Abstract

A growing medium for a plant production apparatus utilized in greenhouse crop production is provided. The growing medium comprises a fibrous, non-woven matrix media material wherein the media material is constructed from a plastic material.

First claim

The invention claimed is:

1. A hydroponic plant growth system, the system comprising:
a plurality of hollow grow tubes positioned adjacent to each other;
wherein each said grow tube has a front face, a back face, a right face, a left face opposing said right face, a first end, and an open second end opposing said first end, wherein each grow tube has a length between the first end and the open second end and the front face has a width, and wherein the length of each grow tube is larger than the width of the front face; and
wherein each grow tube has a slot formed in the front face, and wherein said slot is formed along the entire length of said front face of each grow tube from the first end to the second end or to a point approximately four (4″) inches to approximately six (6″) inches from the first end of each grow tube, wherein the entire length of the slot has a width ⅓ to ½ the width of the front face; and
one or more matrix media inserts, wherein each matrix media insert is composed of two halves and are formed of a plastic, fibrous, non-woven matrix media material and wherein the media material is coated in a binding material to slow decomposition and reducing UV damage, wherein said one or more matrix media inserts are insertable into each of the grow tubes; and
wherein said plurality of grow tubes are adapted to each receive said one or more matrix media inserts;
wherein the first end of each grow tube is configured to be positioned vertically higher than the open second end; and
wherein said grow tube allows plants to be inserted between said two halves of said one or more matrix media inserts through said slot; and
at least one pump;
one or more nutrient solution conduits, wherein said at least one pump is operably coupled to said one or more nutrient solution conduits;
one or more nutrient solution emitters, wherein said one or more nutrient solution emitters are operable coupled to said one or more nutrient solution conduits; and
at least one reservoir, wherein said at least one pump is capable of circulating nutrient solutions from said at least one reservoir to the first end of the plurality of grow tubes through said one or more nutrient solution conduits and emitting said nutrient solution from said one or more nutrient solution emitters into the first end of each of the plurality of grow tubes such that said nutrient solution passes through the media matrix inserts and into the reservoir through the open second end of each of the plurality of grow tubes.

2. The hydroponic plant growth system of claim 1 , wherein said slot of each grow tube has a width of approximately 1.5 inches.

3. The hydroponic plant growth system of claim 1 , wherein the second end of each of the grow tubes is configured to be positioned to allow said nutrient solution to drain from the plurality of grow tubes into said at least one reservoir.

4. The hydroponic plant growth system of claim 1 , wherein the two halves of each of the matrix media inserts are contacting each other when placed inside each of the grow tubes.

5. The hydroponic plant growth system of claim 1 , wherein each of the two halves of the matrix media inserts is approximately two inches thick.

6. The hydroponic plant growth system of claim 1 , wherein the two halves of said one or more matrix media inserts has a width, wherein a combined width of the two halves of the matrix media inserts are approximately the internal width of the grow tube.

7. The hydroponic plant growth system of claim 1 , wherein each side of the grow tube is approximately four inches to six inches wide.

8. The hydroponic plant growth system of claim 7 , wherein the width of the front face, back face, right face, and left face of each grow tube is approximately four inches.

9. The hydroponic plant growth system of claim 1 , wherein the matrix media inserts are supported only by the grow tube.

10. The hydroponic plant growth system of claim 1 , wherein said binding material coating said matrix media inserts is a silicone binder.

11. The hydroponic plant growth system of claim 1 , wherein the slot extends substantially the length of the grow tube.

12. The hydroponic plant growth system of claim 1 , wherein the slot extends along the entire length of the grow tube.

13. The hydroponic plant growth system of claim 1 , wherein the grow tube is configured to be supported in a substantially vertical position.

14. A method of growing a plant in a vertical hydroponic plant growth system, the method comprising:
providing a plurality of hollow grow tubes positioned adjacent to each other;
wherein each grow tube has a front face, a back face, a right face, a left face opposing said right face, a first end, and an open second end opposing said first end, wherein each grow tube has a length between the first end and the open second end and the front face has a width, and wherein the length of each grow tube is large than the width of the front face; and
wherein each grow tube has a slot formed in the front face, and wherein said slot is formed along the entire face of the grow tube from the first end to the second end, or to a point approximately four (4″) inches to approximately six (6″) inches from the first end of the grow tube, wherein the entire length of the slot has a width ⅓ to ½ the width of the front face;
providing one or more matrix media inserts per grow tube, wherein each matrix media insert is composed of two halves, wherein said one or more matrix media inserts are insertable into each of the plurality of grow tubes;
wherein said plurality of grow tubes are adapted to each receive said one or more matrix media inserts; and
wherein said one or more matrix media inserts are composed of a plastic, fibrous, non-woven matrix media material and wherein the media material is coated in a binding material to slow decomposition and reducing UV damage;
wherein said grow tube allows one or more plants to be inserted between two of the matrix media inserts through said slot; and
providing at least one pump;
providing one or more nutrient solution conduits, wherein said at least one pump is operably coupled to said one or more nutrient solution conduits;
providing one or more nutrient solution emitters, wherein said one or more nutrient solution emitters are operably coupled to said one or more nutrient solution conduits; and
providing at least one reservoir, wherein said at least one pump is capable of circulating nutrient solutions from said at least one reservoir to the first end of the plurality of grow tubes through said one or more nutrient solution conduits and emitting said nutrient solution from said one or more nutrient solution emitters into the first end of each of the plurality of grow tubes such that said nutrient solution passes through the media matrix inserts and into the reservoir through the open second end of each of the plurality of grow tubes;
inserting one or more plants through said slot and between said two halves of said one or more matrix media inserts; and
growing said one or more plants.

15. The method of claim 14 , wherein said slot of each grow tube has a width of approximately 1.5 inches.

16. The method of claim 14 , wherein the matrix media inserts are supported only by the grow tube.

17. The method of claim 14 , wherein the matrix media inserts are composed of two halves contacting each other when inserted into the grow tube.

18. The method of claim 17 , wherein each half of the matrix media inserts is approximately two inches thick.

19. The method of claim 14 , wherei
