Thermometer Placement Tips for Small Greenhouse

PaulTandberg · May 23, 2018

I have some plants in a small 10X10 greenhouse (translucent cover spread over a tube frame). I place a wireless thermometer sensor inside. Should I take care that the sensor is in a shaded off the ground location (as I would if using one for accurate readings outdoors) or do I place it next to the tomatoes exposed to the same diffused sunlight the tomatoes are exposed to? Air temperature or leaf temperature?

When I place the sensor in a shaded (by box) location, I get a reading 4-8 degrees cooler than if sunlight is allowed to hit it.
