Vertical method and apparatus for growing plants

1. A method for growing plants in vertical stacks, comprising:

a) providing vertically stacked horizontal pairs P of plant platforms with inverted light trays resting thereon, each light tray carrying growth promoting light sources;

b) vertically raising the uppermost light tray a desired growing distance S above the uppermost plant platform;

c) vertically raising the uppermost plant platform with the next-below light tray suspended thereunder a desired growing distance S above the next upper platform;

d) repeating step c) in succession whereby a series of platforms with light trays suspended thereunder are vertically suspended and spaced a desired growing distance S from each other;

e) adjusting the growing distance S to accommodate plant growth without re-suspending the plant platforms by adjustably suspending the uppermost light tray and adjustably suspending the lower light trays from the plant platforms;

f) placing watering trays on each suspended plant platform;

g) placing plants to be grown on suspended watering trays under said light trays;

h) regulating said light sources during periods of plant growth and non-growth;

i) supplying water to said plants;

j) removing grown plants from said watering trays; and

k) lowering each plant platform-light tray pair in succession after grown plants are removed whereby said pairs are vertically re-stacked.

2. The method of claim 1 , wherein the plants to be grown are carried by apertured plant lids placed on the watering trays and are watered aeroponically.

3. The method of claim 1 , wherein plants to be grown are carried on perforated plant trays placed on each watering tray.

4. The method of claim 1 , wherein the watering trays are raised and lowered in sequence at a work station in which plants are inserted and removed.

5. A vertical apparatus for growing plants, comprising:

a) a plurality of vertically stacked pairs P of plant platforms with inverted light trays resting thereon, each light tray carrying a growth promoting light source;

b) means to vertically raise the uppermost light tray a desired growing distance S above the uppermost plant platform;

c) means to vertically raise, in succession, the uppermost plant platform and each next below plant platform, each with the next-below light tray suspended thereunder, a desired growing distance S whereby a series of plant platforms with light trays suspended thereunder are vertically suspended and spaced a desired growing distance S from each other;

d) means to adjust the growing distance S to accommodate plant growth without re-suspending plant platforms by adjustably suspending the uppermost light tray from the means to vertically raise the uppermost light tray and adjustably suspending successively lower light trays from the plant platforms; and

e) means to lower each pair P in succession whereby said pairs are vertically re-stacked.

6. The apparatus of claim 5 , including means to place plants to be grown on suspended plant platforms under said light trays.

7. The apparatus of claim 6 , wherein the plants to be grown are carried by apertured plant lids placed on watering trays carried by the plant platforms.

8. The apparatus of claim 7 , wherein means are provided to water the plants aeroponically.

9. The apparatus of claim 5 , wherein plants to be grown are carried by perforated plant trays placed on watering trays carried by the plant platforms.

10. The apparatus of claim 9 , wherein means are provided to supply water to the watering trays for plant growth.

11. The apparatus of claim 5 , including means to regulate said light sources during periods of plant growth and non-growth.

12. The apparatus of claim 5 , wherein means are provided to raise and lower the pairs P in sequence at a work station in which plants are inserted and removed.
