Plant culture container

A container for use in culturing plants in a growth medium, said container comprising a base member having a rectangular bottom and four, substantially vertical walls extending upwardly from the bottom, a top member having a top and four, substantially vertical walls extending downwardly from the top with the distal ends thereof in juxtaposition to the distal ends of the walls of the base member, one of said members having means at the distal ends of the walls thereof and engaging the distal ends of the walls of the other member and supporting the top member on the base member and forming substantially a fluid-tight seal therebetween, said members defining an enclosed space within which said plants may be cultured with part of that space within the base member for holding said medium, the top member having a vent opening therein communicating with said space and the exterior of said container and removable cover means for said vent opening, an air filter mounted on the top member and across said opening, and a removable insert within said part of said space and subdividing that part of the space into a plurality of compartments, said insert being formed by a plurality of partitions having tops and bottoms, said partitions being thicker at the tops thereof than at the bottoms whereby said compartments are smaller at the tops than at the bottoms, some of said partitions having distal ends in juxtaposition to the walls of the base member, each of said distal ends being larger in transverse cross section than is the remainder of the partition thereby forming posts, said posts extending below the remainder of the partitions whereby there is a space below the remainder of the partitions through which liquid can flow.
