A horticulture facility, including a grow area, a water loop, a nutrient dosing unit configured to dose nutrients to the feed water for the growth area, a hydrogen peroxide dosing unit, configured to introduce a hydrogen peroxide solution into the water loop; a hydrogen peroxide measurement system configured to determine a hydrogen peroxide concentration in the water loop, the hydrogen peroxide measurement system including a sampling unit having a sampling point downstream of the hydrogen peroxide dosing unit, which hydrogen peroxide measurement system is configured to withdraw discrete liquid samples from liquid in the water loop at the sampling point configured to take samples from the water loop and configured to determine a hydrogen peroxide content of a liquid in the water loop; and wherein the horticulture facility includes a controller unit configured to control the hydrogen peroxide content.

The present disclosure refers to a keratin-based substrate, comprising a keratin derivative and natural biopolymer, where the keratin derivative and natural biopolymer are crosslinked. The present disclosure also refers to a method of forming a keratin-based substrate, comprising (i) mixing a solution of keratin derivative with a solution of natural biopolymer; and (ii) drying the resulting solution of step (i) to obtain the keratin-based substrate. The present disclosure further relates to the use of the substrate as a plant growth medium or hydroponic support medium. In a preferred embodiment, a substrate comprising keratin intermediate filament protein and cellulose nanofibers is provided.

Plants are grown in adjacent rows of trays that are rotated within a pool of a nutrient solution. The roots of the plants are at least partly immersed in the nutrient solution. Each row includes a gap wide enough to receive a single tray from an adjacent row. Using three rows, the plants are planted only in one of the rows, and later the rotation is used to space the planted trays one tray apart. Each tray is a parallelepipedal block with apertures for supporting respective plants. The long sides of the blocks have protrusions for preventing adhesion of the blocks. Airlift pumping circulates the nutrient solution past the roots and maintains at least 80% dissolved oxygen saturation in the nutrient solution. A screen of parallel inflatable tubes provides adjustable shade above the pool.

A seed and/or plant system contains a strand-shaped seed and/or plant carrier suspended on a mounting. The seed and/or plant carrier contains several seed and/or plant locations with seeds and/or plants arranged spaced apart from each other in its longitudinal extension. The seeds and/or the plants are supplied with a liquid via a supply tube. In order for the seed and/or plant locations in the seed and/or plant system to be provided at a distance from one another definable by the manufacturer of the seed and/or plant system in a simple manner, a sleeve is provided on each of the seed and/or plant locations, from which a substrate with the seed and/or the plant is received or receivable and/or which at least partially forms a substrate for the seed and/or the plant, wherein the sleeve is formed from the or around the seed and/or plant carrier.
