Abstract: A controlled environment agriculture system is provided, in which the system includes an inner layer and an outer layer. At atmospheric conditions, the inner layer is air permeable, water vapor permeable, and liquid water impermeable, and the outer layer is water vapor impermeable and liquid water impermeable. An enclosure defined by the inner layer is disposed within the interior space of an enclosure defined by the outer layer, and a primary spacing is maintained between at least a portion of the outer surface of the inner layer and the inner surface of the outer layer.

Abstract: Some aspects of the disclosure relate to composite materials and cultivation systems with particular utility for use in aquaculture, for example cultivating various species of seaweed. The systems comprise at least one highly tortuous and often micro-fibrous material and at least one material having low tortuosity. These systems may be configured in a variety of shapes and associated with a number of different structures. Some of these composite materials and cultivation systems may be used in both direct and indirect seeding of macroalgae plants such as seaweed.
