4. A hydroponic growing system according to claim 3 , wherein the irrigation system is configured and arranged to supply one or more nutrients to the growing crop within the plurality of support vehicles.
5. A hydroponic growing system according to claim 1 , wherein the support vehicles each contain one or more growing trays which themselves include a growing medium for growing a crop.
6. A hydroponic growing system according to claim 1 , wherein the guideway comprises:
a path or track including one or more bearings, or rollers or wheels, against which a portion of each support vehicle is arranged to roll.
7. A hydroponic growing system according to claim 1 , wherein each support vehicle comprises:
one or more bearings, rollers or wheels, configured and arranged to run in a track of the support structure.
8. A hydroponic growing system according to claim 1 , wherein the drive unit comprises:
pneumatic means, configured as a pneumatic actuator or air ram.
9. A hydroponic growing system according to claim 1 , the system comprising:
a pre-treatment portion and a high care portion, the high care portion having an apparatus for seeding, germinating and growing a crop; and
means for reducing contamination during the seeding, germination and growing of the crop.
10. A hydroponic growing system according to claim 9 , wherein:
the apparatus for seeding, germinating and growing a crop is raised above a ground level.
11. A hydroponic growing system according to claim 10 , comprising:
antimicrobial paint on the apparatus within the high care portion of the system.
12. A hydroponic growing system according to claim 11 , in which the antimicrobial paint contains silver.
13. A hydroponic growing system according to claim 9 , in which the high care portion comprises:
means for reducing ethylene from an environment of the high care portion.
14. A hydroponic growing system according to claim 9 , comprising in combination:
means for controlling an environment in the high care portion of the system, the means for controlling the environment being located remote from the growing system.
15. A hydroponic growing system according to claim 9 , comprising:
means for sensing and monitoring an environment within the high care portion.
16. A method of growing a crop hydroponically using a hydroponic growing system, the hydroponic growing system including, a support structure including a plurality of vertically spaced levels, wherein each level includes, a plurality of support vehicles configured to contain a growing crop in use, a plurality of growing stations arranged in a series from an initial growing station to a final growing station, each growing station being configured to be occupied by one of the plurality of support vehicles, and each growing station includes an irradiating apparatus for irradiating, with a light source, the growing crop in the support vehicle occupying the growing station, a guideway configured to guide movement of the support vehicles between the initial growing station and the final growing station, and a drive unit configured, in use, to periodically engage and move a support vehicle occupying the initial growing station to a next growing station in the series such that each of the other support vehicles on the guideway are pushed one growing station along in the series, the method comprising:
on one or more of the plurality of levels, periodically using the drive unit to move a support vehicle occupying the initial growing station to the next growing station in the series, pushing the other support vehides on the guideway aWepsehed one growing station along in the series.
17. A method according to claim 16 , further comprising:
removing a support vehicle occupying the final growing station and inserting another support vehicle into the initial growing station.
18. A method of growing crops in a high care environment, the method comprising:
seeding a growing medium with seeds;
germinating the seeds;
growing a crop from the seeds; and
harvesting the crop, the crop being seeded, germinated, grown and harvested in a high care environment within a hydroponic growing system having a support structure including a plurality of vertically spaced levels, wherein each level includes, a plurality of support vehicles configured to contain a growing crop in use, a plurality of growing stations arranged in a series from an initial growing station to a final g rowing station, each growing station being configured to be occupied by one of the plurality of support vehicles, and each growing station includes an irradiating apparatus for irradiating, with alight source, the growing crop in the support vehicle occupying the growing station, a guideway configured to guide movement of the support vehicles between the initial growing station and the final growing station, and a drive unit configured, in use, to periodically engage and move a support vehicle occupying the initial growing station to a next growing station in the series, pushing each of the other support vehicles on the guideway one growing station along in the series.
