temperature height

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.

you should be checking it under the lights, right at the canopy of your plants. 87 is too hot by the way...

you want to check ambient heat. heat rises so naturally the temp will be higher when checked higher. i say check right in the middle...

this is not true. u want to check ambient temps.

but what if its fine in the middle, but too hot at the top, his plants could still burn...

the plants will burn if the light is too hot, but that has nothing to do with temps. temps and burning are different things.

sooo you're telling me that lights dont generate the heat that causes temps to rise and plants to burn?

im telling you that the temp above the canopy isnt the temp you measure.

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.

no shit....

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...

man whatever, its not the temps that matter on the tops, its the RADIANT heat and you can test that with the palm method. im done with you...

you started it...
