A nutrient medium for the cultivation of plants, containing (a) 3 g/l to 18 g/l agar and (b) 0.5 g/l to 3 g/l carrageenan, as well as plant plugs which contain such a nutrient medium, a method for the production of the plant plugs, and a method for the automated or semi-automated cultivation of plants using the plant plugs.

A plant growing container includes a housing comprising side walls defining a cavity and configured for receiving a plant. The housing contains at least two layers of hydrogel separated by at least one layer of spacing material. The container additionally includes an elongated element that penetrates across the at least two layers of hydrogel and across the at least one layer of spacing material. The elongated element is configured as an air channel that transports air from outside the cavity inwards.

The present disclosure discloses a method for tomato soilless cultivation with suspended trough, including four aspects: setting of soilless cultivation substrate trough, preparation of soilless cultivation substrate, efficient and economical grafting and plant management. The efficient and economical grafting includes seedling raising, preparation of new scion, grafting and healing culture. The plant management includes planting, pruning and vine raising, flower and fruit management, and plant type maintenance. the present disclosure utilizes a soilless cultivation substrate trough, which can overcome the shortcomings of poor water retention, difficult control of temperature and water and fertilizer application in substrate bag cultivation and give full play to the characteristics of the cultivation substrate. The use of efficient and economical grafting and supporting plant management methods can optimize plants configuration, simplifying the work content of plant management, and improving the utilization rate of cultivation space.

A method and apparatus for cultivating vegetation at an arid location includes rooting immature vegetation in a mat combined with a super absorbent polymer (SAP) and, in embodiments, fertilizer, sand, and/or soil; placing the mat at the arid location; covering the mat with a perforated, transparent or semi-transparent cover; collecting urine in a water purification system; and providing purified water extracted from the urine to the mat. A water barrier can be placed below the mat. The cover can be placed on or suspended above the mat. SAP, seeds, and/or additional water barriers can be placed between mats in a stack. The opacity of the cover can be increased to emulate shade from natural vegetation. A water distribution system can be included for continued support of the vegetation, and can include a water reservoir and/or at least one solar still.
