At what height should I be checking my temps? I have noticed that in my 2' x 2' x 4' box the temperature varies allot at different heights in my room. Top of the box is around 83f, the bottom is around 75f and just under my lights is 87f.
that wasn't my question lol i know you need to measure ambient temps, but if your canopy temp is too hot then you're going to have to make some adjustments.
well thats all i was trying to say... the rest of your temps can be fine like he said but still too hot at the top. not sure why you're trying to fight me on this...
