Vent: Heat controller in my grow room kept resetting at 74 degrees
I run a small seedling setup in my basement in Ohio, and last month the thermostat kept kicking off at 74 even though I set it for 78. Turns out the sensor was sitting right above the heating mat, so it read the surface temp instead of the air. Moved it to the opposite wall and now it holds steady. Anyone else had a controller that lies because of bad placement?

...and honestly that's just how everything works when you get down to it. I had a space heater in my living room last winter that kept cycling off early, turns out the thermostat was picking up heat from the floor vent underneath it. Moved it three feet and suddenly it acted normal. It's like sensors are always reading the wrong thing, whether it's a grow room or a house, we just assume the numbers are real but they're only as good as where you stick the probe. Kind of makes you wonder how many other little lies we're trusting every day without knowing it.
