This is true for HPS. New lighting tech is changing the game. Controlling ambient temperature for the sake of it is misguided. You need to achieve the correct Leaf Surface Temperature, for optimum photosynthesis and transpiration.
The correct ambient temperature for HPS, cannot be the correct ambient temperature for LED. Without the massive amounts of infrared wavelengths, HPS produce, LED lights need higher ambient temperature, to compensate for the cooling effect of evaporation, from transpiration.
Point is, with new lighting technologies, you need to measure the LST ( cheap infrared laser thermometer) and adjust your ambient, to achieve an LST of 25/26 C.
FYI: Set emissivity to 0.98 on your laser thermometer, for green foliage.
