Sounds like a neat idea – a living billboard that actually feeds people and the city. I’d start by mapping out the structure: a sturdy frame that can hold the weight of soil, plants, and any lights you want to wire in. We’ll need a good drainage plan, maybe a simple tray system that catches excess water so the soil stays moist but not soggy. For the plants, choose low‑maintenance, fast‑growing veggies or herbs that can thrive on a sunny spot. I can set up a drip irrigation line and add a small solar panel to power any LED signs or gentle grow lights. Then we’ll paint the walls in those bright colors, but I’ll use a weather‑resistant primer first so the paint lasts. Once everything’s set up, we’ll test the wiring and water flow before the protest starts. With a bit of planning and some careful tweaks, it can be both a striking statement and a sustainable little food source. Let’s get the measurements and a sketch, and we’ll turn that idea into a solid project.
