I use it indoors but it would work equally well in a greenhouse or other outbuilding. It is perhaps a little bit expensive, but you get what you pay for and in this case, it is excellent. Review: Good Product - Quick Delivery - The package arrived very quickly, 2 days on standard delivery. Packaging was execellent and the hygrometer/thermometer was supplied with two alternative mountings for the external probe. It has yet to undergo a rigorous test but has coped with winter sun and freezing temperatures for the past week without a problem.
