Product review (5 stars): Greenhouse remote thermometer.
Using this in mini greenhouse (GH) 4x8x3 with space heater.  Need to track temperatures to know when to open for venting. Was using humidity/temp gauge (good) but it did not tell me the temp at the time, just peaks over the day/night. I tried it out in house and it is accurate.  It is now in GH with heater currently off.  I will startup the heater in very early spring when I move grow light plants (tomatoes and peppers) out to GH for hardening off.  I tried to use it to test a mister but it gets wet and that is not good for it.  I have the heater on bricks and gauges in a colander to keep all off the ground.
