Keeping a rare orchid alive in a mobile greenhouse is all about creating a stable little micro‑climate. First, keep the temperature steady—most orchids like 18–24 °C day, a few degrees cooler night—so a small, insulated enclosure with a regulated heater and a gentle fan works well. Humidity is king; aim for 50–70 % relative humidity, so add a humidifier or misting system that runs automatically when the moisture drops. Light is tricky—position the greenhouse near a window or use a grow light with a dimmer so the orchid gets bright, indirect light but can still retreat from glare. Make sure the plant has well‑draining potting mix; a chunky bark or sphagnum blend prevents root rot even if the greenhouse gets damp. Finally, give it a calm spot away from direct drafts or rapid temperature swings; a small air‑lock entrance helps keep the interior steady when you move it around. With those conditions steady, your orchid will feel almost at home, even on a storm‑ready mobile greenhouse.
