Abstract
A hydroponic system and method for growing plants. The system comprises one or more plant support structures, one or more housing membranes, and one or more frames. The one or more plant support structures hold plant matter and have one or more holes. The one or more housing membranes are air-permeable and water-resistant, house a solution and at least a portion of the one or more plant support structures, and have one or more openings in which at least a portion of the one or more plant support structures fit into. The one or more frames support the one or more housing membranes. Methods for growing plants are also provided.
Claims20
A hydroponic system comprising:
- one or more plant support structures that hold plant matter;
- wherein the one or more plant support structures have one or more holes;
- one or more housing membranes comprising nonwoven, woven, or knitted fabric or sheet that is air-permeable and water-resistant, house a solution and at least a portion of the one or more plant support structures, and have one or more openings into which at least a portion of the one or more plant support structures fit;
- and
- one or more frames that support the one or more housing membranes, wherein each frame borders one or more housing membranes, including along the sides of said one or more housing membranes, while allowing air to enter through said one or more housing membranes.
A hydroponic system comprising:
- one or more plant support structures for holding plant matter;
- one or more housing membranes for housing a solution and at least a portion of the one or more plant support structures;
- one or more frames for supporting the one or more housing membranes, wherein each frame borders one or more housing membranes, including along the sides of said one or more housing membranes, while allowing air to enter through said one or more housing membranes;
- wherein the one or more plant support structures have one or more holes for allowing the solution to reach the plant matter inside of the one or more plant support structures or the roots of the plant matter to extend outside the one or more plant support structures into the housing membrane;
- and
- wherein the one or more housing membranes comprises nonwoven, woven, or knitted fabric or sheet that is air-permeable and water-resistant, and have one or more openings for at least a portion of the one or more plant support structures to fit into.

- one or more frames that support the one or more housing membranes, wherein each frame borders one or more housing membranes, including along the sides of said one or more housing membranes, while allowing air to enter through said one or more housing membranes;
- wherein the one or more plant support structures comprise a soilless plant medium and have one or more holes in the sides or base of the one or more plant support structures;
- wherein the one or more materials are polyolefin, and have a Gurley Hill porosity of from 1 to 100 seconds per 100 cc air, a resistance to water penetration of from 100 to 500 cm of H2O, and a moisture vapor transmission rate of from 400 to 3500 g/m2/day;
- and
- wherein the solution comprises water and nutrients.
