Wall structure adapted for aqueously grown microgreens
Crops, for example microgreens, may be aeroponically grown from seed on substrates. The substrates may be seeded with the substrates in a horizontal position, and then arranged vertically for germination and further growth. A gelling material in solution, with the gelling material for example a gellum, may be applied to the substrates, while in the horizontal position, so that the seeds are retained on the substrates when the substrates are moved to a vertical position.
1. A method for use in aeroponic growth of plants, comprising:
applying seeds to a substrate, the substrate in a generally horizontal position;
applying a polymeric material in solution to the seeds and substrate, with the substrate in the generally horizontal position; and
after the polymeric material adheres the seeds in position relative to the substrate, but prior to germination of the seeds, moving the substrate to a generally vertical position.
2. The method of claim 1 , where the polymeric material in solution is a gelling material in solution.
3. The method of claim 2 , wherein the gelling material adheres the seeds in position relative to the substrate upon the gelling material undergoing gelling.
4. The method of claim 3 , wherein the gelling material in solution is applied to the seeds and substrate at a temperature above a gelling temperature of the gelling material.
5. The method of claim 4 , wherein the substrate is a woven material.
6. The method of claim 5 , wherein the substrate is held within a frame.
7. The method of claim 2 , wherein the gelling material in solution comprises between 25 milligrams and 200 milligram of gelling material per liter of fluid.
8. The method of claim 2 , wherein the gelling material in solution comprises between 75 milligrams and 125 milligrams of gelling material per liter of fluid.
9. The method of claim 1 , wherein moving the substrate to the generally vertical position comprises moving the substrate to a generally vertical position in a grow chamber of an aeroponics grow system.
