Abstract: A cultivation floor system has a floor on which plant containers are to be placed. The system includes a watertight basin and a water-permeable structure in the basin, which structure has a permeable top cloth which forms the top side of the floor on which plant containers are placed. The structure includes one or more water-retaining layers. A watering installation supplies water so that water is available for the plants in the plant containers. A perforated film is placed between the permeable top cloth on the one hand and the one or more water-retaining layers on the other hand, which perforated film is made of impermeable film material which is provided with distributed perforations in such a manner that the film reduces the free evaporation surface for water from the one or more water-retaining layers.

Abstract: A cultivation floor system with a floor includes a watertight basin with a watertight groundsheet, a water-permeable structure in the basin, and a permeable top sheet which lies substantially horizontally over the water-permeable structure and forms the top side of the floor on which plant containers are optionally placed. The basin has a water-barrier structure which protrudes above the floor and delimits the compartment which is present on the floor. The water-barrier structure includes a horizontal beam with a top side, a water-barrier profile with a bottom side, and fastening means which fasten the water-barrier profile to the horizontal beam. The top side of the beam is substantially level with the top side of the floor formed by the permeable top sheet. The bottom side of the water-barrier profile is pulled onto the top side of the horizontal beam while clamping the watertight groundsheet and the permeable top sheet.

Abstract: A method for installing a cultivation floor system including a floor on which plant containers are placed, and 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. The method includes: providing a watertight basin; placing one or more irrigation lines in the basin, which irrigation lines provide outflow openings along their length to enable water to flow from the one or more irrigation lines; providing a water pump and connecting that 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 placed, which structure comprises one or more layers of granular material, wherein the one or more irrigation lines are covered by the permeable structure.
