A crash course in changing the world.
Design concept for PAN(Portable Agricultural Nursery).
I know the picture is a little light, but from top to bottom, the top(Roof) is designed to be staggered with an inlet for piping(preferably made with a cheap, light material) to carry rainwater into the box of the unit. There's also a valve at the top that acts as a toggle between letting the water flow into the soil basin, or allowing it to flow out through an adjacent drain. The roofing is actually connected to the base of the PAN by a singular support. After the roof, basin, and base are assembled, 4 walls and a door can be connected to it through a series of hindges and other clamps. The walls should be constructed of a cheap but sturdy and clear material(I chose plexiglass, for the lack of any better knowledge around the subject), combined with a hardened plastic towards the bottom of the base. The base itself is directly attached to the soil basin via the support. It's a bit of a crude design on the door, but the base is hollowed until stability is more important than portability, in which it could be filled with sand or other material in cases where improvisation is required.
