fairly new to growing,and i was wondering where the best place to hang temp/hydro meter in my tent. I have a Vivosun 2x4 tent with 400w Vivosun HPS set at 250w. I have seen it placed below the canopy and right above the canopy. I ask this cause when i put it below canopy I have a great temp/hydro reading,above the canopy it goes out of whack. Much appreciation to response. Thank you.

I try to keep it at canopy level too. Just be sure to check every day or two and adjust or else it will be below canopy before you know it lol.
