A green ECO mat (GECOMAT) for aeroponics and hydroponics comprises at least one fabric green ECO mat of cultivation being woven to have arrayed multiple 3D-coniform-shaped (alike pyramid shape) chambers, and at least one floating member connects to the fabric green ECO mat. The chambers of the mat are positioned seed, and the floating member floats the mat in a space full with fluid in the nature to collect moisture in the fluid to provide for germination of the seed and growth of the plant. The harvesting means moves back the floating member and the mat when growth of the plant is completed.

Disclosed herein is a high growth, high density, closed environment growing system and methods thereof. A method of accelerating plant cell growth in a growing system may include adjusting the lighting in accordance with an identified plant growth stage.

Provided is a growing medium for plants, including a substrate having voids, and a magnetized magnetic particle dispersedly carried by the substrate.

A composition including a plant medium and a poly-oxygenated metal hydroxide that comprises a clathrate containing oxygen gas molecules. The poly-oxygenated metal hydroxide may comprise of a poly-oxygenated aluminum hydroxide. The composition may include one or more nutrients. The composition may be in a solid form, a fluid form, or a combination thereof. The poly-oxygenated aluminum hydroxide is soluble in a fluid. In one embodiment, the poly-oxygenated metal hydroxide composition may have particles having a diameter of 212 m or less, and which may be homogeneous.

Growing system for growing plants, for example vegetables and ornamental plants, includes a container tray (1) which is floatably arranged in a liquid reservoir (14). The container tray (1) is configured to float on nutrient water (6) during use and has at least one opening (4) which is arranged in a tray bottom (2) of the container tray (1) for bringing a growth substrate (11) which is arranged on the container tray (1) into contact with the nutrient water (6). The container tray (1) is a substantially flat container tray (1) which includes an upright tray edge (3), and wherein the at least one opening (4) has an upright opening edge (5) having a height which is such that the growth substrate (11) is situated above a water line of the nutrient water (6) during use.

Some variations provide a biomedia composition comprising: from 50 wt % to 75 wt % total carbon, on a dry basis, according to ASTM D5373, wherein the total carbon is renewable according to ASTM D6866 (.sup.14C/.sup.12C isotopic ratio); from 20 wt % to 40 wt % oxygen, on a dry basis, according ASTM D5373; from 3 wt % to 10 wt % hydrogen, on a dry basis, according to ASTM D5373; and from 0.1 wt % to 2 wt % nitrogen, on a dry basis, according to ASTM D5373, wherein the biomedia composition is characterized by volatile-matter content from 50 wt % to 75 wt %, according to ASTM D3175; wherein the biomedia composition is characterized by ash content from 1 wt % to 25 wt %, according to ASTM D3174; and wherein the biomedia composition is characterized by moisture content from 0 to 75 wt %, according to ASTM D3173. Processes are also described to make and use the biomedia compositions.

A carrier for growing crops, such as lettuce, is disclosed. The carrier floats on water in a pond, and includes at least one floating beam and a carrier connectable to the floating beam, and a number of growth locations for the crops where holders for the crops or roots of the crops extend into the water.
