Where do I put my Temp/Humidity Gauge

Ok so I have a 3x3x7 grow hut, I didn't buy a electric reader but again my question is where to put my temp/humidity gauge?

bottom of floor or in the middle of the room ur choice mine in the middle of my wall so i can see the middle bottom and top and see whats going on in there

Ok thanks I have it at the height of my Plants now

I would put the meters next to the plants and the same height as the plants so you don't read the rising heat or cooler temps below the plants.

just don't put it too close to the lights or you'll get an incorrect reading. Humidity should be pretty much the same throughout the box with good air flow.
