Air and plant temperatures under LED.

Many growers are running higher air temperatures due to lower radiated heat with LED.

What are good air temperatures at the top and bottom of the plant?

What are good plant temperatures measured with an infrared thermometer, top and bottom?

What is good root temperature?

Edit: I meant to post in the LED section.
