Full review

A quick read on the greenhouse air

The TempPro TP150 gives a greenhouse or grow shelf a small display for temperature and humidity. That simple visibility can make daily rounds feel grounded because the gardener can see what the space is doing before adjusting shade, vents, fans, or water.

The display includes current readings and high-low records. Those records help show how the greenhouse moved through the day, especially during bright afternoons and cool evenings.

Built for humid plant spaces

The TP150 has an IPX5 high-humidity resistant design, which suits the damp air that can build around trays, pots, and covered growing spaces.

The stand and magnetic back give a few placement choices. It can sit on a shelf, rest near trays, or attach to a metal surface where the display stays visible.
