Holder for plants and a plant cultivation method
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.
1. A closed-off holder for producing a plant of any one of lettuce, sprout and herbs, comprising:
an integrally formed container formed from a semi-permeable filter material forming a semi-permeable closed-off bag, for defining a closed space for wholly accommodating the plant;
a reservoir for holding an amount of liquid in the closed space;
a substrate holder forming a closable passage above said reservoir which is open during use for supplying the liquid from the reservoir to the plant; and
a separator arranged between the reservoir and said substrate holder;
wherein the reservoir, the container and the semi-permeable filter are arranged to form a closed-off holder and are designed to allow the whole plant to grow in the closed space,
wherein the semi-permeable filter has a vapour permeation capacity in terms of a quantity per unit of time.
2. The holder according to claim 1 , wherein the container and the reservoir form a unit.
3. The holder according to claim 1 , wherein the separator is a liquid barrier preventing flow of liquid out of the liquid reservoir into the container.
4. The holder according to claim 1 , wherein the substrate holder for accommodating roots of the plant is arranged between the container and the reservoir.
5. The holder according to claim 1 , wherein at least one element is arranged in the substrate holder from the group comprising: a rope, a string, a wick, a lamella, which has a moisture-transmitting capacity, for instance on the basis of a capillary action, from the reservoir to the plant.
6. The holder according to claim 1 , wherein the semi-permeable filter is closed to elements entering from outside.
7. The holder according to claim 1 , wherein the reservoir positioned within said integrally formed container.
