Where to measure humidity and temp

Where do you measure the humidity and temp in the grow room? Iv got 30c 50%rh at about canopy level and 20c 75%rh at pot level. Is this humodity ok for flowering which reading do you go by? Direct Under the lights at the plant top is like 35c is this ok?

I keep my humidity probe a little lower or at canopy level. Your temps/RH are a little high for flower. What kinda light you using? LEDs can handle a little more heat. I would try to get your RH down a little too if you can but anything under 50 with good airflow should be okay

It sounds like your measuring the radiated heat from the bulb, hps yes?
I'm guessing your probe is in direct light?

You need to put a shade on the probe, I use a piece of cardboard tube with a slot cut in it.

That way it measures the actual air temperature.

Under the canopy

In my arse crack. Its like Bangladesh in there.
