This container is designed for plant projects in space. It Features 3 walls and a floor. The fourth wall should be covered with plastic or plexiglass. A ceiling is not needed, for the soil is held down by a piece in the container that also allows plants to grow in the spaces in it. No ceiling allows for the exchange of gases as well. The water is inserted through two tubes at the back into spherical reservoirs. They are designed this way so that the adhesive and cohesive forces of water will keep it near the holes, in turn being near the soil where it can diffuse into the soil and plant roots. The tubes can also be plugged with two pieces that will fit inside the tubes and be easy to pull out via the square end.
