, the tank 300 includes a lid 302 with an upper water inlet 800. The lid 302 can include a hinged closure 802 for closing the inlet 800. The lid 302 may also be hinged, and the lid 302 and the closure may be latched.

[0053] The tank 300 also includes a lower drain 804 for draining water from the tank 300. In particular, the drain 804 includes a drainage hole, and a bung for plugging the hole.
