An apparatus,
system, and method for CO2 production and delivery is provided. The generator apparatus supplements or supplies CO2 where it is desired, such as to plants growing in space, particularly within an environment
control system (ECS). The various embodiments of the generator apparatus are designed to withstand
outer space storage, travel, and environmental impacts on a prepared mycelial
mass. One example embodiment comprises dual containers wherein an inner container holds the prepared mycelial
mass and an exterior container further protects the interior container and collects and sequesters condensation. In this example each container has a least one wall having a passive gas filter which permits the transfer of CO2 out of, and
oxygen in, through the first wall and out of the second wall and into an external environment. The generator may be aided by methods and
system components including a cover,
protective barrier, and case.
