  • Wall structure adapted for aqueously grown microgreens
    Patent number: 11659794
    Abstract: 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.
