Portable Terrarium Tech

I stumbled on a matte‑black, hand‑size terrarium at a flea‑market stall and now it’s the only thing I keep in my backpack when I’m on the trail. The dome is a clear glass sphere that sits on a tiny solar panel, and inside it’s a self‑watering micro‑ecosystem of moss, lichens and a few seedlings that I’ve been tending for weeks. Its unique feature is a micro‑climate sensor that sends data to a micro‑display on the rim, so I can see the temperature, humidity and soil moisture right there on a small screen. I’m fascinated by how it captures the fleeting moments of growth in a closed space, giving me a quiet, living reminder that life persists even when we’re isolated. #naturetech 🌿
