Highland Cloud Forest Terrarium
An open-source weather-mimicking terrarium simulating tepui climates for ~120 cloud forest species.
A 1.5 × 0.6 × 1.1 m insulated acrylic enclosure in Genoa, Italy, that simulates highland cloud forest weather using real-time Colombian meteorological data (time-shifted 15 hours). Marine refrigeration drives nighttime temperatures to ~13.5 °C in a room at 22 °C. About 120 species coexist under the same regime — Heliamphora, highland Nepenthes, Dracula, Sophronitis, New Guinea Dendrobium, Utricularia sect. Orchidioides, and more.
