The plant pot further includes a substrate space 11 in which a substrate, for example, soil is accommodated. A bounding wall portion 2A, 2B bounds a part of the second space 11. Drainage openings 13 are located in the bottom 5 of this bounding wall portion 2B next to the gel space 7. The first space 7 is partly bounded by a further bounding wall portion 2D, 2E of the bounding wall 2. Aeration openings 14 are located in this further bounding wall portion. The gel grains 9 are contained in a pad which further includes a flexible separation sheet 15 which forms a root-permeable separation between the gel and soil during use. ## Claims ### Claim 1 A plant pot comprising a bounding wall forming an open-top pot and including a bottom that bounds the under side of the pot as well as a side wall, the bottom forming the complete part of the bounding wall that is present between the side wall, the bounding wall having at least a single opening and a hydrating gel filled first space which is located within the bounding wall, as well as a second space filled with a substrate different from gel, where the second space is partly bounded by a bounding wall portion of the bounding wall, wherein the opening is located in said bounding wall portion and forms a drainage opening for draining a surplus of nutrient water and/or water that cannot be absorbed by the gel during use. ### Claim 2 (depends on 1) A plant pot as claimed in claim 1, wherein the drainage opening is situated in or near a lower bounding edge of the bounding wall portion. ### Claim 3 (depends on 2) A plant pot as claimed in claim 2, wherein the drainage opening bounds the lower bounding edge or is located at the height of the lower bounding edge. ### Claim 4 (depends on 1) A plant pot as claimed in claim 1, wherein the drainage opening is located in the bottom. ### Claim 5 (depends on 1) A plant pot as claimed in claim 1, wherein the first space is partly bounded by a further bounding wall portion of the bounding wall and at least a single aeration opening is located in this further bounding wall portion. ### Claim 6 (depends on 1) A plant pot as claimed in claim 1, wherein the first space is located at a distance over a part of the bottom, where the substrate or a different substrate is present in the space between the first space and the bottom. ### Claim 7 (depends on 6) A plant pot as claimed in claim 6, characterized in that near the first space the bounding wall is provided with at least a single aeration opening for aeration of the gel. ### Claim 8 (depends on 1) A plant pot as claimed in claim 1, wherein at the lower end of the side wall at least a single recess is provided and from this recess to a space underneath a raised part of the bottom a channel is located which is bounded by a vaulted part of the bottom for supplying air to said space. ### Claim 9 (depends on 1) A plant pot as claimed in claim 1, wherein the plant pot comprises a partition wall which is located within the side wall in the plant pot and is connected or attached to or forms part of the bottom, while the first space is located within the partition wall. ### Claim 10 (depends on 9) A plant pot as claimed in claim 9, wherein the partition wall is formed by flexible upright flaps. ### Claim 11 (depends on 9) A plant pot as claimed in claim 9, wherein the partition wall is formed by a part of the bottom and two wall portions spaced apart from each other, where the space between the wall portions is located outside the bounding wall of the plant pot. ### Claim 12 (depends on 11) A plant pot as claimed in claim 11, wherein at the lower end of the side wall at least a single recess is provided and from this recess to a space underneath a raised part of the bottom a channel is located which is bounded by a vaulted part of the bottom for supplying air to said space and wherein the aeration opening is located in the inner wall portion of the two wall portions and the space between the wall portions is connected to the environment via the channel for aeration of said space. ### Claim 13 (depends on 11) A plant pot as claimed in claim 11, wherein the lower part of the inner wall portion and the part of the bottom within the partition wall are closed. ### Claim 14 (depends on 1) A plant pot as claimed in claim 1, wherein a separation sheet is located between the top of the first space and the second space. ### Claim 15 (depends on 1) A plant pot as claimed in claim 1, wherein the plant pot comprises an open-top inner pot which is present in said plant pot and in which the first space is present. ### Claim 16 (depends on 1) A plant pot as claimed in claim 1, wherein the plant pot includes a plate that has a closed plate bottom and a raised plate wall, which plate is located underneath the bottom and around the lower part of the side wall, and a third space is located between the plate wall and the lower part of the side wall. ### Claim 17 (depends on 16) A plant pot as claimed in claim 16, wherein the plate is detachably connected to the plant pot. ### Claim 18 A plant pot provided with a bounding wall which forms an open-top pot and comprises a bottom that bounds the under side of the pot as well as a side wall, where the bottom forms the complete bounding wall portion that is located between the side wall and is provided with at least a single opening, and where on or above at least part of the bottom evenly distributed swellable hydrating gel is present, wherein the plant pot comprises an upright partition wall which forms a separation between two spaces above the bottom and is connected or attached to or forms part of the bottom, where in either of the spaces the gel is present and in the other space no gel is present, and in that the opening is located in the part of the bottom where no gel is present on or above the bottom and forms a drainage opening for draining the surplus of nutrient water and/or water that cannot be absorbed by the gel during use. ### Claim 19 (depends on 11) A plant pot as claimed in claim 11, wherein the plant pot includes a plate that has a closed plate bottom and a raised plate wall, which plate is located underneath the bottom and around the lower part of the inner one of the two wall portions of the partition wall, and a third space is located between the plate wall and the lower part of the inner wall portion. ### Claim 20 (depends on 12) A plant pot as claimed in claim 12, wherein the plate is detachably connected to the plant pot.
