Embodiment 1

[0112] This example illustrates the growth of baby spinach on a non-woven substrate using multi-layer flat panels.

[0113] Spinach seeds were germinated and developed into plants on plates using a four-layer structure. The structure used is illustrated in Figures 9 and 10 and includes a frame (905 (with figure 1 L1 in the same)), a polyvinyl chloride (PVC) support layer 1090 with a plurality of openings 1092 in a grid or array; a paper-based soilless growth medium (930, 1030), and a , 1030) on top of a PVC light shielding layer (1020) having a plurality of openings (950) in a grid or array. In this example, the paper-based soilless growing medium supports seed germination and root penetration. Holds the paper in place between the support layer and the shade without stretching or pinning the paper to the bottom support or shade. The openings in the obscuring layer were about 0.32 centimeters (0.125 inches) in diameter and were spaced about 0.95 centimeters (0.375 inches) ap...

Embodiment 2

[0119] This example demonstrates a yield of over 90% of the developed plants grown on the multi-layer plates and low growth of algae on the soilless growth medium.

[0120] Arugula was grown on two flat panels consisting of a metal frame (L1), a bottom support layer (L2), an unstretched polyester-based soilless fabric growing medium surrounded by an adjacent shade layer and The upper layer is fixed in place. Unstretched polyester-based fabric soilless growing media supports seed germination and root penetration through the media. The light-shielding layer and the upper layer are made of opaque, non-transparent white plastic material. The light transmittance (determined by visual inspection) of the unopened or solid portions of the light shielding layer and upper layer is less than the light transmittance through any openings in the light shielding layer. The upper layer, shade, fabric and support layer are sandwiched by two bolt fasteners attached to the frame ends. The ope...

Embodiment 3

[0127] This example demonstrates that under the same test conditions, the evaporation rate of water from a test plate with a shading layer on top of a soilless growth medium is reduced compared to the evaporation rate of water from a plate without a shading layer.

[0128]Measurements were made on a control panel (comprising a polar fleece fabric as disclosed in Harwood, U.S. Patent Publication No. 20140137471) and a test panel (comprising the same polar fleece fabric and an opaque layer (both open and solid) on top of the fabric. ) of the evaporation rate of water. The test equipment consisted of a 0 to 400 lb scale with a data port located under the plate to measure the change in weight over time.

[0129] Measure the air temperature, humidity, and water temperature in the test rig using sensors and a data logger to record the sensor output. The control and test panels were similar in size, measuring approximately (1.5 meters x 0.75 meters; 5 feet x 2.5 feet). Place the pl...

Abstract

Versions of the disclosure relate to multilayer flats for germinating seeds and growing plants in aeroponic or hydroponic farming. The multilayer structure can include a soilless growth medium sandwiched between a support layer and a light barrier layer. The support layer includes openings that allow plant roots to be sprayed with a nutrient solution and the light barrier layer includes openings that allow plants to develop while limiting the growth of harmful algae on the soilless growth medium.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to a Provisional Patent Application entitled "Multilayer Seed Germination and Plant Development Media," filed June 29, 2018, and assigned Serial No. 62 / 692,361. The content of the aforementioned provisional application is incorporated herein by reference. technical field [0003] Embodiments of the present disclosure relate to soilless multi-layered seed germination and plant development media that can be used in aeroponics and hydroponics. Background technique [0004] Aeroponics involves spraying the roots of developing plants with a liquid nutrient solution. The roots of these plants are usually bare and suspended in a growth chamber sprayed with nutrients. In some types of aeroponics, the seeds are placed on the top surface of a fabric that can be supported by a frame. The seeds germinate, and the fabric on the frame is then placed in the growth chamber. In the growth chamber, t...
