A modular plant container includes a top having a plurality of inflow openings for receiving fluid. A bottom has a plurality of outflow openings for allowing the fluid to exit. A structure between the top and the bottom includes openings that allow light to reach a plant within the modular plant container. The structure forms a plurality of fluid paths. Each fluid path extends from one of the inflow openings in the top an associated outflow opening in the bottom. Each fluid path has a gap sized to allow a diverter. The diverter when present, divert fluid to a target location within the modular plant container.
