Abstract
An irrigation device is provided, the device comprising a container for water consisting of a plurality of surfaces, each surface substantially being either a hydrophilic membrane or impervious to water in all forms, and wherein at least one of the surfaces is substantially a hydrophilic membrane and at least one of the surfaces is substantially impervious to water in all forms.
Claims15
A rooting container comprising a lower layer comprising a biodegradable material and an upper layer comprising a hydrophilic membrane, said lower layer and said upper layer being sealed together at their edges to form a hollow cavity, said hollow cavity containing seeds or seedlings.
The method of rooting seeds or seedlings into an area of growing medium comprising the steps of:
- placing a rooting container onto the area of growing medium, the rooting container comprising a lower layer comprising a biodegradable material and an upper layer comprising a hydrophilic membrane, the lower layer and the upper layer being sealed together at their edges to form a hollow cavity, the hollow cavity containing seeds or seedlings;
- and
- exposing the rooting container to rain or artificial watering.
An irrigation device comprising:
- at least one surface comprising a hydrophilic membrane;
- and
- at least one surface comprising material impervious to water in all forms,
- wherein said surfaces comprise a container for water.
A method for providing water to a growth medium, comprising the steps of:
- providing a device comprising at least one surface comprising a hydrophilic membrane and at least one surface comprising material impervious to water in all forms, said surfaces defining a container for water;
- providing water to the container of the device;
- placing the device in proximity to a growth medium, the at least one surface comprising the hydrophilic membrane being in contact with the growth medium;
- and
- transmitting the water from the device through the at least one surface comprising the hydrophilic membrane and into the growth medium.
A method for providing water to a growth medium, comprising the steps of:
- providing a device comprising at least one surface comprising a nonporous hydrophilic membrane and at least one surface comprising material impervious to water in all forms, said surfaces defining a container for water;
- providing water to the container of the device;
- placing the device in proximity to a growth medium, the at least one surface comprising the hydrophilic membrane being in contact with the growth medium;
- and
- transmitting the water from the device through the at least one surface comprising the hydrophilic membrane and into the growth medium.
A method for providing water to a growth medium, comprising the steps of:
- providing a device comprising at least one surface comprising a nonporous hydrophilic membrane comprising copolyetherester elastomer and at least one surface comprising material impervious to water in all forms, said surfaces defining a container for water;
- providing water to the container of the device;
- placing the device in proximity to a growth medium, the at least one surface comprising the hydrophilic membrane being in contact with the growth medium;
- and
- transmitting the water from the device through the at least one surface comprising the hydrophilic membrane and into the growth medium.
