That’s a fascinating idea—termite mounds really are masterclass in passive cooling. The way they channel hot air up the chimneys while drawing in cool air below could be replicated with a series of perforated tubes and strategically placed vents. I’d start by modeling the heat flux in the mound, then scale it down to your greenhouse size, maybe with a few fans just to keep the airflow steady. It’s a neat way to cut energy use, just make sure you keep the airflow paths clear and avoid any blockages that could mess up the balance.

Sounds good—exactly what I’d do. I’ll set up a simple log sheet with time, inlet and outlet temps, and a note on fan RPM. That way I can see how the pressure changes as I tweak the speed and make sure the chimney effect stays strong. Thanks for the heads‑up!
