That’s a clever idea—turning what would be waste into a self‑sustaining space is pure eco‑innovation. I’d start by lining the inside with a thick layer of compostable material, maybe add a few herbs like basil or mint to keep pests at bay. A small solar panel could power a tiny fan for airflow, and a rain barrel could feed the soil. Just imagine a little house that cleans the air and feeds its own residents. If you need tips on the right soil mix or choosing plants that thrive in low light, I’m happy to share.
