Abstract

A hydroponic grow system and grow method. The system includes growing plants in grow modules that are individually moveable. The plants grow in trays where roots never touch the water supply.

Claims (34)

1. A system comprising:

a grow module that includes:

a growing tray;

a membrane;

a top cover through which oxygen reaches plant roots of a plurality of plants, wherein the top cover comprises a non-transparent material, wherein edges of the membrane create a light blocking seal on edges of the top cover, and wherein the top cover forms vertical shaft openings of a thickness that prevent light from reaching the membrane but through which oxygen reaches the plant roots;

a separator that contacts the membrane at one or more outer edges of the membrane, separating the top cover and the membrane causing fresh air to contact a layer of water that covers the plant roots; and

wherein the growing tray allows a flow of a nutrient water supply

wherein the plant roots are prevented from growing down into the flow of the nutrient water supply.

2. The system of claim 1 , wherein the growing tray includes a buffer mat that includes a wicking mechanism configured to ensure all areas of the membrane are in contact with nutrient water without needing to keep the growing tray level.

3. The system of claim 2 , wherein the buffer mat directly or indirectly floats on top of the nutrient water supply.

4. The system of claim 1 , wherein the growing tray includes an outflow channel positioned precisely at a desired nutrient water level line on the growing tray to prevent nutrient water from rising above the desired nutrient water level line.

5. The system of claim 1 , wherein the nutrient water supply is configured to automatically refill the growing tray with the same amount of nutrient water that is used by plants.

6. The system of claim 1 , wherein a water level of the flow of the nutrient water supply is maintained under a predetermined threshold in order to prevent pooling of water at the top of the membrane.

7. The system of claim 1 , wherein the grow module is configured to keep the nutrient water located in the growing tray always uncontaminated.

8. The system of claim 1 , wherein the top cover physically supports plants and prevents the plants from tipping over.

9. The system of claim 1 , wherein the top cover is made of a material that blocks sunlight from penetrating through and wherein the top cover has a thickness that prevents light from penetrating through plant holes at angles other than 90 degrees with a plane of the top cover.

10. The system of claim 1 , wherein the grow module further comprises a vertical overflow prevention mechanism comprising flow cutouts to prevent clogging of the vertical overflow prevention mechanism.

11. A method for growing plants in a hydroponic system, the method comprising:

growing plants in a grow module that includes:

a growing tray;

a membrane;

a top cover through which oxygen reaches plant roots of a plurality of plants, wherein the top cover comprises a non-transparent material, wherein edges of the membrane create a light blocking seal on edges of the top cover, and wherein the top cover forms vertical shaft openings of a thickness that prevent light from reaching the membrane but through which oxygen reaches the plant roots;

a separator that contacts the membrane at one or more outer edges of the membrane, separating the top cover and the membrane causing fresh air to contact a layer of water that covers the plant roots; and

wherein the growing tray allows a flow of a nutrient water supply

wherein the plant roots are prevented from growing down into the flow of the nutrient water supply.

12. The method of claim 11 , wherein the growing tray includes a buffer mat that includes a wicking mechanism configured to ensure all areas of the membrane are in contact with nutrient water without needing to keep the growing tray level.

13. The method of claim 12 , wherein the buffer mat directly or indirectly floats on top of the nutrient water supply.

14. The method of claim 11 , wherein the growing tray includes an outflow channel positioned precisely at a desired nutrient water level line on the growing tray to prevent nutrient water from rising above the desired nutrient water level line.

15. The method of claim 11 , wherein the nutrient water supply is configured to automatically refill the growing tray with the same amount of nutrient water that is used by plants.

16. The method of claim 11 , wherein a water level of the flow of the nutrient water supply is maintained under a predetermined threshold in order to prevent pooling of water at the top of the membrane.

17. The method of claim 11 , wherein the grow module is configured to keep the nutrient water located in the growing tray always uncontaminated.

18. The method of claim 11 , wherein the top cover physically supports plants and prevents the plants from tipping over.

19. The method of claim 11 , wherein the top cover is made of a material that blocks sunlight from penetrating through and wherein the top cover has a thickness that prevents light from penetrating through plant holes at angles other than 90 degrees with a plane of the top cover.

20. The method of claim 11 , wherein the grow module further comprises a vertical overflow prevention mechanism comprising flow cutouts to prevent clogging of the vertical overflow prevention mechanism.
