Method for installing a cultivation floor system and cultivation floor system

1. A method for installing a cultivation floor system comprising a cultivation floor on which plant containers are to be placed, which cultivation floor system comprises an ebb/flood watering installation which is configured to alternately cause a supply of water to the cultivation floor and a discharge of water from the cultivation floor, which method comprises:

providing a watertight basin;

placing one or more irrigation lines in the basin, which irrigation lines provide several outflow openings along their length which make it possible for water to flow from the one or more irrigation lines;

connecting a water pump to the one or more irrigation lines;

providing a water-permeable structure in the basin, which structure has a permeable and horizontal top which forms the floor on which plant containers are to be placed, wherein the one or more irrigation lines are covered by the water-permeable structure,

wherein the method comprises the steps of, while the one or more irrigation lines have been placed in the basin and the water pump is connected thereto, supplying water to the one or more irrigation lines by means of the water pump and monitoring the emerging flow of the water from the outflow openings of the one or more irrigation lines in order to check whether the emerging flow is uniform across the one or more irrigation lines in the basin, and, if deviations in the emerging flow are observed, adjusting the effective emerging flow by providing the one or more irrigation lines, in situ, with one or more additional outflow openings or by increasing the dimensions of one or more outflow openings at a location where the emerging flow is considered to be too small and/or by closing one or more outflow openings of the irrigation lines or by reducing the dimensions of one or more outflow openings at a location where the emerging flow is considered to be too large,

wherein the step of providing one or more additional outflow openings or increasing the dimensions of one or more of the outflow openings comprises one or more operations from the list including: drilling, milling, sawing, burning, cutting, or punching.

2. The method according to claim 1 , wherein the method comprises repeating the steps of supplying water, monitoring, and adjusting the emerging flow one or more times until a desired uniform emerging flow of water from the one or more irrigation lines is achieved, followed by providing the water-permeable structure in the basin.

3. The method according to claim 1 , wherein the method comprises providing a tool which is configured to produce or to enlarge the outflow openings, which tool is provided with a frame comprising guide means, which are configured to engage with the irrigation line, which method furthermore comprises placing the tool on the irrigation line and moving the tool along the line, actuating the tool at a location where it is desired to create one or more additional outflow openings or to enlarge the outflow opening in order to increase the effective emerging flow.

4. The method according to claim 1 , wherein the step of placing one or more irrigation lines in the basin comprises placing of one or more irrigation lines, that have a closed and smooth, non-corrugated peripheral wall in the basin, and wherein, the irrigation lines placed in the basin are subsequently provided with outflow openings along their length, in an initial processing step.

5. The method according to claim 1 , wherein the basin has a bottom profile which is produced in a bed comprising a channel in the bottom profile in which an irrigation line is provided and a bottom surface on one or both sides of the channel, sloping towards the channel, wherein the bed is covered by a watertight membrane, after which the irrigation line is placed in the channel.

6. The method according to claim 1 , wherein the irrigation line is a plastic line with a smooth wall.

7. The method according to claim 1 , wherein the one or more outflow openings are formed or enlarged by means of a cut by a saw in the longitudinal direction of the line.

8. The method according to claim 1 , wherein the irrigation line is accommodated in a channel, so that a top portion of the line is exposed, and wherein the one or more outflow openings are formed or enlarged in the exposed top portion of the line.

9. The method according to claim 1 , wherein, after the emerging flow has been made uniform, a permeable mat or cloth is placed over each irrigation line and adjacent surface parts of the basin bottom.

10. A method for installing a cultivation floor system comprising a cultivation floor on which plant containers are to be placed, which cultivation floor system comprises an ebb/flood watering installation which is configured to alternately cause a supply of water to the cultivation floor and a discharge of water from the cultivation floor, which method comprises:

providing a watertight basin;

placing one or more irrigation lines in the basin, which irrigation lines provide several outflow openings along their length which make it possible for water to flow from the one or more irrigation lines;

connecting a water pump to the one or more irrigation lines;

providing a water-permeable structure in the basin, which structure has a permeable and horizontal top which forms the floor on which plant containers are to be placed, wherein the one or more irrigation lines are covered by the water-permeable structure,

wherein the method comprises the steps of, while the one or more irrigation lines have been placed in the basin and the water pump is connected thereto, supplying water to the one or more irrigation lines by means of the water pump and monitoring the emerging flow of the water from the outflow openings of the one or more irrigation lines in order to check whether the emerging flow is uniform across the one or more irrigation lines in the basin, and, if deviations in the emerging flow are observed, adjusting the effective emerging flow by providing the one or more irrigation lines, in situ, with one or more additional outflow openings or by increasing the dimensions of one or more outflow openings at a location where the emerging flow is considered to be too small and/or by closing one or more outflow openings of the irrigation lines or by reducing the dimensions of one or more outflow openings at a location where the emerging flow is considered to be too large,

wherein the one or more outflow openings are formed or enlarged by means of a cut by a saw in the longitudinal direction of the irrigation line.
