Abstract: A system (100) for producing a plant (35), the system having an indoor environment, a plurality of plant holders (1) for growing and transporting a plant therein, a controller (105) for at least controlling temperature and humidity in the indoor environment. The plant holder has a semi-permeable foil (20) defining a non-planar boundary of an interior space and an exterior space, a reservoir (2), having an amount of liquid for feeding the plant. The reservoir (2) and the semi-permeable foil (20) are arranged to allow the plant to grow in the interior space. The semi-permeable foil (20) has permeation of water vapor.

Abstract: A holder for producing a plant of any one of lettuce, sprout and herbs, having a container and a semi-permeable filter, for defining a closed space for wholly accommodating the plant; a reservoir for holding an amount of liquid in the close space; and a passage which is open during use for supplying the liquid to the plant, wherein the reservoir, the container and the semi-permeable filter are arranged to allow the whole plant to grow in the closed space, wherein the semi-permeable filter has a vapor permeation capacity related to a type of the plant and the content of the reservoir, and wherein the amount of liquid is pre-determined corresponding to the vapor permeation capacity, such that the amount of liquid is sufficient for the plant to be isolated in the closed space from cultivation through to offering for sale.
